Common questions we came across whilst researching our osteo biflex review
The vitamin blend (Vitamin C, Manganese & Sodium) in Osteo bi flex is a bit of a failure, we'd typically expect to see vitamin D in a joint supplement as it's a common deficiency (nearly half of all Americans) and a lack of it causes joint pain. The vitamins included will help, but far less than a vitamin d supplement would.
Glucosamine HCL is both one of the most effective ingredients in Osteo bi flex and the one that causes the most problems. Meta analysis of multiple studies suggest that it is beneficial for a subset of people [1], but does not work for everyone. And to top it off side effects we're present in many cases, most mild, but there were some severe ones as we have reffered to several times throughout our Osteo bi flex review.
Boswellia is marked as an effective anti inflammatory [2] it's included in most of the best joint supplements, and it's well tolerated across the board, Osteo bi flex get the dosage right, no complaints here.
Chrondroitin/MSM these are good ingredients, but the Chrondroitin has a similar effect to the glucosamine, and it makes it a bit redundant when you already have so much glucosamine. The other catch is we'd have liked to have seen a higher dosage as 275mg of the two combined is a little low if they're going to be included.
