    Synbiotic 365

    Made my heart race

    Overall Experience:

    Be careful with the B vitamins. I took this the first day and within 4 hours I was having flushing and a racing heart rate. After looking up online why I would be having this problem, I discovered that the niacin is more than double the daily recommended amount. Maybe some people could handle it, but apparently am very sensitive to niacin, WebMD said I was having a medicine emergency. This is a sign of niacin overdose. Please beware if taking this product. I will be returning for a full refund.

    Bottom Line: No, I would not recommend this to a friend
