Designs for Health Vitamin D Supreme delivers a powerful combination of vitamin D3 (5000 IU), vitamin K1, vitamin K2 as MK-4, and geranylgeraniol (GG). This advanced formula works synergistically to help direct calcium where it belongs – your bones and teeth – while supporting overall cardiovascular wellness and immune balance.\u003c\/p\u003e\n\n\u003ch2\u003eKey Health Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBone Health:\u003c\/strong\u003e Vitamin D3 promotes calcium absorption from the gut, while vitamin K2 helps incorporate calcium into the bone matrix, contributing to bone strength and density.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeart Health:\u003c\/strong\u003e By activating matrix GLA protein (MGP), vitamin K2 helps maintain normal calcium balance in arteries, promoting arterial flexibility and cardiovascular wellness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmune Support:\u003c\/strong\u003e Vitamin D3 is known to modulate immune function and help maintain a balanced immune response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMood and Healthy Aging:\u003c\/strong\u003e Adequate vitamin D levels are associated with healthy mood and cognitive function.

However, osteocalcin must be carboxylated (activated) by vitamin K2 to effectively bind calcium to the bone matrix. Similarly, MGP, which helps prevent calcium deposition in arteries, is activated by vitamin K2. Without adequate K2, the calcium absorbed due to D3 may not be properly utilised, potentially compromising both bone density and vascular health. The MK-4 form of K2 used in this supplement is a short-chain menaquinone with a rapid turnover, ideal for supporting these daily activation processes.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Take Vitamin D3 and K2 Together?\u003c\/h2\u003e\n\u003cp\u003eVitamin D3 and vitamin K2 work as a team to manage calcium in the body. Vitamin D3 increases calcium absorption from the gut, but without sufficient K2, calcium may end up in soft tissues like arteries instead of bones. Vitamin K2 activates proteins that help direct calcium to where it is needed most – your bones and teeth – while helping maintain arterial flexibility. This partnership supports strong bones and cardiovascular health simultaneously.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Makes Designs for Health Vitamin D Supreme Special?\u003c\/h2\u003e\n\u003cp\u003eThis formula goes beyond standard D3+K2 supplements by including both vitamin K1 and K2 (as MK-4) plus geranylgeraniol. K1 is primarily involved in blood clotting, while K2 (MK-4) focuses on bone and cardiovascular health. The addition of GG – a compound naturally produced in the body but declining with age – further supports bone health and immune system balance. Each small, easy-to-swallow capsule provides 5000 IU of vitamin D3 and 2000 mcg of total vitamin K (as phytonadione and menaquinone-4), making it a comprehensive choice for those seeking advanced nutritional support.\u003c\/p\u003e\n\n\u003ch2\u003eWhat to Look For in a D3 + K2 Supplement\u003c\/h2\u003e\n\u003cp\u003eWhen choosing a D3 and K2 supplement, consider the dosage ratio, form of K2, and additional ingredients. Typical research-backed doses range from 1000–5000 IU of D3 and 45–100 mcg of K2 as MK-7, but MK-4 may require higher doses (1000–5000 mcg) due to its shorter half-life. This product uses 2000 mcg of MK-4 plus K1, which provides rapid and sustained activity. Look for supplements from reputable brands that undergo third-party testing for purity and potency. Designs for Health is the #1 practitioner supplement brand recommended by functional medicine professionals, reflecting its commitment to quality.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eCan I take this supplement if I am on blood thinners?\u003c\/h3\u003e\n\u003cp\u003eVitamin K can interfere with anticoagulant medications like warfarin.
