My doctor, an ND, sold me these and said she seldom gets patients in for acute care once they have them. She said she was putting herself out of business. She started me at a specific dosage and schedule, then had me taper off until I was off them.
When I take them at the first signs of illness, I can often get above it in a matter of hours or days if I rest and get off the junk food. I also like to drink green vegies blended in organic vegetable juice or lemon juice in water. Lemon juice in water was part of her regiment for me.
I don't like to be without these. I have been using them to heal and prevent illness for about three years now. My doctor used these, along with other supplements, for liver support. For the first time in years, I had normal liver enzymes at the next test. She told me to use the Priority One Bio Vegetarian at the first signs of illness and said it is effective for viruses, bacteria, and even parasites. I'm not a doctor, so I can't say that it is right for every illness. Ask your health care person if they are right for you and at what dosage.
