Articles (Health, Fitness & Supplement Product Based)

I'm launching a website shortly and need some immediate content. Specifically, content about ingredients used in supplement and health products. As to what their purpose is, how they are formed, basic information and effects on the human body; in particular the physiological effects/ adaptations either before or after exercise. It will require some food science knowledge; possibly in the form of explaining (briefly) how the ingredient is extracted/ manufactured if its synthetic and to note if there are any dangerous levels of over consumption in the human diet. These ingredients can be found on all products and a majority of them are used in more than one product. Typically the products in question are categorized into protein, weight gainers, creatine, pre workout, recovery and so on... and can be found on most retailer websites. I am more than happy to provide a URL to websites which I believe have a large product database which will provide the ingredient names. I will not just require sport supplement ingredients, but that of ones used in health supplements. Such health products are found in shops like Holland and Barrett, Boots etc etc... I need the articles to be 'short and sweet' as you well know, an article which is far too lengthy will not attract repeat traffic nor be beneficial to conversion rates. Therefore the style needs to be attractive, broken down for information to be extracted easily by the user and typically be 500 words (approx). Images (if possible) will also be required.
