Review: Strong Option for Those Seeking to Enhance Bone Strength - Sometimes, I run across a product that feels like it's more of a work in progress. That's kind of my experience with NuBest's Bone Xtra. This is described as a premium supplement offering plant calcium, Vitamin D3 and K2, Magnesium, Vitamin C, Phosphorus, and Zinc. This came with two bottles. Each bottle is a 1-month supply and contains 120 vegetarian capsules. The capsules are a bit larger at right about 1" and I did have some difficulty with swallowing them. These are formulated and distributed by NuBest, a Wyoming-based company. I regularly take Vitamin D-3 and it's prescribed by my physician due to a deficiency. I've found the D-3 and K2 option to work very nicely. However, I'm not completely sold on the mix here and I've found myself reading a lot between the supplements I take to make sure I'm getting a sufficient amount and also not getting too much. These seem to be pretty amazing in terms of helping with bone strength and calcium absorption, though I almost wish the product were simplified rather than including so much. This is more of a premium product and I think it will be fine for those who are really focused on bone health. This has everything you'd need, but if on other supplements it would likely be a good idea to just make sure dosages match up. I doubt this will land in my regular wellness regimen, however, should I need to focus on my bone health in the future I'll probably revisit. ## Features - Algae-Sourced Calcium: Bone Xtra features plant Calcium derived from Aquamin Marine Algae, sustainably sourced seaweed minerals from the pure waters off the coasts of Iceland.
