Vitamins do not contradict Robert’s elixirs, however, I don’t like that under “other ingredients” the first one in this one is cane sugar. They should not have sugar in them at all. It will feed the pathogenic bacteria (candida) in his gut which is bad. He will need a good multivitamin but I wait in the program until the gut is healed a bit, so parasites won’t use them as food. I have a very high quality product that I suggest in the program in module 3. I would stick to the order of the videos for best results, and be sure to only add one new supplement of any kind every 1-3 days. Remember to muscle test prior.
