A good fit for Comparing a vegan magnesium capsule with a stated elemental amount and a larger 180-capsule bottle.
- The listing separates 300 mg elemental magnesium from the 1500 mg compound headline, making comparisons with other magnesium products more meaningful.
- The plant-based capsules can be opened according to the retailer, offering an alternative for people who dislike swallowing tablets.
The buffered ingredients combine bisglycinate and oxide; glycinate branding does not establish better sleep, absorption or digestive comfort for this exact product.

The details that matter.
- Preparation
- Buffered magnesium bisglycinate: magnesium bisglycinate and magnesium oxide
- Declared elemental magnesium
- 300 mg per two capsules
- Compound headline
- 1500 mg per two-capsule serving; not 1500 mg elemental magnesium
- Photographed pack
- 180 vegan capsules
- Capsule shell
- Hydroxypropyl methylcellulose
- Check elemental magnesium across all products you take. The NHS notes that most people can meet their magnesium needs through a varied diet.
- Kidney disease and medicines that interact with magnesium need individual review; ask a pharmacist about medicine timing.
- The retailer describes two capsules with food. Follow the received label and professional advice rather than assuming the full stated serving is appropriate for you.
Cycling & duration.
Ingredient timeframes describe the cited preparation; they do not establish a cycle for every finished formula.
Magnesium glycinate
- On/off pattern
- No established magnesium-glycinate on/off schedule.
- Duration & evidence
- Nutrition-related use follows the assessed need. Study duration only: a 2025 bisglycinate sleep trial assessed 4 weeks, not an indefinitely repeatable sleep course.
- When to review
- Review elemental magnesium intake, digestive tolerance and kidney health; review persistent poor sleep separately.
- The short sleep trial does not establish long-term effectiveness or a required washout.
- Kidney impairment can increase magnesium toxicity risk; taking periodic breaks is not a substitute for review.
