Q. When should I take Whey Protein Isolate?

A. It depends upon your lifestyle and goals, we recommend the following optimal serving times:
Immediately upon waking / 30 minutes pre workout / immediately after your workout / before you go to bed. Any other time during the day when you require additional protein intake.

Q.Does Whey Protein Isolate taste the same as Whey Protein Concentrate?

A. The taste is similar. However, as whey protein isolate is lower in fat and carbohydrates in comparison to whey protein concentrate, it is understandably less creamy. So for those who like a "lighter" shake and are calorie counting , Whey Protein 90 is the perfect choice.

Q. How much protein should I take?

A. It is recommended that you consume between 2-5 servings per day, dependant upon your own personal needs. A serving would be classed as 25g of Whey Protein Isolate. It is recommended that you take 1g of protein per pound of body weight, so adjust your intake accordingly.

Q. Is all Whey Protein Isolate the same, regardless of which brand it is?

A. The quality of protein can vary significantly and therefore the protein content will do too. In addition, just because a product may be called Whey Protein Isolate it doesn't mean that it only contains whey protein isolate. We recommend you read the ingredients and nutritionals on the label to better understand exactly what you are buying. We can assure you that our Whey Protein Isolate is purely whey protein isolate.

Q. How can I tell if the protein I use is good quality protein?

A. Keys signs to look for are the level of protein declared on the label. Look for whey protein isolate with a minimum of 90%. Unflavoured, pure whey protein isolate should be smooth with a neutral dairy taste. It should be easy to mix and with little froth. Of course the ultimate way to know is from the results you get from taking the product.

Q. Does your flavoured whey protein powder contain artificial flavouring and colouring?

A. Most protein supplements on the market today are made using artificial flavours and colours. We are committed to maintaining purity in all our products which is why we only use all natural flavouring and colouring with absolutely nothing to hide. Not only is this kinder to your body, but it also gives a more natural and real taste to your shake.

Q. Is whey protein suitable for vegetarians and vegans ?

A. Whey Protein Isolate is suitable for vegetarians, but not for vegans.

Q. Can I take Whey Protein Isolate with other supplements?

A. The simple answer is yes. We recommend you always check serving instructions on each product if you plan on taking a combination of supplements. Whey protein isolate is most commonly taken with creatine, BCAA and glutamine. In fact the uptake of protein can be improved by introducing high GI carbohydrates, as this creates an insulin spike which helps flood nutrients to the muscles quickly.

Q. Can I take too much protein?

A. If you don't burn the excess calories that come with the additional protein, it may lead to increased body fat. No other side effects have been noted in research carried out.
