Wheat
has been called the staff of life, and the oil from the germ of the
wheat has long been used by people with a variety of health concerns.
The PDR
states, “Wheat germ oil protects and nurtures the skin, is a laxative
and reduces lipids. It is a valuable dietetic because of the high level
of polyunsaturated acids and vitamin E” [1]. Chinese medicine uses it
for night sweats, whereas “Flatulence, constipation, itching, and
menorrhagia are indications for use in Indian medicine” [1].
Royal
Lee advised its use for those who bruise easily (capillary fragility),
have lowered metabolism, have anoxia-like symptoms (frequent
sighing/yawning, tachycardia, hyperirritability), have tissue concerns
(bleeding gums), have low stamina, are obese and/or have cramps brought
on by exertion [2]. He also wrote, “Wheat germ oil is about 75%
unsaturated fatty acids and as such is believed to have an effect on
iodine metabolism, acting to increase thyroid activity in this respect.
This may account for the relief of fatigue often expressed by patients
using wheat germ oil in the diet” [2].
Some doctors also report that they use wheat germ oil for those with depression.
Recent
research confirms that wheat germ oil can help reduce oxidative stress
[3]. Wheat germ oil also contains policosanol (a substance that can be
helpful in lowering raised blood sugar and/or cholesterol levels
[4,5]), as well as octacosonal (a substance reported to improve human
fitness [4,5]).
One study reported, “Policosanol (PC) is
the common name for a mixture of high molecular weight (20-36 carbon)
aliphatic primary alcohols, which are constituents of plant
epicuticular waxes. Wheat germ oil has been reported to improve human
physical fitness, and this effect is attributed to its high PC,
specifically its high octacosanol (OC) content” [5].
Octacosanol
is a component of wheat germ oil and is sometimes advised for
Parkinson’s [4,6]. “There is limited evidence that octacosanol itself
may lower cholesterol levels…There are claims that octacosanol is
useful in building muscle strength and endurance, and these claims have
made the supplement popular with some body builders. There is
preliminary evidence, limited to animal experiments, that octacosanol
may increase voluntary exercise in the animals [4].
Wheat
germ oil naturally is high in the steroidal esters betasitosterol and
campersterol. “Beta-sisterol itself is used as a medicine in Europe for
BPH” (benign prostate hypotrophy) [4]. Interestingly, while three
studies using non-purified beta-sisterols found that it tends to
improve urinary output (and at the same time reducing mean residual
urinary volume for males with prostate problems), one study suggested
that using purified beta-sisterol “did not help flow volume” [4]. Of
course, Wheat Germ Oil E TM does not contain “purified” betasitosterol, but the naturally-occurring non-purified form.
Vitamin E
Wheat
germ oil is one of the most concentrated natural sources of vitamin E.
According to the US Department of Agriculture,
wheat germ oil contains vitamin E in the form of alpha-tocopherol
[7]. According to the 10 th edition of Modern
Nutrition in Health and Disease [8], alpha-tocopherol is an active form of Vitamin E.
Most vitamin E sold is not Food. Natural vitamin E “as found in Foods
is [d]-alpha tocopherol, whereas chemical synthesis produces a mixture
of eight epimers” [9] (natural vitamin E has recently been renamed to
be called RRR-alpha-tocopherol whereas the synthetic has now
been renamed to all-rac-alpha-tocopherol, though supplement labels
rarely make this clear; on supplement labels d-alpha-tocopherol is
generally ‘natural’, whereas dl-alpha-tocopherol is synthetic [10]).
Natural RRR-alpha-tocopherol has 1.7 - 4.0 times the free radical scavenging strength of the other tocopherols, RRR-alpha
tocopherol has 3 times the biological activity of the alpha-tocotrienol
form, and synthetic vitamin E simply does not have the same biologic
activity of natural vitamin E (some synthetic forms have only 2% of the
biological activity of RRR-alpha-tocopherol) [10]. The biologic
activity of vitamin E is based on its ability to reverse specific
vitamin E-deficiency symptoms [10], therefore it is a scientific fact that, overall, synthetic vitamin E has less ability to correct vitamin E deficiencies than Food vitamin E.
There is an interesting reason for this, which is that the body
regulates plasma vitamin E through a specific liver alpha-tocopherol
transfer protein, whereas it has no such protein for other vitamin E
forms [10]. Or in other words, the liver produces a protein to handle
vitamin E found in Food (like Wheat Germ Oil E TM), but not for the synthetic forms!
Even
mainstream researchers teach, “Vitamin E is the exception to the
paradigm that synthetic and natural vitamins are the equivalent because
their molecular structures are identical...Synthetic vitamin E is
produced by commercially coupling trimethylhydroquinone (TMHQ) with
isophytol. This chemical reaction produces a difficult-to-separate
mixture of eight isomers” [11] (vitamin E, of course, is not the only
exception--all nutrients are better if they are Food).
Isolated natural vitamin E has been found to have twice the
bioavailability as synthetic vitamin E [12]. The form of vitamin E
found in Food has been found to be 2.7 times more
retained in the body than a synthetic form [13]—this appears to be
because the body attempts to rid itself of synthetic forms as quickly
as possible [13]. Vitamin E-containing wheat germ oil been shown to
quench free radicals (antioxidant ability) [3] yet so-called “natural”
vitamin E forms (like succinate) do not--Even the PDR notes,
“d-Alpha-Tocopherol succinate itself has no antioxidant activity” [4],
so why would anyone want that for their vitamin E supplement?
Vitamin
E is necessary for the optimal development and maintenance of the
nervous system as well as skeletal muscle [8,11]. Vitamin E deficiency
can lead to certain anemias, nutritional muscular dystrophy,
reproductive problems, and hyperlipidemia [9]. Vitamin E has been shown
to reduce the risk of various cancers, coronary heart disease, cataract
formation, and even air pollution [10,11]. It also is believed it may
slow the aging process and decrease exercise-induced oxidative stress
[10,11]. Artificial fats seem to increase the need for vitamin E [14].
“RRR-α-tocopherol is especially high in wheat germ oil” [8]. “Probably
the most important source of α-tocopherol in the United States is the
supplement pill” [8]—that being the case, shouldn’t Food vitamin E be the preferred form?
Wheat Germ Oil E
TM naturally has antioxidant abilities, octacosanol, polyunsaturated
fatty acids, and a variety of substances shown to be beneficial for
health. Wheat Germ Oil E TM) is the product to consider when looking for the benefits these substances provide.
Note: This FOOD
brand product contains wheat. Those with wheat sensitivities should be
cautious about taking this product (although since it has no
significant amount of wheat proteins or carbohydrates [1], it may be
tolerable for those who are sensitive to those components). The PDR
states, “No health hazards are known in conjunction with the proper
administration of designated therapeutic doses” [1]. Note: For
constipation, the PDR advises doses up to 80 g per day (taken with meals and plenty of liquids) [1], but this amount is rarely needed.
