What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Calcium and vitamin D3 have strong evidence for supporting bone density and mineral absorption. Vitamin C and boron provide additional support for immune function and skeletal health, though evidence for boron is more limited. This combination targets overall bone and systemic maintenance.

Vitamin D3 1000 plus Calcium intensive care is a mild all-natural formula designed to address the special requirements of virtually all individuals, particularly women, to consume extra vitamin D3 and calcium. This formula begins with 1,000 IU of vitamin D3, which has recently been recognized as perhaps the most important single vitamin to supplement separately. We then combine our Vitamin D3 1000 with the exceptionally mild and soluble sources of calcium found in our unique Calcium Intensive Care. Vitamin D has long been recognized for its essential role in the maintenance of all bone and skeletal tissues, since without vitamin D, calcium cannot be absorbed and utilized by the body. Although calcium’s role in bone health is unquestioned, the benefits of calcium cannot be realized without adequate levels of vitamin D, making vitamin D just as essential as calcium in any bone health regime. Vitamin D’s role in supporting the health of other body systems has recently made headlines in newspapers and the medical literature and experts now seek to substantially raise the recommended levels of vitamin D. The body can manufacture limited amounts of vitamin D when exposed to sunlight (via its damaging UV radiation); however, the aging process combined with our reduced exposure to sunlight and increased use of sunscreens makes our body’s production of vitamin D inadequate and unreliable at best. Making matters worse is the fact that vitamin D is not abundant in food, and is only present in very limited quantities in some fish and eggs. Recognizing this, Andrew Lessman has always given special attention to vitamin D3, providing higher levels than found in the leading multivitamins, while also including vitamin D3 in all his calcium and bone health products for over 30 years. Now, with our Vitamin D3 1000 plus Calcium Intensive Care you get 1,000 IU of vitamin D3 combined with the special ingredients present in our Calcium Intensive Care.

Best of all, this formula is extremely economical and guaranteed gentle even to the most sensitive stomachs.
