 Yeah, Actiflex, I think it's a great formulation, a joint and muscle formula. So it improves your joint health. It's a powerful anti-inflammatory product. So therefore, it's going to help support healthy cartilage and joints. So the cartilage is the covering at the end of the bone that glides another bone past it. Now, the joint itself is that area between those cartilaginous materials. And so joint fluid is very important.
