Overview
Pure Encapsulations' Potassium Magnesium combines both minerals in aspartate form, sold as 180 vegetarian capsules aimed at supporting heart, muscle, bone and nerve function.
The aspartate form is the notable choice here, since some brands use oxide or citrate forms of magnesium that absorb differently. At 180 capsules the bottle is sized for extended daily use, though the exact capsule count per serving is not listed in this data.
- Potassium magnesium aspartate
- 180 vegetarian capsules
- Unflavored formula
- Supports cardiovascular, muscle, bone and nerve health
Who it's for
Fits people looking for a combined potassium and magnesium capsule in a vegetarian formula, particularly those already choosing Pure Encapsulations for its typically minimal-filler capsules. Not for anyone who needs only one of the two minerals or a flavored chewable.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines potassium and magnesium in one capsule
- Vegetarian capsule formula
- Unflavored, no added flavoring
- Per-serving capsule dose not listed in this data
- Aspartate form may not suit those wanting citrate or glycinate

Performance notes
Magnesium aspartate is one of several bonded forms used in supplements, chosen by some formulators for its absorption profile compared to magnesium oxide. The listed benefit areas span cardiovascular, metabolic, muscle and nervous system support, reflecting the broad role both minerals play in the body rather than one targeted use.
