Is Life Extension NAD+ Cell Regenerator the same ingredient as True Niagen?

Yes. Both use NIAGEN nicotinamide riboside chloride, the patented NR manufactured by ChromaDex. The NIAGEN ingredient is identical. The difference is the brand name on the label and the price. Life Extension licenses NIAGEN and typically sells it at a lower price per capsule.

What is the difference between NR and direct NAD+ supplements?

Nicotinamide riboside (NR) is a precursor molecule. Direct NAD+ is the molecule further along in the same biochemical pathway. Life Extension and True Niagen provide NR. Double Wood and Nutricost provide direct NAD+. These are different molecules.

How many capsules per day does Life Extension NAD+ Cell Regenerator recommend?

One capsule per day, per the label. Each capsule provides 300mg of NIAGEN nicotinamide riboside chloride. Always follow the label instructions.

Is Life Extension NAD+ Cell Regenerator vegetarian?

Yes. The capsule is made from vegetarian cellulose. No gelatin. No animal-derived ingredients are listed on the label.

How does Life Extension NAD+ compare to Pure Encapsulations NR Longevity?

Life Extension is a single-ingredient NR formula (NIAGEN only). Pure Encapsulations NR Longevity is a two-ingredient formula (NIAGEN NR plus resveratrol). Life Extension is typically less expensive. The choice depends on whether you want standalone NR or NR with an added polyphenol cofactor.

Overview: The Mid-Priced NR Option from a Longevity Brand

Life Extension NAD+ Cell Regenerator is a nicotinamide riboside supplement built around NIAGEN, the patented NR ingredient manufactured by ChromaDex. Life Extension is a Florida-based supplement company founded in 1980. The brand focuses on longevity and healthy aging formulas. This bottle is their NR entry. It competes directly with True Niagen, which also uses NIAGEN but typically at a higher price point. The Life Extension version is the value play on the same patented ingredient. For another Life Extension product that takes a different approach to cellular health, see our Life Extension NAD+ overview.

The Honda Accord Analogy

True Niagen is the Acura. Same engine. Nicer interior. Higher sticker price. Life Extension NAD+ Cell Regenerator is the Honda Accord. Same engine (NIAGEN NR). Less flash. Lower price. Both get you to the same destination. One costs more for the badge. One costs less for the same core component. Pick the dealership. The engine is identical.

Formula: NIAGEN Nicotinamide Riboside Chloride, 300mg, Vegetarian Capsules

The Life Extension NAD+ Cell Regenerator label lists NIAGEN nicotinamide riboside chloride as the sole active ingredient at 300mg per capsule, housed in a vegetarian cellulose capsule. The ingredient panel is short. NR. Capsule. A few flow agents. That is the formula. No proprietary blend. No multi-nutrient stack. No added cofactors or B-vitamin complexes. This is a single-ingredient NR supplement in a capsule. The simplicity is the product.

Active Ingredient: NIAGEN Nicotinamide Riboside Chloride, 300mg per capsule. NIAGEN is a patented form of NR manufactured by ChromaDex and used under license by Life Extension. The patent covers the chloride salt form of nicotinamide riboside. This is the same NIAGEN found in True Niagen bottles. The molecule is identical. The brand name on the label is different.
Capsule: Vegetarian cellulose capsule. No gelatin. No animal-derived ingredients.
Other Ingredients: Microcrystalline cellulose (filler/binder), vegetable stearate (flow agent), silica (anti-caking agent). These are standard capsule manufacturing excipients. They are not active ingredients. They hold the powder together inside the capsule.
What Is Not in This Bottle: No magnesium stearate. No titanium dioxide. No artificial colors. No preservatives. No proprietary blends. The formula is NR, a capsule, and the minimum excipients required to form a stable capsule.

Life Extension NAD+ Cell Regenerator Pros and Cons

The trade-off is a patented NIAGEN NR ingredient at a mid-range price point against a minimalist single-ingredient formula with no added cofactors.

Pros

Patented NIAGEN NR: Same nicotinamide riboside chloride used in True Niagen. Manufactured by ChromaDex. Patent-verified ingredient identity.
300mg Per Capsule: Standard NR dose. One capsule per serving. No multi-pill dosing required.
Vegetarian Capsule: Plant-derived cellulose. No gelatin.
Minimalist Formula: NR plus capsule excipients. No proprietary blend. No unnecessary additives.
Mid-Range Price: Typically less expensive per capsule than True Niagen for the same NIAGEN ingredient.
Established Brand: Life Extension has been formulating supplements since 1980. In-house quality testing. GMP-compliant manufacturing.

Cons

Single-Ingredient Formula: No added cofactors. No resveratrol, no B-vitamins, no synergistic compounds. Some competitors add these.
Not the Cheapest NR: Budget NR options exist at lower price points, though they typically do not use NIAGEN.
No Flavor or Powder Option: Capsules only. No loose powder for dose flexibility.
Life Extension Brand Markup: You pay a brand premium over generic NR. The premium is smaller than True Niagen’s but larger than no-name NR.

Who Life Extension NAD+ Cell Regenerator Is For

Match the bottle to your priority. Ingredient pedigree, formula complexity, and price tolerance point different buyers toward different NR supplements.

