What is Tru Niagen Immune and who is it for?
Tru Niagen Immune is a daily capsule containing nicotinamide riboside (Niagen®) — a NAD+ precursor — alongside vitamin C, cholecalciferol (D3), zinc as gluconate and citrate, and selenomethionine. The product supports energy levels, helps convert food into energy, supports body tissue repair and regeneration, supports healthy immune system function, and provides antioxidant activity to help reduce free radical damage to body cells.
It is formulated for adults who want a single daily capsule that combines a NAD+ precursor with these additional nutrients. Each ingredient is declared at a specific amount with no proprietary blending.
Fairfield Nutrition Thoughts
Tru Niagen Immune is one of only a few products that combine a NAD+ precursor with additional nutrients in a single capsule — nicotinamide riboside (Niagen®) at 100 mg alongside vitamin C, cholecalciferol, zinc (as gluconate and citrate), and selenomethionine, all at declared amounts with no proprietary blending. Niagen® is manufactured in cGMP-certified facilities in the USA and is third-party tested by Alkemist Labs for quality, identity and potency. For someone who wants a lower NR dose combined with these four nutrients in one capsule rather than managing them separately, this is a straightforward, transparent formulation worth considering.
Why This Formulation / How It Works
Each capsule contains five active ingredients at declared amounts: nicotinamide riboside (Niagen®) 100 mg, ascorbic acid 180 mg, cholecalciferol (D3) 350 IU, zinc as gluconate and citrate totalling 15 mg, and selenomethionine 90 mcg. There is no proprietary blend — every ingredient and its amount is stated on the label. Zinc appears as two salts: zinc gluconate and zinc citrate. Selenium is present as selenomethionine, an organic form of selenium that occurs naturally in food. Cholecalciferol is the D3 form of vitamin D.
Niagen® is a patented form of nicotinamide riboside, a NAD+ precursor. “NAD+ precursor” describes what the molecule is — its chemical class and relationship to NAD+ — in the same way that “a form of vitamin B3” does.
Taken together, this product supports healthy immune system function, maintains energy levels, helps convert food into energy, supports body tissue repair and regeneration, and helps reduce free radical damage to body cells.
When to Consider This
This formulation makes sense if you’re:
- An adult looking for a single daily capsule that provides a NAD+ precursor alongside vitamin C, D3, zinc and selenium.
- Someone who wants each ingredient declared at a specific amount rather than within a proprietary blend.
- An adult whose dietary intake of these nutrients may be inadequate and who prefers to address several in one product.
⚠️ Not suitable for: Children under 12 years old, women who are pregnant or breastfeeding. People taking medications or with pre-existing health conditions should consult a healthcare professional before use. Do not exceed the recommended daily dose of selenium from dietary supplements (150 mcg per day for adults).

Common Questions
What is nicotinamide riboside and what does Niagen® mean?
Nicotinamide riboside is a NAD+ precursor — a molecule in the vitamin B3 family. Niagen® is the patented, trademarked form of nicotinamide riboside used in this product, manufactured in cGMP-certified facilities in the USA.
Why does this contain two forms of zinc?
The product contains zinc as both gluconate and citrate, two zinc salts. Together they provide 15 mg of elemental zinc per capsule.
Can I take more than one capsule a day?
The recommended dose is one capsule daily for adults. Do not exceed the recommended daily dose of selenium from dietary supplements — 150 mcg per day for adults. One capsule provides 90 mcg selenium, so the remaining 60 mcg daily allowance should be considered if you are taking other supplements containing selenium.
Is this product suitable for vegetarians?
The capsule shell is hypromellose, which is plant-derived. The product does not contain any animal-derived active ingredients. Check with the manufacturer if you require formal vegetarian or vegan certification.
