Pregnenolone side effects and Pregnenolone benefits
Pregnenolone is a natural hormone that cannot be patented. Back in the 1940's, when researchers started experimenting with the use of pregnenolone, they realized that it could be helpful for people under stress and it could increase energy in those who were fatigued. However, about the same time, cortisol, another closely related hormone, was discovered. Cortisol stole the limelight. When cortisol was given to individuals with rheumatoid arthritis, there were outstanding short-term improvements. Photographs of these remarkable recoveries were circulated and the medical community was impressed. Scientists basically put pregnenolone aside to focus on cortisol. The structure of cortisol was altered to make similar molecules such as dexamethasone and prednisone, much more powerful steroids. Dexamethasone and other similar corticosteroids could be patented, and thus a pharmaceutical company could make a lot of money by owning patents.

Benefits of pregnenolone
Some people find pregnenolone improves energy levels, vision, memory, clarity of
thinking, wellbeing, and often sexual
enjoyment. Some women report lessening of hot flashes or premenstrual symptoms.
Studies in rodents show pregnenolone to be one of the most effective and powerful memory
boosters. Pregnenolone may increase levels of acetylcholine in the hippocampus and other
memory regions in the brain. However, pregnenolone is not risk-free.

Side effects of
high dose pregnenolone tablets or capsules
Overstimulation and insomnia. Insomnia can lead to fatigue and
exhaustion. Some people feel sleepy after they take a pregnenolone supplement.
Irritability, anger or anxiety
Acne
Headaches
Possible scalp hair loss if used daily for prolonged periods
Irregularities of heart rhythm, palpitations on high doses
Unknown effects on the thyroid gland or other organs
Pregnenolone danger
We're still in the early stages of learning about pregnenolone and its full
effects on the human body.
It is best to proceed with caution until more information is available. This means using
the lowest effective dose and seeking supervision by a knowledgeable health care provider.
There are some medical or psychiatric conditions where pregnenolone can be used
temporarily and then stopped. With this conservative approach, it is unlikely that any
problems would arise. Our major uncertainty at this time involves the long-term use of
pregnenolone as hormone replacement therapy, especially if high doses are used.
Pregnenolone can also cause heart palpitations in high doses.
With time, as more and more people use this hormone, we'll have a
fuller understanding of its benefits and side effects. Those who have already found pregnenolone to be helpful in terms of mood elevation, stress reduction, arthritis help,
visual and auditory enhancement, and so forth, but are concerned about unknown long-term
effects, may feel more comfortable using pregnenolone only as needed and frequently taking
time off from it. Taking these "hormone holidays" will mitigate any potential
unknown risks.
Daily use of pregnenolone over prolonged
periods should be no more than 1 to 3 mg unless you are closely followed by a health care
practitioner familiar with the clinical uses of this hormone. Current dosage available
over the counter, such as 25, 50, or 100 mg are TOO high. If you purchase a 10 mg pill or
capsule, take a portion of it if you plan to take it on a regular basis.
How is Pregnenolone made?
There is a type of plant called a wild yam that is grown in certain parts of the
southern U.S. and in Mexico. This wild yam contains a compound called diosgenin that is
the precursor to steroid hormones. In a laboratory, diosgenin is converted into
pregnenolone. Further laboratory processing can convert pregnenolone into DHEA. The human
body does not have the ability (the required enzymes) to convert diosgenin (a six ring
structure) into pregnenolone (a four ring structure). Therefore, if you swallow pills that
are extracts of wild yams (diosgenin), you will not get pregnenolone or DHEA. The
conversion of diosgenin to pregnenolone has to be done in a laboratory. If you want
pregnenolone or DHEA, the bottles you buy must say that they contain actual pregnenolone
or DHEA, not extracts of wild yams or diosgenin.
What form of pregnenolone is best?
Oral
pregnenolone pills work well. Sublingual or micronized are also good options.
Can I take pregnenolone if I'm already on DHEA, estrogens, or
other hormones?
