Best Magnesium Supplements Rated and Tested

You might have heard of magnesium before, but are you aware of all of this mineral’s amazing benefits? Many people don’t realize how important this mineral is to the human body, as well as the great benefits it can provide, so we decided to create a guide to help explain all of the needs and uses for this mineral, as well as the best brands for magnesium!

Magnesium is a vital mineral to the human body, but sadly it is one if the minerals most adults end up being deficient in. It is best to enrich your diet with magnesium rich foods, but this is not always easy for everyone. Instead, to ensure you are getting enough magnesium, you can take a supplement! These daily supplements will provide you with plenty of magnesium that your body needs, and as you will learn they will also provide you with many other amazing benefits associated with magnesium.

Magnesium occurs naturally in the body and is involved in tons of natural functions that the body performs every day. Without it, you may notice certain symptoms such as muscle aches or trouble sleeping. A prolonged deficiency can cause problems that are much worse and is something you want to avoid at all costs.

Unfortunately, there are many reasons why adults tend to lack sufficient amounts of magnesium, largely due to either not getting enough of it in their diet, or issues internally that cause it to not be absorbed in the body. Because this issue is so common, taking a magnesium supplement is something that everyone should at least consider.

Beyond all of the reasons your body naturally needs magnesium, there are also additional benefits you will notice from taking it as a supplement. It is known to improve energy, help you sleep better, aid in digestion, lessen muscle aches, improve heart health, prevent migraines, and help with disorders like depression and anxiety. The combination of these benefits, along with the potential symptoms you could experience from a lack of magnesium should be great motivation to start introducing magnesium into your rotation of supplements, next to your other vitamins.

There are numerous types of magnesium supplements on the market today, and all will vary based on how many milligrams of magnesium is in each pill, as well as the actual type of supplement. There are 5 main forms you can find magnesium supplements in

  • magnesium chelate
  • magnesium citrate
  • magnesium chloride
  • magnesium glycinate
  • magnesium threonate

Each type has a slightly different absorbability and may have other factors associated with them. For example, magnesium citrate can help people specifically looking for help with their digestion, and magnesium chloride often comes in the form of an oil that is rubbed on the skin and can help people who can’t properly absorb it through food or supplements.
