Magnesium is a mineral valued all year round, but it becomes especially helpful during periods of increased fatigue, exhaustion, or general weakness. This essential element is, in many ways, pure energy packed into unassuming tablets or capsules. In reality, magnesium comes in many different forms — powders, capsules, liquids, tablets — but regardless of the delivery method, what matters most are the results. Magnesium may help relieve muscle cramps, support the skeletal system, contribute to normal cardiovascular and nervous system function, and support overall immunity. It is also a go-to mineral during stressful periods, as it may help calm the body, reduce the negative effects of stress, and contribute to maintaining healthy cholesterol levels.
What Makes the Best Magnesium Supplement?
The best magnesium supplement is not necessarily the cheapest one on the shelf. In fact, budget-priced magnesium products are rarely the most effective, primarily because they tend to contain poorly bioavailable forms of the mineral. These products may boast magnesium content of up to 500% of the daily recommended intake, but that figure means very little if the body can only absorb a fraction of it. So what should you look for instead of a low price tag?
The form of magnesium is the most important factor. This information is always listed in the product's ingredients. The most bioavailable forms include magnesium citrate, magnesium taurate, magnesium glycinate (bisglycinate), magnesium malate, and magnesium L-threonate. Single-ingredient supplements containing one of these forms offer not only superior absorption but also the assurance that the product is free of unnecessary fillers. Multi-ingredient blends can be harder to assess in terms of real absorption.
It is also worth being cautious with effervescent tablets — they typically contain very little magnesium in bioavailable form and are loaded with fillers that may actually hinder absorption. While every supplement requires some inactive ingredients to maintain its form, the formula should be free of polishing agents, phosphates, artificial colourants, and magnesium stearate. The latter is not bioavailable and tends to accumulate in the body.
Many products advertise 200%, 300%, or more of the daily recommended intake — which makes overdosing a real possibility. Instead of relying on marketing claims, check the composition. A single tablet — typically one daily dose — should contain a minimum of 50 mg of elemental magnesium. Citrate-based supplements often provide 100–250 mg per dose, which remains within a safe range. The upper end of 250 mg is recommended during periods of heightened stress, fatigue, or when replenishing a known deficiency.
[tip:When reading supplement labels, always look for the amount of elemental magnesium — not the total weight of the magnesium compound. For example, "magnesium citrate 500 mg" may only provide around 80 mg of actual magnesium.]
Why Brand Quality Matters
With hundreds of magnesium supplements available on the market, does it make sense to choose products from reputable, established brands? Absolutely. Supplements from well-regarded manufacturers typically offer higher-bioavailability magnesium forms, fewer unnecessary fillers, and greater transparency about their ingredients. They also tend to be more suitable for vegetarians and vegans, replacing animal-derived gelatine with plant-based alternatives that may even improve magnesium absorption.