Since both DHEA and pregnenolone have some similar effects (however, they have
differences, too), you should lower your dose of
DHEA when you go on pregnenolone. The
lowering of the dose should by the same amount as the pregnenolone dose. Before you add
pregnenolone, though, make sure you try it separately to see what kind of effects it has
on you, Once you know how you react to
DHEA and pregnenolone separately, you can then
combine them. The amount of conversion of pregnenolone to estrogens is not fully
known. Progesterone
has some overlapping effects to DHEA and pregnenolone. The role of pregnenolone
hormone supplement use for
menopause is a possibility that has not been studied adequately.
Pregnenolone
blood level - normal range of pregnenolone
What would be considered a normal and/or
optimal pregnenolone level for a 43-year-old female? From what I have read, this
hormone naturally declines with age. Can you please provide normal levels and
corresponding age ranges for pregnenolone. Is there any research available
pertaining to the causes of pregnenolone depletion? Finally, if one is taking
pregnenolone in order to raise a low level of this hormone, do you have any
information on how long and how much should be administered?
Different labs seem to have different normal ranges for
pregnenolone. One lab has the range listed between 0.1 and 3 ng/ml. We found
another lab that has the range for pregnenolone as 0.1 to 25 ng/ml. Another lab
listed normal pregnenolone range to be 20 to 150 ng/ml. Most list a normal range
of pregnenolone as 10 to 230 ng/ml.
We have not seen any specific research on pregnenolone depletion.
Pregnenolone is made in the adrenal glands and it is likely that factors that
influence the adrenal glands as a whole influence not only pregnenolone but the
other hormones made by the gland. Pregnenolone use as a supplement, the dosage
required, and the length of time used is made on a case by case basis. The only
general statement that can be made is to using this hormone in the least dosages
possible and for the least period of time necessary. At this time, we are not
convinced that pregnenolone dosage, in terms of supplementation, can be
accurately determined by blood tests. If you provided ten doctors with a
pregnenolone level of a patient and asked to recommend a starting pregnenolone
supplement dosage, you may get ten different dosage recommendations.
There could also be variations in pregnenolone levels on different
days, so a one time level does not necessarily mean that the pregnenolone serum
level is that level all the time. Please keep us updated on your experiences
with pregnenolone, and you may ask your doctors to read the pregnenolone page
regarding the cautions.

Q. Pregnenolone : Well I am a 34 years of age, male and in good health. I have
noticed that even on 2.5 mg of pregnenolone I get enhancement in vision, sounds
and also an over all absorption in my surroundings but I also get mild anxiety
which I don't know how to counter. I can't focus on or sense memory improvement
because of the interference from anxiety. Hope i can find a way around this
anxiety...lets see.
Q. I came across some information on
pregnenolone while doing research on the internet. I have been seeing a
nutritional consultant for about the past six months, and after a saliva
analysis to test my hormones after I had a miscarriage in July '06, he
determined that I was in need of lowering my cortisol levels and slightly
boosting my progesterone (nothing major) to help rebalance my hormones. He put
me on 100mg of pregnenolone that I take as a single dose in the morning. After
reading pregnenolone side effects on a website, I started to get nervous since
we have been trying to conceive again for the past six months with no luck. I am
26 years old, and my husband and I have one healthy 18-month old, so getting
pregnant has never been an issue for us in the past. I have been seen by two
different OBGYNs to assess whether or not there is anything anatomically wrong
with me, which both doctors have determined that there isin't by doing
ultrasounds and bloodwork. My husband has also been tested and his analysis came
back fine as well. Do you think that the pregnenolone could be the cause of us
not being able to conceive again, and if so, what measures I should take to wean
myself off of it?
A. It is impossible for us to know in your particular case whether
pregnenolone is the cause of not being able to conceive and we are not in a
position to offer individual advice. We would suggest your nutritional
consultant read the cautions on pregnenolone high dosage use.
Q. I am confused by some advice that I
read on a website. In regards to DHEA and
pregnenolone, Dr. Ray Sahelian states
"I do not feel comfortable with the high dosages of DHEA and pregnenolone sold
over the counter. I think a maximum of 5 mg is acceptable". However, in an
interview he gave to Life Enhancement, he is quite optimistic about the safety
and benefits of both DHEA and Pregnenolone in higher doses and even speak of a
patient that he put on 20mg of pregnenolone and 10mg of DHEA, with positive
results. Did he change his opinion about the safety of DHEA and pregnenolone?
