Youtheory Bone Collagen + D3 & K2 aims to support a wide array of health aspects, particularly focusing on bone, heart, joint, and beauty (skin, hair, nails). The product contains 180mcg of Vitamin K2 (Menaquinone-7), 200mg of Calcium (Aquamin), and 2500mg of hydrolyzed Collagen. From a nutritional and scientific standpoint, this combination is highly strategic. Vitamin K2 (MK-7) is crucial for directing calcium to the bones and preventing its accumulation in arteries, directly supporting both bone and cardiovascular health. Aquamin calcium, derived from red marine algae, is noted for its high bioavailability and includes other trace minerals beneficial for bone health. Hydrolyzed collagen, being a highly absorbable form, provides the foundational proteins for connective tissues, joints, skin, hair, and nails. Online reviews and nutritionist perspectives often highlight the importance of combining K2 with calcium for optimal bone and heart health, and collagen's benefits for structural integrity are well-documented. The dosage of K2 is particularly strong, while the calcium and collagen dosages are moderate but effective, designed to supplement dietary intake rather than provide full daily requirements. The price per serving of $0.66 is reasonable for the quality and combination of ingredients offered.
