Vitamins and supplements: the everyday shelf

This is the one shelf on the site that is not an accessory, and it is the one where we are most careful about what we say. These are food and pharmacy-shelf products: electrolytes, protein powders, fibre, vitamins, minerals and a few kitchen items that go with them. We describe what each one is and what people commonly use it for. We make no claim about what any of them does.

The shelf sorts into a few honest groups. Hydration: electrolyte sachets and tablets, oral rehydration salts in the World Health Organization ratio, and a time-marked bottle. Protein: whey isolate, clear whey, casein, plant protein, bone broth protein, ready-to-drink cartons and bars, with a shaker, a blender and a kitchen scale beside them. Digestion: psyllium and prebiotic fibre powders, digestive enzymes, a probiotic, and ginger in both chew and capsule form. Then the ordinary vitamin and mineral aisle — D3 with K2, a B complex, B12, B6, C, zinc, iron, calcium with D3, potassium, a multivitamin — and a handful of the single-ingredient powders people ask for by name: creatine, collagen, glycine, taurine, carnitine, EAAs, HMB.

Two things are worth knowing before you buy any of it. First, the form on the label is usually the difference between two listings of the same thing: magnesium glycinate rather than oxide, ubiquinol rather than ubiquinone, iron bisglycinate rather than sulphate, B6 as P-5-P. Second, servings per tub, not the tub's price, is what makes one cheaper than another. If you take any medicine, ask a pharmacist before adding a supplement — several of the items here interact with common prescriptions, and a pharmacist will tell you in thirty seconds.

What differs between listings

  • Form. How it arrives: something to swallow, something to stir into a drink, something to eat, or the kit that goes with them rather than a supplement itself.
  • The form of the active ingredient, which is what most listings of the same product actually differ by.
  • Servings per container, and whether an unflavoured version exists.
