Do you take a Multivitamin and mineral supplement...a generic, no-iron or senior version is good to fill in any possible nutrient deficiencies. If you don't eat foods with Omega-3s, then supplementing with fish oil is recommended. I also add magnesium and iodine from kelp (I don't use iodized salt). K2 is found in animal-based products like meat and chicken, so believe my diet is providing enough.
