I have just been looking at some of the top-selling weight loss pills on Amazon, and it is clear that garcinia cambogia and green coffee bean extract supplements are still hugely popular with dieters right now in April 2014.

Garcinia cambogia supplements in particular are really selling well right now, and it was interesting to see that you can now buy supplements that contain 75% Hydroxycitric acid (HCA), which is the key ingredient that helps to boost the metabolism, suppress the appetite and block the formation of fat.

Experts recommend that you should look for pills containing at least 50% HCA when you buy garcinia cambogia pills, and those containing 60% HCA have always been considered to be maximum strength.

So the fact that you can now buy supplements that contain 75% Hydroxycitric acid suggests that these are extremely powerful.

There are two super-strength supplements in particular that are proving popular with customers at the moment.

The first is this garcinia cambogia supplement from Abundant Health, which obviously contains 75% HCA, and unlike many other products, doesn’t contain any calcium, or indeed any kind of fillers, binders or artificial ingredients.

You just need to take 2 of these pills twice per day 30-60 minutes before meals in order to help suppress your appetite, block the formation of fat and hopefully start losing a few pounds.

Plus if you fail to lose any weight whilst taking these supplements, there is a full 30-day money back guarantee available. Therefore you have nothing to lose by giving this product a try.

The second maximum strength supplement that is proving popular with dieters is this supplement from Island Vibrance.

This is very similar in that it contains 75% HCA, and is made from safe, natural ingredients with no fillers or binders. Like the product above, it also contains no calcium, which some say limits the effectiveness of these garcinia cambogia supplements.

The key difference between this product and the product above is that this one comes with a really generous 365-day money-back guarantee in case it fails to deliver results, which is almost unheard of in the weight loss industry.

So these are two safe and effective high-strength products that you might want to consider buying if you are currently struggling to lose weight because they can both help boost your metabolism and promote fat-burning, whilst also helping to suppress your appetite and block the formation of fat.
