Clinicians Family C powder provides three forms of vitamin C in a complex with bioflavonoids to support a health immune system and circulation. Vitamin C helps the body promote a vigorous immune response to infection. Vitamin C is essential for the production of adrenalin. Poor adrenal function can initiate anxiety, fatigue, energy loss and sleep difficulties. Vitamin C is vital for: first line defence against 'oxidation' and 'free radical' damage, both of which are known to initiate many of the most common diseases, maintenance of health connective tissue and bones, normal metabolism of cholesterol and the production of cortisol by the adrenal gland, the production of collagen and the metabolism of various brain chemicals and for the synthesis of the hormone noradrenalin, which has powerful effects upon pulse rate and blood pressure.
