I am referring to the low priced stuff at the grocery/drug stores, the kind that is always on sale. When I buy on Swanson’s site, I try to buy the name brands.
Be sure to get the type that is most absorbable. Like, magnesium comes in various forms, but magnesium malate is by far one of the best.
I have to trust that the product suggested must work for others, otherwise he would not have me use it. However I still wish it was more “natural”, like from plant sources as does Schulze’s SuperFood and kelp. (Plants get minerals from rocks, humans get minerals from plants, right?)
