Performance - Endurance

Support stamina, recovery and aerobic capacity for endurance sport

★★★★★ Nutri Tailor 4.6/5 "Excellent" on Trustpilot
  • Greater capacity and less fatigue
  • Faster recovery between sessions
  • Sustained output for endurance sport

A three part endurance performance protocol combining energy production support, physical performance enhancement and immune protection during high volume training. Power Up (2 capsules) provides the cellular energy foundation: 200mg L taurine, 100mg acetyl L carnitine, 100mg L tyrosine, 100mg Korean panax ginseng 4:1, 67mg lion's mane 10:1, 20mg iron (as bisglycinate), activated B vitamins (B6 as P5P, B12 as methylcobalamin, folate as L methylfolate) and 1000 IU algae derived vitamin D3.

Creatine Capsules (4 capsules) provide 3g creatine monohydrate with 120mg ginkgo biloba 50:1 and 152mg bilberry for cognitive and vascular support during prolonged effort. Elderberry Immune Support addresses the well documented immunosuppression that occurs with high training volumes, providing 159mg elderberry extract (equivalent to 3g elderberries), 159mg NAC, 32mg vitamin C and 6mg zinc. Endurance athletes are significantly more susceptible to upper respiratory infections during heavy training blocks, making immune support an essential part of any endurance protocol.

Power Up

Enhances focus, concentration, energy levels and prevents adrenal fatigue

Ingredients

Sharpen focus and sustain mental energy naturally with this nootropic blend

A comprehensive energy and performance formula combining 18 active ingredients across B vitamins, minerals, amino acids, adaptogens and nootropics.

Key benefits:

  • Sharper focus and mental energy
  • Sustained concentration all day

Directions for use:

Take 2 capsules once per day away from food.

Taking on an empty stomach (mid morning works well for most people) supports absorption of the amino acids and adaptogens. If this causes nausea, take with a light snack instead. The iron in this formula is bisglycinate, the gentlest form, but sensitive individuals may still prefer to take with food.

This product is the energising component of several bundles including Energy Optimiser, Mood Boost, Performance Endurance and others. As a standalone product, it provides a comprehensive daily energy, focus and vitality formula. Avoid taking in the evening as the ginseng, tyrosine and B vitamins can be stimulating.

Creatine - Capsules

Increases energy, athletic performance and brain function. Also supports fertility.

Ingredients

Build strength, power and cognitive performance with pure creatine monohydrate

This is not a standard creatine supplement. It combines 3g of creatine monohydrate (per 4 capsule serving) with a targeted cognitive support complex: 120mg ginkgo biloba extract at a concentrated 50:1 ratio, 152mg bilberry extract, 400mcg vitamin B12 as methylcobalamin, 800mcg folate as L 5 methylfolate, and 4mg biotin. The result is a formula designed for both physical and mental performance.

Creatine monohydrate is the most researched sports supplement in existence. At 3g daily it maintains muscle creatine stores, supporting power output, recovery and lean mass. But creatine also plays a significant role in brain energy metabolism, with emerging evidence for cognitive performance under fatigue and sleep deprivation. The addition of ginkgo biloba (supporting cerebral blood flow) and bilberry (rich in anthocyanins for vascular and eye health) extends the cognitive dimension. Methylcobalamin and L 5 methylfolate are the bioactive forms of B12 and folate, bypassing the need for conversion and directly supporting methylation, nerve function and homocysteine clearance.

Key benefits:

  • More strength and explosive power
  • Sharper focus under mental fatigue
  • Most researched sports supplement

Directions for use:

Take 4 capsules once per day with breakfast.

If preferred, this can be split into 2 doses of 2 capsules taken with 2 separate meals. Consistency matters more than timing for creatine, as the benefit comes from maintaining saturated stores rather than acute dosing.

