Supplements guide

A clear overview of the main protein-related supplement types and the buying differences worth paying attention to.

Protein powders

Protein powders remain the broadest category. Whey is popular for everyday use, casein is often chosen for slower digestion, and plant-based blends suit buyers avoiding dairy. The useful comparison points are serving profile, ingredient style, flavour range and overall fit for the goal you have in mind.

Protein bars and snacks

Bars trade some purity for convenience. The stronger options can still be useful, but the category varies a lot, so it helps to look beyond the wrapper and check the protein, fibre, sugar and overall calorie profile.

Creatine and workout add-ons

Creatine is one of the best-known add-ons in the sports supplement market. Pre-workout powders, amino blends and similar products sit in a different lane from standard protein, so they are best compared with a clear idea of what role they are meant to play.

Meal replacement shakes

These are typically built to be more filling and rounded than a standard protein powder. They often include carbohydrates, fats, fibre and added vitamins, which makes them a different proposition from a lean post-workout shake.
