Foods That Increase Somatotropin

Updated July 20, 2017

Also known as the Human Growth Hormone (HGH), somatotrophin is a hormone produced by the pituitary gland. According to, it contains 191 amino acids and stimulates the liver to release another hormone called somatomedin, thus initiating growth. Somatotrophin is also thought to have anti-ageing effects on the body. Certain foods can cause an increase in somatotrophin levels. To boost your body's somatotrophin production, eat several small meals throughout the day and focus on foods that are low on the glycemic index.

Vitamins and Minerals

Vitamin E will help increase somatotrophin levels and improve your cell wall permeability. Foods rich in vitamin E include avocados, pumpkins and apricots. Copper not only aids in the creation of red blood cells, it encourages the production somatotrophin as well. Nuts, seeds, chickpeas, liver and oysters contain high amounts of copper. The zinc found in poultry, dairy and whole grains will also improve somatotrophin output.


Iodine and the l-tyrosine amino acid combine to synthesise thyroid hormones, which are essential for growth. According to the Linus Pauling Institute, processed foods often contain higher levels of iodine because of salt and iodate additives. Eggs, fish and potatoes contain solid amounts of iodine but seaweed is by far the most iodine-rich food.

Glycemic Index

To increase somatotrophin, keep insulin levels down by choosing foods that are low in sugar and rich in complex carbohydrates. The Healthier Life website states that when there is an excess of insulin in the blood, the body reacts by producing a chemical called somatostatin which suppresses the release of somatotrophin. Foods such as nuts, seeds, beans, fruits and vegetables are all low on the glycemic index and will keep blood sugar levels constant. Avoid pasta, refined sweets, corn syrup, honey and maple syrup.


Fasting has also been recommended for improving somatotrophin and promoting longevity. Consult a medical professional before attempting to fast or switching to a very low calorie diet.
