Overview
A 300 mg potassium capsule that splits the dose between potassium bicarbonate and potassium glycinate, aimed at supporting healthy blood pressure levels. The bottle holds 120 capsules.
Using two potassium forms, bicarbonate and glycinate, combines an alkalizing form with one associated with better tolerance, rather than relying on a single potassium salt. Designs for Health markets it specifically toward blood pressure support rather than general electrolyte replacement.
- 300 mg potassium per capsule
- Two forms: bicarbonate and glycinate
- 120 vegetarian capsules
- Gluten free and vegan
Who it's for
Suited to people looking for a dedicated potassium capsule as part of blood pressure management, ideally under guidance from a healthcare provider given how potassium interacts with certain medications. Not intended as a post-workout electrolyte replacement, where sodium and other minerals typically matter more.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines two forms of potassium in one capsule
- Gluten free, vegan and vegetarian
- 120-count bottle for extended use
- Positioned specifically for blood pressure support
- 300 mg per capsule is a modest dose relative to daily potassium needs
- Single-mineral formula, not a full electrolyte blend
Performance notes
Splitting the dose between potassium bicarbonate and potassium glycinate is meant to combine two absorption and tolerance profiles rather than relying on one salt form. At 300 mg per capsule and 120 capsules per bottle, the count supports extended daily use.
