Overview
NatureWise's calcium citrate capsules provide 500mg of calcium per serving in a 90-count bottle, a 30-day supply, formulated as vegan, non-GMO, and gluten free for bone health.
Calcium citrate is generally considered easier to absorb than calcium carbonate, particularly for people with lower stomach acid, which is likely why this form was chosen over the more common carbonate version, though the listing doesn't compare absorption directly.
- 500mg calcium citrate per serving
- 90 capsules, 30-day supply
- Vegan and non-GMO
- Gluten free
Who it's for
Fits people looking for a vegan, easy-to-digest calcium supplement for bone support. Less suited to anyone who needs a higher per-capsule calcium dose, since 500mg per serving may mean multiple capsules to hit typical daily targets.
Strengths and trade-offs
Drawn from this product's published specifications.
- Vegan and non-GMO formula
- Easier-to-digest citrate form of calcium
- Free of common allergens like fish, peanut, and tree nut
- 500mg per serving may require more than one capsule daily for higher calcium targets
- 30-day supply means more frequent reordering
Performance notes
Calcium citrate doesn't require stomach acid for absorption the way calcium carbonate does, which is why it's often recommended for people who take it without food or who have digestive sensitivities, though as with any calcium supplement, spreading doses through the day tends to aid absorption more than one large dose.
