Vitamin A helps regulate the immune system, while D3 supports the activity of immune cells. Together, they promote a healthy immune response.*\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBone Health:\u003c\/strong\u003e Vitamin D3 enhances calcium absorption from the gut, and vitamin K2 (MK-7) helps incorporate that calcium into the bone matrix. Vitamin A also plays a role in bone remodeling. This triple-action approach supports strong, healthy bones.*\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCirculatory Health:\u003c\/strong\u003e Vitamin K2’s activation of matrix GLA protein helps maintain arterial flexibility by directing calcium away from blood vessels. This supports normal cardiovascular function.*\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVision and Skin:\u003c\/strong\u003e Vitamin A is essential for maintaining healthy vision, particularly in low light, and supports skin integrity by promoting normal cell turnover.*\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow These Nutrients Work Together\u003c\/h2\u003e\u003cp\u003eUnderstanding the synergy behind this trio reveals why they are best taken together. Vitamin A (as retinyl palmitate) activates retinoid receptors that regulate gene expression for immune function and cell differentiation. Vitamin D3 (cholecalciferol) is converted to its active form, stimulating calcium-binding proteins that enhance intestinal calcium absorption. Vitamin K2 (menaquinone-7) then activates osteocalcin, which binds calcium into the bone matrix, and matrix GLA protein, which inhibits calcium deposition in soft tissues like blood vessels. This coordinated action ensures calcium is utilized efficiently and safely, making the combination far more effective than any single nutrient alone. Dr. Mercola’s ADK formula provides these three in a balanced ratio for convenient, comprehensive support.*\u003c\/p\u003e\u003ch2\u003eWhat to Look For in an ADK Supplement\u003c\/h2\u003e\u003cp\u003eNot all ADK supplements are created equal. Dr. Mercola’s formula stands out because it provides 5000 IU of vitamin A (as retinyl palmitate), 5000 IU of vitamin D3 (from lanolin), and 180 mcg of vitamin K2 as MK-7—a form with a longer half-life that supports steady levels. The K2 is derived from fermented chickpeas instead of soy, making it suitable for those avoiding soy allergens. The vitamin A is free from synthetic preservatives like EDTA and BHT. The product is non-GMO and made to premium quality standards. When choosing an ADK supplement, look for the form of each vitamin, sourcing, and third-party testing for purity and potency.\u003c\/p\u003e\u003ch2\u003eRecommended Dosage and Usage\u003c\/h2\u003e\u003cp\u003eTake one (1) capsule daily with a meal containing fat for optimal absorption. Do not exceed the recommended dose. As with any dietary supplement, consult your health-care professional before use, especially if you are pregnant, nursing, taking medication (particularly blood thinners), or have a medical condition. Store in a cool, dry place, away from direct sunlight. Always read the label and directions for use.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThis product has not been evaluated by Health Canada. It is not intended to diagnose, treat, , or prevent any disease.\u003c\/em\u003e\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eCan I take this with other supplements?\u003c\/h3\u003e\u003cp\u003eYes, but because ADK contains fat-soluble vitamins, it’s best taken with a meal containing fat. If you are already taking separate D3 or K2 supplements, adjust dosage accordingly. Always consult your health care provider before combining multiple supplements.\u003c\/p\u003e\u003ch3\u003eIs it safe for long-term use?\u003c\/h3\u003e\u003cp\u003eWhen taken as directed (one capsule daily), this product is formulated for long-term use. However, because vitamin A is stored in the body, it’s important not to exceed the recommended dose. Pregnant women should avoid high-dose vitamin A unless supervised by a physician.\u003c\/p\u003e\u003ch3\u003eDoes it contain soy?\u003c\/h3\u003e\u003cp\u003eNo. The vitamin K2 (MK-7) is derived from fermented chickpeas, not soy. The product is non-GMO.\u003c\/p\u003e\u003ch3\u003eIs it suitable for vegetarians?\u003c\/h3\u003e\u003cp\u003eThe vitamin D3 is sourced from lanolin (sheep’s wool), so it is not vegan. Vegetarians may consider it acceptable, but vegans should look for a plant-based D3 alternative.\u003c\/p\u003e","brand":"Dr. Mercola","offers":[{"title":"Default Title","offer_id":48358654148846,"sku":null,"price":101.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/1158\/7822\/files\/6145osvf_gL._AC_SL1500.jpg?v=1784596051","url":"https:\/\/vitamin4ca.com\/products\/dr-mercola-vitamins-adk-30-capsules-5000-iu-a-d3-180-mcg-k2-ca-b0cy5qwmg8","provider":"vitamin4ca","version":"1.0","type":"link"}
