Tru Niagen contains one key ingredient, along with some thickening and binding agents. Here's an up-close look at each of these compounds.
Niagen is a branded form of nicotinamide riboside (NR). NR is a water-soluble vitamin that plays a crucial role in many biological processes in the body. It is a precursor to nicotinamide adenine dinucleotide (NAD+), a coenzyme that is involved in many metabolic processes and DNA repair, including energy production and gene expression.
NR is converted into NAD+ in the body through a series of enzymatic reactions. NAD+ is then used by cells to produce energy and carry out other critical biological functions, including regulating gene expression, protecting against cellular stress, and promoting healthy aging. NAD+ levels naturally decline with age, which may contribute to a variety of age-related health issues.
Supplements like Tru Niagen, which contain NR, are marketed as a way to increase NAD+ levels in the body, which may support healthy aging and cellular function.
Microcrystalline cellulose is a type of cellulose that is derived from plant fibers, typically wood pulp and is processed to create fine particles that are uniform in size and shape.
Microcrystalline cellulose is used as a bulking agent to help create tablets and capsules of a consistent size and shape. It is also used as a binder and disintegrant, helping to hold tablets together and to break them down quickly in the digestive tract to release the active ingredients.
In dietary supplements, microcrystalline cellulose may also be used as a bulking agent, as well as a flow agent, to improve the manufacturing process. It is generally considered safe and is not absorbed by the body, passing through the digestive system without being broken down.
Hypromellose, also known as hydroxypropyl methylcellulose, is a semi-synthetic polymer derived from plant cellulose.
One of the main uses of hypromellose in supplements is as a thickening and binding agent. It helps to improve the consistency and texture of supplement tablets and capsules, allowing them to hold their shape and dissolve properly in the digestive system.
Hypromellose is also a vegetarian alternative to gelatin, commonly used as a capsule material. Hypromellose capsules are made from plant-based materials and are suitable for vegetarians and vegans.
Hypromellose is generally considered safe and is not absorbed by the body.
Magnesium stearate is used in dietary supplements to help prevent ingredients from sticking to manufacturing equipment and to ensure they flow smoothly through machines during manufacturing. It can also help to improve the quality and consistency of supplement tablets and capsules.
Vegetable magnesium stearate is a vegetarian and vegan-friendly alternative to animal-derived stearates, such as those derived from beef tallow. It is typically derived from plant sources, such as palm oil or coconut oil.
The manufacturer of Tru Niagen, ChromaDex, claims the following benefits of the product:
Tru Niagen is designed to boost the levels of nicotinamide adenine dinucleotide (NAD+) in the body. NAD+ is an important coenzyme that plays a key role in energy production and a range of other cellular processes. By increasing NAD+ levels, Tru Niagen may help support healthy aging and overall wellness.¹
There are four ways that taking Tru Niagen may benefit heart health:
Increasing Energy Production: The heart is one of the most metabolically active organs in the body and requires a constant supply of energy to function properly. NAD+ plays a key role in producing ATP (adenosine triphosphate), the primary energy source in cells. By increasing NAD+ levels, NAD+ supplements such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) may help improve energy production and support healthy heart function.²
Improving Endothelial Function: The endothelium is the thin layer of cells that lines the inner surface of blood vessels. It plays an important role in regulating blood flow and blood pressure, and dysfunction of the endothelium is a key factor in the development of cardiovascular disease. NAD+ may help improve endothelial function by promoting nitric oxide production, a signaling molecule that helps dilate blood vessels and improve blood flow.³
Supporting Mitochondrial Health: The heart contains a large number of mitochondria, the organelles responsible for producing energy in cells. Mitochondrial dysfunction has been linked to a wide range of cardiovascular diseases, and studies suggest that NAD+ supplementation may help support mitochondrial health and function.⁴
Reducing Inflammation: Chronic inflammation is a key driver of many cardiovascular diseases, including myocardial infarction, atherosclerosis, and heart failure. NAD+ has been shown to have some anti-inflammatory effects and might help reduce inflammation in the heart and blood vessels.⁵
NAD+ is also involved in many cellular processes, including DNA repair, gene expression, and cell signaling. By supporting healthy levels of NAD+, taking Tru Niagen may help promote better cellular health and function and help repair damaged cells.⁶
Excessive oxidative stress can damage muscle tissue and impair muscle function. NAD+ and NR have been shown to have antioxidant effects, which may help reduce oxidative stress and protect muscle tissue from damage. Studies have suggested that NAD+ can help reduce inflammation and oxidative stress, which are two factors that can contribute to delayed-onset muscle soreness (DOMS) and impaired recovery after weight lifting.⁷
Clinical studies of Tru Niagen have generally found it to be well-tolerated, with few reports of significant side effects. However, like any supplement, it may cause side effects in some individuals. Here are some potential side effects of Tru Niagen:
Gastrointestinal Disturbances: Some people may experience mild gastrointestinal side effects, including stomach cramps, diarrhea, and constipation, when taking Tru Niagen.
