NMN is one of those supplements that’s gained a lot of attention in recent years, and for good reason. It’s a direct precursor to NAD⁺ – an essential molecule that your body relies on for energy production and cellular repair.

The problem is, NAD⁺ levels naturally decline with age, and that’s linked to reduced energy, slower recovery, and accelerated ageing.

By supplementing with NMN, you’re essentially giving your cells the raw material they need to keep NAD⁺ levels higher. That can translate into feeling more energised, recovering better, and supporting long-term health.

What I like about TBJP’s version is that they’ve used Uthever®, a pharmacy-grade raw material tested for purity and stability. A lot of NMN products cut corners, so this gives me confidence that you’re getting exactly what’s on the label.

NB: Whilst results from early human studies are promising, research on NMN in humans is still relatively new. Most trials are short-term and involve small groups. The science is moving fast, but more large-scale, long-term studies are needed to fully understand the benefits and safety profile.

Who It’s For:

• Anyone over 30 looking to support healthy ageing and energy.
• People who feel their recovery or energy levels aren’t what they used to be.
• Athletes who want to support endurance and recovery without stimulants.
• Anyone interested in longevity and cellular health.

What It Does:

• Supports NAD⁺ levels, which naturally decline with age.
• May improve energy metabolism and reduce fatigue.
• Helps cellular repair and recovery.
• Early human trials show improvements in aerobic performance and endurance.

How I’d use it:

Two capsules daily with food, ideally at the same time each day. The main thing is consistency – this isn’t about instant results, but about building long-term support.

The Science:

NMN with regards to boosting NAD⁺ Levels

Study: 12-week randomised controlled trial of 250 mg/day NMN in healthy men and women. Results showed significant increases in blood NAD⁺ by week 4.

NMN supplementation safely increased NAD⁺ levels in humans, confirming its bioavailability and potential as an anti-ageing support.

NMN and it’s role in improving physical performance

Study: Six-week randomised, placebo-controlled trial in amateur runners. NMN at 300-1200 mg/day improved ventilatory thresholds, oxygen uptake, and power at ventilatory thresholds compared with placebo.
