Maximize your gains with whey protein isolate from SupplementSource.ca. We offer a wide selection of top-rated whey products that deliver amazing benefits to athletes, fitness enthusiasts, and anyone looking to improve their health and wellness.

What is Whey Protein Isolate?

Whey Protein Isolate is a type of protein powder made from whey, which is a by-product of cheese-making. It’s further processed to remove lactose (a sugar) and fat, resulting in a highly concentrated protein powder that contains the nine essential amino acids. This additional processing also means that whey protein isolate contains less carbs.

High quality whey protein supplements are a great addition to your supplement stack as it supports your immune system and your metabolism. Protein is a fundamental component of every cell in your body, and while exercise supports muscle growth, you need protein after (and sometimes before) working out to help your muscles repair and stimulate the growth of lean muscle mass.

Benefits of Whey Protein Isolate

Whey Protein Isolate is a valuable component in your fitness regime. It contains all the amino acids needed to be a complete protein source but most importantly, it’s a good source of glutamine, cysteine, and leucine; the amino acids that repair muscles, reduce damage to muscle tissue and improve endurance.

Whey Protein Isolate, when compared to other forms of protein, contains less carbs, is more digestible and is quickly absorbed. A great feature of Whey Isolate Protein is that it is available in many delicious flavours which helps to curb cravings.

Who Should Take Whey Protein Isolate

Whey Protein Isolate is a valuable addition to athletes and non-athletes alike. In addition to supporting muscle growth and repair, it can also balance cholesterol levels and enhances the body’s natural antioxidant defences. There’s also research supporting Whey Protein Isolate’s ability to lower blood pressure, moderate blood sugar, reduce inflammation, and support weight loss.
