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.
