Why does this supplement contain 100mg of vitamin B2 when the recommended intake is much lower?

The Nutrient Reference Value (NRV) for riboflavin is 1.4mg a day. This supplement is a high-strength formula providing 100mg of riboflavin per capsule, equivalent to more than 7,000% of the NRV in a single capsule.

Is a 100mg dose of vitamin B2 safe to take every day?

UK food supplement labelling guidance from the Department of Health and the Food Standards Agency requires a cautionary label statement for high intakes of several vitamins and minerals, including vitamin B6, vitamin A, iron and zinc. Riboflavin is not among the vitamins for which this guidance requires a cautionary statement. If you have any concerns about taking a high-strength supplement, speak to your GP or pharmacist before use.

How long does one pack of 100 capsules last?

Each pack contains 100 capsules. Taken at the recommended dose of one capsule a day, one pack provides just over three months' supply.
