MERCANA is recommended as a dietary Supplement to the diet as an additional source of non-denatured collagen (natural) type II (UC-IITM)in order to normalize the functional state of the joints, in particular during exercise. Helps reduce joint stiffness, improve their mobility and flexibility. Studies have found1, 2, 3 that taking 40 mg UC-IITM capsules daily can help alleviate joint discomfort, as well as restore healthy function and flexibility. Also, research2 found that daily intake of capsules with 40 mg of UC-IITM for 90 days in certain conditions (for example, requiring the restoration of cartilage) can lead to more significant changes in indicators than when using a complex of glucosamine (1500 mg / day) and chondroitin (1200 mg / day). 1Lugo JP et al.
