About Bio-Synergy

Bio-Synergy is a London sports nutrition brand founded in 1997 by Daniel Herman. Its first products were a protein shake and a creatine powder, and the range has grown to cover whey and plant proteins, creatine, electrolyte tablets, collagen powders and vitamins, sold under the Bio-Synergy, Active Woman, Activeman and Super 7 names.

The website lets you shop by category, by sport, from rugby and running to Hyrox and yoga, or by brand. Prices are in pounds, for example Whey Hey whey protein at £39.99 for 908g and Electro-Lite effervescent tablets at £9.99 for 20 servings. It also sells a DNA testing kit at £249. The company says many of its products are made in the UK and it is a certified B Corp.

Delivery is free on UK orders over £49, and the site aims for 3 to 5 working days in the UK and 7 to 14 days abroad. There is a Subscribe and Save option for regular orders and a points-based Loyalty Club. Speak to your GP or pharmacist if you have any concerns about your health.
