InterACTIVE Nutrition Muscle Guard Elite (BCAA+Glutamine) - Tropical Punch *Only Available in Eastern Region*

Muscle Guard Elite�

Conserves Muscle Mass and Reduces Muscle Breakdown

Muscle Guard� Benefits

Stimulates Protein Synthesis
Reduces Muscle Breakdown
Improves Both Mental & Physical Performance
Prolongs Moderate Exercise Performance in Heat

Among the most beneficial and effective supplements in any sports nutrition
program are BCAA (Branch Chain Amino Acids). These are the essential amino acids: Leucine, Isoleucine, and Valine, which make up Muscle Guard�.

Muscle Guard� Features

BCAAs, the core ingredients of Muscle Guard�, features many advantages to conserve muscle mass and to reduce muscle breakdown.
BCAA supplementation, before and after exercise, has beneficial effects for decreasing exercise-induced muscle damage and promoting muscle-protein synthasis.1
BCAAs are not only substrate for protein synthesis, but also modulate several components to the synthetic machinery and help to conserve muscle mass.2
BCAA supplementation may prevent muscle loss during chronic hypobaric hypoxia.3 Intake of BCAA during exercise can prevent or decrease the net rate of protein degradation caused by intense exercise.4
BCAA supplementation can reverse the reduction in serum glutamine concentration observed after prolonged intense exercise such as an Olympic triathlon.5
Consumption of BCAA before or during endurance exercise may improve both mental and physical performance.6

Support Studies

The result of studies suggest that an intake of BCAA has an anabolic effect on protein metabolism during the recovery period after exercise rather than during the actual exercise. 7
An experimental result indicated that ingestion of BCAA reduces the perceived exertion and mental fatigue during exercise and improves cognitive performance after the exercise. 8
The data suggests that increased BCAA availability before exercise, when initial muscle glycogen is normal, results in significantly greater plasma NH3 response during exercise than placebo administration. 9
No toxic effects of BCAA's were observed in human at a dose of 2.5 g/kg/day for 3 months or 1.25 g/kg/day for 1 year. There are no reports concerning BCAA toxicity in relation to exercise and sports.10
A variety of regimen has been studied in human clinical trial. No adverse reaction was reported with the consumption of 14, 30, 22 and 40 g / day. 11
