@corina Welcome to connect . We try to help with our experience that you may have also. I want to warn you if your allergic to sulfa don't take glucosamine for arthritis . It is from shellfish, unless you can get the vegetarian kind .

@corina Yes I was surprised also but glucosomine sulfate is derived from crabs and is high in sulfate

Hi @corina and @lioness, Sulfa, sulfites, sulfates - 3 words that are very similar but not the same can be very confusing. I had to look them up myself to remember which is what.

Sulfates are salts of sulfuric acid and are present in many medicines, supplements, and personal care products – they are not the same thing as sulfites or sulfa drugs.

@lioness, sulfa drugs are not the same as glucosamine sulfate or sulfate. The following articles help clarify:

- Differentiating Sulfur Compounds: Sulfa Drugs, Glucosamine Sulfate, Sulfur, and Sulfiting Agents http://www.itmonline.org/arts/sulfa.htm
- Definitions from American Academy of Allergy, Asthma & Immunology https://www.aaaai.org/conditions-and-treatments/conditions-dictionary/sulfite-sulfa
- Sulfa, Sulfur, Sulfate, Sulfite: Which Causes an Allergy? from Medscape https://www.medscape.com/viewarticle/870347

@colleenyoung - Thank you for clarifying this. I have a sulfa drug allergy after many years of taking it. Not one Dr gave me any restrictions, as a matter of fact I had raw tuna last night for dinner. For me my pharmacist is an encyclopedia of knowledge when it comes to drugs and suppliments! @corina does this help?

@colleenyoung Thanks for the clarification . I am allergic to shellfish, shrimp especially and was always told not to take glucosomine I assumed it was the sulfate so glad to know the difference . Sorry corina I learned something today also .
