The nutrient quality is moderate due to the use of coral calcium (primarily carbonate) and magnesium oxide as the sole magnesium source, which are generally less bioavailable than citrate or chelated forms.
Best Naturals' Coral Calcium Plus offers a blend of calcium, primarily from coral sources, alongside magnesium and Vitamin D3. Coral calcium is a natural source that provides calcium carbonate along with various trace minerals. This formulation aims to deliver fundamental nutrients for bone health and overall mineral balance.
The product provides 350mg of calcium from coral calcium and 125mg of magnesium, primarily from magnesium oxide. While coral calcium offers a natural mineral profile, magnesium oxide is known for its high elemental magnesium content, but generally lower absorption rates. The inclusion of 10mcg (400 IU) of Vitamin D3 is a good addition, as it helps the body properly utilize calcium.
- Very affordable price per serving.
- Includes Vitamin D3 (10mcg/400 IU) to support calcium absorption.
- Coral calcium is a natural source of calcium, often with trace minerals.
- Offers a balanced calcium to magnesium ratio (approx. 2.8:1).
- Easy-to-take capsule form.
- Magnesium is exclusively from magnesium oxide, which has lower bioavailability.
- Lower dosages of calcium (350mg) and magnesium (125mg) compared to many alternatives.
- Coral calcium is primarily calcium carbonate, which may require stomach acid for optimal absorption.
- Those with low stomach acid may find calcium carbonate less effective.
- Magnesium oxide may cause digestive upset in sensitive individuals.
- Consult a healthcare professional if you have allergies to marine products or are taking other medications.
