Toco-8 is a very complete product of Vitamin E analogues. Vitamin E is a fat soluble vitamin (make sure you're taking it with a healthy fat to enhance absorbtion), so it's stored within the body (unlike water soluble vitamins that used as needed at the time, and then are excreted via the renal (kidney) pathway. This means that over time, you will build up a healthy supply that the body can use as needed to carry our its homeostatic functioning.
In answer to your question about dosing: Our recommended dosing guideline (1 scoop daily) will help you achieve that goal even at your size. You could take it 2 x daily for a short time, but I definitely don't recommend that protocol be followed for any significant length of time. Toco-8 is the type of product that will produce better results the longer you take it.
Too much of a fat soluble vitamin has the potential for toxic effect, however you would need to take a HUGE amounts to ever get near that level.
Remember: more is not always better, and slow and steady wins the race. If there is anything else I can help you with, just let me know.
