TRU NIAGEN is a premium NAD+ supplement designed to combat the natural decline of nicotinamide adenine dinucleotide (NAD+) as we age. This patented formula uses Nicotinamide Riboside (300mg per serving) to support the 37.2 trillion cells in your body, promoting energy production, DNA repair, and overall cellular health. It is ideal for adults aged 30 and above who want to maintain vitality and slow age-related health concerns.
The standout feature of TRU NIAGEN is its proprietary ingredient, Niagen, which is one of the most well-studied NAD+ boosters on the market. Backed by a Nobel Prize winner and over 500 scientific studies, it has achieved FDA recognition as both a New Dietary Ingredient and Generally Recognized as Safe. This ensures you get a product that is both effective and rigorously tested for purity and potency.
Design and build quality are solid: the capsules are opaque white, vegetarian, and free from gluten, nuts, caffeine, and artificial additives. Each batch is third-party tested by ISO/IEC accredited labs, giving peace of mind regarding safety. The 30-serving bottle is compact and travel-friendly, with clear dosage instructions on the label.
A potential drawback is the price, which is higher than many other NAD supplements, though the patented technology and research support may justify it. Also, while 300mg is a good starting dose, some studies suggest 1000mg daily for more pronounced anti-aging effects. Users should consult a healthcare provider to determine the best dosage based on their age and metabolic stress levels.
Overall, TRU NIAGEN is a top-tier choice for anyone serious about supporting cellular health and longevity. Its scientific backing and high safety standards make it a reliable option for those seeking to offset NAD+ decline. If you value research-backed, pure ingredients and are willing to invest a bit more, this supplement is well worth considering.
Pros
- Liposomal technology may improve bioavailability over standard supplements
- Third-party lab testing provides peace of mind regarding contaminants
- Includes resveratrol, a potent antioxidant that complements NAD+
- Simple two-capsule daily regimen fits easily into routines
- Manufactured in the USA under strict quality controls
Cons
- Preclinical findings not yet confirmed in human studies
- No customer reviews available to gauge real-world experiences

The Cata-Kor Liposomal NAD Resveratrol Supplement offers a unique blend of NAD+ precursors and resveratrol in a liposomal delivery system. It is designed for health-conscious adults looking to support cellular energy and mitochondrial function without resorting to NMN. The product comes in a 60-capsule bottle providing a 30-day supply at two capsules per day.
Its standout feature is the liposomal encapsulation, which aims to protect the nutrients from stomach acid and improve absorption. A preclinical animal study cited by the manufacturer showed that this formula preserved NAD+ levels in the liver at 9.31 times higher than regular NAD+. While promising, these results have not been replicated in human trials, so efficacy in people remains unproven.
Build quality is solid: the supplement is third-party tested for heavy metals in accredited US labs, and a Certificate of Analysis is available upon request. It is manufactured and packaged in the USA from globally sourced ingredients, which adds a layer of trust for quality-conscious buyers. The capsules are small and easy to swallow.
Potential drawbacks include the lack of customer reviews and the reliance on non-human data. The price point for a month’s supply is higher than many standard NAD supplements, though the liposomal technology and added resveratrol may justify the cost for some. Additionally, those sensitive to resveratrol should check for any interactions.
Overall, the Cata-Kor supplement is a well-formulated option for those seeking an advanced NAD+ booster with liposomal delivery. While human efficacy data is missing, its third-party testing and quality manufacturing provide reasonable confidence. It is best suited for individuals already familiar with NAD+ supplements and willing to invest in a premium product.

As a paperback, the book is lightweight and compact (6 x 0.42 x 9 inches, under half a pound). The binding is standard but durable for frequent use. The layout is text heavy, which is expected for a guide of this nature, but could benefit from more charts or summaries to enhance readability.
A potential drawback is the lack of reader feedback since there are no reviews yet, which makes it harder to gauge how well the content translates to real world application. Additionally, independently published books sometimes lack the editorial polish of major publishers, though this does not detract from the quality of the research presented.
Verdict: If you are serious about understanding NAD+ and its role in aging, this guide offers a solid, science grounded foundation. It is best suited for readers who prefer depth over quick tips. Consider it a worthwhile investment despite the absence of user reviews.

Buying Guide
Form of Supplement: NR vs Direct NAD+
NR is a precursor that your body converts into NAD+. Direct NAD+ supplements often use liposomal or other delivery systems to improve absorption. Some products combine both NR and NAD+ for a dual approach. When choosing, consider whether you prefer a proven precursor like NR or a formulation that includes NAD+ directly.
For a deeper dive into how NR compares to another popular precursor, read our NMN vs NR for men over 50 guide.
Bioavailability and Absorption
Not all NAD+ boosters are absorbed equally. Liposomal formulations, like those in the Cata-Kor and UNcena products, claim higher bioavailability. Standard capsules may still be effective, but liposomal technology can enhance delivery to cells. Look for third-party verification of absorption claims.
If you are also exploring other longevity supplements, our NMN vs Resveratrol article covers another key pairing.
Additional Ingredients for Synergy
Many NAD+ supplements include complementary compounds like resveratrol, quercetin, or fenugreek. These can support antioxidant activity and mitochondrial function. For example, the WHISPERWOOD product combines NR with resveratrol and quercetin. Consider whether you want a standalone NR supplement or a multi-ingredient formula.
Learn more about how these ingredients work together in our NMN vs Urolithin A comparison.
Manufacturing and Purity Standards
Quality matters. Look for products made in facilities that follow GMP guidelines and are third-party validated for purity and potency. The TRU NIAGEN brand, for instance, emphasizes its patented ingredient and regulatory acceptance. Always check for certificates of analysis if available.

Final Thoughts
After reviewing these products, our top recommendation depends on your priorities. For a well-researched, patented NR supplement with strong scientific backing, choose TRU NIAGEN NAD+ Supplement. If you prefer a liposomal formula with added resveratrol for enhanced absorption and antioxidant support, the Cata-Kor Liposomal NAD Resveratrol Supplement is an excellent choice. Both offer reliable ways to boost your NAD+ levels and support cellular energy.
Frequently Asked Questions
What is the difference between NR and NAD+?
NR (nicotinamide riboside) is a precursor that your body converts into NAD+. NAD+ is the active coenzyme that supports cellular energy and repair. Taking NR supplements raises NAD+ levels naturally, while direct NAD+ supplements may use different delivery methods to bypass conversion.
Which is better for anti-aging, NR or NAD+?
Both can support healthy aging by boosting NAD+ levels. NR has more clinical research behind it, but liposomal NAD+ supplements may offer higher bioavailability. The best choice depends on your body’s response and your budget. For a detailed comparison, see our NR vs NAD article.
Can I take NR and NAD+ together?
Yes, some supplements combine NR and NAD+ for a dual approach. However, most research focuses on individual precursors. Taking both may not provide additional benefits over a high-quality NR supplement alone. Always consult a healthcare provider before stacking supplements.
How much NR should I take daily?
Typical doses range from 250 mg to 1000 mg per day. Many studies use 300 mg or 500 mg as a starting point. The TRU NIAGEN product offers 300 mg per serving, while other brands provide higher amounts. Start low and adjust based on your needs and professional guidance.
