I was able to be desensitized by my practitioner. He used a combination of Skasys, which created my own homeopathic remedy, that I took for a couple weeks. Then I was able to take the necessary supplement. The best part was that the desensitization held. I didn't need to keep taking a homeopathic.
I realize this is not an option for many people. Just sharing what worked for me.
I would say however, that if you are reacting to a supplement, listen to your body and don't take it until you are stronger. Continue listening....it's a process that takes time..... Intuitive eating.....
In a perfect world with perfect soil and no food supply manipulation and tampering, we wouldn't have to take these darn supplements! But in the meantime.....
