One standout the massive line of diet fads is the acai berry.  The little purple berry that hails from the far-flung Amazon rainforests has traveled far, appearing even on Oprah. 

Like every diet fad comes accusations of false claims, scams and overly zealous testimonials. So finding straight answers on acai berry supplements is more likely to find you a headache than a miracle food. 

The key is finding the purple acai berry, not the less-helpful white acai berry.  The purple berry, like coffee or a dark tea, is colored with antioxidants, but is -- of course -- more expensive.  But even if you've found a good berry, the diet might not be right for you.  Some users say the potent berry upsets their stomachs and actually makes them feel worse. Others, however, say it's the greatest supplement they can find -- boosting energy, metabolism and just making them feel good.

The best way to find out whether or not acai berries will work for you is to just try it.  It's easy to find a free trial offer online, and as long as you cancel your subscription by the time the free trial ends, you'll only need the cost of shipping for what can be an extremely expensive supplement ($4 to $6 a day).

The acai berry diet fad is here and will likely be here for a long time, so it's not hard to find the big names in the business.  While you may be tempted to search for exotic dried berries or hard-to-find small providers, it's not always the best way.  Reputed companies have become so for a reason, they have found a tried-and-true method to their supplements and because of their size, they can slash costs.

Acai berry power 500, for example, has a free acai berry offer, and has become extremely popular because of it.  But finding the best deal can take time.  If one doesn't work, try another free offer, and if the acai berry diet just isn't your thing, make sure to cancel your subscription before you're charged full price.
