Analysis

Nature's Bounty Calcium 1200 mg Plus 25 mcg (1000 IU) Vitamin D3 combines a high dose of calcium carbonate with a beneficial amount of Vitamin D3, which is crucial for calcium absorption in the gut. Calcium carbonate is a widely available and economical form of calcium. While the 1200mg dosage is significant, it's generally recommended to take calcium in smaller, split doses (e.g., 500-600mg) for optimal absorption, as absorption efficiency decreases with larger single doses. This product lacks Vitamin K2, a vital cofactor for directing calcium to the bones and preventing arterial calcification, which is a common oversight in many basic calcium supplements.

Pros
  • Includes essential Vitamin D3, vital for calcium absorption.
  • Very good price per serving ($0.11), offering excellent value for calcium and D3.
  • High elemental calcium content per serving.
Cons
  • 1200mg of calcium carbonate in a single serving is a high dose that may not be fully absorbed and can cause digestive discomfort.
  • Does not contain Vitamin K2, which is important for proper calcium distribution in the body and arterial health.
  • Calcium carbonate requires stomach acid for absorption, so it's best taken with food.
Warnings
  • Individuals with low stomach acid may not absorb calcium carbonate effectively.
  • Taking large doses of calcium without Vitamin K2 could potentially lead to calcium deposition in soft tissues, although this risk is primarily associated with extremely high dosages over time.
