Renue By Science NMN Supplement | 200 SLC Enteric Capsules - 250mg Nicotinamide Mononucleotide per Serving | Delayed Release for Increased Absorption | Manufactured in the USA

Clinical trials typically use 250-500mg daily. Renue By Science NMN 200 SLC Enteric Capsules delivers 250mg NMN per serving (1 capsule); 200 servings per container, which we classify as Therapeutic relative to that range.

NMN is generally well tolerated with most medications. TMG (trimethylglycine) included in this formula can affect homocysteine metabolism — if you are on medications affecting methylation pathways or B12 metabolism, consult your doctor. Zinc at supplemental doses can interfere with copper absorption and antibiotics (especially quinolones and tetracyclines) — take zinc 2 hours apart from these medications. No major interactions with common cardiovascular or blood pressure medications are documented for NMN.

Human clinical trials of NMN at 250-500mg/day for up to 12 weeks show excellent safety profiles with no serious adverse events. Long-term use beyond 12 months lacks large-scale human data, though preclinical animal research spanning 1+ year is reassuring. TMG is a recognized safe methyl donor at supplement doses. The main monitored parameter for long-term NMN use is NAD+ metabolite levels and methylation status.

The enteric coating is specifically designed to minimize stomach irritation by preventing NMN from releasing in the acidic stomach environment — this should reduce the nausea that some users experience with uncoated NMN capsules. TMG can occasionally cause mild nausea or loose stools at high doses, but 250mg per serving is well within the tolerated range. Zinc may cause GI upset if taken on an empty stomach.

NMN pairs well with resveratrol (NAD+-dependent SIRT1 activation), pterostilbene, and CoQ10 for longevity stacking. TMG inclusion reduces the need to add a separate methyl donor. The zinc in this formula (typically 5-15mg range) should be factored into total daily zinc intake if you take a multivitamin. Avoid taking with other high-dose zinc supplements to prevent exceeding the UL of 40mg/day.

Take 1 capsule daily with or without food. The enteric coating means the capsule should be swallowed whole — do not crush, chew, or open the capsule as this destroys the delayed-release mechanism. Take zinc (included) with food to reduce GI upset. Morning dosing is commonly preferred to align NAD+ elevation with daytime energy needs. Start with 1 capsule daily for the first 2 weeks before considering dose escalation.

NAD+ levels in blood measurably rise within 1-2 weeks of daily NMN supplementation — this is well documented in human pharmacokinetic studies. Subjective benefits (improved energy, better sleep quality, sharper cognition) typically become noticeable at 4-8 weeks of consistent use. DNA repair and metabolic efficiency improvements operate on longer timescales of 3-6+ months. Individual variation is significant.
