Buying Guide: What to Look For
Choose whey isolate if you want maximum protein per calorie and are not lactose sensitive. Whey concentrate is cheaper but has more carbs and fat. Plant-based blends should combine at least two protein sources for a complete amino acid profile. Check the protein-per-serving ratio and ignore marketing claims about proprietary blends.
Frequently Asked Questions
How much protein powder should I have per day?
Most people benefit from 1-2 scoops per day alongside whole food protein sources. Aim for 1.6-2.2g of total protein per kg of body weight if training regularly.
Is whey or plant protein better?
Whey has a superior amino acid profile and faster absorption, but modern plant blends are very close when combining pea and rice protein. Choose based on dietary preference.
When is the best time to drink a protein shake?
Within 1-2 hours post-workout is ideal, but total daily protein intake matters far more than timing. A shake any time you need to hit your target is perfectly fine.
