IS CLASSIC IRON BLEND A GOOD BUY?

Floradix, £11.99 for 250ml, boots.com CLAIM: Invented in 1916, Floradix contains iron, B vitamins and vitamin C for fatigue.

EXPERT VERDICT: ‘This is just the common form of iron [ferrous gluconate] added to juices,’ says Aidan Goggins.

‘The usual absorption of ferrous gluconate in the body is only around 10 per cent, but adding vitamin C can increase this percentage as it bonds to iron particles, which helps them to dissolve more completely in the gut.

‘However, we know that for any meaningful improvement we need at least 7mg of vitamin C for every 1mg iron. This may not have enough vitamin C to cut it.

‘Better iron and vitamin C combinations are available.’
