Vitamins A-D-K 30ct

Bulletproof Vitamins A-D-K provides a synergistic combination of three essential fat-soluble vitamins in a Brain Octane C8 MCT oil softgel designed for effective absorption and utilisation. This comprehensive formula supports bone health, immune function, cardiovascular health, and proper calcium metabolism through the complementary actions of vitamins A, D, and K working together.

Vitamins A, D, and K are fat-soluble vitamins, meaning they dissolve in and are absorbed with dietary fats. Many people take these vitamins in dry capsules or tablets which provide poor absorption because the vitamins aren't delivered with the fats needed for uptake. Bulletproof solves this by formulating A-D-K in Brain Octane C8 MCT oil, ensuring effective absorption by providing the fat matrix these vitamins require.

Vitamin D3 (cholecalciferol) is provided at 5000 IU per softgel, a science backed dose that supports effective vitamin D status for most people. Vitamin D is crucial for immune system function, regulating immune responses and supporting the body's defences. It's essential for bone health by promoting calcium absorption from the digestive tract into the bloodstream. Without adequate vitamin D, even high calcium intake won't support bone health because the calcium isn't absorbed.

Vitamin D also supports cardiovascular health, mood and mental health, muscle function, healthy body response, and overall cellular health. Unfortunately, vitamin D deficiency is extremely common, especially in northern latitudes, during winter months, among people with darker skin, and in those who avoid sun exposure or use sunscreen religiously. Supplementation ensures adequate levels year round.

Vitamin K is provided in three forms: K1 (phylloquinone) at 1000mcg, K2 as MK-4 (menaquinone-4) at 1500mcg, and K2 as MK-7 (menaquinone-7) at 300mcg. This three form approach ensures comprehensive vitamin K support because each form has unique properties and roles.

Vitamin K1 is the most common form found in leafy green vegetables, but it's typically under absorbed from food because it's bound tightly to plant fibres. K1 primarily supports blood clotting function, ensuring proper coagulation when needed.

Vitamin K2 forms are where the real benefit lies for bones and cardiovascular health. Vitamin K2 helps activate proteins that transport calcium from the bloodstream into the bones where it belongs and out of soft tissues like arteries where calcium deposits cause problems. This is why vitamin K2 is essential for both bone density and cardiovascular health, it ensures calcium goes to the right places.

MK-4 and MK-7 are utilised differently by the body. MK-4 may have broader distribution throughout tissues, while MK-7 remains in the bloodstream longer, up to 48 hours, providing sustained vitamin K2 activity. By including both, Bulletproof ensures comprehensive vitamin K2 support.

Vitamin A as retinyl palmitate provides 900mcg per softgel. Vitamin A is essential for immune function, working synergistically with vitamin D to support immune cell development and activity. It's crucial for vision, particularly night vision and adaptation to darkness. Vitamin A supports skin health, mucous membrane integrity, reproductive health, and cellular differentiation.

The synergy between these three vitamins is remarkable. Vitamins A and D work together for immune support, each supporting the other's effects. Vitamins D and K2 work in tandem for bone and cardiovascular health, with D promoting calcium absorption and K2 directing where that calcium goes. Vitamin A supports the actions of both D and K through various mechanisms.

For bone health, the A-D-K combination is effective. Vitamin D contributes to calcium absorption, vitamin K2 contributes to the activation of osteocalcin which binds calcium into bone matrix, and vitamin A supports bone remodeling processes. This comprehensive support helps maintain bone density, reduce fracture risk, and support skeletal health throughout life.

For cardiovascular health, vitamin D supports healthy blood pressure and heart function, vitamin K2 contributes to healthy arterial function by helping activate matrix Gla protein which inhibits calcium deposits in arteries, and vitamin A supports endothelial health. Together they promote cardiovascular wellness.

For immunity, vitamins A and D are both crucial immune regulators. They support the development and function of various immune cells, help regulate immune responses to be neither too weak nor overactive, support mucous membrane barriers that are the first line of defence, and support the body's natural defence function.

Vitamin D also contributes to normal energy yielding metabolism, while the synergistic combination of A, D, and K ensures each vitamin is utilised efficiently by the body.
