Osteo Bi-flex is a joint formula that provides the clinically proven dose of glucosamine (1500 mg) and chondroitin (about 1400 mg) in just 2 tablets. That alone will do wonders for all but the most severe joint problems. But there are a few more additions to the formula. Many customer's won't be familiar with the 5-LOXIN ingredient in Osteo Bi-flex. This is a patented derivative of boswellic acid, derived from the boswellia herb. Boswellia has a long history of use in herbal medicine for trauma, pain and swelling, especially of musculoskeletal origin. Osteo Bi-flex provides 100 mg of 5-LOXIN in each dose.Calling a product like this "Osteo Bi-flex" might be misleading to some customers, since, although it's a great joint formula, it isn't really a bone formula (has no calcium or magnesium). But the formula also includes trace mineral bone health factors like boron and manganese, which many multis and even some bone formulas lack. So while Osteo Bi-flex provides some support for bone health, it's strength is it's support for joint health and inflammation control.
