When it comes to how many milligrams are in a capsule you should be looking for a 400mg serving. I been to a major store a saw a deal on two bottle of green coffee bean extract on sale for $10.00. But after taking a closer look, it was no deal at all. because the dosage per capsules was so low, that it would actually take 8 capsules just to equal 400mgs. But the bottle said to take only two capsules at a time. So if you follow the program to take three 400mg servings a day. These two bottle would last you only 8 days. LifeExtension is 400mg per serving and contains 90 servings per bottle. So it is a better value and you don't have to swallow as many pills.
Here is a good video explaining all the benefits of Life Extension brand green coffee extract.
I hope this information provided helps you to make a well informed choice when choosing a brand of Green Coffee Extract to purchase. I have found some good deals at www.puregreencoffeediet.com as well as a host of information and articles explaining how green coffee bean extract works with weight loss and better blood sugar level control.
