Protein powder

Protein powders - The convenience supplement

Definition

Protein powders are concentrated, dehydrated protein supplements derived from various sources (milk, eggs, plants). Their main purpose: hit daily protein needs simply and quickly when food is hard.

💡 Protein powders are a tool, not a magic bullet. They can replace nothing for those who eat enough protein from food.

Common mistakes

• ❌ Replacing real food with shakes (lack of micros, fiber)
• ❌ Taking 100 g of protein in one go (max ~40 g per meal usefully absorbed)
• ❌ Buying based on packaging, not ingredients
• ❌ Thinking that "more = better" (excess protein doesn't help)
• ❌ Neglecting other macros (carbs, fats, fiber)
