Discount Supplements: Optimum Nutrition Gold Standard Whey Protein Review

Optimum Nutrition Gold Standard 100% Whey Protein rightly deserves its crown as the king of protein powders. For taste, quality, mixability and protein content, this product certainly ranks up there with the best of the best protein powders on the market.

Best Quality Whey Protein

When Optimum Nutrition visited us at our warehouse, they told us truthfully that they will never ever stray from the principles behind the formula in Gold Standard Whey which is to ensure that at all times the protein percentage is around 80% protein and that it includes a high degree of superior quality whey isolate and whey hydrolysates. Whey isolates and hydrolysates have a higher biological value than bog standard whey protein. Combine this with the fact that Gold Standard Whey is lower in fats and sugars than most other brands' whey proteins and you can appreciate why this protein is the world's best selling protein powder on the market.

Easier to Digest and Better Quality

People sometimes joke about how certain proteins make them pass wind. Generally this is accepted by those looking to reap the benefits of having a high protein diet. But with the added lactase and digezymes found in optimum nutrition whey, there is no need to suffer from flatulence or bloating from this protein powder. Gold Standard Whey's use higher whey isolates and hydrolysates. This makes their blend of whey protein naturally lower in fats, sugars and lactose.

Optimum Whey Wins The Taste Test

Gold Standard Whey is available in 900g, 2.25kg, and 4.53kg sizes, and comes with a huge range of flavour options like their caramel frappe, chocolate peanut butter, and double chocolate, to name just a few of our favourites. As a high-quality whey protein Gold Standard Whey has a silky texture and mixes very easily with water and whenever we have taste tested their flavours they invariably get great reviews from people who appreciate the fact that it is neither overly sweet nor does it have an artificial taste synonymous with poor quality proteins.
