Advanced Bionutritionals is marketing a supplement, Ultimate Bone Support, which focuses on improving bone density. It has 4 mg silicon from Horsetail herb, Equisetum arvense, which they say acts as a switch to turn on the bone-building process; 400 mg L-Lysine, which is a component of all forms of collagen, but also blocks the enzymes that break down collagen and acts as a glue to connect collagen fibers together; 500 mg strontium citrate, which has been shown to increase bone density and reduce risk of fractures; 2 mg Boron aspartate-citrate, which has been shown to have multiple benefits on bone strength, bone healing, preservation of bone-building osteoblasts, and countering bone loss from low hormone levels in women; 300 mg Hops (Humulus lupulus L.) extract, min. 30% alpha acids; also vitamin D3, vitamin K2, zinc, copper, and manganese. Is this supplement effective as a stand-alone nutraceutical for maintaining bone health with aging?

This will, indeed, have a benefit for adding structural integrity and preventing degradation from aging used on its own. This will be modest, but the ingredients are helping from multiple vantage points to keep normal function going and counter the declines with aging in multiple physiologic pathways and systems.
