Nicotinamide Mononucleotide (NMN) is one of the most researched longevity compounds — but figuring out how much to take can be confusing.

This guide explains what the science says, how to personalise your dose, and the difference between The Base and The Repair NMN supplements from For Youth.


TL;DR — How Much NMN to Take?

  • Start with 250 mg/day if you’re new to NMN

  • Consider 500–1000 mg/day if you’re 40+, heavier, or seeking faster results

  • Don’t exceed 1200 mg/day without medical guidance

  • The Repair – NMN+ delivers 450 mg NMN + 50 mg apigenin + 50 mg L-tryptophan — a powerful all-in-one stack for ageing, inflammation, and energy



Why We Recommend 250 mg as a Starting Dose

The Base – NMN contains 250 mg of high-purity NMN — ideal for those new to NAD+ supplementation.

  • Matches most clinical research

  • Gentle on the system

  • Budget-friendly for daily use

  • Can be scaled up easily



When to Use a Higher Dose

Clinical studies support doses of 500–1000 mg/day , especially for people who:

  • Are over 40

  • Have high levels of stress or fatigue

  • Want to reverse early signs of ageing

  • Need faster results for focus, recovery, or inflammation

No adverse effects have been reported at these levels in human studies.



Biological Age as a Dosing Indicator

If you’ve done a biological age test — like The Clock — and your cellular age is higher than your actual age, it’s a good reason to:

  • Start with at least 450 mg/day , or

  • Stack The Repair and The Base for over 700 mg/day total


The Repair – NMN+: The All-in-One Upgrade

The Repair – NMN+ contains:

  • 450 mg NMN

  • 50 mg apigenin (inflammation, mitochondrial defence)

  • 50 mg L-tryptophan (mood, serotonin, sleep support)

Ideal for:

  • Users over 40

  • Those managing stress, fatigue, or inflammation

  • Longevity seekers who want more than just NAD+

FAQ

Q: Can I take more than one NMN product?
Yes. Many stack The Base + The Repair to increase dosage or add anti-inflammatory and mood support.

Q: Is it safe to take 900–1000 mg/day?
Yes — studies show no major adverse effects at this level, but consult your doctor if you go above.

Q: Should I take NMN with food?
Not required. Some take it on an empty stomach; others prefer with food for GI comfort.

Q: How soon will I feel the effects?
Most feel a difference in 2–6 weeks , with full benefits building over 2–3 months.



Final Thoughts

There’s no universal dose — only the one that works best for your body, goals, and biology .

  • Start low and track how you feel

  • Use tools like biological age tests to refine your protocol

  • Choose clean, well-dosed, well-tested formulations like The Base and The Repair

Longevity is a journey. With the right dosing, NMN can be a powerful tool to walk it well.
