I don’t know about others, but for me daily exercise for 25 minutes on treadmill helps like crazy to keep my BP in check, my glucose in check, and my heart works better. I take no supplements on regular basis. May be a vitamin pill once a week is all. But I eat lots of fruits and veggies.
I have almost always exercised...been active my whole life (62)....but...I think I have a Vitamin D3 deficiency, and must take it....course...I live in a state where sun doesn’t often shine...
That’s the key to good health, exercise and diet. However, a daily supplement from a multivitamin won’t hurt anybody.
