What people come to us for when they are running on empty - B vitamins, iron, CoQ10 and the herbal tonics. Several B vitamins and iron contribute to the reduction of tiredness and fatigue, which is why they sit at the centre of this range.

Solgar, Viridian, Lamberts, HealthAid and Bio-Strath cover most of it. B vitamins, iron and CoQ10 have their own categories if you already know what you want.

Bio-Strath is the outlier here and worth knowing about - a Swiss herbal yeast tonic that has been made the same way since the 1960s, and one of the few things in this category people come back for by name rather than by ingredient.

Solgar have been going since 1947, Viridian build without fillers or binders, and Lamberts supply the practitioner market. Biocare formulate in the UK alongside practitioners.

Persistent tiredness is worth a blood test before it is worth a supplement. Iron and B12 are the two that most often turn out to be genuinely low, and both are simple for a GP to check - guessing at iron is a bad idea, since too much causes its own problems.

If your diet is short rather than your bloods, a B-complex is the sensible starting point: it covers the group rather than betting on one.

B12 comes almost entirely from animal foods, so vegans and many vegetarians need a reliable source. Absorption also falls with age and with some medications, which is why higher-dose and sublingual forms exist.

Liquid and spray versions suit anyone who struggles with tablets or absorbs poorly. The form is on the pack - methylcobalamin and cyanocobalamin are both widely used.

FAQ

Which B vitamin is for energy?

Several contribute to the reduction of tiredness and fatigue - B2, B3, B5, B6, B12 and folate among them. A B-complex covers the group, which is usually more sensible than picking one.

Should I take iron if I am tired?

Get a blood test first. Iron is a common cause of tiredness but too much iron causes its own problems, and your GP can settle it quickly.

Do B vitamins make urine bright yellow?

Yes - riboflavin (B2) is naturally fluorescent yellow and what you do not absorb is passed out. It is entirely harmless and not a sign of waste.

When should I take them?

Morning suits most people, and with food is gentler on the stomach. Some find B vitamins keep them awake if taken late in the day.
