Men's testosterone levels naturally drop about 1% each year after age 30. By the time a man reaches 75, he will have about 30% less testosterone than he had at 25. These changes have led many men to explore herbal remedies low testosterone as supportive options. The numbers are even more striking for older men—about 20% of men over 60 have below-normal testosterone levels, and this figure rises to 50% for those over 80.
Low testosterone levels can substantially reduce quality of life. Many men now prefer natural herbs to boost their testosterone instead of synthetic options. The UK market offers several research-backed natural solutions. A specialised fenugreek extract showed promising results in a 12-week study of men aged 43-70, with participants experiencing a 12.2% increase in total testosterone . Natural alternatives like Tribulus terrestris supplements, Tongkat Ali boosters, and various herbal blends are a great way to get benefits with fewer side effects than pharmaceutical options. This piece explores the science behind these natural solutions that work well for men in their sixties and beyond.
Top 6 Herbal Remedies for Low Testosterone That May Boost Levels Naturally
Men over 60 looking for natural ways to boost testosterone levels can benefit from several herbs backed by scientific studies. These plant-based remedies can work well with fewer side effects than synthetic options.
1. Ashwagandha: Stress relief and hormone support
Ashwagandha (Withania somnifera) serves as the life-blood of Ayurvedic medicine and offers two key benefits for older men with low testosterone. This adaptogenic herb reduces cortisol—the stress hormone that can lower testosterone production. Men aged 40-70 who took ashwagandha extract saw a 14.7% greater increase in testosterone compared to placebo [1]. The study also revealed an impressive 18% increase in DHEA-S, a hormone that helps create testosterone [1].
Scientists have found that ashwagandha supports hormone health through several pathways. The herb affects the hypothalamic-pituitary-gonadal axis, which controls testosterone production [1]. It also helps reduce oxidative stress in the testes, where testosterone production takes place [1]. The herb's withanolides—steroidal compounds—play a key role in balancing hormones.
2. Fenugreek: Libido and strength enhancer
Fenugreek (Trigonella foenum-graecum) has become popular because it improves both libido and physical strength in older men. The herb contains saponins, alkaloids, and flavonoids that can affect testosterone metabolism [2].
A 12-week study showed that men who took fenugreek extract experienced significant increases in both total testosterone concentration in serum and free testosterone index [2]. The herb works in part by freeing testosterone from plasma binding proteins, which might increase free testosterone levels [2]. Men who combined fenugreek supplements with resistance training built more muscle mass and strength while losing body fat [3].
3. Tribulus Terrestris: Traditional testosterone herb
Traditional medicine systems in India and China have used Tribulus terrestris for centuries as a sexual stimulant and testosterone booster [4]. The herb's steroidal saponins, including protodioscin, might influence hormone levels.
Early research suggested Tribulus could increase testosterone, but newer studies paint a different picture. A complete review found that taking 400-750 mg daily for 1-3 months improved erectile dysfunction in three out of five studies [4]. Yet most research shows Tribulus doesn't raise testosterone levels much in men with normal baseline levels [4]. Yes, it is possible that its sexual health benefits come from other mechanisms, like its role as a neurosteroid and its ability to increase nitric oxide production [4].

4. Tongkat Ali (Malaysian Ginseng): Energy and vitality booster
Tongkat ali (Eurycoma longifolia), also known as "Malaysian ginseng," got attention for its effects on energy, stress reduction, and hormone balance. This traditional "anti-ageing" remedy contains "eurypeptides" that can help restore hormonal balance in older men [5].
The herb works by releasing more "free" testosterone from its binding hormone (SHBG) instead of creating new testosterone [5]. Men with low testosterone who took 200 mg extract daily for a month saw improved serum testosterone levels and quality-of-life measures [5]. People who exercise while taking Tongkat ali can build more muscle mass and strength while losing fat faster [5].
5. Horny Goat Weed: Blood flow and sexual health
Chinese medicine has used Horny goat weed (Epimedium species) for centuries as a tonic and aphrodisiac. Icariin, its active compound, works like Viagra by blocking PDE5, an enzyme that limits blood flow to the penis [6].
While it doesn't directly boost testosterone, Horny goat weed can complement testosterone-boosting herbs by improving erectile function through better blood flow. Lab tests show icariin blocks human PDE5 effectively, though it's nowhere near as strong as sildenafil (Viagra) [6]. Studies in rats showed that purified extract helped improve their erectile function [6].
