Vitamin B2 and vitamin B6 can be eaten together. Vitamin B2, called riboflavin, is a substance that maintains metabolic balance in the body and is very important. Lack of vitamin B2 can lead to keratitis, dermatitis, inflammation of the tongue, seborrheic dermatitis, conjunctivitis, keratitis, etc. Vitamin B6 is a coenzyme of many enzymes in the body, which mainly plays the role of nourishing nerve endings, improving blood supply and improving peripheral circulation. Vitamin B2 and vitamin B6 can be taken together, and the best bioavailability is to take them together between meals, which can be taken after lunch and before dinner, that is, between 3-5pm in the afternoon, to achieve the best absorption effect. Patients with poor gastric mucosal function or previous peptic ulcers can take them after lunch or 30 minutes after dinner to minimize the stimulation of the drug on the gastrointestinal tract.
