The essentials

A closer look.

Source Naturals Magnesium Malate 1250mg delivers magnesium bound to malic acid, a form chosen for its role in cellular energy metabolism via the Krebs cycle. Each serving provides 1250mg of the magnesium malate complex, supporting muscle comfort, energy production, and normal neuromuscular function. A practical option for adults seeking a well-tolerated magnesium form.

Why It's Worth Considering: The malate chelate may offer improved gastrointestinal tolerability compared to magnesium oxide, while malic acid itself contributes to ATP synthesis pathways, making this combination relevant for those focused on muscle and energy support.

More category questions

What is the best form of magnesium to take?

Magnesium glycinate (bisglycinate chelate) is widely considered the best form for sleep, anxiety, and muscle cramps due to high bioavailability and zero laxative effect. Citrate is better for constipation. Threonate may be superior for cognitive function as it crosses the blood-brain barrier. Oxide has only 4-5% absorption and is primarily a laxative.

Does magnesium glycinate cause diarrhea?

No. Unlike magnesium citrate and oxide which draw water into the intestines (osmotic laxative effect), glycinate is chelated and absorbed through a different pathway that does not affect GI motility. It is the most GI-friendly magnesium form available.

When is the best time to take magnesium?

Take 1-2 hours before bed for sleep benefits. The glycine component promotes relaxation via GABA receptor activity. For general supplementation, any time works — glycinate does not require food for absorption.

How do I know if I am magnesium deficient?

Standard blood tests (serum magnesium) are unreliable — only 1% of body magnesium is in the blood. Signs include muscle cramps, poor sleep, anxiety, eye twitches, chocolate cravings, and headaches. Since 80%+ of adults are suboptimal, supplementation is generally recommended.

Can I take magnesium with other supplements?

Yes, but separate from zinc, calcium, and iron by 2+ hours (they compete for absorption). Magnesium pairs well with Vitamin D3, K2, and B6 taken together.

How much magnesium should I take daily?

The RDA is 310-420mg/day for adults. Most functional medicine practitioners recommend 400-600mg for therapeutic benefit. Start with the product's recommended dose and adjust based on response.
