Magnesium is a vital mineral involved in numerous bodily functions, including muscle and nerve health, blood pressure and blood sugar control, and energy creation.
But did you know that many people don’t get enough magnesium from their diet?
Why do we need magnesium?
Magnesium plays a crucial role in more than 300 enzyme reactions within our bodies and supports various physiological systems that are essential for maintaining our cardiovascular and metabolic health. According to Medical News Today, magnesium is important for:
-
Muscles and nerves to work properly
-
Keeping blood sugar and blood pressure at the right level
-
Making proteins, bone, and DNA (genetic material)
A lack of sufficient magnesium can lead to various symptoms, including headaches, loss of appetite, nausea, vomiting, fatigue, weakness, numbness, tingling, muscle cramps, seizures, and an irregular heartbeat. Furthermore, individuals with low magnesium levels may have an increased risk of developing conditions like high blood pressure, heart disease, stroke, type 2 diabetes, osteoporosis, and migraines.
How can we get enough magnesium?
The best way to get enough magnesium is through a balanced diet that includes a variety of foods rich in this mineral. Some of the foods that are high in magnesium are:
-
Green leafy vegetables
-
Legumes
-
Nuts and seeds
-
Whole grains
-
Fatty fish
-
Bananas
-
Dark chocolate
The recommended daily intake of magnesium varies based on age, sex, and life stage. For adults between 19 and 30 years old, the RDI is 400 milligrams for men and 310 milligrams for women. For those 31 years and older, the recommendation increases slightly to 420 milligrams for men and 320 milligrams for women. Pregnant and breastfeeding women need between 310 and 400 milligrams daily, depending on their age.
Meeting your daily magnesium requirements through diet isn’t always easy. Factors such as depleted soil, processing of foods, digestive problems that affect nutrient absorption, the use of certain medications, alcohol intake, chronic stress, or increased bodily demands due to illness or exercise can all contribute to insufficient magnesium levels. For those facing these challenges, a magnesium supplement may be a practical solution.
What are the best magnesium supplements online?
If you’re considering buying magnesium supplements online, you’ll see there are quite a few options. Keep in mind that your body absorbs and uses some forms of magnesium better than others.
Here are some of the best magnesium supplements available online based on their quality, effectiveness, customer reviews, and price.
Life Extension Magnesium Caps
Life Extension Magnesium Caps provide a potent dose of 500 mg of magnesium per capsule, utilizing a blend of three different forms – magnesium oxide, citrate, and succinate – to support overall magnesium levels in the body. This formulation aims to maximize the potential benefits of magnesium, including supporting cardiovascular health, promoting strong bones, and contributing to healthy nerve and muscle function.
Life Extension is a well-regarded brand known for its commitment to scientific research and high-quality ingredients, making these capsules a convenient option for those looking to supplement their magnesium intake with a trusted product.

21st Century Magnesium
21st Century Magnesium presents a budget-friendly and widely accessible way to supplement magnesium. Usually available as tablets containing around 250mg of magnesium, it commonly uses magnesium oxide as its main source. While magnesium oxide has a high magnesium content, its absorption rate is generally less efficient compared to forms like bisglycinate or citrate.
Consequently, while 21st Century Magnesium can help meet daily magnesium requirements for supporting muscle and nerve function, bone health, and energy production, those prioritizing optimal absorption might explore alternative forms or higher dosages, always in consultation with a healthcare professional.

NOW Foods Magnesium Glycinate provides a well-absorbed form of this essential mineral by binding magnesium to the amino acid glycine, which is known to enhance intestinal uptake. This formulation is often favored for its gentleness on the stomach, reducing the likelihood of digestive upset sometimes experienced with other magnesium forms.
By delivering magnesium in this bioavailable form, NOW Foods aims to support healthy muscle and nerve function, promote relaxation and restful sleep, and contribute to overall well-being. It’s a popular choice for individuals seeking an effective magnesium supplement that is also well-tolerated.

The inclusion of trace minerals further contributes to its comprehensive mineral profile.
