In 2004, Canada began regulating natural medicines as a category of products separate from foods or drugs. These products are officially recognized as "Natural Health Products." These products include vitamins, minerals, herbal preparations, homeopathic products, probiotics, fatty acids, amino acids, and other naturally derived supplements.
In order to be marketed in Canada, natural health products must be licensed. In order to be licensed in Canada, manufacturers must submit applications to Health Canada including information about uses, formulation, dosing, safety, and efficacy.
Products can be licensed based on several criteria. Some products are licensed based on historical or traditional uses. For example, if an herbal product has a history of traditional use, then that product may be acceptable for licensure. In this case, no reliable scientific evidence is required for approval.
For products with non-traditional uses, some level of scientific evidence may be required to support claimed uses. However, a high level of evidence is not necessarily required. Acceptable sources of evidence include at least one well-designed, randomized, controlled trial; well-designed, non-randomized trials; cohort and case control studies; or expert opinion reports.
Finished products licensed by Health Canada must be manufactured according to Good Manufacturing Practices (GMPs) as outlined by Health Canada.

Below is general information about the safety of the known ingredients contained in the product Gammadyn S. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used topically and appropriately, short-term. Topical products containing sulfur in concentrations up to 10% have been used safely in clinical research for up to 8 weeks (27846,27847,88107,88112,88123,88124,98205,98207,100735). There is insufficient reliable information available about the safety of using sulfur orally.
CHILDREN: POSSIBLY SAFE
when used topically and appropriately, short-term.
Topical products containing sulfur in concentrations up to 6% have been used safely when applied nightly in children and adolescents for up to 6 nights (27846,27847). In infants, topical products containing sulfur in concentrations up to 2% have been safely applied for 3 hours daily for up to 6 days (27847).
PREGNANCY AND LACTATION: POSSIBLY SAFE
when applied topically and appropriately, short-term.
Topical products containing sulfur in concentrations up to 6% have been safely applied nightly for up to 6 nights (27846,27847). There is insufficient reliable information available about the safety of sulfur when used orally; avoid using.

Below is general information about the adverse effects of the known ingredients contained in the product Gammadyn S. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General ...Topically, sulfur is generally well tolerated when used in concentrations of up to 10%. Adverse effects include skin dryness, irritation, and pruritus (27846,88112,88120,88121,88126). Orally, sulfur has been reported to cause diarrhea and metabolic acidosis (27845).
Dermatologic ...Topically, application of sulfur preparations can cause dryness, leading to local irritation and pruritus in up to 28% of patients (27846,88112,88120,88121,88126).
Gastrointestinal ...Orally, sulfur is converted to sulfide in the gastrointestinal tract, causing intestinal irritation which can lead to diarrhea (27845).
Renal ...There is one case report of metabolic acidosis occurring in a 57-year-old woman who had consumed approximately 250 grams of flowers of sulfur, a form of sulfur prepared by sublimation, over a 6-day period (27845). Underlying conditions, including diabetes and renal failure, may have contributed to the acidosis. Sulfur is converted to sulfide by colonic bacteria and then to sulfate in various tissues, generating hydrogen ions which can lead to acidosis when clearance mechanisms are overwhelmed (27845).
