Real-Life Stories: Vitamin B3 in Action

Susan, a 57-year-old office worker, struggled with leg swelling and numbness after long days sitting. After adding niacin-rich foods like tuna and peanuts to her diet, she noticed less swelling and warmer feet within weeks, complementing her daily walks.
David, a 63-year-old retiree with mild peripheral artery disease, started taking a low-dose niacin supplement (under medical supervision) and eating niacin-rich meals. He reported fewer leg cramps and better stamina during exercise. These stories show how vitamin B3 can support circulation alongside lifestyle changes.
