Vitamin
H
Common
Name: Vitamin H
Synonym: Biotin
CAS No.: 58-85-5
Biotin, as referred
to as Vitamin H is part of the Vitamin B complex group and might be
interesting to some people since one of the most visible symptoms
of shortage of this vitamin is thinning of hair which can lead to
total hair loss.
This does not
mean that baldness is a sign of Vitamin H in short supply - severe
hair loss might just be indicative of biotin being deficient.
Vitamin H - biotin
- is required for:
Vitamin H is used in cell growth, the production of fatty acids, metabolism
of fats, and proteins. It plays a role in the Kreb cycle, which is
the process in which energy is released from food.
Biotin is also
indicated for healthy hair and skin, healthy sweat glands, nerve tissue,
and bone marrow, and assisting with muscle pain.
Vitamin H not
only assists in various metabolic chemical conversions, but also helps
with the transfer of carbon dioxide. Biotin is also helpful in maintaining
a steady blood sugar level.
Deficiency of
biotin - vitamin H:
Although a shortage of Biotin is very rare, it can happen and may
result in dry scaly skin, fatigue, loss of appetite, nausea and vomiting,
mental depression as well as tongue inflammation and high cholesterol.
Dosage:
Adults 300 microgram (0.3 mg) per day and pregnant and lactating women
300 microgram (0.3 mg) per day.
Toxicity and symptoms
of high intake:
No known toxic levels are known, as excesses are easily lost in the
urine and feces. No known side effects are known.
Best used with:
Biotin should be taken with the B-group vitamins, but Vitamin C, Vitamin
B 5 (pantothenic acid), Vitamin B12 and sulfur are good companions
to it. A tricologist will sometimes add biotin to the diet of a patient
suffering from alopecia, to help with severe hair loss, but it must
be in the right quantities to satisfy the inter-dependence of other
nutrients - such as found in our Hair, Skin and Nail supplement
When more biotin
may be required:
Bodybuilders and athletes consuming raw eggs should be careful of
not running into a biotin shortage, since raw eggs contain avidin,
which binds with the biotin, making it impossible to be absorbed by
the body.
Long term users
of antibiotics may also have to look at their biotin levels.
Enemy of element:
Biotin is not easily destroyed
Other interesting
points:
It seems that biotin may affect hair color, together with PABA, folic
acid and pantothenic acid. Some research had varying results with
biotin supplements in returning hair to it original color.
This has proved
only successful to a limited degree and only when natural vitamins
were used, as the synthetic vitamins did not influence the results
very much.
Food sources:
Biotin is present in cheese, beef liver, cauliflower, eggs, mushrooms,
chicken breasts, salmon, spinach, brewer's yeast, nuts and can be
manufactured in the body should a small shortfall occur.
