NMN / NR (NAD⁺ precursors) vs Sodium Bicarbonate
Both are used for endurance. Side by side on legal status, how you get it, how it works, in plain English, side effects to watch, don't combine it with, roughly what it costs and bottom line. No winner is named — the section under the table says why.
| NMN / NR (NAD⁺ precursors) | Sodium Bicarbonate | |
|---|---|---|
| Human evidence | ★★★☆☆ | ★★★★☆ |
| Legal status | Regulated as a supplement | Regulated as a supplement |
| How you get it | No prescription needed | No prescription needed |
| How it works | Refill cellular NAD⁺ — the fuel your sirtuins — Repair-crew enzymes that switch on longevity programs (they run on NAD+). (SIRT1) and PARP DNA-repair enzyme — A protein that speeds up one specific chemical reaction in the body. run on. Why NAD⁺ matters and how it halves with age → the NAD⁺ & sirtuins pathway. The forms differ only in how they reach NAD⁺: NR converts to NMN… | Raises blood bicarbonate, increasing the extracellular pH buffer that pulls H⁺ out of muscle — the extracellular complement to beta-alanine's intracellular buffering. |
| In plain English | Age drains NAD⁺; these refill it. Which form? NR — cleanest legal status, most human data. NMN — the most-hyped, newer, a US legal grey area. Niacin (B3) — cheapest, but flushes. NAD⁺ drip — fastest and priciest, least evidence per dollar… | Baking soda makes your blood better at soaking up the acid your muscles dump during hard effort, so you last longer. The catch is it can wreck your gut. |
| Side effects to watch | NMN is a US legal grey area (FDA drug-exclusion ruling); NR is the clean supplement. No prescription drug is involved — but skip NAD⁺ IVs from unlicensed providers. | GI upset is common — trial in training first. |
| Don't combine it with | Not written up yet | GI distress is the main limiter — split the dose, take with a carb meal, or use enteric-coated capsules. High sodium load: caution if hypertensive. |
| Roughly what it costs | ~S$40–90/month for NMN; NR is pricier. Widely sold online and in pharmacies — look for third-party testing, as purity varies widely. | Almost free — plain baking soda. Capsules cost more for convenience. |
| Bottom line | The most exciting longevity lever right now; NR the cleaner legal status, NMN the newer trials, niacin the best value. Full mechanism lives on the NAD⁺ pathway. | Real ergogenic for repeated sprints; stomach tolerance is the limiter. |
#Which is better for endurance?
I do not publish an indication-specific evidence grade for NMN / NR (NAD⁺ precursors) or Sodium Bicarbonate for endurance, so I am not going to name a winner. The star ratings in the table above are whole-compound summaries across everything each has been studied for — they are not a grade for this use, and ranking them here would be misleading. Decide on the rows instead. For this pair the table above compares them on legal status, how you get it, how it works, in plain English, side effects to watch, don't combine it with, roughly what it costs and bottom line — read down it and stop at the first row where the difference matters to you. That is your answer, and it is one only you can give.
