8000 mg = 8 grams
You’re absolutely right. I misread the label and should have known better. I wonder what an “international unit” consists of and how it relates to milligrams/micrograms.
The Body generates about 20,000+ IUs when bare backed exposure to the sun for 30 minutes, so as long as you are under that amount I would bet you do not have a risk of over dose.
With regards to vitamins, it depends on the vitamin. I've seen conversion charts and the conversion for each vitamin was different.
