Which health supplements should you take and when?

We look into the most popular dietary top-ups to keep you ahead of the game…

TO TAKE WITH YOUR BREAKFAST... Studies of the herb gotu kola – the key ingredient in Foundation The Geek Molecule, £28.99 for 240ml – show it improves brain function and memory by energizing the central nervous system. Dosage: Take on 5ml teaspoon every morning to energise your mind for the day.

MORNING, NOON AND NIGHT... Perricone MD Omega 3, £75 for 270 capsules, is full of the fatty acid that has been shown to increase grey matter, brain volume, encourage tissue development and keep depression at bay. Dosage: They’re a little expensive but they are top quality, which is vital for omegas. Dr Perricone suggests three a day with food.

WHEN YOU GET TO YOUR DESK... Just like your body, the brain performs more efficiently with an abundant supply of antioxidants. Neal’s Yard Remedies Organic Greens Complex, £20 for 100g, contains active greens and sea vegetables such as spirulina, green tea and chlorella, which help to eliminate toxins. Dosage: Mix one teaspoon of powder into a juice, smoothie or even a glass of water.

BEFORE YOUR BIG MEETING Ginkgo biloba increases attention and enhances memory quality, with benefits peaking around two and a half hours after intake – so bear this in mind if you have a stressful meeting. The herb is in Swanson Brain Essentials, £28.95 for 60 capsules. Dosage: Take one or two capsules with a snack and water before a stressful event.

AFTER AN ANXIOUS DAY Magnesium is a vital mineral but is particularly good at starving off anxiety – and we’re often deficient in it. Studies show that a hit of magnesium can calm anxiety and even treat depression. Dosage: Apply four sprays of LifeFlo Pure Magnesium Oil, £16, directly to your skin. The effects are five times faster than taking it orally.
