21st Century's 600 Calcium Supplement provides 600mg of elemental calcium as calcium carbonate in a tablet form. This dosage is considered an optimal single serving for absorption, especially when taken with food to aid digestion. The product's most striking feature is its extremely low price per serving ($0.02), making it one of the most economical choices available. However, a major deficiency is the complete lack of Vitamin D3, which is absolutely essential for the body to absorb calcium from the gut and utilize it effectively for bone mineralization. It also lacks other important cofactors like Vitamin K2.
- Exceptionally low price per serving, making it very budget-friendly.
- 600mg elemental calcium is an ideal dose for single-serving absorption.
- Calcium carbonate is a widely available and common form of calcium.
- Crucially lacks Vitamin D3, which is essential for calcium absorption.
- Does not contain Vitamin K2, important for proper calcium distribution.
- Requires stomach acid for optimal absorption, best taken with food.
- Without adequate Vitamin D3, the calcium consumed from this supplement may not be properly absorbed or utilized by the body, significantly diminishing its benefits.
- Not ideal for individuals with malabsorption issues or low stomach acid unless taken with acid enhancers.

Categories
Calcium 40.0
An exceptionally budget-friendly source of calcium carbonate, providing a standard dose, but its utility is greatly diminished by the omission of Vitamin D3, which is essential for calcium absorption.
Goals
Bone Health 40.0
Provides a suitable amount of elemental calcium, which is a building block for bones, but the critical absence of Vitamin D3 severely hinders its absorption and ultimate benefit for bone density and strength.
Joint Health 35.0
Offers basic calcium support for skeletal structure, however, without synergistic nutrients like Vitamin D3, its comprehensive contribution to joint health and overall mobility is limited.
Fitness 35.0
Supplies calcium for muscle function, but its overall support for fitness is foundational due to the lack of other essential cofactors that enhance performance and recovery.