A. Yes, after further experience, Dr. Ray Sahelian has realized
that DHEA and pregnenolone hormones are much more potent than he first
understood them to be, and hence he has revised his dosages lower.
Q. I, perhaps, too late have read your
warning about pregnenolone side effects. I was put on pregnenolone at 20mg four
years ago by a doctor who was trying to lower the level of hydrocortisone dosage
I was placed on for chronic fatigue syndrome. I was unable to lower the
hydrocortisone dosage -- and also found it difficult to stop the pregnenolone.
Last spring I tried to lower the pregnenolone and immediately got mouth sores.
Went back on it, and they went away. In December tried to lower the
hydrocortisone and a range of symptoms suddenly appeared. It now appears that I
may have systemic lupus erythematosus. I fear that the impact of the
pregnenolone on my immune system may have lead to this current awful place. My
neurologist wants me to lower the pregnenolone as he thinks it may be implicated
in my lupus -like symptoms, which include peripheral neuropathy, but he knows
nothing about it. I don't know if you have any thoughts on this matter. At any
rate, please feel free to use this as a cautionary tale in relation to
pregnenolone side effects and usage.
A. We have not heard of lupus like reactions to pregnenolone usage,
perhaps the hydrocortisone dosage may have had an influence or it could have
been a coincidence. Nevertheless, perhaps the pregnenolone dosage can be reduced
by 1 mg a week.
Q. I recently came across Dr. Ray Sahelian
web site while researching pregnenolone, after being prescribed it by my doctor.
I did extensive research, as well as talking with my doctor, and after reading
dozens of websites or excerpts from books about how safe it was, and having
virtually no known toxicity or side effects, I found his. So, I understand that
there's always two sides to a story (I'm used to that being in the alternative
health field), but I simply don't understand how there can be so many books,
studies, websites, etc out there that say flatly that pregnenolone, except in
extremely high doses (if that) will have NO side effects whatsoever, but Dr.
Sahelian is adamant that even LOW doses do. I'm confused as to how these other
researchers, many doctors themselves, have missed the obvious side effects? I'm
not meaning to sound negative, but it's frustrating trying to figure out who is
"right" and who isn't.
A. What sets Dr. Ray Sahelian apart from most doctors is that he
takes the supplements he writes about, including pregnenolone, in varying
dosages and has first hand experience. Plus, he has feedback from patients and
thousands of people who write to him regarding their experiences. Furthermore,
Dr. Ray Sahelian has integrity and will mention side effects of supplements and
not try to hide them. It is ultimately up to each individual to obtain
information from various sources and determine which is the most reliable and
believable.
Q. Do dhea & pregnenolene help in treating
high cholesterol? I have been taking them for about 6 weeks. But I have read
your web page and am concerned.
A. DHEA and pregnenolone are too dangerous to make them first line
therapy for cholesterol elevation. There are many other safer options to first
try.
Q. I am 46 yr old female, Asian, muscular
and lean 120 pounds, very athletic, and in optimal health. 2003 found Uterine
Fibroids and that was removed. Using Progesterone cream after the surgery kept
the returning fibroid to grow slowly. Started having irregular periods in 2005
so I have been on DHEA 25 mg a day since (9 months) and have been getting
regular periods within 2 months..... fuller breasts and nothing else changed.
Serum test in Feb 07 showed low Progesterone and Pregnenolone levels so I
started taking Pregnenolone 50 mg a day for the last 6 weeks. Within 3 weeks
started having VERY full, sore, aching breasts nipples and hormonal PMS lower
back and upper thigh aches. Did seem to kick in libido., in a negative way.
Became worse as the weeks went on. I stopped completely both DHEA and
Pregnenolone and the tenderness is going away daily. I was advised to stop DHEA
and stay with Pregnenolone because Pregnenolone is a slower converting hormone
by the foundation I was purchasing it from....doctor on staff. Is that true?
Which do you advise me to experiment with? I will stop for awhile.
1. DHEA alone
2. Pregnenolone alone
3. or combination but in what doses?
I will continue on Progesterone cream however since that helps
balance out my estrogen levels. The blood test show my estrogen was a bit high,
testasterone (and free T) normal and the rest were normal with excellent lipid
profile.
