The sweetener used is sucralose, but there are a number of flavors using stevia, as in Steviol Glycosides. The unflavored variety has no sweetener.

Real vs Fake Whey Protein

The global health supplement market is worth billions of dollars and year, and Japan is not immune to counterfeiter protein products. My Protein is aware of this and their video explains how you can verify your purchase:

Re-sealable Plastic Bags

One of the biggest gripes about Impact Whey protein is their cheap resealable bags – which also translates into cheaper costs! These bags often don’t seal very well between usages. This means that if you buy a large bag and you don’t check the seal real carefully after using, your protein powder can easily spoil.

If you’re sold on Impact Whey for the lost cost, then the solution is get a separate tub with a screw-on lid for better air-tightness and storability.

Expiration Dates

Traditional storefronts that stock My Protein products, including Impact Whey, are safer bets in that you can easily check the expiration date before buying, and that’s what you get.

Online shopping can be a but tricky. It’s not so much that you’ll land up with a product beyond the expiration date, but rather a date that may expire before you have chance to finish the whole pack. So, make sure you how much to buy, how soon you’ll finish the pack, and check with the expiration date with the online vendor.

Top Ranking Whey Protein Powders in Japan

One common denominator is that most of the top-selling brands all use synthetic sweeteners for their flavored proteins. Only Impact Whey and X-plosion have an additive-free or unflavored option. Plain flavor usually has sweetener added.

Additive-free flavored proteins include Limitest Whey Protein (buy link) which uses stevia and a similar option is Body Wing (buy link). Alternatively, grass fed whey protein powder is generally all natural and additive free. For their top quality, they tend to be a little pricier.
