I started taking a magnesium blend and my heart issues disappeared. I am healthy, don’t smoke, drink very very moderately and exercise regularly.

Interesting. I don't have any experience with heart issues, and have not really studied the subject, so I won't comment on the OP's issue.

However ...

Regarding magnesium, I will throw this out --

I was interested in figuring out why a lot of people get gray or white hair, even at a young age. So, I looked into it.

I found some interesting info, though I have not had time to dig any deeper to verify.

The concept is this: gray or white hair is actually bleached from the inside.

A person can create a lot of hydrogen peroxide within their body, and that can bleach the hair from the inside.

Why does the body create the hydrogen peroxide? Because they have a magnesium deficiency.

Magnesium blocks the creation of hydrogen peroxide.

So, why do they have a magnesium deficiency?

Two reasons: (1) they don't eat enough food that has BIOAVAILABLE magnesium, and (2) they do eat foods that block the absorption of magnesium.

What foods are high in bioavailable magnesium? Not a lot. Most foods don't have a lot, but maybe that's because we don't need a lot -- at least, most people.

Animal foods have bioavailable magnesium; most plant foods that have magnesium (such as bananas) have it in a form that is not so bioavailable. So, while you get some, you don't get as much as you would think because the body cannot do anything with most of it.

ALL plants have anti-nutrients that block the absorption of minerals. Plants don't want to die, so they create chemicals to harm animals that try to eat them, causing disruption to the animal's digestive tract.

Phytic acid is one of these anti-nutrients., and it blocks the absorption of magnesium.

Legumes (beans), seeds, nuts, and grains are all high in phytic acid.

Bottom line: If Bill Gates is pushing it, it is probably bad for you.

Supposedly, magnesium is also important in heart health. I would think that doing it as naturally as possible would be ideal for most people, but supplementation might be beneficial to anyone who has a known issue.
