Frequently Asked Questions

What is whey protein isolate?

Whey protein isolate (WPI) has the highest concentration of protein and BCAAs, while having less carbs, cholesterol, and fat compared to other whey proteins. WPI is also low in lactose and easy on your digestive tract.

What is hydrolyzed whey protein isolate?

Hydrolyzed whey protein isolate (HWPI) is whey protein isolate that has been broken down into smaller chains of amino acids called peptides. Peptides are easier to digest, allowing for faster absorption into the bloodstream.

What are BCAAs?

Branched-chain amino acids (BCAAs) include leucine, isoleucine, and valine. They support muscle growth and reduce muscle fatigue.

Directions

Mix 1 scoop (30g) of Whey Protein Isolate Powder with 6 to 8 fl. oz. of cold water, milk or other beverage. For 30 seconds, stir, shake or blend until dissolved. Suggested Use: For healthy adults, consume enough protein to meet your daily protein requirements with a combination of high protein foods and protein supplements throughout the day as part of a balanced diet and exercise program.

Sucralose is horrible
Why is Optimum Nutrition still using sucralose? Recent studies show that it's carcinogenic. The company discontinued its all-natural stevia-sweetened protein line. Please bring it back.

Great taste
Simply the best tasting isolate on the market, in my opinion, which gives it the best value. Chocolate and vanilla, btw, haven't tried other flavors but you probably can't go wrong with those either.

GREAT PRODUCT = GREAT RESULTS
Finally a protein powder I fell is actually creating positive results . It mixes easily without a blender even better with a blender . Great taste some chemicals in this product I don't agree with , but all but maybe one protein powder all laced with mega tons of chemicals. It's very expensive but I got my money's worth..

Not for Me
Thought this would be a better version of their regular protein.. Upon mixing with water, this protein powder turned translucent yellow
as opposed to the normal creamy milky color from regular protein. It also generated a huge amount of foam, about 1/3 of the Helimix bottle. Taste was OK, not great. Digestion was bad for me, had stomach cramps and bloating.

I'd stick to the regular version of this. The Syntha 6 Vanilla is by far the best digesting, mixing, and tasting protein I've had so far. Beats this by a mile.
