Caffeine in its natural form is known to improve your focus and concentration. It has also been specifically proven to boost alertness during tasks.

Studies have found that alertness and work output improved after caffeine supplementation, due to a marked improvement in vigilance and increased ability to exert sustained attention.

At physical level aspects such as endurance performance, and endurance capacity also improved.

  • Participants of the study reported better focus, higher energy levels, improved efficiency and wakefulness.
  • Various studies have also found that Caffeine can help endurance in athletes due to its ergogenic effect. Researchers have found that ingesting caffeine can increase the accumulation of muscle glycogen thereby preventing fatigue and increasing time to exhaustion.

Coconut water powder comes from the liquid of fresh coconuts, which is then freeze-dried and turned into a powdered form.

Coconut water is rich in vitamins and minerals including; potassium, magnesium, sodium and calcium.

Research suggests that this natural ingredient is the perfect alternative to traditional sports drinks due to its strong concentration of electrolytes.


  • Coconut Water contains a large amount of Potassium, Potassium is a vasoactive electrolyte that supports normal muscular and neurological function.
  • The presence of minerals like Calcium support a normal energy-yielding metabolism.
  • Coconut Water powder uses Magnesium, this mineral supports a normal electrolyte balance as well as contributing to reduced tiredness and fatigue.

Powher includes a potent blend of the Vitmain B complex including; Pantothenic acid (B5) as well as Pyridoxine (B6) and Cyanocobalamin (B12). Studies have shown that Pantothenic Acid supports:

  • Reduced tiredness and fatigue
  • A normal ‘energy yielding metabolism’
  • Normal ‘mental performance’ as well as normal ‘functioning of the nervous system’

Maintaining optimal levels of Vitamin B is crucial for healthy energy levels and effective physical performance.

Enxtra combines 3 natuaral extracts including C.Flexuous oil (LG) as well as water soluble extracts of A. galanga and G. Glabra.

These all combine to create one of most premium pre-workout ingredients on the market, as a result you won’t find in the vast majority of supplements on the market.

EnXtra has been designed as a natural ‘Caffeine Amplifier’, the aim is to enhance and compliment the effects of caffeine.

The result is a pre workout that supports reduced tiredness and fatigue during exercise, but without the post-workout ‘crash effect’! The ‘Caffeine crash’ is the word coined for side effects such as ‘Palpitations, jitters, headaches and insomnia’.

Vitamin B6 is a water-soluble ingredient that is well known for its ability to maintain healthy nerve and metabolic function.

A study observing the blood vitamin levels of athletes found that concentrations of B6 fell after a marathon and that supplementing with B6 contributes to:

  • Normal functioning of the nervous system
  • Normal protein and glycogen metabolism
  • Reduction of tiredness and fatigue and the normal function of the immune system

A 2010 study showed that Vitamin B12 deficiency is more prominent in people who exercise on a regular basis.

Optimal Vitamin B levels contribute to a normal homocysteine metabolism, as well as normal red blood cell formation. Like the other B Vitamins, it plays an important role in reducing tiredness and fatigue, as well as a normal energy yielding metabolism and functioning immune system.

Oxyjun is a bespoke ingredient that is extracted from the bark of the ‘Termninalia Arjuna’ tree. It has undergone human testing and has been developed specifically for use in pre workout supplements and other similar products.

This safe, natural compound is ‘stimulant free’ and originates from India and Sri Lanka. Also known as an Ethanolic extract it has potent antioxidant properties.

Rednite is a special type of fresh beetroot that is rich in the natural ‘performance enhancer’ Nitrate. Rednite includes up to 5 times the amount of Nitrate as regular Beetroot, and as a result up to 10 times the number of antioxidants.

Rednite is a high- end, specialist ingredient that has been formulated specifically for workout products.

This aromatic amino acid is a precursor to the production of neurotransmitters like dopamine, epinephrine and nor-epinephrine. As a result it is claimed that L-Tyrosine may improve mood during acute stress conditions. More importantly there may be a causal relationship between L-Tyrosine and improved focus and concentration.

Powher includes a hefty 2g dose of pure L-Citrulline malate per daily serving. This amino acid is naturally occurring and is an extremely popular ingredient found in pre-workout powders.

Even though the body produces it naturally, L-Citrulline has been the subject of a number of studies assessing its effect on athletic performance.

Beta-Alanine is a naturally sourced, non-essential amino acid.

A review report published in 2010 considered the effects of beta-alanine supplementation on performance during multiple bouts of high-intensity exercise.

Beta-Alanine and has also been shown to increases the levels of carnosine a protein molecule. High levels of Carnosine may reduce fatigue in women during aerobic activity. Carnosine are reported to be lower in women compared to men.
