Actually I would purchase one in an amount that could be used up in 3 months because they can become “old” with exposure to oxygen and light. My bottle of Nature’s Logic sardine oil suggests that. You would need to look at the dosages for the glucosamine and chondroitin per serving of oil to compare it to some other plain supplements and see if there would be enough. You can also alternate types of fish oils instead of using just one type. Right now I’m using krill and sardine oils.
