15 Best Magnesium Supplements of 2024

Magnesium is one of the seven essential minerals we cannot live without. Magnesium is also a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation (NIH).

An essential dietary mineral, it is a required mineral co-factor in over 300 enzymes in the body. Since over 68% of Americans are magnesium deficient, this would be a good mineral to start consuming.

Magnesium is also a component necessary for the activation of vitamin D, and without sufficient amounts of it, your body cannot properly utilize the vitamin D you’re taking.

Magnesium Citrate vs Magnesium Oxide for Constipation

Both magnesium citrate and oxide are useful as laxatives. However, According to University of Maryland Medical Center, magnesium citrate is better absorbed in the body which may them work more effectively.

However, both types of magnesium should be used with caution. It's not a good idea to use it as a laxative if you have nausea, vomiting, or stomach pain. 

Because people with IBS frequently feel gastrointestinal pain, magnesium should be used with caution and only after consulting with a doctor.

Magnesium citrate is also an “antidote” to oxalate that can be helpful if you’re struggling with oxalate toxicity or just happened to eat a high-oxalate meal. Magnesium citrate should be taken with meals. This way absorption of any oxalate in the meal will be impaired. (R)

E. Magnesium Citrate Supplement – Treat Occasional Constipation on a Short-Term Basis

This product was recommended by my ND to help with my constipation. I figured out the dose I need with a little trial and error and take every night before bed. I have been regular every day (it really does feel like a Christmas miracle compared to how I was before). Another doctor had me on addictive laxatives, but these are much better and non addictive.

Benefits of Magnesium

Magnesium is a mineral that plays a role in a number of vital biological functions. It is involved in muscle and neuron function, blood pressure and blood sugar regulation, and even bone and DNA formation.

Magnesium may help you sleep better. It aids in the activation of mechanisms that quiet and relax you, and it plays a key part in your nervous system. It may also aid in the relief of anxiety and depression, both of which can disrupt sleep. The only research that shows these vitamins help people sleep better has been done on older adults.

Moreover, on January 10, 2022, FDA announced in a letter of enforcement discretion a new qualified health claim for magnesium and reduced risk of high blood pressure.

Types of Magnesium

One of the biggest misconceptions about magnesium is that you just “need more” of it and you’ll be healthy and optimized.

But the TRUTH is, there are many different types of magnesium — and each plays a critical role in different functions in your body.

Frequently Asked Questions (FAQs)

1. What food is highest in magnesium?

• Avocados.
• Seeds and nuts: Almonds, Cashews, Flaxseed, Peanuts, Pumpkin seeds.
• Fatty fish.
• Legumes: Black beans, Edamame, Lima bean.
• Fiber-rich whole grains: Quinoa, Shredded wheat.
• Fruits and berries: Papaya, Raspberries, Tomato, Cantaloupe, Strawberries and Watermelon.
• Leafy Greens: Spinach, Swiss chard, Turnip greens, Beet greens, Collard greens, Broccoli, Brussels sprouts, Kale, Bok Choy, Romaine lettuce.

2. Magnesium Recommended Dose

The recommended dietary allowance for magnesium is 310 to 420 mg per day depending on your age and sex, but many experts believe you may need 600 to 900 mg per day, which is more in line with the magnesium uptake during the Paleolithic period.

As noted in Open Heart:
“Investigations of the macro- and micro-nutrient supply in Paleolithic nutrition of the former hunter/gatherer societies showed a magnesium uptake with the usual diet of about 600 mg magnesium/day …

This means our metabolism is best adapted to a high magnesium intake … In developed countries, the average intake of magnesium is slightly over 4 mg/kg/day … [T]he average intake of magnesium in the USA is around 228 mg/day in women and 266mg/day in men …”

The key to effectively using higher doses, however, is to make sure you avoid loose bowels as that will disrupt your gut microbiome, which would be highly counterproductive.

Magnesium Dose for Kids

> Toddlers (1 to 3 years old) – 80mg
> Kids (4 to 8 years old) – 130 mg
> Kids (9 to 12 years old) – 240mg

3. Signs of Magnesium Deficiency

Along with the measurement, you should track signs and symptoms of magnesium deficiency, such as..
  • Muscle spasms, especially “charley horses” or spasms in your calf muscle that happen when you stretch your leg, and/or eye twitches
  • Numbness or tingling in your extremities
  • Insulin resistance
  • High blood pressure, heart arrhythmias and/or coronary spasms
  • Increased number of headaches and/or migraines
  • Low energy, fatigue and/or loss of appetite
The Trousseau sign — To check for this sign, a blood pressure cuff is inflated around your arm. The pressure should be greater than your systolic blood pressure and maintained for three minutes. By occluding the brachial artery in your arm, spasms in your hand and forearm muscles are induced. If you are magnesium deficient, the lack of blood flow will cause your wrist and metacarpophalangeal joint to flex and your fingers to adduct.
