Hello! I have some pregnant does. It is there first time including mine. I was wondering if the selenium gels and copper are needed? Or if I can just supplement from other things that naturally contain these things like Selenium---alfalfa, kelp, slippery elm, raspberry leaves, milk thistle, catnip, black oil sunflower seeds, black strap molasses. Copper---black strap molasses, hops, sesame, sunflower and other squash seeds, dried basil, oregnano, marjoram, parsley and thyme. Thoughts? Id rather go natural then injections or oral gels.
