Of course. Sometimes for certain substances they talk about toxicity in mcg or mg per kilogram of body weight, so the toxic amount would be double for a 200 pound man that it is for a 100 pound woman for example. Not all substances work like that though. For many things though, they seem to give a guideline based on a 150 pound person.
It depends on what kind you are using too as far as accumulation and toxicity right? I heard natural forms from Broccoli and so on are alot better, while L Selenomethionine can accumulate and become toxic. I have a book that says thats the cheapest form or one of them and the most toxic, is that true? I can't use alot of Selenium at all, even a half or 1/4 of a pill will make me wake up early after a few days or weeks use and feel horrible, I get bad anxiety and mind racing and so on. Any reason why? Kelp can do this too in higher dosages, both are not kind to me.


In Sanskrit, tulsi means literally "the incomparable one" and has been revered since ancient times. Tulsi, the holy basil, is said to have grown at the site of Christ’s crucifixion and is associated with St. Basil’s feast.
