insights Analysis
Metabolic Maintenance's Vitamin D-3 offers a potent blend of 10,000 IU of Vitamin D3 (Cholecalciferol) and 300mg of Vitamin C (Ascorbic Acid). Both nutrients are well-established for their roles in immunity, bone health, and general well-being. The high dose of Vitamin D3 can be particularly beneficial for individuals with diagnosed deficiencies or those needing aggressive repletion, though it's advised to consult a healthcare professional for such high dosages for prolonged use. Vitamin C complements this by providing antioxidant support and boosting immune function. However, with a price per serving of 43, it stands out as a more expensive option compared to many widely available, equally effective Vitamin C and D supplements. Reviews suggest customer satisfaction with the product's efficacy, but the price point and the exceptionally high D3 dose might not be suitable for everyone's needs or budget.
- Provides a very high 10,000 IU dose of Vitamin D3, ideal for addressing significant deficiencies.
- Includes a beneficial 300mg of Vitamin C, synergistically supporting immunity and overall health.
- Utilizes Cholecalciferol (D3) and Ascorbic Acid, which are highly bioavailable forms of the respective vitamins.
- The 10,000 IU Vitamin D3 dose may be too high for general daily use without professional medical guidance.
- The price per serving is relatively high compared to many single-ingredient Vitamin D or Vitamin C supplements on the market.
- The review count (349) is moderate, suggesting less widespread adoption compared to some highly-reviewed competitors.
