Gelatin and safety
• In 1993, the FDA reiterated the “GRAS” (Generally
Reconsidered As Safe) status of gelatin and stated that there
was no objection to the use of gelatin from any source and any
country provided that the hide from animals showing signs of
neurological disease were excluded and also specified raw
materials were excluded from the manufacturing process
• In the year 2000 the European Union approved the use of
gelatin
• In the lecture of Infusion and transfusion therapy by Dr.
Madách Krisztina, gelatin is used as an artificial colloid and is
used as an I.V. plasma expander with estimated time of 90-120
min and it has the smallest influence on homeostasis among
the artificial colloids such as: HES (hydroxyethyl starches) and
Dextran (40 Rheomacrodex, 70 Macrodex)*

The hypothesis of therapeutic effect of oral gelatin on
hair loss in both men and women
1. Gelatin exhibited one of the highest specific dynamic effects of any food which is
caused by increase peripheral blood flow. Increased blood flow had been shown
to increase the growth rate of some tissues in both animals and men.
2. Gelatin causes vasodilation of peripheral blood vessels therefore improving the
hair follicle blood circulation.
3. Gelatin is composed of 18 amino acids which are delivered via the blood stream
to the hair follicle which are the building blocks for hair follicle growth.
4. The hair follicle stays longer time in the anagen stages due to increase availability
of the amino acids provided by gelatin consumption.
5. Delaying the progression of the miniaturization of the hair follicle in androgenic
alopecia by mechanisms mentions above (1, 2, 3, 4).
6. It is possible that there are changes of signals with the milieu of amino
acids in gelatin, through change of proteins produced and released
within the hair follicle that promotes and stimulates hair growth in the
anagen stage.
The specific dynamic action of gelatin*
• As early as 1926, Rapport et al., discovered that gelatin
exhibited one of the highest specific dynamic effects of any food
• The increase in body temperature due to specific dynamic effect
was thought to be cause by an increase in peripheral blood flow
• This hypothesis is supported by an article in which finger blood
volume was found to increase following gelatin ingestion
• Moreover, increased blood flow had been shown to increase the
growth rate of some tissues in both animals and men

Identification of several food derived
collagen peptides in human blood after
oral ingestion of gelatin.
Healthy human volunteers ingested
gelatin hydrolysates 9.4g - 23g from
porcine skin, chicken feet and cartilage
and after 12h of fasting.
After oral ingestion the peptide form of
hydroxyproline
(Hyp)
significantly
increased and reached a maximum level
of 20-60 nmol/ml after 30-60 min and
then decreased to half of the maximum
level at 5h after ingestion.
The ratio of the peptide form of Hyp to
the free one was approximately 1:3.
Major constituents of food derived
collaged peptides in human serum and
plasma were identified as Pro-Hyp.
In addition, small but significant amount
of Ala-Hyp, Ala-Hyp-Glu, Pro-Hyp-Gly,
Leu-Hyp, IIe-Hyp and Phe-Hyp were
contained.

Results:
The therapeutic effect of gelatin-cysteine diet on growth of
human hair*
•
•
•
A favorable effect on the growth of hair has been reported in 1982, by Morganti et
al. effect of gelatin-cysteine diet supplement on growth of human hair. The study
was double blind, lasted 3 month, and involved 40 volunteers aged between 20-40
years.
The diet of the volunteers was 2 gram gelatin and 0.8 gram cysteine every day or
placebo (starch tablets).
The results of this study suggested that the dietary supplementation of gelatin and
cysteine combination promoted more intense hair growth and leads to substantial
increase in the diameter of the fibers 1-3.

Gelatin - cystine therapy in seborrheic alopecia*
•
•
•
In 1986, Padova et al.
published an article on gelatincysteine in seborrheic alopecia
in which, 60 Subjects (40
females, and 20 males) affected
by Seborrhea alopecia took
part.
Each volunteer took four
capsules a day for 3 month.
Every capsule contained 500
mg gelatin and 200 mg lcysteine (In total 2-gram
gelatin and 800 mg cysteine
daily).
The results were significant
reduction in seborrhea in 30%
of the subjects and significant
reduction in sebum level.

The therapeutic effect of edible gelatin in androgenetic alopecia:*
•
•
•
•
•
•
In yet another article by Morganti et al. he
reexamined the influence of gelatin with the
addition of cysteine and serenoa repens on hair
growth (serenoa repens is commonly known as
saw palmetto and sabal serrulatum, it is a small
palm tree, normally reaching a height of around
2–4 m).
The study was conducted for a long period
application of 50 weeks of a new cosmetic lotion,
on 48 volunteers (24 women and 24 men) aged
between 21 and 38 years, affected by
androgenetic alopecia (type 3 and 4 according to
Hamilton).
12 subjects also took a dietary supplement (4
pills per day) based on gelatin and cysteine. The
solution and the dietary supplement (placebo
and active) were assigned in a randomized
double blind manner.
Hair mass and the mean hair number were
controlled according to Price et al. exclusion
criteria included use of topical or oral drug or
diet supplement within the previous 6 months.
The obtained results showed an increase of hair
mass from 20 to 30% (p<0.005) together with a
contemporary increase of hair number (from 17
to 27%) (p<0.005) compared to the placebo for
subject using the lotion only.
With the diet supplement a further increase of
50% (p<0.005) in hair growth and significant
decrease of blood ROS (Reactive Oxygen Species)
were obtained.

Results of edible gelatin in the treatment of female pattern hair loss
• According to Dr. Zeev Pam clinical experience and observations:
1. the clinical results in TE are faster than in AGA.
2. In TE the recommended duration of the treatment is 3–6 months while in
AGA the clinical treatment is at least 12 months.
3. In females who have both TE and AGA the treatment time depends on
clinical results.
Results of edible gelatin treatment in male pattern hair loss
•
•
•
•
According to Dr. Zeev Pam, clinical experience the treatment for male pattern hair loss may
even be longer than 6 month with the dosage of 1.5-3 grams gelatin daily or even higher as
a gelatin tablet or as gelatin powder.
The recommended duration of the treatment in male pattern hair loss is at least 3-6
months of daily dosage of 1.5g-3g of gelatin .
He, theorized that gelatin supplementation is beneficial in the early stages of androgenic
alopecia by dilation of the peripheral blood vessels and supplying the necessary amino
acids for the hair follicle and delaying the worsening of the androgenic alopecia stages.
Dr. Zeev Pam, suggested that there is a beneficial results from the combination therapy of
gelatin with other methods such as: 1. LLLT 2. vitamins and other food supplements and
extracts such as: biotin, taurine, zinc, green tea, silica, grape seed, saw palmetto. 3. fatty
acids 4. drugs for hair loss treatment such as finasteride , minoxidil and topical revivogen.
