The instructions for taking BioLean Free are on the box, and are easy-to-follow.
In brief, here is how you take BioLean Free. Each dose should be taken with low-calorie food. The usual dose is 4 tablets, which may be taken all at once in the mid-morning, or may be split (for instance, take 3 tablets in the morning and 1 in the afternoon). You may want to split the dose if you find your cravings or hunger are returning in the afternoon, as taking the fourth pill later in the day can help extend the effects.
Some people do not need all four tablets each day - try taking 2 or 3 tablets and see if that is enough to help control your cravings and appetite and help you lose weight. Add another tablet to your daily regimen if needed.
