Vitamin D Supreme with K1/K2: Boost Absorption | Expert-Recommended


Designs for Health Vitamin D Supreme seems to live up to it's moniker- with useful amounts of vitamin K1 and K2, as they are required in proportion to the amount of Vitamin D for the D to be fully effective.


This recent change in my supplement plan is driven partly by a book obtained from Amazon, by a retired MD, Alexander Doumenach, who cites a large range of detailed clinical research programs to provide guidance, in "Vitamin D Vitamin C Iodine: Why more is better". Recommended reading, especially if you have a medical or biology background.


Vitamin Basics & Tips


Vitamin D plays a critical role in calcium absorption, bone health, and immune function. However, its effectiveness depends on synergistic nutrients like vitamins K1 and K2. Vitamin K1 aids blood clotting, while K2 directs calcium to bones and teeth, preventing arterial calcification. Research cited by Dr. Doumenach highlights that high-dose Vitamin D supplementation without adequate K vitamins may lead to imbalances, emphasizing the importance of combined formulas like Vitamin D Supreme.


Sunlight remains the primary natural source of Vitamin D, but factors like geography, skin tone, and sunscreen use limit synthesis. Dietary sources (fatty fish, fortified foods) often fall short, making supplements necessary for many. Current guidelines suggest 600–800 IU daily for adults, though some experts argue for higher doses based on individual needs and deficiency risks.


Emerging studies explore Vitamin D’s role beyond skeletal health, including immune modulation and inflammation reduction. Pairing it with Vitamin C and iodine, as proposed in Dr. Doumenach’s book, may amplify benefits, though consultation with healthcare providers is advised for personalized regimens.
