GEN-TEC NUTRITION’S AMINO LEAN is a premium blend of instantised, free form amino acids with anti-oxidants; Vitamin C and Green Tea extract for individuals with a goal of supporting a positive nitrogen balance whilst reducing free radical damage. With added Chromium Pic AMINO LEAN is also ideal for maintaining a higher lean muscle mass to body fat ratio. AMINO LEAN is best consumed either before fasted cardio, during exercise or throughout the day. AMINO LEAN has been naturally flavoured and coloured to produce a tasty, refreshing beverage to be enjoyed whilst supporting your goal of a lean healthy body.

SUGGESTED USE: Mix 5g (1 tsp) in 250mL of water and consume before or during exercise or throughout the day as a healthy, tasty beverage. Store in a cool, dry, dark place.

INGREDIENTS: L-glutamine, instantised BCAA 2:1:1 (L-leucine, L-isoleucine, L-valine), glycine, flavour, L-arginine AKG, L-lysine, L-tyrosine, ascorbic acid, taurine, sweetener (sucralose), green tea extract, acidity regulator (citric acid), natural colour (carotene), chromium picolinate, silicon dioxide. Contains caffeine.

Protecting lean muscle is achieved via the use of amino acids such as branched chained amino acids. Branched chain amino acids play a critical role in stimulating protein synthesis and support a positive nitrogen balance which allows effective muscle repair and maintenance to take place (Rogero and Tirapegui, 2008). During periods of fatigue, the levels of branched chained amino acids in the muscles can drop, especially during prolonged endurance events. Consuming BCAA can mitigate the symptoms of fatigue during exercise and assist in recovery post exercise (Choi et al., 2013).

Glutamine is an amino acid which primary functions are to increase protein muscle repair and provide the cells of the immune system with energy (dos Santos et al., 2010). Athletes consume glutamine to protect and help the immune system recover from intense training and decrease the risk of upper respiratory tract infection (Sacks, 2003).

During periods of calorie restriction, mental focus can take a significant hit, especially when hard training is involved. The adverse effects from this can be overcome by supplementing tyrosine and caffeine. Tyrosine is an amino acid which manufactures neurotransmitters like dopamine, norepinephrine and epinephrine (O’Brien et al., 2007). Tyrosine is observed to increase performance on stress-sensitive attention tasks which would otherwise lead to a decline in cognitive (mental ability) capacity (Mahoney et al., 2007). During acute periods of stress there is a heightened use of tyrosine-dependent neurotransmitters which is a contributing factor to the reduction in motivation, attention and working memory, therefore consuming tyrosine can increase “brain power” under times of moderate-heavy stress (Mahoney et al., 2007). Caffeine not only combats fatigue but it aids in the release of endorphins which reduce the perception of pain during exercise (Sökmen et al., 2008). In addition, like tyrosine, it stimulates the production of neurotransmitters like dopamine and norepinephrine which improves alertness and vigilance during periods of fatigue and sleep deprivation (Goldstein et al., 2010).

In order to manage body fat levels, ‘AMINO LEAN’ has been formulated with caffeine derived from green tea extract and the Epigallocatechin gallate (EGCG) present in green tea which aids fat loss (Sinclair and Geiger, 2000). Together they can shift substrate utilisation during exercise to increase the amount of fatty acids used for energy (lipolysis) and supress the body’s use of stored glycogen for fuel. This increased mechanism of fatty acid mobilisation is ideal for athletes who aim to keep the body fat levels low without sacrificing lean muscle mass. Overall the effects of caffeine and green tea extract increase thermogenesis and mobilisation of fats which aids in the reduction body fat levels.

The addition of arginine alpha-ketoglutarate and glycine increase vasodilation of blood vessels, allowing a more fluent blood flow of nutrients to the muscle cells, thus aiding nutrient transport (Botchlett et al., 2013). Furthermore its use in combination with the above ingredients ensures that ‘AMINO LEAN’ provides an all-round approach to supporting optimal body composition.