6. Garlic: A surprising testosterone ally
Regular garlic (Allium sativum) might seem unusual for testosterone support, but research reveals several benefits. It improves blood flow by enhancing vascular function and boosting nitric oxide production [7].
Studies in animals show that S-allyl cysteine, found in garlic, might increase testosterone production [7]. Garlic's strong antioxidant properties can protect testicular cells from oxidative damage, which helps maintain testosterone production [7]. While few human studies look directly at garlic's effect on testosterone, research shows it can improve sperm quality and quantity, which often associates with healthy testosterone levels [7].
How These Herbs Work in the Body
Image Source: Europe PMC
Herbal testosterone remedies work through complex interactions with the body's endocrine system. These botanical compounds support natural hormone production through multiple pathways, unlike synthetic hormones. This approach proves especially beneficial for men who experience age-related decline.
Influence on the HPG axis
The hypothalamic-pituitary-gonadal (HPG) axis are the foundations of testosterone production in men. A sophisticated cascade of hormonal signals between the brain and testes drives this biological system [8]. Rather than directly introducing hormones into the bloodstream, testosterone-boosting herbs target this pathway.
Various mechanisms allow herbal extracts to modulate the HPG axis. Some plants contain compounds that help the hypothalamus gland control the entire hormonal system [2]. The modulation restores hormonal balance, which becomes vital for older men as their HPG axis responsiveness naturally declines with age [1].
Men start experiencing this decline around age 30, with testosterone decreasing approximately 1% annually. The ageing process also reduces testicular Leydig cells' response to luteinising hormone, which further compromises testosterone production [1]. Many herbs counteract this effect by improving the sensitivity of these cellular receptors.
Herbs like Ashwagandha possess adaptogenic properties that support the HPG axis through stress regulation. Without this support, stress can suppress testosterone production. These adaptogens work by affecting the pituitary and adrenal glands that produce hormones like cortisol [2].
Stimulation of luteinising hormone (LH)
Luteinising hormone acts as a vital messenger in testosterone production. The pituitary gland releases LH to signal the testes to produce testosterone through Leydig cells [2]. Several herbs boost testosterone levels by increasing LH secretion.
The process often involves the cAMP/Protein kinase A signalling pathway stimulation. LH binding to its receptor (LHCGR) activates adenylate cyclase. This converts ATP to cAMP and activates PKA [1]. Specific compounds in herbs can improve this signalling cascade.
Herbal components affect multiple signalling pathways beyond cAMP/PKA. These include MAPK, JAK/STAT, CAMK, and PKC, which together influence steroidogenesis in testicular Leydig cells [1]. These pathways serve as different routes for herbs to stimulate testosterone production.
Clinical evidence supports this mechanism. To cite an instance, see Chasteberry (Vitex) which stimulates LH production while inhibiting follicle-stimulating hormone (FSH). This dual action helps maintain hormone balance [2].
Anti-oestrogenic effects
Testosterone-supporting herbs often show anti-oestrogenic properties. This counterbalances the relative increase in oestrogen that many men experience as they age. These herbs can indirectly raise testosterone levels by blocking oestrogen's effects [8].
Hormone balance becomes vital because high oestrogen and/or low progesterone levels contribute to hormone imbalance disorders [2]. Some herbal compounds break down excess oestrogen and help eliminate it from the body, as demonstrated by herbs like Dandelion [2].
Some herbs contain compounds that bind to oestrogen receptors (ER-α and ER-β) and act as phytoestrogens. These have milder effects than the body's own oestrogen [3]. Competition for receptor sites reduces oestrogen dominance - a condition where oestrogen levels exceed progesterone [2].
Role of saponins, flavonoids, and alkaloids
Three key compound classes drive the testosterone-boosting effects of herbs:
Saponins appear abundantly in herbs like Tribulus terrestris and play a key role in hormone regulation. These compounds, especially protodioscin, influence testosterone levels [9]. The steroidal saponins' hormone-like structure enables their regulatory effects [10].
Flavonoids share a chemical structure with cholesterol and other steroids. This similarity allows them to influence androgen production in Leydig cells [1]. Scientists have studied these compounds' effects on testosterone since the 1960s, resulting in over 500 published studies [1].
Alkaloids found in herbs like Malaysian ginseng regulate hormones through various mechanisms. Some alkaloids affect dopamine pathways, which then influence prolactin levels and testosterone production [2].
Geographical origin and growing conditions affect the composition and effectiveness of these compounds. Tribulus terrestris from different regions shows varying saponin profiles with different amounts of active compounds like dioscin and protodioscin [9].
