Tru Niagen vs Elysium Basis: Which NAD+ Supplement Wins?

The NAD+ supplement market has produced two standout products: Tru Niagen from ChromaDex and Basis from Elysium Health. Both are built around nicotinamide riboside (NR) — one of the best-studied NAD+ precursors available. Both have human clinical evidence showing they raise NAD+ levels. And both command premium prices in a market full of questionable products.

So which one is actually worth your money?

The comparison is closer than you'd expect, but there are real differences in formula design, certification, and long-term safety data that should inform your decision.

Quick Verdict

Tru Niagen is the better buy for most people. It delivers more NR per dollar, carries NSF Certified for Sport status (meaningful for athletes and anyone wanting rigorous third-party verification), and keeps the formula simple — pure NR without additional ingredients whose long-term safety profiles are still being worked out.

Elysium Basis has a compelling angle: it pairs 250mg NR with 50mg pterostilbene, a polyphenol related to resveratrol that activates sirtuins. The scientific advisory board reads like a longevity hall of fame. But pterostilbene is a double-edged sword — some research shows it raises LDL cholesterol, and at $60/month, you're paying for a combination whose synergy is plausible but not definitively proven.

If you're an athlete in tested sports, want maximum third-party accountability, or want straightforward NR without add-ons, go with Tru Niagen. If you want the pterostilbene synergy and trust Elysium's research pedigree, Basis is worth considering.

Side-by-Side Comparison

The Key Differences

1. Tru Niagen Is Pure NR; Basis Adds Pterostilbene

This is the defining difference.

Tru Niagen is exactly what it says: NIAGEN-brand nicotinamide riboside, 300mg per serving, nothing else of note. ChromaDex developed NR as an NAD+ precursor and has published more research on it than any other company. Their NIAGEN ingredient has been used in the vast majority of peer-reviewed NR studies.

Elysium Basis adds 50mg pterostilbene to 250mg NR. Pterostilbene is a naturally occurring analog of resveratrol found in blueberries. It activates SIRT1 (a sirtuin, part of the NAD-dependent enzyme family), and Elysium's hypothesis is that combining an NAD+ precursor with a sirtuin activator creates a synergistic longevity effect.

The theory is scientifically coherent. The evidence that this particular combination produces meaningfully better outcomes than NR alone is still limited.

2. The Pterostilbene Question

Here's the thing they don't put on the front of the bottle: pterostilbene may raise LDL cholesterol.

A randomized controlled trial published in the Journal of Alternative and Complementary Medicine (Riche et al., 2013) found that 250mg/day pterostilbene increased LDL cholesterol by approximately 0.14 mmol/L, with a larger effect in a combined pterostilbene + resveratrol group. The 50mg in Elysium Basis is one-fifth that dose, so the effect is likely minimal — but "likely minimal" isn't the same as "definitely zero."

For people with existing cardiovascular concerns, elevated LDL, or on lipid-lowering medication, this is worth discussing with a doctor. For healthy people without those risk factors, 50mg is probably fine. But it's a variable that pure NR (Tru Niagen) doesn't introduce.

3. NSF Certification Matters More Than People Think

Tru Niagen carries NSF Certified for Sport status. This isn't just a label — it means every production batch is tested for over 270 substances banned by sports organizations, and that what's on the label is actually in the capsule at the stated amount.

Elysium Basis is third-party tested, but not NSF Certified for Sport. For most people, this distinction doesn't matter much. For competitive athletes in tested sports, it matters significantly. For anyone wanting the highest possible standard of independent verification, NSF > generic third-party testing.

4. Clinical Evidence

Both have human clinical evidence that NR raises NAD+ levels in blood. That's well-established.

ChromaDex's research pipeline has produced multiple published trials on NIAGEN specifically, including a landmark 2018 study by Martens et al. showing that 300mg and 1,000mg/day both significantly raised whole-blood NAD+ levels in healthy adults. Multiple other trials have used NIAGEN as the NR source.

Elysium conducted a human trial published in npj Aging and Mechanisms of Disease (Dellinger et al., 2017) showing that Basis raised blood NAD+ levels by an average of 40% in adults over 60. This is legitimate, peer-reviewed evidence. One trial is less than many trials, but it's real data.

