Ramona,
Firstly, I love your name!! OK, MSM answers. You sent me scrambling for my data base as, because this is anti-cancerous, it is banned for use in Australia. Long story trust me!! The following is a "cut and copy" from the latest data base on MSM.

Dosage Recommendations

General Therapeutic Dosage

The standard dosage of supplemental oral MSM is 250 - 1,500 mg per day:

- Clinical trials have reported improvement of a diverse range of health problems with the administration of daily doses of 250 - 750 mg of MSM.

Digestive System

Clinical studies using supplemental MSM for the prevention and treatment of adult Constipation have suggested that maximum therapeutic effects are obtained with dosages ranging from 100 - 500 mg per day.

The suggested dosage of supplemental MSM for the treatment of Hyperchlorrhydria and Heartburn is 3,000 mg per day.

Toxic Dosage

Doses of up to 30,000 mg (30 grams) of MSM have been used on a daily basis without adverse effects occurring.

“Waiting Period”

Most people who use supplemental MSM do not notice any therapeutic effects until they have used MSM on a daily basis for several days. Some people do not experience therapeutic effects until MSM has been used daily for several weeks.
