Even though sulfur is a crucial nutrient, especially because of its vital role in maintaining the health and integrity of our cellular system, a recommended minimum daily requirement has not been established.
Methylsulfonylmethane (MSM) is an organic sulfur compound found in many foods. The Food and Drug Administration has suggested a daily intake of 2,000 to 2,500 micrograms of MSM, while the National Academies of Sciences, Engineering, and Medicine believes that just 0.2 to 1.5 grams per day is sufficient. There is a common perception among the medical community that most people obtain ample amounts (from 3 to 6 grams) of dietary sulfur on a daily basis.
On the other hand, the amount of MSM normally found in food products is likely to be reduced if they are consumed in a processed form (not fresh) and/or have been grown in farm soil that has been treated with chemical fertilizers.
