Dear Kunal,
The most important thing that your friend can do at this time is to maintain good hemoglobin levels and low iron levels. This requires adherence to a good transfusion regimine, keeping hemoglobin level above 95 at all times, and keeping iron levels as though as possible - preferably below 1000 (the lower the better). We can help her in selecting a good chelator and chelation schedule.
We also recommend many supplements along with a good diet, rich in plant food sources. We recommend IP6, L-carnitine, vitamin D, vitamin e, zinc, calcium and magnesium as well as others to maintain good health. Drinking tea with meals is also very helpful
The comprehensive clinic in Oakland, Dr. Vichinisky is wonderful and would give you the best information.
