Energy support formula
Quantity: 60 capsules

NAD+ is a precision energy formula featuring nicotinamide riboside (NR) and betaine to optimise mitochondrial function and cellular power — particularly in endurance athletes over 40 years of age. 

Best for:

  • Increasing energy, combatting persistent fatigue in athletes over 40 years of age
  • Sustaining energy output 
  • Accelerating muscle repair 
  • Reducing oxidative stress

NAD+

£24.99 £12.99

NAD+ is designed for endurance athletes who want to maximise cellular energy production. The primary active ingredient, nicotinamide riboside (NR), is a direct precursor to NAD+. 

This essential coenzyme plays a central role in converting nutrients into ATP — the primary molecule that powers muscle contractions and critical cellular functions. Because natural levels decline with time, this supplementation becomes especially crucial for athletes over the age of 40.

By increasing NAD+ levels, it also supports sirtuin activity — specialised enzymes that help regulate cellular stress responses, DNA repair, and mitochondrial health

To amplify these effects, the formula includes betaine, which increases mitochondrial respiration and ATP production. Betaine further supports performance by aiding in cell hydration and protein synthesis.

By supporting these processes, NAD+ helps cells maintain energy output, resist fatigue, and recover faster — even when the body is under stress. While the mechanisms are complex, NAD+ supplementation offers a practical, science-backed way to support the energy systems that drive elite performance.

  • Boosts cellular energy
  • Maintains NAD+ levels
  • Enhances mitochondrial function
  • Supports protein synthesis and muscle repair
  • Improves metabolic health
  • Reduces tiredness and fatigue
  • Promotes hydration at the cellular level
  • Contributes to the normal functioning of the nervous system
  • Maintenance of normal muscle function
  • Simple dosing with a single daily capsule 

Take one capsule daily, in the morning.

Attention! When taking supplements that contain B3 alongside NAD+, particularly B complex vitamins with higher dosages, you should monitor your total daily intake

Q: How does NAD+ differ from ATP Booster? 

A: While ATP Booster provides the "fuel" itself, NAD+ supports the "machinery" that creates that fuel. NAD+ focuses on long-term mitochondrial health and metabolic efficiency, whereas ATP Booster is more focused on supporting immediate energy availability during high-intensity efforts.

Q: How soon will I feel the effects? 

A: NAD+ is not a stimulant and does not immediately increase energy. Its benefits are cumulative and support energy systems over time. Most athletes notice improved recovery and consistent energy levels after `2 to 4 weeks of daily use. Some  sensitive individuals may notice subtle improvements in energy efficiency or recovery after 1 week.

Q: Why is betaine included in the formula? 

A: Betaine acts as a methyl donor to support the metabolic pathways that NR uses to create NAD+. It also helps maintain cellular hydration and supports protein synthesis, making it a powerful partner for NR in an endurance context.

Q: Can I take this before a race for an energy boost? 

A: For best results, NAD+ should be taken consistently every morning. While it can improve race-day performance by ensuring your energy systems are optimised, a single dose immediately before a race is unlikely to provide any noticeable benefits.

Q: Are there any side effects? 

A: Nicotinamide riboside and betaine are generally well-tolerated. Some individuals may experience an upset stomach. If you experience this, take it with solid food or discontinue use. If you have any underlying medical conditions, consult with a healthcare professional before beginning use.

Q: Can I take NAD+ with B vitamins? 

A: Yes. Nicotinamide riboside is a form of Vitamin B3, but it can be taken alongside a standard B-complex or multivitamin. NAD+ focuses specifically on mitochondrial support and energy pathways, while a B-complex provides a broader range of vitamins for general health. However, when taking supplements that contain B3 alongside NAD+, particularly B complex vitamins with higher dosages, you should monitor your total daily intake.

Q: Will NAD+ make my skin feel tingly? 

A: No. High doses of a specific form of B3 (nicotinic acid) can cause vasodilation, which can make the skin feel tingly, flushed, or prickly. NAD+ uses nicotinamide riboside (NR), a specific form of B3 that effectively raises NAD+ levels without causing this side effect.

Q: Will NAD+ make me feel “stimulated” or wired? 

A: No. Unlike caffeine or other stimulants, NAD+ does not directly act on the central nervous system. It increases energy

I stack it with regular multivitamin, rosavin and omega 3. Maybe it has a small effect on me hard to tell, I will finish this har though 🤗
