We have been taking a lot of D3 for a couple of years now and a few mos ago added daily magnesium. I think we are going to add daily potassium also.
No need to boost potassium, it is in everything! Forget the banana, a medium tomato or potato has more potassium and also avocados, beans. It is in veggies, fruit, chicken, beef, pork ...and NUTS of course. Hmmm... if you live on plain white rice you might want to boost your potassium.
