Forget amino acids or the jarrow formula. Order Dr. Schulze bowel detox kit, (herbdoc.com) and get started on it. Make sure your bowels are moving regularly, (at least once for every major meal) you can acheive this with the intestinal number one in the kit, note: do not use the #1 if you have any kind of bowel inflammation, IBS, Chrohns, Etd, go directly to #2 in that case. (follow the directions)
Once your moving regularly, use intestinal #2 as directed. If you have high levels of heavy metal toxicity you will likely need to repeat the clease 2 or 3 times. The clay and apple pectin will absorb and remove the nickel and any other heavy metals. JUST MAKE SURE YOUR BOWELS ARE MOVING REGULARLY or you will make yourself sick.
If you do not have a juicer, you will need to get one before even considering doing this cleanse. Go to herbdoc.com, there is a ton of free information to get you started. His company and products are the best, hands down. Anything else you do will be a waste of time and money.
