Gold Standard Protein is one of the most affordable protein powders on the market. They often sell this protein in bulk with 80 servings making each scoop well under $1. If price is your biggest concern when picking a protein, this might be your best bet.

As far as the ingredients go, their list isn’t too long and is pretty standard. They use a blend of proteins with their main source being whey isolate, which is a plus.

Gold Standard also uses sucralose which is a common artificial sweetener and a couple of gums to help with thickening and mixing (Cellulose Gum and Xantham Gum).

Protein 21g
Serving Size: 2 Scoops (51g)

For the plant-based diets out there, Orgain makes a great protein powder. With tons of organic ingredients, this protein powder is non-GMO, gluten-free, soy-free, vegan friendly, and is certified USDA organic.

This particular protein blend has a long list of ingredients. Most come from the “50 superfoods blend” with a ton of organic fruits, vegetables, and other healthy ingredients.

Although the sugar content is low (1g of sugar), they still use stevia and erythritol to add some sweetness to the protein.

Bottom Line
