Can vitamin B1 and vitamin B2 be taken together?

Generally speaking, vitamin B1 and vitamin B2 can be taken together. Both are water-soluble vitamins and play different yet complementary physiological roles in the human body. Taking them together does not result in adverse interactions. Detailed explanations are as follows:

Vitamin B1 participates in glucose metabolism and helps maintain normal functions of the nervous system, heart, and digestive system. Vitamin B2 contributes to cell growth and metabolism, participates in biological oxidation and energy metabolism, and helps maintain the health of skin and mucous membranes. Working together, these two vitamins better promote human metabolism. For example, during energy conversion, vitamin B1 is involved in carbohydrate breakdown, while vitamin B2 assists in energy release within the respiratory chain, collaboratively ensuring cellular energy supply.

Moreover, water-soluble vitamins do not accumulate significantly in the human body; excess amounts are typically excreted through urine even if slightly over-consumed. However, it should be noted that additional supplementation is usually unnecessary when daily diets are balanced. If supplementation is needed, it should be taken under a doctor's guidance to avoid excessive intake.
