Tru Niagen, Niagen Immune NR with Vitamins C & D + Minerals, 100 mg, 30 Vegicaps

A precision formula for year-round immune health.

Tru Niagen Immune combines 100mg of patented Niagen® with essential vitamins and minerals—each selected for its clinically studied role in immune function and antioxidant defense.

A more focused formula

We took a hard look and cut what wasn’t delivering. What’s left—and what we’ve added—is fully substantiated: selenium and copper at meaningful doses, working alongside zinc for balanced mineral support. Every ingredient now earns its place at research-aligned levels.

Why NAD+ matters for immunity

NAD+ is a key player in immune cell function but can be depleted by up to 80% when immune health is compromised.* Provides the NAD+ foundation that both branches of your immune system—innate and adaptive—depend on for optimal energy and cellular repair.

Niagen helps your cells maintain resilience against stressors that challenge immune health—so you can show up for life, even during demanding times.

Precision ingredients, maximum bioavailability

• Plant-based Vitamin D3 from algae—more efficacious than D2
• Fermentation-derived Vitamin C for high bioavailability
• Two forms of zinc (gluconate and citrate) for better absorption
• Selenium and copper for complete antioxidant and immune mineral support

Designed for daily use

This isn’t a seasonal megadose you take when something’s already wrong. Tru Niagen Immune is formulated for consistent, everyday support—and stacks seamlessly with Tru Niagen and Tru Niagen Beauty for whole-body benefits.

Made in the U.S. with globally sourced components.

How to Use

• Adults take one capsule daily with food, or as recommended by your healthcare professional. For optimal absorption, take with a meal.
• Designed to complement your daily Tru Niagen routine. Take consistently for year-round immune support.
• On more demanding days—travel, stress, or disrupted sleep—an additional capsule can provide extra support.
• For whole-body benefits, pair with Tru Niagen Beauty to support cellular health, immune function, and healthy skin, hair, and nails.

Function

• Niagen®, our patented nicotinamide riboside, is clinically shown to increase NAD+ levels. NAD+ is essential for cellular energy and repair, and can be depleted by up to 80% when immune health is compromised.*
• Niagen® is one of the most well-researched NAD+ precursors available, supported by 40+ human clinical studies and routinely used in published peer-reviewed research.
• A precision blend of immune-essential nutrients—plant-based VegD3®, fermentation-derived Vitamin C, two bioavailable forms of zinc, selenium, and copper—each selected for its clinically studied role in immune function and antioxidant defense.
• Every ingredient is included at research-aligned doses. No proprietary blends, no underdosed ingredients.

FAQ

What is NAD+ and how does it work?

NAD+ (Nicotinamide Adenine Dinucleotide) is a crucial coenzyme found in every cell of your body that powers hundreds of metabolic processes. It serves as a key player in cellular energy production, DNA repair, and cellular communication. NAD+ works by transferring electrons during cellular metabolism, enabling your cells to convert nutrients into energy and supporting essential functions that keep your body running optimally.

What is Tru Niagen Immune and how is it different from regular Tru Niagen?

Tru Niagen Immune combines NAD+ boosting with targeted immune support. It contains 100mg of Niagen® (patented nicotinamide riboside) plus immune-supporting nutrients including VegD3® vegan vitamin D3, fermented vitamin C, zinc gluconate and citrate, selenium, and copper.

Unlike other immune supplements, Tru Niagen Immune addresses the fact that NAD+ levels can be depleted by up to 80% during immune stress, which compromises cellular energy and repair. The ingredients are selected for superior bioavailability, with vegan D3 being more effective than D2, fermented vitamin C versus synthetic ascorbic acid, dual forms of zinc for better absorption, and Theracurmin® with 27x higher bioavailability than standard curcumin.

Can I take Tru Niagen Immune with other Tru Niagen products, and who should consider taking it?

Yes, Tru Niagen Immune is designed to be taken alongside regular Tru Niagen supplements (300mg or 1000mg) rather than as a replacement. We recommend maintaining your baseline 300mg daily Niagen intake for optimal NAD+ support, with Tru Niagen Immune providing additional support during immune challenges.

Take 1 capsule with food, 1-2 times daily, either regularly for ongoing support or when feeling depleted. This supplement is ideal for adults experiencing immune challenges, those seeking comprehensive immune support, anyone wanting to maintain NAD+ levels during physiological stress, and health-conscious individuals looking for research-backed immune support.

How quickly can I expect to see results from taking Tru Niagen?

Cellular NAD+ support begins immediately upon supplementation. However, the cellular health benefits of increased NAD+ levels begin immediately, even before you feel noticeable changes.

Tru Niagen begins elevating NAD+ levels within hours of taking your first dose, with significant increases observed within 2 weeks of daily supplementation. For optimal results, we recommend taking Tru Niagen consistently as part of your daily routine.

What is the difference between Tru Niagen and other NAD brands on the market?

Tru Niagen is a superior choice compared to other NAD supplements because it contains Niagen®, our patented nicotinamide riboside (NR), a more bioavailable precursor to NAD+. Niagen® NR is backed by 45+ human clinical studies, and crosses cell membranes easily and is more efficiently converted into NAD+ inside cells, effectively boosting NAD+ levels.

This enhances energy metabolism, supports cellular repair, and promotes healthy aging, making Tru Niagen a more reliable, high-quality, pure, and potent option for raising NAD+ compared to other supplements. Tru Niagen® is clinically shown to increase NAD+ levels by over 50% with 300mg daily and by up to 150% with 1000mg daily and is backed by third-party quality-testing from NSF Certified for Sport and Alkemist Labs.

Is Tru Niagen safe, and are there any side effects?

Tru Niagen has been rigorously tested for safety and is well-tolerated. Our proprietary key ingredient Niagen® has successfully completed multiple FDA safety reviews and is manufactured in cGMP-certified facilities in the USA.

Niagen is supported by 45+ clinical studies demonstrating its safety and efficacy. These human studies form the foundation of our scientific evidence. Over 75% of published peer-reviewed clinical studies on NR use Niagen® NR. Niagen is also backed by independent research, with over 90% of Niagen studies being investigator-driven and third-party funded.

In clinical studies, participants reported minimal to no side effects when taking the recommended dosage up to 2,000mg per day. Some individuals may experience mild and temporary effects that typically resolve quickly. As with any supplement, we recommend consulting with your healthcare provider before starting Tru Niagen, especially if you have existing health conditions or take medications.
