Are there any side effects from long-term use?

Can it be taken with other supplements or vitamins?
Can it be taken with other supplements or vitamins?

Are there any specific instructions for taking it safely?
Are there any specific instructions for taking it safely?
Take 1 capsule daily or as recommended by a healthcare professional. Taking with food improves tolerance. Space from antibiotics or bisphosphonates by at least 2 hours. For stress-depletion applications, evening dosing supports sleep-associated magnesium repletion.
How long until benefits are typically experienced?

Magnesium repletion occurs over 4-8 weeks of consistent daily supplementation. Stress-depleted magnesium may normalize in 4-6 weeks. Sleep quality and muscle relaxation improvements are often among the first benefits noticed, typically within 1-2 weeks of daily use.
