I will try to answer your questions as thoroughly as I can and will try to explain why a product is good or bad.
A good diet should include a lot of fruits and vegetables, as they are the best source of vitamins. They are also an excellent source of minerals, especially iron. Many people are afraid that taking supplements will lead to weight gain, so they buy the supplements that are advertised as "natural." Some of these supplements are actually high in fat, sugar and cholesterol, and contain dangerous drugs like diuretics. It is extremely important to look at the ingredients of each supplement to find out what you are buying. Some of these "natural" supplements contain more harmful drugs than they claim to, and many are actually no more natural than the commercial supplements they are intended to replace. Many people think that taking a supplement will help them lose weight and improve their health, but they are usually not taking the proper supplements, which will actually make you sick. These "healthy" supplements are actually quite dangerous. People who want to lose weight are often shocked to find out that they are actually taking medications to control their weight, and to help them to stop eating junk.
