With so many supplements on the market nowadays, it's becoming more and more difficult for the consumer to know exactly what to buy. Things can get pretty confusing out there. From protein powders to weight gainers, the list goes on and on. One of the most popular supplements people look for are without doubt whey protein as many people have been told or have read that whey protein is essential for any muscle building enthusiast and that's right.

Nowadays we have several types of whey protein like whey protein concentrate and whey protein isolate. Whey protein isolate is definitely better as it has virtually no fat, cholesterol, carbohydrates and lactose. It also has the highest biological value(BV) of all proteins at 154. The biological value determines how fast a protein digests and absorbs in the muscle cells. The higher the value, the faster the digestibility and absorption rate. This is one of the reasons many bodybuilders advocate the use of a whey protein isolate shake post-workout to deliver essential amino acids fast to your starving muscle cells as after a grueling workout, your muscles are depleted and need to be replenished as soon as possible.

When looking for a whey protein isolate, consider these two important factors.

Undenatured Protein

A whey protein isolate which has been denatured has usually been heat-processed, hence it has lost some of its nutritional value. What you need is cold-processed whey protein isolate. First of all, this protein has undergone a process known as Cross-Flow Microfiltration hence the term CFM which means the protein has been ultrafiltered using a cold-processed technique and never heated. The end result is you get the purest whey protein isolate with virtually no fat, cholesterol, carbohydrates and lactose and best of all it's 99% undenatured. Hence you get a high-quality and superior whey protein isolate right there.

No Artificial Sweeteners

Some whey protein supplements contain artificial sweeteners like Aspartame, Neotame, Saccharin, Acesulfame Potassium(also known as Acesulfame K or Ace K), Sucralose(also known as splenda) and these are questionable for health. These sweeteners are many times sweeter than table sugar. If you're health-conscious, you might want to consider supplements free from artificial sweeteners, either you get a totally unflavored and unsweetened whey protein isolate or one which use natural sweeteners like Stevia. Stevia is a herbal sweetener which is extracted from the leaves of the Stevia rebaudiana plant, a South American herb and you get a 100% natural sweetener with zero calories and several health benefits as well.
