The Secret Weapon for Athletes: How B12, Glutathione and NAD+ Boost Performance and Recovery

Boost Performance

Whether you’re training for a sporting event (like Hyrox, the London Marathon or Bodybuilding Comps), lifting heavy in the gym, or just pushing your limits week after week, your body needs more than protein shakes and rest days to perform at its best.

If you’re serious about strength, speed, stamina – and bouncing back faster – it’s time to look at three powerhouse nutrients making waves in the world of sports and fitness recovery: Vitamin B12, Glutathione, and NAD+.

At our functional health clinics across Devon, Cornwall, and Somerset, we offer targeted vitamin and micronutrient support designed to optimise your body at a cellular level – giving you the edge in both training and recovery.

Why Athletes Need More Than the Basics

Intense physical training increases your body’s demand for nutrients that support energy, tissue repair, and detoxification. Without adequate levels, you may experience:

  • M

    Persistent fatigue or lack of stamina

  • M

    Poor muscle recovery or delayed-onset soreness

  • M

    Low immunity and frequent illness

  • M

    Brain fog or poor focus during training

  • M

    Hormonal imbalances or disrupted sleep

Even a clean diet can fall short when your body’s demands are high. That’s where targeted micronutrient therapy comes in.

Vitamin B12: The Energy and Recovery Essential

Vitamin B12 plays a crucial role in energy production, red blood cell formation, and neurological function. For athletes, this means better oxygen delivery to muscles, faster recovery times, and enhanced mental clarity.

Low B12 can result in tiredness, weakness, numbness, poor endurance, and even dizziness during or after workouts.

Our Vitamin B12 boosts bypass the gut, delivering a potent dose straight into your bloodstream – ideal for those with absorption issues or high physical demands. Many clients report feeling more energised and mentally sharp within days.

Glutathione: Your Ultimate Recovery Antioxidant

Glutathione is your body’s most powerful antioxidant, responsible for detoxifying the liver, reducing oxidative stress, and aiding muscle recovery.

During intense workouts, your body produces free radicals that can lead to inflammation and cellular damage. Glutathione works to neutralise this, protecting your muscles, joints, and immune system.

Athletes using Glutathione boosts often report:

Less post-workout soreness

Faster recovery

Fewer injuries or niggles

Clearer skin and brighter eyes (a bonus side effect!)

It’s especially popular with endurance athletes and anyone training hard multiple times per week. I personally take this micronutrient and its changed the game for me, I’ve never looked or felt better.

NAD+: Cellular Energy and Longevity for Active Bodies

NAD+ (Nicotinamide Adenine Dinucleotide) is involved in hundreds of cellular processes, especially those linked to energy, DNA repair, and mitochondrial function – basically, the powerhouses of your cells.

Boosting NAD+ levels supports:

Increased cellular energy

Reduced fatigue and brain fog

Improved endurance

Faster tissue repair

Enhanced metabolism and longevity

As we age – or push our bodies harder – NAD+ levels naturally decline. That’s why NAD+ boosts are becoming increasingly popular with athletes and biohackers looking to maintain performance and recovery into their 30s, 40s and beyond.
