I do not know the Specialty. Please help. I am concerned about SULFUR Levels, the Cystathionine beta synthase (CBS) Mutation Gene, and Amino Acids. Several years ago, I took 3,000 micrograms of Biotin for about 6 months for my hair, nails, and skin. Gradually, I developed a sore throat that would not go away. From time to time, I had headaches, felt light-headed, congested, and fatigued. These symptoms occurred after I ate certain foods, either shortly after, or 4 to 8 hours later. The foods were cruciferous vegetables, dairy products, wine, some bread, onions, garlic, and coffee (decaf or regular). I had never had these problems before. I also developed a histamine problem (runny nose) with kiwi, apples, and grapefruit. I stopped eating many of these foods. I stopped taking Biotin. I ate rice and barley, and some animal proteins--not foods that caused symptoms.
I took an allergy test. No allergies to these foods. Allergist prescribed Allegra-D and Nasonex for Allergic Rhinitis. About 6 weeks later, I was all right. The Allergist did not know why I had sore throat or other symptoms regarding foods. Still, I believe he helped me. The Allergist is now retired. I could eat all the above foods again.
Early in 2014, I took N-Acetyl-Cysteine (NAC) 600 mg twice a day for about 4 to 6 months to boost immune system. Dosage called for 1 to 4 capsules daily. I took 2. Same symptoms developed gradually, ONLY after eating the above foods. Again, I developed headaches, light-headedness, congestion, and runny nose. I took Allegra-D (now generic). Another Allergist prescribed Nasonex. If I eat these foods again, the symptoms continue.
Initially, I had looked up both Biotin and NAC for side effects. Both appeared to be common supplements and highly praised. I looked up NAC again. NAC is SULFUR-rich--and so are Biotin, B1, and some other supplements, along with CRUCIFEROUS Vegetables and other foods. I then found a reference to Cystathionine beta Synthase (CBS), a mutation gene. I stopped taking NAC, and again am on a diet without problem-causing foods. I am concerned that I may now have excessive SULFER Levels, and also CBS. Daily, I take Vitamin D (2000 IU); Magnesium Glycinate, 360 mg; and Calcium Carbonate, 600 mg.
Can I be tested for SULFUR Levels (L-Cysteine, Plasma Blood Test?) and the CBS Mutation Gene? Are there any Vitamins or Minerals that bind to Sulfur to remove excess amounts from the Body. Thank you very much. Angelina Sauceda