For optimal sporting and cognitive performance, dosage depends on bodyweight. Those weighing under 70kg should take 4 capsules 30 minutes before exercise. Those weighing 70kg and above should take 6 capsules 30 minutes before exercise. No loading phase is required at these doses, though it takes approximately 3 to 4 weeks of daily use to fully saturate muscle creatine stores.

Elderberry Immune Support

Improves immune resilience

Ingredients

Boost immune resilience and helps the body resist infections with concentrated elderberry extract

Elderberry Immune Support combines four evidence based immune ingredients in a single capsule: elderberry extract, N-Acetyl Cysteine (NAC), vitamin C and zinc.

Each capsule provides 159mg of elderberry extract (Sambucus nigra), equivalent to 3g of whole elderberries. Elderberry is rich in anthocyanins, the dark purple pigments that have demonstrated antiviral and immune stimulating properties in clinical research. NAC at 159mg supports glutathione production, the body's primary intracellular antioxidant, which plays a direct role in immune cell function and respiratory health. Vitamin C (32mg) and zinc (6mg) provide foundational immune support.

This formula is designed for both daily immune maintenance and as an increased dose option during acute illness. The combination of antiviral (elderberry), antioxidant (NAC, vitamin C) and immune modulating (zinc) ingredients provides broader support than any single ingredient alone.

Key benefits:

  • Stronger resistance to colds and flu
  • Rich antioxidants for immune support
  • Milder symptoms during illness
Each capsule contains: %NRV*
Vitamin C
32 mg 40%
Zinc

N Acetyl Cysteine

† Nutrient Reference Value (NRV*) not established

Directions for use:

Take 2 capsules once or twice per day with meals.

For daily immune maintenance, 2 capsules once per day provides consistent baseline support. During cold and flu season, or at the first signs of illness, increase to 2 capsules twice per day.

Taking with food improves zinc tolerance and supports overall absorption.

View Elderberry Immune Support
  • Frequent endurance training
  • Inability to lose central fat
  • Not seeing the physical benefits from high effort exercise
  • Increased frequency of injury

Take 2 Power Up capsules and 4 Creatine capsules in the morning. Take 1 Elderberry Immune Support capsule with breakfast and 1 with dinner.

Power Up is best taken mid morning or 30 to 60 minutes before training. The creatine can be taken at any time but consistency matters more than timing. The Elderberry is split across two meals to maintain immune support throughout the day.

During heavy training blocks or race preparation, the Elderberry can be increased to 2 capsules twice daily. The creatine dose of 3g daily supports endurance performance through improved phosphocreatine recovery between repeated efforts and has evidence for cognitive performance during prolonged exercise.

Lifestyle tips

How to boost your results

Be aware of the impact of alcohol

As this drastically decreases recovery after exercise. It caps it to about 10% of what we achieve when alcohol isn't present. If you are asking your body to perform at a high level it would be wise to remove or at least significantly limit alcohol consumption.

Choose your support products wisely

When doing long races many will reach for electrolyte + carb powders, gels, protein powders etc. The issue here is quality. Many products will contain sweeteners and synthetic agents that are incredibly disruptive to gut bacteria, and as endurance exercise is shown to significantly impact this vital part of our immune system already it would be wise to carefully research what you are using.

Rest

Put as much attention and focus on this as you do your training. There is absolutely no way to sustain a high level of performance without injury if the body doesn't have adequate time to recover.

Frequently asked questions

How does Performance - Endurance support energy?

Performance - Endurance supports natural energy production at the cellular level.

When should I take energy support?

Take in the morning with breakfast.

How is this different from caffeine?

These nutrients support actual energy production, not just masking fatigue.

Why am I always tired?

Chronic fatigue has many causes: nutrient deficiencies, thyroid issues, blood sugar imbalances, poor sleep, or adrenal stress.

Can I take this with coffee?

Yes, energy nutrients complement caffeine and may reduce the crash. Consider reducing caffeine as energy improves.

How long until I feel more energised?

Some notice improvements within days. Deeper energy restoration takes 4-8 weeks of addressing root causes.
