Can vitamins B12 and B2 really help with weight loss

Vitamin B1 and B2 cannot directly aid in weight loss, but moderate supplementation may help improve metabolic function. Vitamin B1 and B2 are water-soluble vitamins that mainly function by participating in energy metabolism and promoting the breakdown of sugars and fats. Vitamin B1, also known as thiamine, is a key coenzyme in carbohydrate metabolism. Deficiency may lead to carbohydrate metabolism disorders, but excessive intake does not accelerate fat consumption. Vitamin B2, also known as riboflavin, participates in redox reactions and has a certain auxiliary effect on fat metabolism, but simple supplementation cannot achieve the effect of reducing fat. Both cannot directly decompose body fat or inhibit fat synthesis, and their metabolic effects can only be reflected on the basis of a reasonable diet and exercise. When some people suffer from vitamin B deficiency due to long-term dieting or gastrointestinal absorption disorders, their metabolic rate may decrease. Supplementing with vitamins B1 and B2 under the guidance of a doctor can help restore basal metabolic levels, but it requires calorie control to produce weight loss effects. Some weight loss products add vitamin B components mainly to promote metabolism, rather than directly reducing fat. Maintaining a balanced diet is the best way to obtain vitamins B1 and B2, as whole grains, lean meat, dairy products, and other foods are rich in these two nutrients. Weight loss should be achieved through scientific control of calorie intake and increased exercise expenditure, and it is not recommended to rely solely on nutrient supplementation. If there are symptoms of vitamin deficiency, it is recommended to seek medical examination and adjust the dietary structure or supplement dosage under professional guidance to avoid potential side effects caused by self consumption of large doses.
