The ads for supplements to make you grow taller are so unbelievable that the people who wrote them must be laughing as they steal people's money for their totally worthless products. They tell you that if you take their pills, you can continue to grow until you are as tall as you like, at any age. If that were true, we would see people who are 15 feet tall and basketball would be an entirely different sport.

They want you to believe that when you eat their special blends that include kudzu vine or other rampant-growing plants, you will grow like the vines. Of course this is ridiculous. Kudzu vine grows rapidly because of its genetic structure called DNA, but you cannot absorb DNA from plants or animals that you eat; it is broken down in your stomach and intestines into amino acids, the building blocks of protein.

Or they tell you that their product will stimulate your growth hormones, but even if that were true, once you have gone through puberty, no amount of growth hormone will lengthen your bones.

Bones do not grow throughout their length. They grow from growth centers, called the epiphysis, near their ends. When a person reaches puberty, growth centers close one after the other until all the growth centers are closed forever and a person's bones can never grow again. After that, a person can grow wider, but not taller.

The tragedy is that people will shell out their hard earned money to someone who is making fun of them. The promoters offer a money-back guarantee, but they know you will probably be too embarrassed to ask for your money back, and many people report that their money is never returned when they request it from these scams.