Good Fit

People who want NIAGEN NR specifically but at a lower price than True Niagen
Users who prefer a single-ingredient formula without added cofactors
Long-term supplement users who want a consistent, minimalist NR capsule
People who trust Life Extension’s brand history and quality testing
Vegetarians and vegans (cellulose capsule, no animal ingredients)
Anyone who wants one capsule per serving at 300mg NR

Not the Best Fit

People who want a multi-nutrient NR formula with resveratrol or B-vitamins (see best Thorne supplements)
Budget buyers who want the cheapest NR available regardless of patent status
People who prefer powder over capsules for dose flexibility
Anyone who wants the most premium brand name on the label (True Niagen territory)
Those seeking direct NAD+ supplements rather than NR precursors

How Life Extension NAD+ Compares to the NR Category (2026)

Each NR supplement has a different balance of ingredient pedigree, formula complexity, capsule count, and price per serving. No single bottle wins every column.

Product	Active Ingredient	Dose/Serving	Notable Strength	Main Consideration
Life Extension NAD+ Cell Regenerator	NIAGEN NR Chloride	300mg	Patented NR at mid-range price, vegetarian capsule, minimalist formula	Single ingredient, no added cofactors
True Niagen	NIAGEN NR Chloride	300mg	Brand-name NIAGEN, most recognized NR brand, direct from ChromaDex	Higher price per capsule for the same NIAGEN ingredient
Pure Encapsulations NR Longevity	NIAGEN NR + Resveratrol	300mg NR + 75mg Resveratrol	Multi-nutrient formula, clinical brand positioning, added polyphenol	Higher price, two-active formula instead of single-ingredient NR
Double Wood NAD+	Direct NAD+ (not NR)	Varies	Budget price, direct NAD+ molecule rather than NR precursor	Different molecule entirely, not NIAGEN NR, budget positioning
Nutricost NAD+	Direct NAD+ (not NR)	Varies	Lowest price point, high-dose options, widely available	Not NR, not NIAGEN, budget-focused manufacturing

The key distinction is NIAGEN versus everything else. Life Extension and True Niagen both use ChromaDex’s patented NR. The molecule is the same. The price is different. Pure Encapsulations adds resveratrol to the same NIAGEN base. Double Wood and Nutricost use direct NAD+, which is a different molecule from NR. NR is a precursor. Direct NAD+ is the molecule further downstream in the pathway. The choice is NIAGEN NR versus non-patented NR versus direct NAD+. Life Extension is the mid-priced NIAGEN option.

Life Extension NAD+ Cell Regenerator FAQ

Is Life Extension NAD+ Cell Regenerator the same ingredient as True Niagen?: Yes. Both use NIAGEN nicotinamide riboside chloride, the patented NR manufactured by ChromaDex. The NIAGEN ingredient is identical in both bottles. The difference is the brand name on the label and the price. Life Extension licenses NIAGEN from ChromaDex and sells it under the Life Extension brand, typically at a lower price per capsule than True Niagen. This is an observation about ingredient sourcing, not a claim about product equivalence in any other respect.
What is the difference between NR and direct NAD+ supplements?: Nicotinamide riboside (NR) is a precursor molecule. Direct NAD+ is the molecule further along in the same biochemical pathway. NR supplements like this Life Extension product and True Niagen provide nicotinamide riboside chloride. Direct NAD+ supplements like Double Wood NAD+ and Nutricost NAD+ provide NAD+ itself. These are different molecules. This is a label distinction, not a claim about which is more effective.
How many capsules per day does Life Extension NAD+ Cell Regenerator recommend?: One capsule per day, per the label. Each capsule provides 300mg of NIAGEN nicotinamide riboside chloride. Always follow the label instructions. Consult a qualified healthcare professional before exceeding the labeled dose.
Is Life Extension NAD+ Cell Regenerator vegetarian?: Yes. The capsule is made from vegetarian cellulose. No gelatin. No animal-derived ingredients are listed on the label.
How does Life Extension NAD+ compare to Pure Encapsulations NR Longevity?: Life Extension is a single-ingredient NR formula (NIAGEN only). Pure Encapsulations NR Longevity is a two-ingredient formula (NIAGEN NR plus resveratrol). Life Extension is typically less expensive. Pure Encapsulations adds a polyphenol cofactor. The choice depends on whether you want standalone NR or NR with an added compound. Neither is universally better. They are different formulations.
Should I consult a professional before taking this?: Yes. Consult a qualified healthcare professional before starting any new supplement, particularly if you have a pre-existing health condition, are taking medication, or are pregnant or nursing. This is general guidance, not a product-specific warning.

Final Verdict

Life Extension NAD+ Cell Regenerator is the mid-priced NIAGEN NR option from a brand with four decades of longevity supplement formulation history. 300mg of patented nicotinamide riboside chloride per vegetarian capsule. Minimalist formula. NR plus capsule excipients and nothing else. If you want NIAGEN specifically and prefer not to pay the True Niagen brand premium for the same patented ingredient, this bottle is the value play. If you want added cofactors like resveratrol, Pure Encapsulations NR Longevity adds that at a higher price. If you want the absolute lowest cost per serving and do not care about NIAGEN patent status or brand history, budget NR or direct NAD+ options exist.

This is a single-ingredient NR supplement in a vegetarian capsule. The NIAGEN ingredient is the same patented NR found in True Niagen. The difference is the brand name and the price. That is the product. Everything else is preference. Always follow the label. Consult a qualified professional about your individual circumstances.

Verdict: The Mid-Priced NIAGEN NR Option

300mg NIAGEN nicotinamide riboside chloride. Vegetarian capsule. Single-ingredient formula. Same patented NR as True Niagen at a lower price. If NIAGEN ingredient pedigree matters and price does too, Life Extension NAD+ Cell Regenerator is built for that buyer.
