International Unit (IU) is a unit of measurement used widely to quantify hormones, vitamins, blood products and several medications. It refers to the mass or volume of a substance but varies depending on the substance which is being measured and its biological activity.
Regarding Vitamin D, 1 microgram (μg) of vitamin D is equivalent to 40IU. Since 6 oz of baked salmon contains 23 μg of vitamin D, Andy's vitamin D intake will be 920IU (23 μg * 40IU = 920IU).
It's a type of drug, I'm pretty sure it's related to ecstacy in some way. Please do not do drugs, they're very harmful to not only you and your body but the people surrounding you, stay safe!
Its okay because I have depression also but something my counselor told me is not to think about it and think positive because its not good to think negative and also always take a breather but if you are in a bad mood then listen to music or draw or sing that what always help me and i bet it will help you too. :)
