B vitamins are amongst the most widely utilised vitamins processed by the human body. From the release of energy in food to maintaining skin, hair and nail health it is not hard to see why our body uses so much of it. This Vitamin B-100 Complex from Lamberts is extremely potent and is recommended for those with serious vitamin B deficiencies, usually for a 2 month period (after which it is advised to switch to the lower strength B-50 Complex). Lamberts Vitamin B-100 Complex is now available from Pharmacy First. It is not recommended for use in pregnant or lactating women.
