The advice is to use this only for a short period and under the supervision of a specialist.
B vitamins are naturally found in a wide range of foods such as whole grains, meat, fish, eggs, dairy, pulses, nuts and green leafy vegetables.
Yes, 100 mg of vitamin B6 per day is considered a very high dose. Use a high dose of B6 under the supervision of a professional. Use for a maximum of several consecutive weeks, unless otherwise advised. Stop taking if tingling or a burning sensation occurs.
Niacinamide and nicotinic acid are both forms of niacin (vitamin B3), but differ in their chemical structure. Nicotinic acid can cause temporary redness or a warm feeling of the skin in some people, a reaction known as a 'flush'. Niacinamide, the form used in this product, usually does not cause this reaction.
DFE stands for Dietary Folate Equivalents, a unit mainly used in the US to express the amount of folate and folic acid in a product in a comparable way.
B vitamins, especially riboflavin (vitamin B2), often give urine a bright yellow colour. This is a well-known and harmless feature of riboflavin in high doses.
