Natural Vs. Synthetic Vitamins

How They Are Different and How to Tell Them Apart

Did you know...

• that the vitamins you are now using are very likely synthetic?
• that synthetic vitamins have only one component out of a whole family of micro-nutrients that accompany them in their natural state?
• that only 50% of a synthetic vitamin can be utilized somewhat efficiently?
• that some sensitive people may actually have an adverse reaction to the synthetic vitamins?
• that scientists can chemically reproduce sea water but when you put fish in this synthetic sea water they die?

Is the World Flat?

At one time many respectable people were mislead to believe that the world was flat. This view was based on what were believed to be very good reasons(for example, the oceans never over-fill, the watermust be running off the edge...).  Today many respectable people insist that synthetic and natural vitamins have identical molecular and chemical structure.  Thus, they insist that synthetic vitamins are just as effective as natural vitamins.  Is this reason sufficient basis to form a pro-synthetic judgement?

In the laboratory, chemists can duplicate sea water that is chemically identical to natural sea water, but if you put fish in this synthetic water they will die.  Obviously, there is a life-supporting difference between natural and synthetic.

Natural or Whole Food Supplements vs. Isolated Chemical Compounds

When we say natural or whole food supplements, we're speaking of products that contain the total complex family of micro-nutrients (known and unknown) just as they are found in nature.  These micro-nutrients are indispensable for proper vitamin absorption and maximum utilization.  That's the only way you can have optimum nutrition.  Synthetic vitamins lack this wonderfully marvelous supporting family.For example, chromium is a mineral that is not prevalent in the American diet because it is missing from the soil in this country.  In it's natural state, chromium is a glucose tolerance factor or GTF and it helps protect us against diabetes.  But GTF is not really just one factor.  It's a whole family of factors.

Almost all chromium products on the market are from chromium picolinate, which is a single isolated compound that is made in the laboratory.  Chromium picolinate does not contain the glucose tolerance factor.  And yet, GTF is the main benefit of the natural micro-nutrient chromium.  So, it doesn't make sense to take the isolated synthetic chromium.  You are not receiving expected health benefits.  You might as well be throwing your money away.

Most micro-nutrients are found in families like those in chromium.  Another example is beta-carotene.  Almost all of the beta-carotene on the market is an isolated synthetic compound made from acetylene gas.  It's no wonder that some of the testing done with the synthetic form of beta-carotene has produced mixed results, and in one study on smokers, produced a negative result.

In nature, beta-carotene is part of a family of carotenoids.  It is never found alone.  For example, carrots and tomatoes have alpha-carotene, beta-carotene, cantozantheen, gamma-carotene, omega-carotene, etc.  And although beta-carotene is a great antioxidant, cantozantheen is already known to be an even more effective antioxidant.  In other words, by isolating beta-carotene from its entire family of carotenoids the experts have taken away an even more beneficial antioxidant.The B vitamins are another good example.  In 1925, there was only one known B vitamin.  By 1975, ten other B family members had been discovered, bringing the total number of B factors to eleven.  There's no telling how many more will be discoveed by the year 2025.If you had taken an isolated synthetic B-1 compound in 1925, you would have missed all the rest of the B family factors, which all work together to counteract stress.  But if you had used a whole food supplement like the Neo-Life B-Complex or Liver + C, you would have gotten all the known and unknown B vitamin factors, and that includes everything that won't be discovered until the year 2025!Like chromium, beta-carotene and B-complex, most nutrients are found in complex groups.  Amino acids, vitamin E, trace minerals and vitamin C all come in families.  Neo-Life keeps this family integrity intact with the most natural, the most researched, the most proven effective whole food supplements in the industry.  So, with Neo-Life, you're not only getting the isolated vitamin, but you're also getting all of the other known and unknown factors, just as nature intended.  And, you know it's not nice to try to fool Mother Nature!

Biological Activity Reduced 50%

Proponents of synthetic vitamins might claim natural and synthetic are equally effective; but when it comes to Vitamin E, that natural form is internationally recognized to be more biologically active than the synthetic form.  The biological activity is reduced by 50%, even to 70% in synthetic form.
Doubt has also been cast on other synthetic vitamins and their biological activity by Isobel Jennings of Cambridge University.  "The synthetic vitamins may be identical with naturally occurring substances or closely related.  The close relations, althought useful in many ways, pose some problems in that they may have only a fraction, whether large or small, of the biological activity of the natural products ... Synthetic vitamins may perform some of the functions of their natural counterparts while being useless for others.  But what may be more important is the fact that synthetic vitamins, prepared from chemicals instead of nature, are frequently less active biologically than their natural counterparts, thereby reducing any beneficial effect they may have."

