What I recommend

People often ask me which supplements to buy and which tracker to wear on their wrist. Here are my answers, and how I choose.

How I choose

It's not the nutrient, it's the carrier.

When I choose a supplement, I look less at the nutrient and more at what surrounds it: excipients, colourings, sweeteners, preservatives, the quality of the capsule, how the pack has been stored. That's where brands really differ.

Turn the pack over and read the ingredients. If there's a string of E numbers besides the active ingredient, put it back on the shelf.

Try it yourself

Read the label like I do.

The same supplement, vitamin D3, in two versions. Switch between them and see what else is in there apart from the vitamin.

Tap the highlighted lines and I'll tell you what they're for.

One line of vitamin and seven of additives, to make it, flavour it and colour it. All you needed was the first one.

Ingredients

  • Vitamin D3 (cholecalciferol)

Where do you live?

Two brands, and no others. If a supplement has been recommended to you for a specific clinical reason, stick with it: don't swap it for one of these.

  • Solgar

    Solgar supplements

    Vitamins, minerals and other supplements, made since 1947.

    I use them myself, and I'm 100% behind them. Short labels, no pointless additives, and an amber glass bottle that protects the contents from light.

    Where to find it · Elsewhere

    In many countries: you'll find your local distributor on the international site, solgar.com.

    solgar.com
  • Diamond Life

    Diamond Life supplements

    Supplements from an Italian brand based in Parma.

    I recommend it for the same reason as Solgar: short labels, with no additives you don't need.

    Where to find it · Elsewhere

    The official website only ships to Italy and San Marino. Outside Italy, I recommend Solgar.
