NAD combined with collagen creates a powerful duo in the anti-aging market, which reached $535.53 million in 2022. Most people know about collagen supplements that help skin health. NAD+ operates more deeply at the cellular level and supports repair, energy production, and overall rejuvenation. This powerful coenzyme decreases naturally with age—cutting in half about every 20 years after birth.
Research shows that higher NAD+ levels can make aging cells behave like younger ones, which might reverse several age-related issues. NAD+ serves as a vital component in mitochondrial energy production that forms the basis of cellular health. The relationship between NAD+ and skin health goes deeper. NAD+ controls proteins called sirtuins that trigger collagen production—needed for skin's firmness and elasticity. It also supports antioxidant enzymes that reduce damage and lead to smoother, more radiant skin.
This piece examines how NAD+ and collagen complement each other to boost skin health. You'll learn the science behind their anti-aging benefits and practical ways to include both in your daily wellness routine for the best results.
What is NAD+ and how does it relate to skin health?

Nicotinamide adenine dinucleotide (NAD+) is one of the most basic molecules in cellular biology. It plays a vital role in maintaining skin health and works with collagen to improve anti-aging effects.
Understanding NAD+ as a coenzyme
NAD+ is a vital coenzyme found in every cell of the human body. Your body makes it from vitamin B3 metabolism. NAD+ works as an electron acceptor and helps hundreds of metabolic reactions. People who don't have enough NAD+ develop pellagra, which causes dermatitis, dementia, diarrhea, and can lead to death.
NAD+ does more than just help with basic metabolism. It also works as a co-substrate for several important enzyme classes including:
-
Sirtuins, which regulate cellular health and longevity
-
Poly(ADP-ribose) polymerases (PARPs), essential for DNA repair
-
Cyclic ADP-ribose synthases (CD38 and CD157)
-
Mono ADP-ribosyltransferases
This versatility makes NAD+ central to redox balance, energy production, and cellular signaling. So when NAD+ levels drop, many aspects of cellular function suffer, including those that directly affect your skin's appearance and health.
Why NAD+ levels decline with age
Scientists worry most about how NAD+ levels consistently drop with age across species, including humans. Research shows NAD+ concentration drops by at least 50% in human skin samples as we age. Adults have substantially lower NAD+ levels compared to newborns.
Several factors cause this age-related NAD+ decline:
-
NAD+-consuming enzymes become more active, especially those linked to inflammation (CD38) and DNA damage (PARPs)
-
The body produces less nicotinamide phosphoribosyltransferase (NAMPT), which limits NAD+ synthesis
-
The body uses too much NAD+ to fight degenerative conditions and inflammation
By middle age, NAD+ levels can drop well below youthful levels. This leaves skin cells with less energy to repair damage, regenerate, and maintain a strong barrier.
How NAD+ supports skin cell function
NAD+'s connection to skin health has many aspects, which makes nad with collagen a promising pair. NAD+ powers important DNA repair mechanisms through enzymes like PARP1 and sirtuins 1 and 6. This repair helps protect skin exposed to UV radiation and environmental stressors.
NAD+ activates sirtuins that protect collagen in the dermis and help keratinocytes multiply during wound healing. This explains why researchers want to learn about how nad helps with collagen production.
Your skin cells need NAD+ for proper mitochondrial function. It helps improve energy production through SIRT1 and SIRT3 activation and helps recycle damaged mitochondria.
NAD+ helps maintain your skin's natural barrier by supporting vital protein and lipid synthesis. This barrier keeps moisture in and protects against environmental damage.
NAD+ also helps fight oxidative stress by supporting antioxidant pathways. This makes nad anti aging benefits particularly powerful when combined with collagen.
Recent research shows that lower NAD+ levels contribute to many signs of skin aging. These include DNA damage, cellular aging, epigenetic changes, and mitochondrial problems. Understanding how this works lights up why nad+ benefits for skin health have got increasing scientific and commercial attention.
Collagen’s role in skin structure and aging

Collagen is your skin's fundamental architectural protein that makes up almost 75% of its dry weight and acts as the dermis's main structural component. Anyone curious about NAD+ and collagen benefits should learn how these elements work together by understanding collagen's vital role in keeping skin youthful and resilient.
What collagen does for your skin
Collagen creates a complex, interwoven network of fibers that gives your skin structural integrity and tensile strength. This protein builds a support system that makes skin firm and resistant to stretching. Collagen works with other components like elastin and hyaluronic acid to keep skin hydrated, flexible, and resilient.
Your dermis contains types I and III collagen, which make up about 90% of your body's total collagen. Type I collagen fibers create thick, densely packed bundles that deliver tremendous strength. Type III collagen builds thinner, more flexible networks that boost skin's resilience. This balance lets your skin stay strong yet pliable.
