Uric Acid Levels Low

Several issues are raised when levels of serum uric acid (a natural antioxidant) are low. It has previously been thought that lower uric acid levels were not associated with any problems but that may not be the case. Low uric acid levels may be associated with a molybdenum (Mo) deficiency, copper toxicity, and a worsening of multiple sclerosis.


Conditions that suggest Uric Acid Levels Low


Multiple Sclerosis / Risk

It has been proposed – and research is supporting the idea – that low uric acid levels are associated with increased frequency and longer bouts of multiple sclerosis. Uric acid works by inactivating peroxynitrite, a toxic compound that may cause damage to the central nervous system in MS patients. Researchers report that they found lower levels of uric acid in the blood of MS patients than of people without the disease. It appears that high serum uric acid levels protect against the development of MS. These results raise the possibility that the natural biologic product, uric acid, or a more soluble peroxynitrite scavenger that penetrates the blood brain-barrier more readily might have clinical utility in the treatment of MS.

Risk factors for Uric Acid Levels Low

Lab Values - Chemistries  

High uric acid level


Molybdenum Need

Xanthine oxidase, the enzyme that immediately produces uric acid, uses molybdenum as a cofactor. Molybdenum is known to raise uric acid levels, which is why people with gout (a condition of elevated high uric acid levels) are told to avoid molybdenum supplements.

Recommendations for Uric Acid Levels Low

Lab Tests/Rule-Outs  



Uric acid levels can be raised with supplemental molybdenum. While taking molybdenum orally may raise uric acid levels, IV administration may be required in some cases. Further evidence of an interaction comes from a study of men who consumed 10 to 15mg of molybdenum per day for prolonged periods who then developed high serum uric acid levels.

The cell-free fluid of the bloodstream. It appears in a test tube after the blood clots and is often used in expressions relating to the levels of certain compounds in the blood stream.


A chemical compound that slows or prevents oxygen from reacting with other compounds. Some antioxidants have been shown to have cancer-protecting potential because they neutralize free radicals. Examples include vitamins C and E, alpha lipoic acid, beta carotene, the minerals selenium, zinc, and germanium, superoxide dismutase (SOD), coenzyme Q10, catalase, and some amino acids, like cystiene. Other nutrient sources include grape seed extract, curcumin, gingko, green tea, olive leaf, policosanol and pycnogenol.


An essential trace element. It helps regulate iron stores in the body and is a key component of at least three enzymes: xanthine oxidase, aldehyde oxidase and sulfite oxidase. These enzymes are involved with carbohydrate metabolism, fat oxidation and urine metabolism. The average adult has about 9mg of molybdenum concentrated mostly in the liver, kidney, adrenal glands, bones and skin. Molybdenum deficiencies are associated with esophageal cancer, sexual impotency and tooth decay.


An essential mineral that is a component of several important enzymes in the body and is essential to good health. Copper is found in all body tissues. Copper deficiency leads to a variety of abnormalities, including anemia, skeletal defects, degeneration of the nervous system, reproductive failure, pronounced cardiovascular lesions, elevated blood cholesterol, impaired immunity and defects in the pigmentation and structure of hair. Copper is involved in iron incorporation into hemoglobin. It is also involved with vitamin C in the formation of collagen and the proper functioning in central nervous system. More than a dozen enzymes have been found to contain copper. The best studied are superoxide dismutase (SOD), cytochrome C oxidase, catalase, dopamine hydroxylase, uricase, tryptophan dioxygenase, lecithinase and other monoamine and diamine oxidases.

Multiple Sclerosis

Demyelinating disorder of the central nervous system, causing patches of sclerosis (plaques) in the brain and spinal cord, manifested by loss of normal neurological functions, e.g., muscle weakness, loss of vision, and mood alterations.

Nervous System

A system in the body that is comprised of the brain, spinal cord, nerves, ganglia and parts of the receptor organs that receive and interpret stimuli and transmit impulses to effector organs.


Specific protein catalysts produced by the cells that are crucial in chemical reactions and in building up or synthesizing most compounds in the body. Each enzyme performs a specific function without itself being consumed. For example, the digestive enzyme amylase acts on carbohydrates in foods to break them down.


A substance that acts with another substance to bring about certain effects, often a coenzyme.


A disease characterized by an increased blood uric acid level and sudden onset of episodes of acute arthritis.
