Are supplements safe for people with sulfa allergies?
Many people who are allergic to sulfa drugs mistakenly assume that sulfa and sulfur are related. Sulfa is an abbreviated name for specific antibiotics called sulfonamides. A person who is allergic to these medications should not use them.
Sulfur, on the other hand, is an essential mineral found in nearly all proteins, vitamin B1, and multiple amino acids. It is not possible to be allergic to sulfur because the body cannot function properly without it.
Sulfate is simply a combination of the elements sulfur and oxygen and is naturally present in relatively high concentrations in human blood.
To summarize: the USANA products do not contain sulfa drugs. Someone with a sulfa allergy can safely take all of USANA’s supplements.