Collagen plays a key role in wound healing and tissue regeneration. During repairs, fibroblasts ramp up collagen production to rebuild damaged tissue. These fibroblasts respond to both collagen and NAD+ supplements, making them targets for anti-aging treatments.
How collagen production changes over time
Your body's collagen production drops by about 1% each year starting at age 20. Women experience faster decline after menopause, with studies showing a dramatic 30% drop in collagen synthesis within five years. By age 80, you might produce only half the collagen you made in young adulthood.
Several factors speed up collagen breakdown beyond natural aging:
-
UV radiation creates matrix metalloproteinases that break down collagen fibers
-
Smoking reduces skin's blood flow and triggers inflammation that degrades collagen
-
High sugar intake creates advanced glycation end-products (AGEs) that stiffen collagen fibers
-
Chronic stress boosts cortisol production that can slow collagen synthesis
-
Poor sleep disrupts your skin's natural repair cycles
Wrinkles, sagging, and thinning skin directly reflect these changes in collagen quantity and quality. Your remaining collagen becomes fragmented, disorganized, and less effective, leading to classic aging signs.
Common ways to boost collagen
You can preserve and boost collagen production through various strategies. A protein-rich diet provides essential amino acids like glycine, proline, and hydroxyproline - collagen's building blocks. Bone broth, chicken skin, fish, and egg whites offer readily available collagen precursors.
Vitamin C helps form collagen by hydroxylating proline and lysine amino acids. Antioxidant-rich foods protect existing collagen from damage.
Retinoids, peptides, and growth factors in topical treatments can stimulate fibroblasts to make more collagen. Professional treatments like microneedling, radiofrequency, and laser therapy create controlled damage that triggers collagen regeneration through healing.
Clinical studies show promising results with oral collagen supplements, usually in hydrolyzed form for better absorption. These peptides provide building blocks and signal cells to increase collagen production.
Research suggests exciting connections between NAD+ and collagen production. NAD+ activates sirtuins that guide fibroblast activity and protect against collagen breakdown. This relationship shows why combining NAD+ benefits with collagen supplements could be a powerful way to maintain and regenerate healthy skin.
NAD+ and collagen: Better together?
The relationship between NAD+ and collagen opens up exciting possibilities in skin health research. Recent studies show these compounds work together as powerful partners rather than just side by side.
Does NAD help with collagen production?
Research clearly shows that NAD+ boosts collagen production in multiple ways. We discovered that NAD+ turns on sirtuins (especially SIRT1 and SIRT6) that directly boost genes linked to collagen production. These sirtuins also block matrix metalloproteinase-1 (MMP-1), which breaks down collagen. NAD+ creates a double benefit - it makes new collagen while protecting what's already there.
Our skin's SIRT1 and SIRT6 levels drop as we get older, along with declining NAD+. This explains why aging skin loses about 1% collagen each year. Older adults end up with about 75% less dermal collagen than younger people.
How NAD+ activates fibroblasts
Fibroblasts act as our skin's collagen factories and need NAD+ to work properly. These special cells depend on NAD+ to make collagen and other components of the extracellular matrix.
Low NAD+ levels can push fibroblasts into a senescence-associated secretory phenotype (SASP). They start releasing enzymes that destroy collagen instead of making structural proteins. Bringing NAD+ levels back up reduces senescent cells in dermal fibroblasts and gets them working normally again.
NAD+ also improves how fibroblasts' mitochondria work, giving them energy to make collagen. This happens when SIRT1 changes FOXO1, which kicks off processes that clean up damaged cell parts.
Synergistic effects on elasticity and firmness
NAD+ and collagen together give better results for skin elasticity. Advanced glycation end products (AGEs) make skin stiff and less flexible. NAD+ fights this by starting cleanup processes that remove damaged proteins.
The skin benefits from NAD+'s support of dermal fibroblasts, which make both collagen and elastin. This two-way action keeps skin strong and helps it resist environmental damage.
NAD+ vs collagen: Complementary or competitive?
NAD+ and collagen work as partners, not competitors, through different methods. Collagen gives direct structural support. NAD+ revives skin cells from inside by fixing energy production and repair systems.
Collagen supplements provide building blocks for skin's framework. NAD+ makes sure cells can use these materials properly. In spite of that, NAD+ stands out because it tackles aging at its cellular source instead of just treating surface issues.
This combined approach with NAD and collagen gives us an integrated way to supply raw materials while optimizing how cells use them.
