Overview
Nutricost's potassium citrate capsule is dosed at 99mg per capsule and sold in a 500-count bottle, formulated gluten free and soy free for buyers wanting a long-lasting supply.
At 99mg per capsule, this sits on the lower end for a potassium supplement, so multiple capsules per serving may be needed to reach a meaningful dose, worth checking against your target intake. The 500-count bottle offsets that modest per-capsule strength with a long supply, useful if you're taking several capsules daily. Gluten and soy free are the only dietary details listed.
- 500 capsules per bottle
- 99mg potassium citrate per capsule
- Gluten free
- Soy free
Who it's for
Suits buyers who want a large supply of gluten and soy free potassium citrate capsules and don't mind taking multiple capsules to reach their target dose. Less suited to anyone wanting a high single-capsule potassium strength.
Strengths and trade-offs
Drawn from this product's published specifications.
- Gluten free and soy free
- Single-ingredient potassium citrate
- 99mg per capsule is a modest dose
- Likely needs multiple capsules per serving
Performance notes
99mg per capsule is a modest potassium citrate dose, meaning most buyers would take more than one capsule to reach typical supplemental targets. The 500-count bottle is built for that pattern, offering a long supply even at several capsules per day. Gluten free and soy free cover the dietary claims listed.
