I get bruised really easily and don t know why. I had gastric bypass surgery 3 yrs ago so I take B12 sublime all, B Complex, Calcium tablets, Biotin for thin hair, Bariatric One a day vitamins, vitamin D3, baby aspirin, Probiotic and Premarin (so my hubby want divorce me). If I hit my arm or legs I get a red bruise. My skin is so dry this winter. Am I overdosing on vitamins, etc?
