Thanks for posting your query.
The height of the man increases till the age of 21 years and cannot improve further.
According to human physiology, around the age of 21 years bones get closely joined together and they do not develop further,so the height of a male increases till 21 years of age, but we can’t absolutely say that height does not increase after this age. We can say that the development won’t be visible as it was earlier.
If you are 26 and you are not happy with your height, it does not necessarily mean that you should give up as there will still be a chance that your growth plates haven’t closed (only an x-ray can tell you this).
The essential amino acid
supplements like l- arginine
or l- ornithine
are not likely to increase the growth hormone
The best way then to improve your growth during this point is to increase the amount of growth hormone in your body by getting more sleep, and also by taking hot showers and exercising which also results in more growth hormone,doing yoga
Failing all this, if your height affects your confidence and lifestyle, then there surgical procedures available that can increase the length of your legs by breaking them and pulling them apart so that they heal between the gaps. This however is a very painful procedure that requires you to endure broken legs and bolts drilled into your bones for months or years.
The real best solution to the problem then, is simply to value the benefits of being slightly shorter and to come to terms with your natural height.
Be happy and enjoy your life.
