My RE recommended it, but technically he recommended I just buy the key ingredient, myo inositol, and take that. It's much less expensive that way.
113 days (at 2000 mg/day) of inositol powder, $14.72
BTW my RE specifically recommended the Jarrow brand.
Overall he recommended it for egg health, and had me start it 4 months before my first IVF retrieval cycle.
