GO contains two of the most common nootropics, caffeine and l-theanine, which with its other ingredients, have been shown to provide mental stimulation, anti-fatigue effects, increase reaction time and improve power.
Caffeine, often associated with coffee (pictured), is a powerful (and probably one of the best known) stimulant. Research suggests caffeine (particularly in combination with L-Theanine) offers greater visual acuity, greater muscle dexterity, significantly increased mental focus, self-reported alertness and a prolonged natural attention span.
L-Theanine is a unique form of amino acid often found in high concentrations in young green tea leaves (pictured). It's long been thought to reduce the perception of stress and improve attention. Research shows L-Theanine synergises very well with Caffeine, helping to bring a calm focus and mental alertness without the 'caffeine jitters'.
Studies suggest that Phosphatidylserine is a compound that has widespread functions in our body. They show it could be effective for improving mental focus, mood, performance, learning ability and stress, attention and hyperactivity. Soybeans (pictured) are a great vegetarian source of Phosphatidylserine.
Alpha-GPC is a high quality source of Choline. Researches shows that Choline is essential for memory function, speed of thought, mental clarity, increased attention, focus, energy, and HGH levels. Eggs (pictured) are a great natural source of Choline.
Grape Seed Extract
Several new studies are demonstrating a potent energetic improvement in muscles and performance following supplementation with grape (pictured) seed extract. Potentially, the molecular function of grape seed extract may be used to enhance energy production, exercise ability, and increase stamina.
Vitamin B6 (as Pyridoxine)
Research has shown that adequate intake of vitamins B6 is essential to ensure optimum energy production, increased physical performance and the building and repair of muscle tissue. Vitamin B6 is naturally prevalent in sunflower seeds (pictured).
Vitamin B3 (as Niacin)
Vitamin B3, also called niacin releases growth hormones. Research indicates that vitamin B3 is essential for high performance and intensive training. Nuts such as peanuts (pictured), almonds and seeds are naturally rich in vitamin B3.