A. We can't give individual advice. Hormones, even over the
counter, are extremely potent. We suggest you read all the cautions on this
website regarding the potential side effects of DHEA and pregnenolone. These
hormones should not be used casually. They are meant to be used for those who
have a serious deficiency in the production of these hormones. Other natural
options such as diet, exercise, relaxation, yoga, and natural non-hormone
supplements should be tried before resorting to the use of hormones. And if they
are used, they should only be taken in the lowest effective dose for the
shortest period of time required for symptom relief.
Q. I was wondering if you could comment on
whether the blood test for pregnenolone is useful for determining a deficiency?
My doctor ordered the blood test and I was below the detectable level
(<10ng/Dl), the range given as "normal" was 10-200 ng/Dl. She has recommended
taking 10mg/day for awhile to bring the level back up.
A. There is no agreement in the medical community as to the
appropriate dosage of pregnenolone to be used as a supplement in those who are
deficient. As to hormone replacement, the whole clinical picture has to be taken
into account as opposed to just one value of a hormone tested in one particular
day.
Q. I bought some pregnenalone but am not
sure about how to take it. I read on one website that one should do 'vacations'
and not take it every day. Is that 3 days on and 4 days off? I have been taking
the recommended 'bite' on mondays, tuesday, wednesdays. Is this the kind of
rhythm?
A. There are no strict guidelines on how to take pregenolone since
each person has a different need or response. As a general rule, there should be
a good reason for taking this hormone, and the least amount and frequency should
be used.
Q. My doctor prescribed a 100 mg/cc
pregnenolone trans-dermal cream to be applied 1/2 cc two times a day. She wants
me to do this treatment for 4 weeks and then re-take labs. Does a 50 mg
pregnenolone oral dosage twice daily equate to a 100mg daily dosage
transdermally or is only a certain percentage of pregnenolone absorbed through
the skin.
A. We have not seen any studies comparing the absorption of
pregnenolone taken as a pill versus a pregnenolone cream. There are a number of
variables. Oral pregnenolone is absorbed from the intestinal tract and goes
through the liver first and somewhat modified. transdermal pregnenolone will not
have this first pass effect through the liver. The amount of pregnenolone
absorbed through the skin depends how the cream product is formulated, in other
words what kind of agents are used in the cream besides pregnenolone, the part
of the body where you apply it, and your particular dermal absorption may be
different that another person's absorption through skin. But, most importantly,
it is important to read the cautions on pregnenolone use since this is not a
hormone to play with carelessly.
Q. I am reading Dr. Sahelian's book,
Pregnenolone. I have not taken the hormone yet, but I notice that Young Living
Essential Oils sells a product called PD 80/20. The amount of pregnenolone is
640 mg and DHEA 160 mg. That is so very excessive that it seems dangerous. Here
are the stats:
PD 80/20 is a dietary supplement formulated to help maximize internal health and
support the endocrine system.* It contains pregnenolone and DHEA, two substances
produced naturally by the body that decline with age. Pregnenolone is the key
precursor for the body's production of estrogen, DHEA, and progesterone, and it
also has an impact on mental acuity and memory.* DHEA is involved in maintaining
the health of the cardiovascular and immune systems.*
Pregnenolone: 640 mg per serving, DHEA: 160 mg per serving
How to use: Start with 1 capsule per day, then increase to 2 capsules per day as
needed.
A. The dosages of pregenenolone and DHEA appear to be quite
excessive and potentially dangerous if it truly contains 640 mg and 160 mg.
Q. I was just wondering how much
Pregnenolone is safe to take? I'm a 48 yrs old, male, and I've had my blood
tested by "LabCorp". The test indicated that I could safely take 50 mg per day.
Does that sound about right if the test indicated that I was deficient by 50 mg
of pregnenolone hormone per day?
A. Lab tests for pregnenolone are not a reliable way to determine
the required or beneficial dosages to supplement with. Pregnenolone is potent
and potentially dangerous hormone if misused.

