Does Nad Increase Collagen
Introduction
Aging is a natural process, but many of us wonder if it can be slowed down—or even reversed—with the help of science. Recently, there has been growing interest in two key supplements for skin health: collagen and NAD⁺. Collagen has long been celebrated as the protein that helps maintain skin elasticity and firmness, while NAD⁺ (nicotinamide adenine dinucleotide) is emerging as a cellular powerhouse that fuels energy production, DNA repair, and overall cellular rejuvenation. But a burning question remains: Does NAD increase collagen? In this blog post, we will explore how these two supplements work, evaluate the scientific evidence behind them, and consider the possibility that boosting NAD⁺ levels may indirectly upregulate collagen production and help reverse signs of skin aging.
Understanding Skin Aging and Collagen
Our skin is our body’s largest organ and a clear indicator of our overall health and vitality. As we age, several changes occur at the cellular level. The skin becomes thinner, looser, and less able to repair itself from daily wear and tear. These visible changes are largely attributed to the decline in collagen—a structural protein that maintains skin firmness and elasticity.
Collagen is produced by specialized cells called fibroblasts. However, as time goes on, the number and activity of these cells diminish, leading to reduced collagen synthesis. External factors such as sun exposure, pollution, and lifestyle habits further exacerbate the natural decline in collagen. While collagen supplements aim to replace the lost building blocks and visibly improve skin texture, they target primarily the surface of the aging process rather than the underlying cellular mechanisms.

Learn MoreThe Role of Collagen in Skin Health
Collagen is one of the main proteins in the extracellular matrix, providing vital support not only for the skin but also for joints, bones, and tendons. As a person ages, the production of collagen naturally decreases. Scientific studies have noted that by the time you reach your 40s, you could have already lost about 25% of your collagen content, which contributes to wrinkle formation, sagging skin, and overall reduced skin elasticity.
Collagen supplements often come in the form of hydrolyzed peptides that are easier for the body to absorb. When regularly integrated into one’s diet, they can help improve skin hydration, reduce fine lines, and support joint health. Yet, their benefits mainly address the visible symptoms of aging. They work on boosting the structural components in the skin but do little to reinvigorate the cell’s internal energy production or repair mechanisms.
The Emergence of NAD⁺ in Anti-Aging
NAD⁺ is a coenzyme found in every cell and is essential for more than 500 enzymatic reactions. It plays a critical role in energy metabolism by facilitating the conversion of food into usable energy (ATP) and also contributes to crucial processes like DNA repair and cell signaling. Studies have shown that the levels of NAD⁺ decline as we age—a decline that has a profound impact on cellular function and vitality.
Research in the field of anti-aging has begun to focus on raising NAD⁺ levels using precursor compounds such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). These supplements help restore youthful levels of NAD⁺, which in turn may accelerate mitochondrial function, enhance DNA repair mechanisms, and even reduce inflammation. Unlike collagen supplements that are largely external or structural, NAD⁺ works deep within cells, targeting the very root causes of aging.

Learn MoreHow NAD⁺ Works Within Our Cells
At the cellular level, NAD⁺ functions as a critical mediator of energy production. It is involved in redox reactions that are essential to converting nutrients into energy. This energy is not only vital for everyday cellular processes but also for enabling a cell to repair damage, replicate, and respond to metabolic stress.
One of the key benefits of NAD⁺ is its function as a cofactor for sirtuins—a family of proteins known for their role in promoting longevity and regulating metabolic pathways. Sirtuins require NAD⁺ to function, and when NAD⁺ is plentiful, these proteins can help slow the aging process and enhance cellular repair. Additionally, NAD⁺ is crucial for the activation of enzymes like poly (ADP-ribose) polymerases (PARPs), which are responsible for repairing DNA damage. By promoting efficient DNA repair, NAD⁺ helps maintain genomic stability, reducing the risk of mutations and other age-related deterioration.
NAD⁺ and Collagen Production: The Connection Revealed
While NAD⁺ itself is not collagen, it plays an indispensable role in ensuring that the cells producing collagen (fibroblasts) remain healthy and fully functional. Healthy cellular processes are directly tied to the ability of fibroblasts to generate collagen. When the cells are energy-deprived or under stress from accumulated DNA damage, collagen production diminishes.
Recent scientific research suggests that restoring NAD⁺ levels may stimulate fibroblast activity and enhance collagen synthesis. For instance, when NAD⁺ levels are replenished, there is a corresponding increase in the activity of sirtuins such as SIRT1 and SIRT6. These enzymes are critical in mediating cellular repair and promoting a youthful epigenetic state, which can lead to an upregulation of collagen-producing genes. In this sense, boosting NAD⁺ does not directly “create” collagen but provides the necessary cellular environment and repair capacity for collagen production to be optimized.

