But before you go to these sections, now, for starters, we would like to convey to you some general and very important information about products that are food supplements.

In our opinion, there are several important features that a high quality food supplement should have.

1. Firstly, we believe that a good food supplement should be produced by a reputable manufacturing company with many years of experience in the production of food supplements. And it should be a production company located in a country within the European Union, the USA or Japan, because production facilities in these countries provide for compliance with the highest quality standards of production. Production plants in these countries strictly follow the appropriate production, control and quality assurance procedures as defined by such systems as: GMP - Good Manufacturing Practice; GHP - Good Hygienic Practice; HACCP - system Hazard Analysis and Critical Control Points. Production plants in these countries also have the appropriate ISO quality certificates.

Slimvena™ is a food supplement that has been produced for Vellapharma Ltd by a reputable and experienced manufacturing company G&G Food Supplies Ltd, located in the England and operating since 1987. G&G Food Supplies has extensive experience in the production of food supplements.

2. Secondly, we believe that a good food supplement should contain only ingredients not genetically modified (so-called Non-GMO) produced by European, American and Japanese producers, because it guarantees the right quality of these ingredients. And best when these ingredients are branded products, because the branded ingredients are components of the highest quality.

Slimvena™ contains two branded (Non-GMO) ingredients - Sinetrol® Xpur and GreenSelect® Phytosome® - which have been developed and manufactured by European companies, what guarantees their high quality.

3. Thirdly, we believe that a good food supplement should contain only ingredients with pro-health effects. It should not contain additives and fillers, which may unnecessarily burden the body.

Slimvena™ contains only Sinetrol® Xpur and GreenSelect® Phytosome®. It does not contain any additives.

4. Fourth, and most importantly at the same time, we believe that a good, valuable dietary supplement should contain only ingredients with scientifically proven health promoting effects. It should therefore contain only these ingredients which have a beneficial effect on the human body (and as well are also generally safe to use) and this effect has been proven through clinical trials.

The ingredients that contains in Slimvena™ are exactly such ingredients. Clinical studies have proven that Sinetrol® Xpur and GreenSelect® Phytosome® to effectively support the process of weight loss and are generally safe to use.

We describe these clinical trials in the next section. So please, go to section:
