Vitamin D, the sunshine vitamin, has been touted as the most important supplement under the sun—and for good reason. As many as 75% of Australian may be deficient, because not only is it virtually impossible to get enough from food, but in today’s digital age, it’s unlikely you’re spending enough time in the sun. It also depends what time of year it is, what time of day and how high the sun is in the sky. For these reasons, high-doses of 5,000 IU or more are often recommended to support everything from bone and heart health to mood.
But, how often has someone recommended that you combine your high-dose of vitamin D with vitamin K and vitamin A? Together, these three powerful vitamins join forces to support your bones, heart, and immune system.
Here’s how it works. Vitamin D plays a critical role in calcium absorption into the bloodstream. Vitamin K is required to transport calcium from the bloodstream into the bone, supporting bone density and cardiovascular health. Additionally, vitamin A works with vitamin D to support your immune system.
A-D-K packs vitamins A (as retinyl palmitate), D3, K1 and K2 (as MK-4 and MK-7) into a convenient 5-in-1 punch. All forms of vitamins A, D and K are fat-soluble, which means they dissolve in fats and oils. Fat-soluble vitamins are absorbed along with fats in your diet and remain in the body longer than water-soluble vitamins. Bulletproof A-D-K uses a proprietary Brain Octane™ oil softgel to further aid in absorption of these fat-soluble vitamins.
One softgel, daily with food.
Amount Per Serving (1 Softgel):
Other Ingredients:
Medium chain triglycerides from highly refined coconut and/or palm kernel oil, olive oil, gelatine, purified water, glycerin, Brain Octane® oil (caprylic acid triglycerides from highly refined coconut oil), coloured with annatto.
Note: It’s important not to take excessive amounts of fat-soluble vitamins. As with any supplement, consult your healthcare provider before use, particularly if you are pregnant, nursing or taking medication.
Warning: Keep out of reach of children.
Bulletproof A-D-K uses the best form of vitamins in order to provide maximum benefits.
Vitamin A is commonly used interchangeably with beta-carotene (the stuff in carrots), but they are very different. There are two types of vitamin A: “Active” and Beta-Carotene. Unlike active vitamin A, beta-carotene must first be converted to retinol before the body can utilise it. Where retinol (from retinyl palmitate) absorption is as much as 90%, beta-carotene absorption can be as low as 9%. This means retinol is as much as 10-times more bioavailable than beta-carotene. That is why it is important to get your vitamin A from retinyl palmitate.
There are two main forms of supplemental vitamin D—D3 (cholecalciferol) and D2 (ergocalciferol). Vitamin D3 is readily absorbed because it is the same form your body naturally produces when it’s exposed to UV rays. It’s essential for calcium absorption and maintaining bone, teeth, immune and skin health.3 D3 is the preferred form of vitamin D supplementation, especially for those who have limited sun exposure.
Proper vitamin K levels are critical in transporting calcium from the bloodstream into the bone. Vitamin K helps to maintain normal calcium balance in the arteries, supporting heart and vascular health.1,2 However, it’s difficult to get adequate amounts of vitamin K from food alone. Three forms of vitamin K that are readily available to the body are K1 and K2 from both MK-4 (menaquinone-4) and MK-7 (menaquinone-7). Providing these three vitamin K forms ensures quick and sustained availability because each of them are utilised by the body differently.
In each convenient softgel, A-D-K delivers 1,000mcg K1, 1,500mcg MK-4 and 300mcg MK-7.
Brain Octane oil is a quality fat, distilled from the most potent part of the coconut. Since vitamins A, D and K are fat-soluble, it is difficult for the body to absorb them if they’re not taken with a fat. Delivering all of these vitamins in Bulletproof’s proprietary Brain Octane oil softgel helps to ensure their absorption.
A: It is recommended to keep most supplements out of reach of children because they’re not formulated specifically for children. While this remains the case for vitamins A, D and K, the upper limit of vitamin A is significantly lower for children, increasing the potential risk. With this in mind, and as a cautionary measure, we felt it best to use a child resistant cap on this supplement. Please keep out of reach of children.
Q: Can I take more than the recommended amount?
A: A-D-K was formulated to contain an effective dose at the recommended serving size. As with any supplement, please consult your healthcare provider to determine the right dose for you.
Q: What is used for the colour?
A: Natural colour variation may occur due to the complex mix of vitamins used in A-D-K, so annatto is used for uniformity. Annatto is a natural red-orange condiment, the result of extracting carotenoids from fruit seeds of the achiote tree. The achiote tree originated in tropical areas of Central, South and North America where natives historically used it as both a spice and to create red body paint.
Q: Are any of the vitamins derived from soy?
A: No, there is no soy in this product.
Q: Do I need to take this with food?
A: Since vitamins A, D and K are fat-soluble, they are best taken with a fat-containing meal.
Q: For Vitamin A (retinol), what is the relationship between mcg and IU?
A: Per new FDA regulations, vitamin A is now declared as micrograms (mcg) of Retinol Activity Equivalents instead of International Units (IU). One IU of retinol is equal to 0.3 mcg Retinol Activity Equivalents. That makes the 900 mcg of vitamin A in this product equal to 3,000 IU of retinol.