Traditional Use vs Modern Research
Image Source: MDPI
Natural testosterone support herbs have been the life-blood of traditional medicine systems long before modern science started testing how well they work. This mix of old-world wisdom and new scientific evidence creates both possibilities and challenges for men who want natural solutions.
Historical use in Ayurvedic and Chinese medicine
These testosterone-supporting herbs trace their roots back thousands of years in ancient healing traditions. Traditional Indian Ayurvedic and Unani medicine systems used these compounds to boost vitality and slow ageing [11]. Ancient texts like the Charaka Samhita, a key Ayurvedic manuscript, describe substances like Shilajit as cure-alls and rejuvenators (rasayanas) that promise a longer life [4].
Ayurvedic practitioners hired herbs like Ashwagandha under the term "Vrisya"—an aphrodisiac that helps with sperm production [4]. Traditional healers prescribed these plants not just for sexual problems but as complete remedies for male vitality and reproductive health.
Traditional Chinese Medicine (TCM) also used herbs like Horny Goat Weed (Epimedium) and Tribulus terrestris to improve sexual function and overall health [12]. TCM experts applied these remedies as part of a complete approach to male health and often combined them with acupuncture and lifestyle changes.
Tribulus terrestris shows how traditional remedies crossed cultural lines—Chinese and Indian medicine systems used it to boost libido, sexual function, and sperm count [8]. These historical uses help guide modern research, but they lack the scientific proof needed in today's healthcare.
Recent clinical trials and findings
Modern science has started to break down these ancient remedies, though results vary. A newer study, published in 2022, found only 13 herbs across 32 studies between 2001 and 2019 that researchers tested for testosterone effects [5]. Only 9 of these 32 studies showed real increases in testosterone levels [5].
Research strongly supports two herbal extracts—fenugreek seed and ashwagandha root/leaf extracts. These showed positive effects on men's testosterone levels [5]. Studies of Malaysian Ginseng (Tongkat Ali) showed improved testosterone levels in regular users [8]. This could help men with low testosterone [13].
Studies back up many traditional uses of herbs like Shilajit [4]. One study showed better sperm health (+37.6% in spermia; +61.4% in total sperm count) and higher testosterone (+23.5%) after 90 days of pure Shilajit treatment [4].
A complete review of Traditional Chinese Medicine (TCM) found these treatments improved erectile function scores and testosterone levels compared to control groups [12]. This suggests value in mixing herbal remedies with modern treatments.
Limitations of current evidence
We have a long way to go, but we can build on this progress. The biggest problem is limited research—only 5.5% of supplements had more than two studies about their effect on testosterone, while 61.5% had no data at all [11].
Research quality also raises concerns. Only 6 out of 32 studies about herbal effects on testosterone showed low bias risk [5]. Most studies focused on young men under 40 (16 out of 32) [5]. This leaves us with little knowledge about how these herbs affect older men.
Study methods vary too much in dosages, extract types, and group sizes [5]. One researcher pointed out that "the true effects of T-boosters are unknown" because no studies compare testosterone therapy directly with herbal boosters [14].
Many popular testosterone-boosting herbs lack scientific explanation for how they work [11]. Sales of herbal products in the United States reached $6.99 billion in 2018 [15], yet these products face nowhere near the same oversight as prescription drugs.
Scientists need to do more research before making final calls about safety and effectiveness [15]. Men looking for natural remedies for andropause should be careful. They should choose products with standardised extracts and some scientific support.
Herbs vs Synthetic Testosterone Boosters
Men with low testosterone face a choice between herbal remedies and synthetic testosterone replacement therapy (TRT). They need to learn about the basic differences, benefits, and potential risks of each option to make informed decisions.
How natural and synthetic boosters differ
Natural testosterone boosters and synthetic options work in completely different ways. Herbal testosterone supplements contain plant-based ingredients, minerals, and amino acids that help the body produce its own hormones [16]. These natural formulas stimulate the body's testosterone production and protect existing testosterone levels instead of adding external hormones [16].
Synthetic testosterone replacement therapy (TRT) takes a different approach. It uses lab-created hormones through injections, gels, or patches [6]. This method adds ready-made testosterone straight into the bloodstream [7].
The biggest difference shows up in how they interact with the endocrine system. Herbal remedies work with the body's natural processes. Synthetic options take control of hormone production, which might lead to dependency as time passes [6].
