Compare Supps is a UK-based vitamin and supplement comparison site that brings products from established retailers together in one place. Its search and comparison service helps shoppers discover products, compare options and find competitive prices, with the aim of making it easier to avoid overpaying. The site is free to use, and it earns a small commission when customers make purchases through listed sellers.

Its catalogue covers protein products such as whey, casein and plant-based protein; pre-workouts and performance supplements, including creatine and BCAAs; and weight-management products such as fat burners, keto support and meal replacements. Customers can also browse vitamins and health products, including multivitamins, fish oil, greens, joint support and other supplements. The site features beauty and personal-care products, clothing and accessories, and offers supplement advice on topics such as protein, amino acids, pre-workout and weight management. Compare Supps is designed for both people new to supplements and experienced shoppers seeking better prices, with product categories and goal-based browsing intended to make a broad market easier to navigate.
