Fortunately, the dose is small and may be directed at the intruders before it is directed at you. It may be cysteine hydrochloride or simply free cysteine. Taking this supplement can give you side effects, perhaps due to its penetrating anti-parasite property. If you have serious side effects, reduce the dosage. Even if you reduce the dosage, do not take it longer than 3 weeks.
Most persons get no side effects.
Remember, animals that are being de-parasitized have similar symptoms. I have not yet found a way to counteract these symptoms, so it is wise to drink lots of water while taking it, take vitamin C and vitamin E, 400mg, one a day. Vitamin E will counteract the over-oxidation produced temporarily by the ozonated oil. Take it two hours or more after the ozonated oil to make sure there is no loss of the oil's potency. Usually, all side effects disappear in a few days, but in difficult cases they may last a week.