The practical takeaway: both products demonstrably raise NAD+ levels. The downstream effects of elevated NAD+ on human longevity outcomes remain an active area of research.

5. The Elysium Science Advisory Board

Elysium's founding story is worth knowing: the company was co-founded with a scientific advisory board that includes multiple Nobel laureates. Their chief scientist Lenny Guarente is one of the world's leading researchers on sirtuins and longevity. This isn't marketing window-dressing — it's real scientific credibility.

Does the advisory board make the product better? Not directly. But it does suggest the formulation decisions were made with serious scientific input, which is more than most supplement brands can claim.

Who Should Buy Tru Niagen

Tru Niagen is the better choice if you're:

• An athlete in tested sports — NSF Certified for Sport is the standard for competitive athletes
• Focused on pure NR without additional variables — no pterostilbene, no LDL considerations, nothing extra
• Price-sensitive — more NR per dollar, especially at single-purchase pricing
• Wanting the most extensively studied NR ingredient — ChromaDex's NIAGEN has been used in more published trials than any other NR source
• Starting NR supplementation for the first time — simpler formula is easier to troubleshoot if anything comes up

Who Should Buy Elysium Basis

Elysium Basis is the better choice if you're:

• Interested in sirtuin pathway optimization and believe the pterostilbene synergy adds meaningful value
• A cardiovascular healthy individual who doesn't have concerns about modest LDL effects
• Drawn to the research pedigree — if Elysium's scientific advisory board and founding team is meaningful to you
• Already using other sirtuin-pathway supplements (resveratrol, etc.) and want to consolidate with Basis
• Comfortable paying a small premium for the combination formula

The Bottom Line

For the majority of people starting a NAD+ protocol, Tru Niagen is the right call. More NR per dollar. NSF certified. The most studied NR ingredient in the world. No extra variables. The formula is simple precisely because simplicity is correct here.

That said, Elysium Basis is not a bad product. The pterostilbene addition is scientifically motivated, not marketing fluff. If you're deeply engaged in longevity optimization and want the full Elysium formula, it's a reasonable choice — just go in with eyes open about the pterostilbene consideration.

The one thing both products agree on: you're better off with a quality NR supplement than no NAD+ support at all. The research on NR's ability to raise NAD+ levels is consistent and replicated. Whether you choose Tru Niagen or Elysium Basis, you're getting the real thing.

Frequently Asked Questions

How long does it take to see results from NR supplements?

Blood NAD+ levels increase measurably within 2–4 weeks at doses of 300mg/day. Most people don't "feel" this directly — NAD+ isn't stimulant-like in its effects. The benefits are downstream: improved cellular energy, mitochondrial function, and longevity pathways that operate quietly. If you're expecting a noticeable energy burst, you may be disappointed. If you're thinking long-term, the data is genuinely interesting.

Is pterostilbene in Elysium Basis dangerous?

At 50mg/day, the evidence suggests it's safe for most healthy adults. The LDL-raising concern comes from higher-dose studies (250mg+). That said, if you have existing cardiovascular conditions, elevated LDL, or are on statins or other lipid medications, discuss it with your doctor before adding Basis to your routine.

Can I take both Tru Niagen and Elysium Basis?

You could, but there's no logical reason to. Both are NR supplements — you'd just be doubling your NR intake and spending more money. If you want 600mg/day of NR (a higher dose protocol some researchers use), simply take two capsules of Tru Niagen.

What's the right dose of NR?

Most clinical trials have used 250–300mg/day and shown significant NAD+ increases. Some trials have used up to 1,000mg/day for more pronounced effects. The 300mg dose in Tru Niagen is supported by solid evidence. There's no established "optimal" dose yet — the science is still developing.

Is there a better third option?

If you want pure NR at a lower price point, Alive by Science and Double Wood Supplements both offer NR supplements at competitive prices. If you're open to NMN (nicotinamide mononucleotide) instead — a different NAD+ precursor that's been generating significant research attention — brands like ProHealth, Wonderfeel, and Renue By Science offer solid options. NR vs NMN is its own debate worth reading about before committing.
