Whey protein

A convenient way to add protein. Tubs vary a lot in how much protein you actually get per scoop.

What to look for

• Grams of protein per scoop, not scoop size
• A third-party testing seal
• Price per 25 g of protein, so big and small tubs compare fairly

Supplements aren't FDA-approved before they're sold, and quality varies. Talk to a doctor before starting anything new.