Learn MoreClinical Evidence: Does NAD Increase Collagen?
The clinical evidence is accumulating steadily in support of NAD⁺ supplementation as a means to attenuate age-related cellular decline. Preclinical studies have demonstrated that restoring youthful NAD⁺ levels can reverse signs of aging in various tissue types, including skin. In animal models, researchers have observed that NAD⁺ restoration leads to increased mitochondrial function, enhanced muscle stem cell quality, and improved DNA repair—all factors that contribute to better collagen synthesis.
Human studies are now beginning to echo these findings. Early clinical trials have shown promising results where NAD⁺ precursors not only improve systemic health markers such as cardiovascular function and cognitive ability but also seem to favorably influence skin health. When skin cells have more readily available NAD⁺, they are better equipped to repair UV-induced DNA damage and recalibrate the extracellular matrix, where collagen is a critical component. This suggests that NAD⁺ supplementation could have a beneficial indirect effect on collagen production, potentially improving skin elasticity and reducing wrinkles.
Beyond Skin Deep: NAD⁺ for Holistic Anti-Aging
It is important to realize that NAD⁺’s benefits extend far beyond just skin health. As a master regulator of cellular energy, NAD⁺ supports a wide range of physiological functions. Enhanced NAD⁺ levels contribute to improved metabolic health, help stabilize blood sugar, and even support neurological protection by reducing inflammatory markers in the brain. All these benefits contribute to an overall rejuvenated state, meaning that the improvements in skin appearance are just one piece of a much larger puzzle.
The holistic potential of NAD⁺ means that when you boost cellular energy and repair capacity, many age-related issues can improve simultaneously. This integrated approach could prove particularly valuable for those looking to not only improve their complexion but also boost their overall health, energy levels, and longevity.

Learn MoreStrategies for Boosting NAD⁺ Levels
Given its vital role in health and aging, researchers and practitioners alike have been exploring various ways to safely boost NAD⁺ levels. The most common approach has been supplementation with NAD⁺ precursors, namely nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). These compounds are converted into NAD⁺ in a series of enzymatic reactions, making them effective at replenishing intracellular stores.
Other strategies include lifestyle modifications such as engaging in regular physical exercise—especially high-intensity interval training (HIIT)—maintaining a balanced diet rich in NAD⁺-supporting nutrients, and managing stress levels. Some cutting-edge research is also looking at agents that can inhibit enzymes that accelerate NAD⁺ degradation during the aging process. For example, reducing the activity of CD38, a key NAD⁺ consumer, appears promising in maintaining higher NAD⁺ levels as we age.
Integrative Approaches: Combining NAD⁺ with Collagen Supplements
For those seeking a comprehensive anti-aging strategy, combining NAD⁺ and collagen supplements may offer enhanced benefits. Collagen supplements provide the raw material needed for creating new collagen fibers but may not be fully effective if the cells responsible for producing collagen are energy-depleted or suffering from DNA damage. This is where NAD⁺ supplementation can act as a catalyst for healthier and more efficient cellular function.
By restoring cellular NAD⁺ levels, fibroblasts—the cells responsible for collagen production—are better able to synthesize collagen. Furthermore, the improved mitochondrial function and activation of sirtuins resulting from high NAD⁺ levels promote an optimal cellular environment that supports ongoing tissue repair and regeneration. This “inside-out” approach ensures that not only are you providing your skin with the building blocks it needs but also empowering your cells to use those blocks effectively.

Learn MoreConclusion: Aging with Cellular Health in Mind
The science behind aging is continually evolving, and NAD⁺ has emerged as a vital player in the body’s overall maintenance and repair strategy. While collagen supplements address the external, visible signs of aging by directly providing the ingredients necessary for skin structure, NAD⁺ supplementation tackles aging at a cellular level by enhancing energy production, repairing DNA damage, and supporting the enzymes that drive collagen synthesis.
The answer to the question “Does NAD increase collagen?” is nuanced. NAD⁺ is not a collagen substitute, but by rejuvenating the cells that produce collagen, it creates an optimal environment for collagen production. This integrated approach to anti-aging—combining both NAD⁺ and collagen supplementation—presents a promising strategy for achieving healthier, more resilient skin while also bolstering overall health and vitality.
As clinical research continues to grow, the potential for NAD⁺ therapies to revolutionize our approach to aging becomes increasingly evident. Whether you are looking to combat fine lines and wrinkles or seeking to improve your overall well-being, focusing on cellular health by restoring NAD⁺ levels may be the key to unlocking a more youthful, energetic version of yourself.
