California Gold Nutrition's Bone Boost is a robust supplement designed to support various aspects of health, with a strong emphasis on bone wellness. It provides multiple highly bioavailable forms of Calcium (Fructoborate, Citrate Malate, Bisglycinate, Ascorbate) and Magnesium (Malate), ensuring good absorption. The inclusion of Vitamin D3 is critical for calcium absorption, though at 400 IU (10mcg), it's on the lower side compared to some recommendations for optimal bone health, particularly if sun exposure is limited. However, the presence of 90mcg of Vitamin K2 as Menaquinone-7 (MK-7) is excellent, as it plays a vital role in directing calcium to the bones and preventing its accumulation in arteries, contributing significantly to both bone and cardiovascular health. Key trace minerals like Boron, Silica from Horsetail extract, Zinc, Copper, and Manganese are included in chelated forms, enhancing their absorption and supporting bone matrix formation and overall mineral balance. The addition of MBP (Milk Basic Protein) is a noteworthy feature, with research suggesting its role in promoting bone formation and inhibiting bone resorption. Vitamin C is also present, essential for collagen synthesis, which is integral to bone, joint, and skin health. While the product lists a wide array of goals, its ingredient profile is most strongly aligned with bone health, cardiovascular support, and general mineral replenishment. Online reviews generally praise its effectiveness for bone density and ease of digestion, attributing noticeable improvements in health markers. However, consumers should be mindful of the multiple tablets required per serving (2 tablets for 600mg Calcium) and ensure their total daily Vitamin D intake from all sources is adequate.