Benefits of herbal remedies
Herbal remedies give men several advantages in dealing with age-related testosterone decline. These natural options support hormone balance by working alongside the body's endocrine system [16]. Natural boosters don't suppress the body's testosterone production, which makes them great for long-term use [16].
Research shows that herbal formulas safely boost energy levels, stamina, and overall vitality [16]. These supplements also help improve muscle strength and recovery, which works well for active people [16].
Natural testosterone boosters cause fewer side effects than synthetic versions, so they work better for men who have health concerns [6]. The gentle effect on the body allows long-term use without the risks that come with external hormones.
Risks and side effects of synthetic options
Synthetic testosterone options work quickly but come with serious concerns. TRT can create dependency because external hormones might shut down natural production over time [7]. Users often need ongoing treatment to keep their testosterone levels stable [6].
Research links synthetic testosterone to higher risks of heart attacks, strokes, and high blood pressure from hormone imbalances [6]. Users might also experience acne, mood swings, increased red blood cell count, and fertility problems [7].
The hormone conversion risk raises serious concerns. Extra testosterone from synthetic sources can turn into oestrogen, which might cause weight gain and increase prostate cancer risk [6]. TRT patients need regular blood tests and doctor visits to watch for complications [7].
Many men over 60 choose herbal remedies for low testosterone as a safer option. This is especially true for those who have heart problems or prostate issues that synthetic options might make worse.
Safety, Side Effects, and Interactions
Men making health decisions need to know both the benefits and drawbacks of herbal testosterone solutions. The safety profile differs between herbal remedies and pharmaceutical testosterone. This is especially true for men in their sixties and beyond.
Common side effects in older men
Herbal testosterone boosters cause milder reactions than synthetic alternatives, but they still have side effects you should know about. Ashwagandha can cause stomach upset, diarrhoea, and in rare cases, liver damage [17]. Many men experience mild digestive discomfort when they start herbal supplements, especially with fenugreek or tribulus preparations.
Men with existing conditions need extra watchfulness. Those with diabetes should monitor their response as these supplements might change insulin sensitivity and require diabetes medication adjustments [18]. These testosterone-supporting herbs can also raise blood pressure—a big concern if you already have hypertension.
Herbs that affect hormones can trigger mood swings, making you irritable or nervous just like synthetic testosterone [3]. Some men also report headaches, sleep problems, or energy level changes when they first start taking supplements.
Medication interactions to watch for
You need to be extra careful about herb-drug interactions because testosterone interacts with at least 193 different medications [19]. The numbers tell the story: 13 major interactions, 175 moderate ones, and 5 minor ones [19].
Blood thinners are a vital concern. Testosterone-boosting herbs might increase red blood cell production, which could raise clotting risks if you take anticoagulants like warfarin, apixaban, or rivaroxaban [18]. Men taking both need careful monitoring.
Heart medications need similar attention. Beta-blockers or ACE inhibitors might need dose adjustments as testosterone levels rise [18]. Statins like atorvastatin and rosuvastatin also interact with testosterone [19].
Diabetes medications require close monitoring since testosterone affects insulin sensitivity [18]. Men on metformin or insulin might see unexpected changes in blood sugar when they start herbal testosterone support.
Older men often take multiple medications, so talking to healthcare providers about possible interactions is vital, particularly with medications for cholesterol issues, diabetes, or heart conditions [19].
Importance of dosage and standardisation
The biggest problem with herbal testosterone boosters is regulation. These supplements don't face FDA oversight for potency, purity, or safety like pharmaceuticals do [17]. You can't be sure about consistency between products or even different batches.
Quality supplements need standardisation. Herbal extracts with specific active compounds work better than unstandardized ones. [Goldman Laboratories](https://goldmanlaboratories.com/blogs/blog/natural-remedies-male-for-male-andropause-low-testosterone) uses this approach to ensure their formulations maintain reliable potency across batches.
Precise dosing matters with testosterone-supporting herbs. Taking too much zinc can lead to anaemia and immune system problems [17]. Too much vitamin D—often included in testosterone formulas—can cause digestive issues, weakness, confusion, and kidney damage [17].
Many men try to guess their testosterone needs based on symptoms alone. Blood testing is the only way to know for sure [20]. Other conditions can look like low testosterone, including medication side effects, thyroid problems, depression, and drinking too much alcohol [20].
Choosing Quality Herbal Supplements in the UK
Image Source: shutterstock.com
Men looking to buy testosterone-supporting herbs in the UK need to know how to spot quality products. The supplement market offers many choices, but not all products meet the highest standards.
