Scientific research has shown that the adaptogenic Eurasian herb rhodiola significantly
increases tolerance to various stressors (e.g. mental, physical, environmental). Rhodiola
acts predominantly on the hypothalamus (the hormonal initiator of the stress response)
in a way that regulates the manner in which the body responds to stress triggers.
Evidence also suggests that this herb has a potent enhancing effect on brain serotonin
activity, an attribute that may be of great value in reducing the anxiety-related
symptoms associated with chronic stress.

Siberian Ginseng
Although Siberian ginseng is not a true ginseng species, like ginseng it increases
tolerance to various stressors (e.g. mental, physical, environmental). This herb helps
normalise the way in which the body responds to stress triggers and acts to regulate the
manufacture and secretion of adrenal hormones. It also strengthens the adrenal glands
themselves, which is especially important to those suffering from chronic stress.

Magnesium and Calcium

Primarily due to their requirement for proper function of the nerves and muscles,
deficiencies in the minerals magnesium and calcium may lead to irritability, tension and
insomnia. Levels of these nutrients, especially magnesium, are likely to be depleted
during stress. Magnesium is required as a co-factor for the production of energy,
including adrenal energy, and the production of adrenal hormones and also helps to
combat some of the negative effects of stress such as hypertension, platelet aggregation
(blood clotting), and vasoconstriction.

B-Complex vitamins

B vitamins are vital to stress tolerance; as well as being essential to proper nervous
system function, certain ones are also needed for adrenal gland function and adrenal
hormone manufacture. B vitamin deficiencies are often associated with anxiety and
nervous disorders.
