I've heard some people do that and have success. I know that one of my nurses opened a cap of nystatin and began by putting a bit of powder on her tongue for like 5 days and gradually increased

herbs that are easier on the adrenals such as nettle leaf which also builds up the adrenals, amla berry also.

should head over to HV's forum the truth in medicine on here, wealth of info.

what supplements is it your having problems with?

I think that is a good idea.

Are you drinking water with lemon? I sometimes throw an entire lemon through the juicer, if I'm feeling particularly thirsty for cleansing and bit C. Also, what about nutritional yeast? It is full of b vitamins. I like to add it to my chicken broth.

I will cook chicken bones all day and then take the broth and add a scoop of butter, a big pinch of Sea Salt and the tablespoon full of nutritional yeast. My body feels very happy when I do this. I don't know if it has enough b vitamins, but I'm sure that it will help.

Muscle testing is an option.

The body responds much better to natural food supplements than chemical types. Look at the foods that have what you need in them and also use digestive enzymes to extract the most out of them.

I also have many sensitivities to supplements, foods, EMF waves, etc.
What has been helpful for me is that I found an excellent RN who owned her own practice and is a certified NAET practitioner as well as certified Ondamed Practitioner. She also had excellent recommendations from others in our local community.
I called and spoke with her several times before beginning with her and when I felt my body was strong enough to begin treatments with her is when I began.
You can google NAET and find a list of practitioners.
What is the idea behind this is that we can pour supplements into our bodies all day long YET if our body cannot recognize, utilize, process and eliminate the nutrients and supplements then it does not help. NAET treatments also help to decrease toxins, strengthens the immune system and helps energy levels as well as other things.
I took NAET treatments once a month during the time of my monthly cycle when my body was the strongest. In the beginning a surrogate was used to do both the testing and the treatments for me. Then as I got stronger, the treatment portion of the session was done on me but always the testing was done thru a surrogate. This is all in the genre of energy medicine. I do caution though to be VERY sure you have a well reputed, competent practitioner doing the treatments.
Also, you can bring in your supplements to them and they can test what your body is compatible with or what within the supplement contents is you are sensitive to. Unfortunately, this RN's husband recently passed away and she has decided now to close her practice for now. This is a great loss to our community as she has a spirit of excellence and was very gifted.
