Hey, Dionne!
Last I remember, you were 16, right? I would check with your physician about the MSM. Generally, with most supplements, you can take 3/4 of the adult dosage. The question with the MSM is whether it is really appropriate for you AT THIS TIME. I think your physician could speak to this concerning your anemia and the digestive problems. By the way, the MSM is supposed to help with digestion. Please check with your doc!
Otherwise, what did you have in mind? Have you noticed anything in terms of luster, softening, shine in your hair since taking the essential fatty acids (e.g., flaxseed oil, etc.)?
Much Love to you,
Jade
