As you may already know, One Fit Stop is more than an Online Supplements Store in Australia (Although we’re pretty awesome at it!). It will soon be the largest online platform for social and professional interaction amongst fitness users. But right now, We’d like to talk supplements with you.
To simplify your fitness, we’ve provided you with some important information regarding 4 key ingredients of many workout supplements: Whey Protein Isolate, Creatine, L-Glutamine and Branched Chain Amino Acids.
#1 Whey Protein Isolate (WPI)
What is it? WPI is a dietary supplement created when filtering milk protein. Whey proteins are highly bioavailable, quickly absorbed into the body, and have a high concentration of branched chain amino acids, which are used to fuel working muscles and stimulate protein synthesis.
WPI has a higher percentage of pure protein than other forms of whey protein and is usually around 90% protein. WPI can be filtered enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free.
Any Evidence? A 2010 study published in the Journal of International Society of Sports Nutrition, found that whey protein isolate (WPI) supplementation has been used effectively to increase muscle size and strength after resistance training, with some of these improvements thought to come from improved recovery from exercise sessions.
What is it? Creatine is a non-essential amino acid that is an important source of chemical energy for muscle contraction. Dietary sources include meat, fish, and other animal products, but creatine may also be formed in the liver, kidney and pancreas from the amino acids glycine, arginine and methionine.
Once creatine reaches the muscles, it’s converted into phosphocreatine (creatine phosphate), and ultimately becomes the body’s primary energy source—adenosine triphosphate (ATP). Muscle concentrations of creatine are lower in older and middle-aged adults and may explain why they respond so noticeably to creatine.
Any Evidence? According to the Journal of the International Society of Sports Nutrition (JISSN), Creatine is the most effective performance enhancing nutritional supplement currently available for increasing high-intensity exercise capacity and lean body mass during training.
What is it? L-Glutamine is a free form amino acid that is the single most abundant amino acid in muscle tissue required for synthesis and protection.
L- Glutamine plays a role in the health of the immune system, digestive tract, and muscle cells, as well as other bodily functions. It appears to serve as a fuel for the cells that line the intestines. Heavy exercise, infection, surgery, and trauma can deplete the body's glutamine reserves, particularly in muscle cells.
Any Evidence? L- Glutamine has been shown to be highly effective and supplements have been used as a treatment for various conditions, including preventing infections that often follow endurance exercise, reducing symptoms of overtraining syndrome, improving nutrition in critical illness, alleviating allergies, and treating digestive problems.

#4 Branched Chain Amino Acids
What is it? Branched-chain amino acids (BCAAs) are the building blocks of proteins and are essential amino acids that can be oxidized in skeletal muscle. The 3 branched-chain amino acids (BCAAs) leucine, isoleucine, and valine are among the nine essential amino acids for humans and account for around 35% of the essential amino acids in muscle proteins and around 40% of the preformed amino acids required by mammals.
Any Evidence? A 2004 study on the effects of BCAA supplementation found that BCAA requirement is increased by exercise. Furthermore, BCAA supplementation before and after exercise was found to have beneﬁcial effects for decreasing exercise-induced muscle damage and promoting muscle-protein synthesis; this was found to suggest that BCAAs are an effective supplement in relation to exercise and sports.
