Are you struggling with hair loss? In this video
i'm going to explain if biotin can help your hair
grow faster! NEXT!
A variety of vitamins play a role in hair growth
including vitamin a B12, C D, E and biotin. These vitamins
in combination play a role in the growth of
thicker healthier hair but, we're here to talk about biotin!
So what is biotin? It's also known as vitamin H
the H is derived from the german words Haar und Haut meaning hair and skin.
It is also known as vitamin B7. Vitamin B7 is a water soluble vitamin,
that means it's not stored in your body for long.
Where is biotin found? It is found in a variety of foods
and the list is so long, however, i'll mention just a couple so
that you have an idea of food sources: egg yolk
oak flakes, nuts, soy beans, spinach, milk and milk products, pork
beef, carrots, tomatoes and apples. The fruits I mentioned before are not
hard to find so biotin deficiency is
rare. Moreover biotin is also produced by your gut bacteria, but what we don't
know yet because of the lack of quality studies
is how much biotin is produced. The other thing to know is that
different types of food contain various amounts of biotin
for example egg yolk and milk contain higher amounts of biotin than
certain vegetables, however, this alone is not the
decisive factor, but how much food gets into your body
we refer to this as bioavailability. Bioavailability also depends
on the extent to which biotin is protein-bound.Meat contains
protein-bound biotin whereas plant biotin is available in free form.
Can we measure biotin plasma levels? Yes, we can measure B7 levels and the normal
biotin plasma concentration ranges from 400 to 1200 nanograms per liter,
but these levels can fluctuate therefore to get a really
accurate level you will need to do this
test over a two to three day period, therefore, the test is not seen as a
sensitive marker; more importantly this is not practical
Who wants to get a test done that often! Moreover,
these tests are not common and they're pretty expensive.
A more accurate test would be to measure a metabolite
called - hydroxy isovaleric acid in the urine seen in biotin deficiency.
The normal biotin blood plasma level in healthy individuals
range from around 200 to 1200 nanograms per liter
with an optimum level of 400 to 500 nanograms per liter
in young adults and in children. In older adults
the value is around 300 nanograms per liter.
Independent from the cause a biotin deficiency
always exists when the plasma biotin level
is below 100 nanograms per liter. If you're finding value in this video

How much biotin do we need in our diet? Recommended levels of adequate intake
by the food and nutrition board of the institute of medicine
of biotin is between 35 and 70 micrograms per day if taken as a
supplement the recommended dose is 30 mcgs per day
and if you're pregnant it is 35 mcgs per day;
and, a note of caution if you're taking biotin it can interfere
with a number of lab tests such as thyroid function tests other
tests which can be affected are digoxin,
ferritin, testosterone, BNP, and progesterone as well.
Your doctor will also advise that biotin can interact with antibiotics
such as azithromycin and ciprofloxacin. So, who has lower levels of biotin?
Alcoholics, smokers, patients on tube feedings,
patients on isotentinoin for acne treatments,
patients on anti-epileptics such as vaporic acid,
patients who've had a partial stomach removal
with lower or no levels of stomach acid production, prolonged use of
antibiotics interrupting normal gut flora,
impaired intestinal absorption like inflammatory bowel disease,
in elderly patients, patients who are pregnant and lactating,
an acquired deficiency is seen with increased raw
egg consumption. Raw egg whites contain a protein
Avidin that blocks the absorption of biotin,
so, people who regularly consume a large number of raw eggs for several months
may become biotin deficient. So, how do symptoms of
biotin deficiency look like? So you can see
changes to the skin like red rashes especially around the face, a dry and
scary skin, brittle hair, hair loss, fatigue,
insomnia or difficulty sleeping, loss of appetite, nausea, depression
hallucinations, burning or prickling sensation in the hands
and feet. Question of the day? Are you suffering from hair loss
and has any supplement helped you? So when can
biotin be given for hair los? So, if the hair loss
is associated with a nutritional deficiency
supplementation with biotin can be given. As already mentioned biotin deficiency
is rare especially if your diet is well balanced.
Biotin has been shown to help with splitting
brittle nails. Study data also shows that people can
safely consume biotin at much higher levels than the adequate
intake I mentioned earlier in this video
without any health problems because of favorable
side effects and toxicity profiles. So what are the steps
if biotin deficiency is suspected especially with values below 100
nanograms per liter this can be treated with supplementation
as well as nutritional supplementation; at the same time other causes of
deficiency such as thyroid disorder have to be
excluded. For example in a study looking at biotin
deficiency 38% reported levels lower than 100
nanograms per liter and 49% reported levels
lower than 400 nanograms per liter, however, 11 percent
were found to have other reasons explaining lower biotin levels
such as being on antibiotics or isotrentinoin.
So when is this doctor going to talk about how fast
biotin might work! Well right now! Now, I have to mention a double blind study
showing that biotin helped with thinning hair
and helped speed up the rate of hair growth.
In this study a marine protein supplement containing biotin versus
placebo was given to test subjects over a 90
day period. Images of the scalp were taken of the affected areas
Researchers could then demonstrate that women who took the supplement hair
growth was promoted in the areas affected;
also there was decreased hair loss in women with thinning of hair. Of note
this particular study I have to say was sponsored by
grant from Lifetogood Inc. So there you have it
