<p>The combination of a high elemental calcium dose (from calcium carbonate) with a good amount of Vitamin D3 is a strong point for nutrient quality, as D3 is vital for calcium's efficacy.</p><p>While calcium carbonate isn't the most bioavailable form, the high dose and D3 pairing make it effective.</p>
This Nature's Bounty supplement combines a substantial 1200 mg of elemental calcium from calcium carbonate with 25 mcg (1000 IU) of Vitamin D3. This pairing is important as Vitamin D3 significantly aids the body in absorbing and using calcium, which is crucial for supporting strong bones and healthy nails. The softgel form may be easier for some to swallow compared to large tablets.
Calcium carbonate is a common and effective form of calcium, providing a high amount of elemental calcium per dose. It's often recommended to take it with food to help with absorption. This product is a practical option for those seeking comprehensive calcium support with the added benefit of Vitamin D3.
- Contains a significant amount of elemental calcium (1200 mg).
- Includes Vitamin D3 (1000 IU), vital for calcium absorption and utilization.
- Softgel form may be easier to swallow for some users.
- Very affordable price per serving.
- Calcium carbonate may require stomach acid for optimal absorption and can sometimes cause mild digestive upset.
- Large dose might need to be split for better absorption, as the body can only absorb a limited amount of calcium at once.
