Excellent high doses of Vitamin D3 and K2 (MK-7) for calcium utilization and arterial health, but provides very little elemental calcium and is expensive per serving.
Quantity: 90
Dr. Mercola's Calcium with Vitamins D3 & K2 features a robust dose of 5000 IU of Vitamin D3, essential for maximizing calcium absorption, and a significant 180mcg of Menaquinone-7 (MK-7) form of Vitamin K2. MK-7 is widely recognized by nutritionists for its superior bioavailability and its crucial role in directing calcium to the bones and preventing its deposition in soft tissues like arteries, making it excellent for both bone and cardiovascular health. While these co-factors are optimally dosed, the elemental calcium contribution from 180mg of Calcium Carbonate is a very modest 72mg. This suggests the product is more intended as a sophisticated calcium *cofactor* supplement rather than a standalone high-dose calcium source. The premium formulation comes with a high price tag, at over $1 per serving, which might be prohibitive for those looking for a primary calcium source.
- Provides a high dose of Vitamin D3 (5000 IU), crucial for calcium absorption and overall health.
- Contains an optimal and high dose of Vitamin K2 (MK-7), essential for directing calcium to bones and preventing arterial calcification.
- The synergistic combination of D3 and K2 is highly effective for bone and cardiovascular health.
- Very low elemental calcium content (72mg) per serving, insufficient for a primary calcium supplement.
- Very high price per serving ($1.06), making it a costly option for general calcium supplementation.
- Consumers relying solely on this product for calcium intake will likely not meet their daily requirements and may need significant additional dietary or supplemental calcium.
