Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Thiamin (vitamin B1) has scientific support for its role in heart health, though the strength of evidence is moderate and primarily focused on deficiency states. Thiamin is an essential cofactor in carbohydrate metabolism and is vital for proper function of the cardiovascular system. Deficiency in thiamin can lead to a condition called wet beriberi, which is characterized by heart failure, edema, and other cardiovascular symptoms. Clinical studies have shown that thiamin supplementation can improve cardiac function, particularly in patients with heart failure who are often found to have lower blood thiamin levels—possibly due to increased urinary loss or poor dietary intake. Small clinical trials have reported improvements in left ventricular ejection fraction and symptoms in heart failure patients after thiamin supplementation. However, robust evidence for thiamin supplementation in individuals without deficiency or in the general population for primary prevention of heart disease is lacking. Thiamin is not generally considered a treatment for heart disease outside deficiency states, but its critical metabolic role and the documented cardiovascular impact of deficiency support its relevance to heart health. In summary, scientific evidence justifies the use of thiamin for supporting the heart, especially in deficiency or in certain heart failure patients, but routine supplementation for cardiovascular health in the absence of deficiency is not well established.
