Yes, there is sulfur in the ReAline, and that is a good thing! From the directions for ReAline on www.rnareset.com/collections/frontpage/products/realine-capsules :
"The amino acids in ReAline are sulfur-based: l-methionine and l-taurine. ReAline also contains 4 methylated B vitamins: 5-Methyltetrahydrofolic Acid, Methylcobalamine-B12, Riboflavin-5 Phosphate (B2), Pyridoxal-5 Phosphate (B6) and Betaine HCL (trimethylglycine). All of these nutrients are important for the proper metabolism of methionine...
Even though sulfur is the third most common mineral in the body (after calcium and phosphorous), sulfur’s importance is not commonly acknowledged. However, it is a key component in balanced DNA and protein replication. Sulfur is important for the production of mucous and detoxification. Obtaining sulfur from methionine and taurine is more metabolically sound than taking sulfur supplements because the body can gauge how much it requires in any given moment."
