Acai berry supplements are in vogue these days, in the news, on TV, and of course on the Internet. There is a lot of publicity surrounding them, after all they've been endorsed by both TV personality Rachel Ray and Oprah, as a weight loss product, which means you need to exercise caution when you choose the right type of acai berry supplements.

Make sure the product you're considering actually includes acai berry. If there are other ingredients included such as green tea, caffeine, or a laxative, make sure you're aware of them. The ingredients have to be on the label, but they're not always listed on the company's website or they're hidden in the small print. Email the company or contact them through their website. If they don't get back with you, don't buy the product.

The free trial offer means the company provides you with a two week supply of their products. You can use them without paying the actual cost, just shipping and handling, which usually comes to a total of four or five dollars.

Once you receive the package use the supplement for enough time for you to understand the kind of effect it has on your body. After that you can make an informed decision on whether you would like to carry on with the same supplement or not.

If you do want to continue, do nothing and the supplement will continue to be shipped to you every month and automatically billed to your credit card. That's what you probably agreed to when you completed the online order form. Even if you didn't read the terms of service you agreed to them by ordering. So make sure you read the terms of service on any free offer or trial offer of any product you order.

Make sure you understand when the automatic shipping will begin, how much the billing will be and how often. Also be aware of what you need to do, and the time period you have, if you wish to cancel the billing. Some companies require that you email them or phone them by a certain time period to cancel, as they won't refund any billing when that time has past.

You can also get the desired acai berry supplements from the local health food store. It's not free but you can try out a small bottle to see if it's for you. Supplements are available on eBay as well. The problem is that if it's an individual offering the supplement you can't be sure the bottle or wrapping hasn't been tampered with.

Trying a free sample or risk free sample is a cost effective way of knowing whether acai berries will work for you. Know what the terms of service are, how you discontinue the billing, and how much the supplements will cost if they continue to be shipped.
