NatureGenX - ADK Vitamin A D K Dietary Supplement that supports bone structure, density and integrity; proper bone remodeling; calcium utilization; and cardiovascular function*. Vitamins A, D3, and K2 (as MK-7) Supports Calcium Absorption, improve bone growth, maintain Cardiovascular Health * Vitamin A supports the number and activity of osteoclast cells which break down bone tissue, an ongoing process of skeletal maintenance called bone remodeling.* Bone remodeling is a natural way the body removes old or weakened bone tissue in order to make room for new, stronger tissue.* This process is critical to fracture repair and retaining bone density.* Vitamin D3 (cholecalciferol) : It supports calcium absorption in the gut and helps maintain adequate serum calcium and phosphate concentrations to enable normal mineralization of bone.* Research shows that K2 partners with Vitamin D3 to inhibit the production of osteoclast cells (cells that break down bone) in order to help bone-building osteoblasts catch up to maintain a healthy balance.* Vitamin K2 is required for the activation of osteocalcin, a Vitamin K dependant protein that transports calcium from the blood to form a healthy bone matrix. Vitamin K2 not only supports the deposition of calcium into bone, it also has a regulatory effect on Vitamins A and D with regard to osteoclast and osteoblast activity.* Serving Size 1 Capsule a Day - All Natural - No Soy - No Dairy - No Nuts - No Artificial Flavors/Colors SEA MOSS JUST ONE METHYLATION PROTECT ADK 10 LETIN XT LIQUID VITAMIN D3 10,000 IU Buying Options Buying Options Buying Options Buying Options Add to Cart Buying Options Customer Reviews 4.4 out of 5 stars 104 4.5 out of 5 stars 365 4.4 out of 5 stars 64 4.7 out of 5 stars 426 3.7 out of 5 stars 1,014 4.3 out of 5 stars 802 Price — no data $33.96$33.96 — no data $33.96$33.96 $19.75$19.75 $14.36$14.36 Delivery Format Capsules Capsules Capsules Capsules Capsules Liquid Manufactured in a cGMP facility in the USA ✓ ✓ ✓ ✓ ✓ ✓
