Product Information

100% PROTEIN ISOLATE MATRIX

SYNTHA-6® ISOLATE^® is an ultra-premium protein powder consisting of a 50/50 blend of Whey Protein Isolate and Milk Protein Isolate. Our unique ISOLAST protein matrix combines the advantages of both fast and slow digesting protein sources that have had much of the fat, sugar and other undesirable components ‘isolated’ out, making SYNTHA-6® ISOLATE the ideal post-workout recovery shake. SYNTHA-6® ISOLATE provides 25 grams of high-quality protein and the same delicious taste as SYNTHA-6®, thanks to our exclusive flavor technology.

The Benefits of Supplemental Protein

Daily adequate protein intake is important for muscle maintenance and development. Protein is needed to help repair muscle broken down during exercise and build new muscle. Using a quality protein powder will help supplement the daily amount of protein required by your body and help you to reap the benefits from every training session. Supplementing with protein before and/or after training can also have a noticeable impact on your recovery and performance.

25 grams of protein per scoop
11 grams of essential amino acids (EAAs) per serving

I have used many protein shake mixes and without a doubt the BSN Syntha-6 Isolate is my favorite. I was worried that the reduction in carbs and calories would reduce the quality of the flavor and all around texture, but that is not the case here. Yes, the non-isolate Syntha 6 is creamier and has more flavor but if your looking to reduce carbs and calories, the Isolate is definitely a great less filling option.*

Strawberry is great, look forward to every scoop- chocolate tastes granular and heavy. Don’t even feel like they’re from the same company. I have no idea what went so wrong - taste so different that if I had purchased it from Amazon I’d say it’s a knock-off*
