Liquid D and K, brought to you by Douglas Laboratories, is a remarkable product that provides a delicious and unique liquid formulation packed with substantial amounts of vitamins K1 and K2, as well as vitamin D3, to promote optimal bone health.

Extensive research supports the notion that higher intake of vitamin K, through both dietary sources and supplements, can have a positive impact on bone health. Contrary to popular belief, vitamin K is not a single molecule, but rather a group of similar forms, including K1 (phylloquinone) and K2 (menaquinone). Liquid D and K has been carefully crafted to incorporate the most vital molecular forms of vitamin K, ensuring your health is at its best.

While vitamin K1 is abundant in green vegetables such as spinach, lettuce, and broccoli, it can be challenging to obtain sufficient amounts from diet alone, as this molecule can be tightly bound to the plant's chloroplast membrane. Vitamin K1 is widely recognized for its significant role in the body's normal blood clotting mechanisms.

On the other hand, vitamin K2 is not commonly found in the average diet. Only a few products, like certain meats and fermented foods, contain this relatively rare form of the vitamin. Vitamin K2 is comprised of several different molecules, including MK-n, where n represents a number. MK-4, found in specific animal meats and liver, as well as MK-7, found in fermented cheeses and soy products like Natto, are two extensively studied forms of vitamin K2.

Supplementing with this vitamin is essential, as most individuals do not receive adequate amounts of vitamin K2 through diet alone. Several human studies demonstrate that vitamin K plays a crucial role in maintaining bone health. It has been shown to decrease calcium excretion and is involved in the gamma-carboxylation of osteocalcin, a key protein for healthy bone formation as it aids in the binding of calcium to the bone matrix called hydroxyapatite. Moreover, studies suggest that vitamin K2 may also support cardiovascular health and maintain normal arterial elasticity.

Although vitamin K1 has shown promise in studies, vitamin K2 is believed to have additional beneficial effects since the body possesses a natural preference for accumulating this vitamin in tissues like bone. MK-7, a natural form of vitamin K2, is particularly known for its rapid bioavailability in the body, and a low dosage of just 45 mcg can effectively support bone health.

Vitamin D3 is widely recognized for its role in regulating calcium and bone metabolism, and as we age, our vitamin D levels often decline. Additionally, factors like advancing age and living in northern latitudes can contribute to vitamin D deficiency. Vitamin D supports bone formation by increasing the expression of vital compounds like osteocalcin from osteoblasts. It can also aid in breaking down bone and mobilizing calcium when needed elsewhere in the body. Many scientists now emphasize the importance of vitamin D supplementation at levels higher than previously recommended to maintain healthy bone remodeling as we age.

Liquid D and K is an excellent dietary supplement for individuals who want to enhance their daily intake of these essential vitamins. Promote bone health and enjoy the benefits of Liquid D and K from Douglas Laboratories.
