Are there any supplements that a boy of 17 can take to help him grow taller?

Ensuring that you're getting all the vitamins and minerals your body requires will help you grow to your full height. Take a supplement targeted at your age group with breakfast each morning, and try to incorporate certain foods into your diet. Get plenty of calcium (found in dairy products and green vegetables).

Calcium promotes bone growth, and can help prevent osteoporosis. Taking 500mg of niacin has shown to significantly increase growth hormone levels only when taken on an empty stomach 8. Get sufficient vitamin D (which can be obtained through eating fish, alfalfa, or mushrooms, or spending more time in the sun).

Vitamin D promotes bone and muscle growth in children9, and a deficiency has been shown to stunt growth and cause weight gain in teenage girls 10. If you don't like fish, consider a fish liver oil supplement. Take in lots of protein (from meat, eggs, tofu or legumes).

Proteins provide the essential building blocks your body needs in order to grow. At least one (preferably two) of your meals each day should include a protein. Up your zinc intake (oysters, chocolate, peanuts, eggs, peas, asparagus and supplements).

A zinc deficiency can cause stunted growth in children 11. The best way to make sure you meet your body's daily need is by taking a vitamin or supplement that includes zinc. Eat on a regular schedule.
