I am a diabetic who was taking 1000 mg of Metformin a day for the past 2 years. 30 days ago I started taking 1 tsp of the Medicinal mushroom powder twice a day and stopped taking metformin altogether. My daily blood sugar has remained exactly the same as before with my A1C remaining at 6.8 In conclusion, I have been able to replace 1000 mg of Metformin with 2 tsp of the Medicinal Mushroom Powder per day This is amazing.
