Two Ingredients, No Flavors, No Markup on Marketing

If you’re not interested in flavor variety and just want a straightforward protein source, BulkSupplements’ Whey Protein Isolate strips things down to the essentials: whey protein isolate and sunflower lecithin, nothing else. No added sugar or sweeteners, and it’s sold unflavored so it’s easy to fold into shakes, smoothies, oatmeal, or baking without changing the taste of whatever you’re mixing it into.

It’s manufactured in a cGMP-compliant facility, and because it’s sold by weight rather than flavored servings, it tends to work out to a lower cost per gram of protein than most name-brand tubs. Each serving is about 30g (4 tbsp) mixed into 8-12oz of water.

Who It’s For

A smart choice for anyone who doesn’t care about flavor variety and wants the lowest cost per gram of protein — bakers who add protein powder to recipes, people who blend it into smoothies, or anyone who just wants a functional unflavored protein source.
