Results vary depending on the product and the individual. Many factors such as your lifestyle, weight, gender and eating habits will play a significant role in how a supplement works and what dosing you should take. Some supplements start working shortly after use, while others can take a few weeks before you see real results. Your best bet is to take a product consistently, as suggested, for a period of time to let your body take in the beneficial nutrients.
