We evaluated the effects of vitamin B complex supplements on chest pain and heart health by reviewing 15 studies involving over 71,000 participants.
Our investigation revealed that while there were no significant differences in rates of heart attacks, overall deaths, or serious side effects between those receiving vitamin B complex and placebo, there was a slight reduction in stroke incidence.
However, the benefits were minimal and outcomes varied with dosages, indicating that more research is needed to draw firm conclusions about the effectiveness of these vitamin interventions on cardiovascular events.

Solgar is a trusted brand for vitamins and minerals. I took the B-complex for severe palpitations. After three weeks, the palpitations lessened, which I'm pleased about, especially when combined with magnesium.
