No. If you’ve been on the diet for more than 6 months are are unable to reintroduce foods, most likely something else is going on. Mold, bacteria, virus, environment. Something else is bothering you or has caused a change in your immune system. If you are on the Lion Diet, and you test and have a low vitamin, supplement via IV. After 5 years on the diet with no organs I had low folate, with no symptoms of low folate, and I supplemented a bit anyway. It can be a risk for pregnant women and this can be mitigated by supplementation. Some people eat liver for folate which is fine but I’ve also seen people get vitamin A toxicity and develop scurvy after excessive organ supplementation. It’s a good idea to keep an eye on your vitamins, and if you’re deficient you can get vitamin IV’s to boost yourself up. This diet should take care of all your vitamins, but most people are deficient and getting back to baseline by having a few IV’s isn’t a bad idea. Be careful with supplementing pills – many of them can cause insomnia for sensitive people and other reactions which is why we’re recommending vitamin IV’s instead.