What to look for in UK-sourced products
The Medicines and Healthcare products Regulatory Agency (MHRA) watches over supplement regulation in Britain. Standards differ substantially from pharmaceutical products [2]. Quality products should have transparent labelling that shows exact ingredient amounts rather than hiding behind proprietary blends. You should also choose supplements with third-party testing to verify their purity and potency [21].
Good Manufacturing Practise (GMP) certification proves that UK supplements follow strict production standards [21]. Look for brands that offer evidence-based formulations with ingredients supported by clinical research [2]. Supplement manufacturers can bring products to market without extensive clinical evidence due to loose regulations [2].
Why standardised extracts matter
Standardised herbal extracts give you the same potency and effectiveness in every batch. To name just one example, see quality fenugreek supplements with Furosap® Fenugreek seed extract. These are standardised to 20% protodioscin—one of nature's most effective ingredients to optimise testosterone [22]. This patented process will give a high bioavailability of active compounds [22].
Standardisation means you get the same concentration of active ingredients in each dose. Non-standardised herbs can have varying amounts of beneficial compounds based on growing conditions, harvest timing, and processing methods.
What Goldman Laboratories has in their formulas
Goldman Laboratories shows how evidence-based approach to natural andropause treatment should work. Their formulas use scientifically validated ingredients. The company combines essential nutrients with herbal remedies that clinical research supports [2].
Goldman Laboratories takes a different approach from companies making bold claims. They focus on education and explain the science behind their ingredients [2]. This helps men make smart choices about managing andropause symptoms with herbs like Ashwagandha and other natural remedies for andropause.
Quality testosterone supplements stay away from direct medical claims like "treats erectile dysfunction" or "cures low testosterone." These statements would break regulatory guidelines [2].
Conclusion
Low testosterone levels create major challenges for men in their sixties and beyond. Natural approaches through herbal remedies give men promising alternatives to synthetic hormone replacement. This is especially true when you have concerns about side effects or conflicts with current medications. Research quality varies in different botanicals, but herbs like Ashwagandha and Fenugreek show clear benefits in clinical studies.
The best herbal remedies support the HPG axis, boost luteinising hormone production, and provide anti-oestrogenic effects. On top of that, these natural compounds often help reduce stress, improve circulation, and boost overall vitality.
Men who compare traditional wisdom with modern evidence should set realistic expectations about testosterone-supporting herbs. Traditional use over centuries points to potential benefits. Yet scientific proof remains a work in progress for many popular herbs. The most balanced approach combines both historical backing and current research.
Safety comes first when choosing herbal testosterone support. Men who take medications for heart conditions, diabetes, or blood pressure need to check with their healthcare providers before starting supplements. Those with prostate conditions also need medical guidance to ensure herbs won't worsen their condition.
Quality makes all the difference in how well herbal supplements work. UK men should look for products with standardised extracts, clear labelling, and third-party testing. These features ensure consistent strength and reliable results - crucial given the different rules for supplements versus pharmaceuticals.
Natural approaches for addressing andropause symptoms gain more support as people learn about age-related testosterone decline. So men over 60 now have more choices beyond standard hormone replacement therapy. Using Ashwagandha for testosterone support among other proven botanicals provides a gentle yet effective way to stay vital in later life.
The path to better testosterone levels needs patience, consistency, and a personal approach. Each man's body reacts differently to botanical treatments based on his physiology, lifestyle, and health conditions. This individual nature of herbal medicine shows why it's important to work with healthcare providers who understand both conventional and natural remedies for male andropause.
Herbal testosterone support is just one part of a detailed approach to healthy ageing. Men get the best results when they combine targeted supplements with good nutrition, regular exercise, stress management, and enough sleep. This comprehensive strategy tackles hormone health from all angles while supporting overall wellbeing in the golden years.
Key Takeaways
Natural herbal remedies offer a gentler alternative to synthetic testosterone replacement therapy for men over 60, working with the body's existing hormone production systems rather than replacing them entirely.
• Ashwagandha and fenugreek show strongest clinical evidence - Studies demonstrate 14.7% testosterone increases with ashwagandha and significant improvements with standardised fenugreek extracts.
• Herbs work through multiple biological pathways - They stimulate the HPG axis, boost luteinising hormone production, and provide anti-oestrogenic effects rather than directly adding hormones.
• Quality and standardisation are crucial for effectiveness - Look for UK products with third-party testing, GMP certification, and standardised extracts to ensure consistent potency and safety.
