Premier Protein Vanilla Shake vs Oikos Chocolate Protein Shake

Both shakes deliver 30g of protein with 1g of sugar, so the choice comes down to format and extras. Premier Protein is the better buy for most people: a 12-pack of 11 oz shakes, 24 vitamins and minerals, gluten-free and kosher, and a 4.6 rating across nearly 29,000 reviews. Oikos adds 5g of prebiotic fiber and 720mg calcium per 12 oz bottle and uses no artificial sweeteners, but it comes in a 4-pack and only in chocolate. Pick Oikos if digestive support and a bigger bottle matter more than variety.

• Choose the Premier Protein if you want a larger multipack, vanilla flavor, added vitamins and minerals, and a long track record of high ratings.
• Choose the Oikos if you want prebiotic fiber, more calcium per bottle, no artificial sweeteners, and a larger 12 oz serving.
