“Can be combined Multi-Guard® Osteo Advance with Omega 3,6,9 and Collagen with Hyaluronic Acid?”
R/ Combining Multi-Guard® Osteo Advance with Omega 3,6,9 fatty acids is perfect. If you want to make another combination, it will depend a bit on what you wish, or if there is something rather than trying to prevent. But in principle it is a good choice.
To help repair the collagen and thus the entire body collagen matrix (ligaments, vessels, tendons … I understand your question may be due to joint issues) Colladeen® Derma plus (skin) and Colladeen® Maximum Strength (general).
In LAMBERTS® there is not any specific product containing hyaluronic acid. Collagen and elastine are cares by providing specific amino acids and substances involved in their synthesis as (glucosamine/chondroitin), as well as protective and restoratives substances as Colladeen.December, 2013
