====== Introduction ====== ===== Prevalence in the 21st Century ===== ===== What is the market for these products? ===== ===== Are there risks associated with the products? ===== ===== Are they regulated? ===== ===== Additional Information ===== ====== Caffeine ====== Caffeine is viewed as the World’s most popular drug. ===== What is it? ===== ===== Mechanism ===== ===== Clinical Trail ===== ===== Legal Status ===== Caffeine is legal in every country in the world. There is recommended dosages to take to avoid various different health risks. Some of the major health concerns associated with caffeine include coronary heart disease, reproductive disorders and psychiatric disturbances.^[12] The intake of greater than 250mg of caffeine can acutely raise blood pressure, correlating with coronary heart disease. Caffeine has also been suggested to have harmful effects on unborn infants. Concerning psychiatric disturbances, the excessive consumption of caffeine has been proven to produce nervousness, restlessness, anxiety and insomnia. Anxiety neurosis is often misdiagnosed instead of Caffeinism.^[14] Many coffee drinkers appear to be addicted to the caffeine. Those who have been addicted and are trying to cut back can develop caffeine withdrawal syndrome which is recognized as an official diagnosis in ICD-10.^[17] ====== Ephedrine ====== ===== What is it? ===== ===== Mechanism ===== ===== Clinical Data ===== ===== Safety and Adverse Effects ===== ===== Legal Status ===== ====== Raspberry Ketone ====== ===== Introduction ===== ===== Mechanism ===== ==== Chemical Identity ==== ===== How to Manufacturer it ===== ===== Clinical Trials ===== ===== Legal Status ===== ====== Conclusion ====== When selecting and determining the efficacy of fat loss supplements it is important to examine the various ingredients listed on the label. The supplement industry is a for-profit business and oftentimes, there may be unsubstantiated and exaggerated claims of weight loss and it is therefore more crucial to look at relevant scientific studies to validate such statements. Furthermore, it is also imperative to critically analyze the studies that were performed and determine whether it the results can be applicable to human dosages. For example, studies done on raspberry ketones may show some promise in rodents, but has no evidence of efficacy in humans. Moreover, when converting rodent to human dosage, the required supplementation becomes astronomically high. Other critical variables regarding dietary supplements also include safety and toxicity. It is strongly advised for individuals looking at fat loss supplements to do their own extensive research on individual compounds and risks involved. ====== References ====== [1] Williamson, J.
