We should wait for the real people who know all about it.
I never heard of that supplement, but I also haven't use google to search for it. Some thal minor patients do take something iron supplements (is that right). Though you should better let your iron panel test. Only that you may know of you can take this. What's your hgb? Do you know that? We have some members from Singapore and they should advice you a doctor.
My post doesn't really help you, but better advice is on this way. Maybe after the weekend, but good advice is coming!
Best wishes,

p.s. I dont have thal, but the (other) rare anemia called pyruvate kinase deficiency. Different cause, same treatment.
