The formula is designed to provide the structural components needed for healthy bone strength and to support the complex processes involved in bone mineralization and maintenance. Key Features Aquamin® Mineralized Red Algae — a premium, trademarked source of calcium, magnesium, and over 72 trace minerals intended to support bone cell mineralization and density. 72 Trace Minerals for Better Absorption — trace elements may help improve the body’s use of calcium. Vegan Vitamin D3 sourced from lichen — supports calcium absorption from the digestive tract. Vegan Vitamin K2 sourced from natto — helps activate proteins that bind calcium into bone. Contains 12 Organic Fruits and Vegetables — to provide additional phytonutrients (brand claim). Vegan Approved Formula — suitable for plant-based diets. Benefits Supports Bone Growth & Strength: Calcium is essential for maintaining bone density and strength, and algae-derived calcium (Aquamin®) provides a natural, multi-mineral source that may support your skeleton. Enhances Calcium Absorption: Vitamin D3 helps the body absorb dietary calcium, which is vital for building and preserving bone tissue. Improves Calcium Utilization: Vitamin K2 plays a role in activating osteocalcin — a protein necessary for binding calcium into the bone matrix rather than soft tissues. Provides Trace Minerals: The mineralized red algae supplies over 72 trace minerals that may support bone and cellular function and enhance mineral uptake. May Support Joint Comfort: Aquamin® has been studied for benefits in joint comfort, including reducing NSAID use among osteoarthritis sufferers in some reports (though not FDA-evaluated). Heart & Arterial Health: Vitamin K2 also helps regulate calcium in arterial walls, which may support vascular elasticity and cardiovascular health.
