Chromium (Cr)
One of the 9 essential minerals
• 2500 years ago, Hypocrites, the “Father of Medicine”,
said to his students “Let thy food be thy medicine and
thy medicine be thy food”.
• In 1959, the mineral chromium was identified as an
active component in human nutrition. Our bodies
need Cr for normal growth and health, but it must be
obtained from our diet.
• Cr is part of the Glucose Tolerance Factor (with B3
and amino acids) necessary for the regulation of
blood sugar levels.
• Cr works with insulin for normal glucose metabolism
and conversion of amino acids into protein.
• Some causes of depletion:
Continued stress
Frequent sugar consumption
Strenuous physical exercise
• Deficiency is implicated in adult onset of
• Deficiency Symptoms:
Excessive or cold sweats
Dizziness or irritability after 6 hrs without food
Need for frequent meals
Cold hands
Need for excessive sleep or drowsiness during
the day
Excessive thirst
Other Uses and Effects
• Cr can be expected to lower blood sugar to some degree and insulin
levels may need to be adjusted to avoid episodes of hypoglycemia.
• Cr is important in the metabolism of fats and carbs
• Cr stimulates fatty acids and cholesterol synthesis and is an activator of
several enzymes.
• Cr also plays a role in the regulation of blood cholesterol levels. A study
showed modest reductions in plasma cholesterol and LDL cholesterol in
patients with high cholesterol as a result of treatment with Cr picolinate
for 6 weeks. (Humans, laying hens and pigs)
• Cr3 – Cr picolinate and vanadyl sulfate are two mineral compounds
being added to many nutritional supplements because they are
purported to have positive effects on energy and protein metabolism
and body composition.
• Cr is an essential trace element for humans, and the
recommended daily allowance (RDA) is between 50 –
200 micrograms/day.
• Dr. Richardson Anderson, a US Dept. of Agriculture
scientist who has spent most of is career studying Cr
points out that “since chromium is a nutrient and not
a therapeutic agent, it will only benefit those people
whose signs and symptoms are due to marginal or
overt chromium deficiency.
Where Do I Get it?
Cr 30 micrograms (as picolinate) can be found in:
 Liver
 Seafood (oysters, fish)
 Whole
wheat bread
 Mushrooms
 Asparagus
 Brewers yeast (trivalent
chromium active factor
 Egg yolk
 Molasses
 Beer
 Meats (beef, chicken,
calves liver)
 Green peppers
 Apples
 Bananas
 Spinach
 Butter
 Dairy products (cheese)
 Potatoes with skin
 Black pepper
 Thyme
Symptoms of toxicity:
Abdominal pain
Shock and coma
(these are normally due to exposure in industrial