How to boost NAD+ and collagen naturally
Natural methods to boost NAD+ and collagen levels work better than supplements alone to improve skin health. A good understanding of these biological processes helps you create a strategy that supports both NAD+ and collagen working together.
Dietary sources of NAD+ precursors and collagen
Many foods contain high amounts of NAD+ precursors. Edamame beans top the list with 0.47-1.88 mg/100g of NMN. Avocados come next with 0.36-1.60 mg/100g. Broccoli, cucumber, cabbage, and tomatoes have smaller but useful amounts. Seafood and raw meats provide decent levels (0.06-0.42 mg/100g).
People looking for collagen-rich foods can turn to bone broth, chicken skin, fish, and egg whites that provide collagen precursors. Dairy milk contains nicotinamide riboside (NR), and bovine milk has the highest amounts.
Your body needs about 15 mg of niacin each day. You can get this from meat, fish, and dairy products. Some vegetables like spinach and kale help make collagen through their chlorophyll content.
Exercise and its effect on NAD+ levels
Exercise is the quickest way to increase NAD+ levels naturally. Physical activity turns on the enzyme NAMPT in skeletal muscles and reverses the age-related drop in NAD+. This gets the NAD+ salvage pathway going through AMPK activation.
HIIT and resistance training work especially well to boost mitochondrial activity and NAD+ production. Research shows that even regular walking helps maintain healthy NAD+ levels over time.
Lifestyle habits that protect skin health
Diet and exercise matter, but other lifestyle choices affect NAD+ and collagen levels too. Sleep is vital because NAD+ levels change over a 24-hour cycle and depend on sleep patterns. NAMPT becomes more active during dark hours and at night.
You should limit your exposure to things that cause inflammation to keep NAD+ levels up. A poor diet, too much sugar, toxins from the environment, and ongoing stress make the CD38 enzyme break down NAD+ faster. Foods rich in anti-inflammatory compounds and antioxidants help protect against this.
These natural approaches work together to support NAD+ and collagen production. This creates a strong foundation to improve your skin's health and cellular function.
Best supplement and skincare options

You can maximize NAD and collagen benefits through supplements that provide targeted solutions beyond natural methods.
NAD+ supplements: NMN, NR, and IV therapy
Oral NAD+ supplements contain precursors like nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) because pure NAD+ is unstable and doesn't absorb well. These precursors transform into NAD+ inside cells. IV therapy puts NAD+ straight into your bloodstream for quick results, though some people might feel chest tightness and nausea. Many celebrities now use NAD+ IV therapy to boost their energy and focus.
Collagen peptides and topical products
You'll find hydrolyzed collagen supplements as pills, powders, or liquids, sourced from animals (bovine, marine) or plants. Marine collagen matches human collagen better. Collagen peptides work well on skin because their tiny molecule size helps them penetrate deeper.
NAD skincare: What to look for
Sunflower Sprout Extract leads the way in NAD skincare by boosting NAD+ production. NAD+ pairs well with retinol, vitamin C, and hyaluronic acid to give better results. The best formulations stay effective at pH 6-7.5.
Safety and side effects to think about
NAD+ and collagen supplements have proven safe for most people. Collagen studies show minimal side effects. Your NAD+ IV therapy should be given slowly to avoid cramping or nausea. Since supplements don't need FDA approval, third-party testing becomes crucial.
Conclusion
NAD+ and collagen work together powerfully to support anti-aging and skin health. Our research shows how NAD+ operates at the cellular level. It boosts energy production, turns on repair mechanisms, and helps fibroblasts function better - which creates the perfect environment for collagen synthesis. Collagen provides the building blocks that keep skin structured, elastic, and firm.
Both these key components decline with age, which explains why our skin shows more signs of aging as time passes. NAD+ levels drop by half about every 20 years. Collagen production goes down by about 1% each year after age 20. You need to target both elements together to get better results than focusing on just one.
Nature gives us several ways to improve NAD+ and collagen levels. The right food choices rich in precursors help a lot. Regular exercise - especially HIIT and resistance training - combined with good sleep patterns helps maintain optimal levels of both compounds. People who want extra support can use supplements with NMN or NR to boost NAD+, plus hydrolyzed collagen peptides to strengthen skin structure.
Science proves that NAD+ and collagen deliver better results together. NAD+ activates sirtuins that help make more collagen and stop it from breaking down. It also provides the energy cells need to synthesize collagen effectively. So this partnership tackles skin aging at both molecular and structural levels.
This all-encompassing approach does more than improve appearance. It supports your skin's core health functions - from protecting against damage to healing wounds and fighting environmental stress. Learning about NAD+ and collagen's relationship opens up new possibilities. We can now create evidence-based skincare strategies that target aging at its biological root instead of just covering up symptoms.
