I am at 3 grams a day and have no sides... when my ALA comes in I will be bumping it up to 4 grams a day. What may be the only factor as I stated earlier is your body won't be able to use iron efficiently. I am not exactly sure of the benefits from iron but I am sure someone on here does......
To sum it up Suspension, 2-3 grams a day should not hurt you.
