Magnesium Liquid by Pure Encapsulations is a liquid magnesium supplement formulated with 215 mg of magnesium citrate. Additionally, it contains 20 mg of vitamin B6. Although the formula is suitable for vegetarians, the liquid is sweetened with stevia and glycerin, a type of carbohydrate called a sugar alcohol. Some consumers found the liquid to have an overly sweet flavor, and it may not be the most suitable choice for those watching their sugar intake.

Triple Complex Magnesium
by BioEmblem

Triple Complex Magnesium by BioEmblem is formulated with three well-absorbed forms of magnesium: magnesium glycinate, citrate, and malate. One container contains 90 plant-based capsules to provide a 45-day supply. Like our number one choice, this magnesium blend is designed to maintain healthy muscles and bones, as well as support sleep and relaxation. However, this formula does not contain zinc to provide additional immune support and contains less magnesium than our top choice. This magnesium supplement comes in second place because some consumers reported that the capsules were difficult to swallow.

Magnesium Glycinate Complex by Klaire Labs comes in third on our list. This magnesium complex is formulated with two forms of magnesium: magnesium glycinate and magnesium oxide. It delivers 100mg (24% DRV) of magnesium in each plant-based capsule. Although this formula contains bioavailable magnesium glycinate, it is also formulated with magnesium oxide and may be less potent than the other magnesium supplements on this list. Our team also noted that it contained only one third of the amount of magnesium as our top choice on this list.

Magnesium Bisglycinate by Thorne is formulated with two forms of magnesium glycinate to support restful sleep and muscle relaxation. Although it contains this bioavailable, easily absorbed form of magnesium, it is formulated with less magnesium than our number one pick. The powdered form may be a good choice for those who don’t like to swallow pills or capsules, however some consumers were not big fans of the flavor. It is also less convenient to use, as it must be stirred into liquid 2-3 times per day. 

Magnesium Bisglycinate by Thorne

The Bottom Line 

Powder form may be less convenient

Unappealing flavor to some

Only contains one form of magnesium

Only 200 mg magnesium

Magnesium may help promote faster muscle recovery after exercise and support better sleep quality, relaxation, and energy levels. 

Studies also suggest that because magnesium is so important for brain health, it may be beneficial for promoting better mood and aiding symptoms of anxiety.

Despite all its benefits, it is estimated that approximately 50% of US adults get less than the daily recommended amount of magnesium.

What’s wrong with most magnesium supplements on the market? 

When it comes to finding the right supplements, it can get pretty complex. There are endless products to choose from formulated with different forms of magnesium that may target different needs.

Most types of magnesium found in supplements are bound with other compounds to make them more easily absorbed. However some types are more absorbable, or bioavailable than others. It’s important to look out for ones with high bioavailability so you get the most benefits.

Unclear Labels: A quality magnesium supplement should clearly list exactly what’s included in the formula. Avoid products lacking transparency that don’t list all of the specific ingredients included in the formula.

Missing Safety Testing & Certifications: Choose a magnesium supplement that has been independently third-party lab tested and manufactured in a GMP-certified facility. Since supplements are not regulated by the FDA in the United States, these precautions will guarantee that the product is top quality and free from unwanted extras, such as contaminants, traces of heavy metals, or pesticides.

False or Misleading Claims: Beware of any supplements that claim their product treats or cures any specific disease or ailment, or promises miraculous, unrealistic, or misleading results. Always speak to your doctor before starting a new supplement routine.

Suspiciously Cheap Products: When it comes to your health, this is definitely not an area to test out suspiciously cheap products. There are plentiful options to choose from that are high value and still affordable. In this case, you do get what you pay for!

All magnesium supplements are NOT created equal.

Unfortunately, many generic magnesium supplements are packed with synthetic fillers, artificial coloring, or a long list of chemical ingredients most people can’t even pronounce.

Choosing the best possible magnesium formula all comes down to knowing what to look for and what to avoid so that you never waste your money on ineffective, low-value, or potentially harmful products.

Here are the top things to avoid when shopping for a high-quality magnesium supplement:

Why is magnesium important?

Loss of appetite

Vomiting

Fatigue