Allergic Reactions: Some individuals may get an allergic reaction to Tru Niagen or one of its ingredients. Symptoms may include rash, hives, itching, or difficulty breathing.
Interactions with Medications: Tru Niagen may interact with certain medications, such as chemotherapy drugs or immunosuppressants. If you are taking any medications, it is important to talk to your healthcare provider before starting to take Tru Niagen.

Athletes: Tru Niagen helps support healthy metabolism and energy production, which may be beneficial for athletes and active individuals looking to support their physical performance.
People with Metabolic Issues: Tru Niagen may be beneficial for people with metabolic issues, such as insulin resistance or type 2 diabetes, as it may help improve metabolic function and support healthy blood sugar levels.
The manufacturer recommends taking one capsule of Tru Niagen daily with food.
Tur Niagen is just one of a number of popular NAD+ enhancing supplements. Here's an overview of three competitors to help you see how Tru Niagen compares in the marketplace.
Wonderfeel Youngr is a NMN-based supplement designed to use emergent antioxidants and sirtuin activation to slow down aging at a cellular level.
Every capsule of Wonderfeel Youngr contains 450mg of NMN, 2mg of Ergothioneine, 50mg of TransResveratrol, 40mg of Olea25® (25% hydroxytyrosol), and 10mcg of Vitamin D3. This may sound like a lot of extra ingredients, but every single one has an important purpose.
The main difference between Wonderfeel Youngr and Tru Niagen is the form of NAD precursor (NMN vs NR). Both can be effective at boosting NAD levels, but have individual benefits.
You can check out our article on NMN benefits for a full list.
The serving size of Wonderfeel Youngr is a whopping 900mg of NMN per serving, which is a much higher dose than the 300mg of NR from Tru Niagen. This dosage is based on one of the latest human clinical studies, and was found to be the most effective without any negative side-effects.
Life Extension NAD+ Cell Regenerator contains several ingredients that are believed to increase levels of NAD+.
In addition to NR, the primary active ingredient in Life Extension NAD+ Cell Regenerator, the supplement also contains several other ingredients that may support healthy aging and cellular function. These ingredients include resveratrol, quercetin, and fisetin, all of which are known for their antioxidant and anti-inflammatory properties.
Life Extension NAD+ Cell Regenerator is marketed to increase NAD+ levels and support healthy aging, particularly in the brain and other highly metabolically active organs.
Each Life Extension NAD+ Cell Regenerator capsule contains 250 mg of NR, 150 mg of resveratrol, 150 mg of quercetin, and 10 mg of fisetin. Fisetin is a naturally occurring flavonoid, a type of antioxidant found in many fruits and vegetables, such as strawberries, apples, grapes, and onions. It is a type of polyphenol, a group of compounds that are known for their antioxidant and anti-inflammatory properties.
The supplement is designed to be taken daily, with two capsules in the morning and two in the evening.