Q. About three weeks ago, I had my
progesterone and DHEA tested. Both were low. We did not test my pregnenolone or
testosterone. I am currently taking progesterone and 7-Keto DHEA, but I just
read that 7-Keto dhea does not raise your DHEA level. If progesterone and DHEA
levels are both low, could this possibly mean that pregnenolone may be low also
since it converts to progesterone and DHEA? Could simply supplementing with
pregnenolone balance levels of both progesterone and DHEA?
A. The whole issue of hormone supplementation is very complicated
and there are no simple answers. It is possible that taking pregnenolone could
elevate levels of progesterone and DHEA. However one must focus on treating the
whole body rather than treating hormone levels. If a person feels well and has
no major symptoms, there is no point in taking hormones even if certain hormone
levels happen to be slightly low. There is a danger supplementing with hormones
and it could turn out to be counterproductive.
Q. I have come across your website
while searching for info on pregnenolone. I am a long distance runner from South
Africa and want to know if it is illegal for athletes to use pregnenolone? I am
45 years old and found that my energy levels are increased markedly by the use
of this steroid.
A. We are not sure whether athletic organizations test for
pregnenolone, some may, others may not. Pregnenolone does increase energy levels
but it could also cause heart rhythm problems.

Q. I was given 100 mgs of pregnenolone
supplement by a chronic fatigue specialist. I had a heart attack and 3 stents. I
am confirming what you say concerning dangers of pregnenolone high doses.
PLEASE, PLEASE get the word out.
A. Can you give us more details?
Q. My case is complicated, but I think will
eventually support what Dr. Sahelian suggests. Within a few days of being put on
100 mgs of pregnenolone hormone, I had a heart attack and 3 stents. But let me
digress. I have had chronic fatigue syndrome since 2004. I was first diagnosed
in August of 2006. I followed Jacob Teitelbaum's protocol through my brother who
is a family physician. Finally, in November of 2007, I went to a chronic fatigue
syndrome CFS specialist because I needed more specialized care. Prior to that,
my brother had done many tests......... blood, heart etc etc. In September of
2007 I had a stress test done. I passed that test with flying colors ( however I
understand it is not fully accurate.) The other 2 tests results never made it
back to him until just before the heart attack ( 1/30/08) They revealed that I
had a severely hypokinetic left ventricle septum and an ejection fraction of
49%. The chronic fatigue syndrome CFS specialist did not request those test
results and proceeded to give me 100 mcgs of pure T3 hormone and 10 mgs of
hydrocortisone on December 24th. I could not take the hydrocortisone and got
extremely ill. I quit it in early January. By the time of my next appointment on
January 22, 2008, I complained that the T3 was making me extremely
hyperirritable. He reduced it to 87.5 mcgs. At that time I was given 100 mgs of
pregnenolone to add to my protocol. I started it on January 23rd. On Sunday
January 27th I started with symptoms of chest pain. They went away and came back
3 times that evening. ( I thought they were indigestion problems because they
started with dinner). They did not return until January 29th. in the evening. At
1:30 AM ( 1/30) I again woke with pains that resulted in crushing chest pain and
other symptoms. As I said, this is a complicated case, but may reflect what Dr.
Sahelian is suggesting. High doses of pregnenolone can result in atrial
fibrillation. This is what the ER doctor diagnosed me with before sending me on
for a heart catherization. Prior to this I never had a single heart problem. No
blood pressure problems, cholesterol issues, weight issues etc etc. In fact, I
looked like the picture of health other than my chronic fatigue syndrome CFS. As
I was researching, I came across Dr. Sahelian's website and thoughts. I do not
think it an accident that this happened within a few days of the high
pregnenolone dose.
Q. I took Pregnenolone for several
years ... one 50 mg capsule each day. For the last couple of years, I have
noticed that my hair is much thinner than it used to be and I was puzzled until
I read in Mind Boosting Secrets that Pregnenolone could have that effect on
hair. Immediately I discontinued taking Pregnenolone. That was about six months
ago but I have not seen any difference in my hair. My question is: if this
hormone is responsible for my hair thinning, can its effect be reversed by
discontinuing the use of this hormone? While, I am female, have always had thick
hair, and am now 70 years old ... my family history shows no sign of hair
thinning or balding in either sex ... quite the reverse ... a good head of hair
into old age.
