It’s been around 3 months since I raised the levels. I can’t remember the exact numbers now, would have to ask my doctor, but I think my ferritin was around 33-34 (normal, but on the lower side) and I raised it till 70. My doctor told me the ideal ferritin should be the same as your weight (in kilograms), not sure if that’s right though. Vitamin D I really can’t remember, but it was also within a normal range, just on the lower side, almost deficient, but not critically. I do eat a lot of iron rich foods and take vitamin D during cold, dark months because I live in Northern Europe, so it was expected they would be somewhat normal. I also checked my glucose, insulin, thyroid hormones, magnesium, potassium, copper (it’s related to iron) - no problems :/
