What is the best supplement for tiredness?
It depends on the cause, so a GP blood test comes first if you are tired all the time. Nine nutrients carry the authorised claim, and eight are in VH Life. Vitamin C contributes to the reduction of tiredness and fatigue, and riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid and magnesium carry the same claim. The ninth is iron, which VH Life does not contain.
What does the NHS say?
The NHS lists poor sleep, an unhealthy lifestyle, stress and hormonal changes as common causes, and conditions such as iron deficiency anaemia, diabetes and an overactive thyroid as possible ones. It says to see a GP if you have felt tired for a few weeks and are not sure why. Source: NHS: Tiredness and fatigue.

| Pantothenic acid, 12mg, 200% NRV | Pantothenic acid contributes to the reduction of tiredness and fatigue |
| Riboflavin, 1.4mg, 100% NRV | Riboflavin contributes to the reduction of tiredness and fatigue |

Where does VH Life fit?
VH Life is a UK-made food supplement: one 11.8g berry sachet a day in cold water, with 87 active ingredients including 26 vitamins and minerals with declared amounts. It carries the claims above because it provides those nutrients at qualifying levels; it makes no claim beyond them. On subscription VH Life is £49.99 for 28 sachets every 4 weeks, which works out at £1.79 a day. There is also a 7-day trial (7 sachets, £12.99, one per customer) and one box of 14 sachets for £34.99, with free UK delivery. See the full label or the ingredients index.
If you take any medicine, ask your GP or pharmacist first. If you take warfarin, ask your anticoagulant clinic first: the sachet contains vitamin K, cranberry, co-enzyme Q10, ginkgo, turmeric and ginseng.

How long before I notice a difference?
