Your body won't be able to utilize all of the nutrients at once, so split them up. This is what I do so I don't overstim to late:
7:30 AM Recreate first thing in the morning
CLA with breakfast
Green Tea Extract Mid Morning
12 PM Recreate right before I go to work
CLA with lunch
Green Tea Extract mid afternoon usually after my second biggest meal. Also, taking the Green Tea Extract at that time gives me a little caffeine boost to keep me going at work.
CLA with casein shake before bed.
I obviously eat a lot more smaller meals than most to keep up with how I roll with my schedule and not overeat at one particular meal of the day to make up for calories. But that's how I like to roll. If that's too hard to keep up with then do CLA and Green Tea Extract during 2 of your biggest meals earlier during the day. Try to avoid caffeine with dinner or anything like that 6-8 hours before bed. If you aren't stim sensitive, 4-6 hours will be fine.
To answer your second question: run 1 gram(1,000 mg's) to 2 grams of Green Tea Extract a day. So, if you have 500 mg tablets, then do one mid-morning or breakfast and then the second one with lunch or mid-afternoon. I'm personally thinking of going against the grain around here with the CLA consumption being 3-4 grams a day instead of the massive 6-8 a day. I read up some studies that report that 3-4 grams was just as effective(and considered safer) as 6-8 grams. This should help with money, too. Sorry, I don't like spending all that much money on supplements if I know that I could do something to not burn through them so quickly. I like supplements, but I don't like supplements that much.
