The hormonal (endocrine) system affects almost all important life processes: metabolism, reproduction, adaptation to the environment, immunity, maintaining a healthy weight, and much more. Any hormonal disruption immediately affects the general health condition of a person.
In turn, the work of many organs also affects the hormonal balance. The most important are the thyroid gland, hypothalamic-pituitary system, adrenal glands, and thymus.
Cedar nut oil has a beneficial effect on all organs and systems associated with maintaining hormonal balance, therefore it is effective in the prevention of endocrine diseases.
Let's take a look at what substances in cedar nut oil are necessary to maintain the health of the most important organs of the endocrine system.
This organ produces thyroid hormones that are necessary to maintain normal metabolism. Thyroid hormones are also needed for a healthy mental and physical development, that’s why thyroid is especially important for children and adolescents.
Trace element that supports the normal functioning of the thyroid gland is iodine that is found in large quantities in cedar nut oil. Other nutrients in the oil are also important for the thyroid gland:
— Vitamin A affects thyroid metabolism 
— Selenium: Low plasma levels of this mineral are associated with an increased risk of autoimmune thyroid disease. 
The thymus is the organ where the synthesis of T-cells occurs. These cells play a critical role in immunity. The thymus is especially important at a young age (up to 30 years), and then gradually gives up its functions to other glands. Cedar nut oil is a completely natural dietary supplement that can be taken from a very young age. It contains the following substances necessary for thymus health:
— Antioxidant Vitamins - A, C and E
— Zinc - a deficiency of this mineral leads to serious malfunctions of the thymus and entails problems with the immune system. 
Hypothalamus and pituitary gland
The hypothalamic-pituitary system produces releasing hormones, oxytocin, and vasopressin. Each of these hormones has its own functions, a deviation in their synthesis can lead to cognitive and cardiovascular disorders, psychological problems, and various diseases of the reproductive system, up to impotence in men.
For the work of the hypothalamus and pituitary gland, iron, polyunsaturated fatty acids, zinc, selenium, and magnesium, contained in cedar nut oil, are important. In particular, studies have shown that polyunsaturated fatty acids can significantly reduce the negative effects associated with multifactorial disorders on the hypothalamic-pituitary axis 
The adrenal glands are involved in the regulation of metabolism and in the process of adaptation to adverse conditions, reactions to stressful conditions. The adrenal glands produce hormones such as adrenaline, norepinephrine, and corticosteroids.
Cedar nut oil contains vitamin B6 and zinc. A deficiency of these nutrients leads to disruption of the adrenal glands.   Cedar nut oil is also a source of pantothenic acid that stimulates the production of corticosteroids.
Thus, due to the content of a large amount of a complex of nutrients, cedar nut oil has a complex effect on the organs associated with the endocrine system and helps to maintain hormonal balance.
