❌ The fuss around these two products at the minute are crazy.... and rightly so. ❌
A wee bit of a read but well worth it for anyone looking into the Healthy Aging process and Cellular support 💪
WHY CYCLE NMN OR NR AT ALL?
NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are NAD⁺ precursors — molecules your body converts into NAD⁺, a coenzyme central to cellular energy production, DNA repair, and sirtuin activation.
Both have attracted significant research interest over the past decade, with human clinical trials now demonstrating measurable increases in blood NAD⁺ levels following supplementation.[1,2]
One of the most common questions we hear from Feel Supreme customers is: should I take NMN or NR continuously, or cycle on and off?
The honest answer is that no large-scale, long-duration human trial has yet compared continuous versus cycled dosing head-to-head. What follows is a synthesis of current research, expert practitioner protocols, and the rationale behind cycling strategies — designed to help you make an informed decision alongside your healthcare professional.
❌ THE CASE FOR CYCLING ❌
Several researchers and longevity clinicians — including those in the field of NAD⁺ biology — advocate cycling rather than continuous use, for three main reasons:
Receptor sensitivity: Continuous high-dose supplementation may reduce the body's sensitivity to NAD⁺-dependent pathways over time, analogous to how some hormetic stressors (cold, fasting) lose effectiveness without periodic breaks.
Mimicking natural fluctuation: NAD⁺ levels naturally rise and fall with circadian rhythm and metabolic demand. Cycling may better replicate this physiological pattern.
Precautionary principle: While current evidence suggests NMN and NR are well-tolerated, long-term continuous supplementation data in humans is still limited. Cycling provides a built-in monitoring window.
That said, some researchers argue that for individuals with significantly depleted NAD⁺ — common from middle age onwards — continuous supplementation may be preferable until levels are restored. This is another reason a personalised approach, ideally guided by NAD⁺ blood testing, is valuable.
✅ PROTOCOL 1 — 5 DAYS ON / 2 DAYS OFF (BEGINNER-FRIENDLY)
Take your NMN or NR supplement Monday through Friday and rest on weekends. This is the lowest-friction option: it aligns with a working-week rhythm, makes missed doses easy to track, and provides two rest days per week without long enough gaps to lose momentum.
Suitable for: First-time users, those wanting a simple routine, individuals who prefer caution.
Typical dose: 250–500 mg NMN or 250–300 mg NR daily on active days.
Duration: Run indefinitely, reviewing every 3 months.
✅ PROTOCOL 2 — 8 WEEKS ON / 2 WEEKS OFF (CLASSIC CYCLING)
Supplement continuously for 8 weeks, then take a complete 2-week break. This is one of the most widely discussed cycling windows in practitioner circles, giving the body a meaningful rest period while maintaining a predominantly supplemented state across the year.
Suitable for: Intermediate users with an established tolerance, those tracking biomarkers.
Typical dose: 500 mg NMN or 300 mg NR daily.
Duration: Repeat the 10-week block; reassess after 3–4 cycles.
✅ PROTOCOL 3 — 3 MONTHS ON / 1 MONTH OFF (QUARTERLY RESET)
A longer on-phase favoured by those who find benefit builds gradually. The 1-month off period allows for a meaningful washout and a subjective reassessment of how you feel without supplementation — a useful baseline reset.
Suitable for: Experienced users, biohackers tracking NAD⁺ blood levels, or those using higher doses (750–1000 mg NMN).
Typical dose: 500–1000 mg NMN or 300–600 mg NR daily on active days.
Duration: Review annually with a healthcare professional.