Polarized Light, A True Reflection

The difference between synthetic and natural vitamins becomes apparent when viewing their response to a beam of polarized light.  The light when passing through a natural vitamin will always bend to the right due to it's molecular rotation.  Thus the letter "d" (representing "dextro" which means "right") often appears on labels.  However, the same light ray when passing through a synthetic vitamin will split into two parts, one part bending to the right and the other to the left.  Because the synthetic vitamin is half "dextro" (right) and half "levo" (left), the letters "dl" often appear on labels at the beginning of the synthetic name.
A synthetic vitamin is like the image in a mirror.  It looks like the real thing but doesn't function like the real thing.  Half of it will work in the body and the other half won't work as well.  Dr. Charles Schneider, Ph.D., professor of Chemistry, University of Cincinnati concluded wisely, "Get the vitamins that say natural.  There is a difference.  The "dl" (synthetic) will be cheaper, but if you could figure it out per energy unit or per use, the natural one will be cheaper."

Which would you rather have, the food in the mirror ... or the real food?

Safety

Medical findings indicate that synthetic substances may cause reactions in chemically susceptible individuals.  Interestingly, the same individuals can tolerate naturally derived vitamins.

When is Natural REALLY Natural?

Did you know that most vitamins on the market claiming to be natural only have to be 10% natural to make this claim!  If you decide to spend your hard-earned money on natural, it is critically important you learn to read labels to assure receiving your money's worth.

A product can even be 100% organic and not be natural at all.  To be called organic a molecule need only have at least one carbon atom.  This definition broadens the range from acceptable food sources of animal and plant tissues to raw materials including coal tar and wood pulp (yum!).  Many synthetics are made from coal tar derivatives.  That's the same stuff that causes throat cancer for tobacco smokers.  Don't you think your body can tell the difference?  Surely your cells can make a distinction between food and coal tar, just as a fish knows the difference between natural and synthetic sea water.

skydog

Many so-called natural vitamins have synthetics added to increase potency, or to standardize the amount in a capsule or batch.  In addition a salt form is added to increase stability of the nutrient (i.e. acetate, bitartrate, chloride, gluconate, hydrochloride, nitrate, succinate).  These terms added to the vitamin name help you identify synthetics.

Generally speaking, you can identify natural by reading the label and finding a listed "food" source such as citrus, yeast, fish, vegetable, etc.  If a chemical is listed or the source is blank, it is synthetic.

The synthetic vitamin dealers would like you to believe that there's no difference between natural and syntheric, because synthetic vitamins are much cheaper to make and mean much more profit for the company.  They are not efficiently utilized in the body as natural supplements due to the "dl" factor and the lack of complete families which include all surrounding micro-nutrients.  It's your choice!

ASK YOURSELF WHY:
Do I Need Supplements?
ARE YOU...

    having all of the energy you need to enjoy life to it's fullest?
    listening to your body give you signs that you are giving it what it needs to run efficiently?
    thinking ahead and concerned about protecting your future health and well being?
    under stress from today's fast pace?
    wanting to protect yourself from the environmental pollution surrounding us?
    concerned about the possible genetic trends revealing themselves in your family's ongoing health history?

        Then your answer could be yes, I need a supplement.

Did You Know...

    that possibly 95% of all diseases are degenerative?
    that scientific evidence links nutrition to disease prevention?
    that likely 80% of all cancer comes from environmental pollution (the air we breath, the water we drink, and the chemically tainted foods we eat)?
    that the average American consumes 6 pounds of artificial chemicals a year?
    that the housewife is the person most at risk from these dangers?
    that maybe 15% of all Americans are in vital good health?

WHY CAN'T I GET WHAT I NEED FROM THE FOODS I EAT?

    The foods you eat are stripped of nutrients through refining and processing.
    The foods you eat are laden with fats, sugars, and salts, and devoid of other essential nutrients.
    A USDA government survey of 21,500 people found that not one single person consumed 100% of the U.S. RDA, from the foods they ate.
    Due to the time it takes fresh foods to get from the farm to your table, 57% or more of the nutritional value can be lost.
    The foods you eat can be harmful from the use of pesticides, fungicides, sulfites, and preservatives.

Is There A Solution?

YES, you could eat freshly picked, organic foods, grown in soil that has been re-mineralized, then served raw or slightly cooked, in a way that is as close to their natural form as possible. You would also need to eat whole grain breads/pastas made from flour ground fresh daily. However, few of us can spend our entire day hunting, gathering, and carefully preparing our food!

Is There A More Practical Solution For Today's Lifestyle?

YES, you can supplement your diet with the most natural, most organic supplements on the market. This is not an excuse for a poor diet, but supplements can definitely help.

We want you to have an unbiased way to determine whether your vitamins are natural or synthetic. The following list, "How to Read Labels," will help you determine what you are paying for with your hard earned money.

Today there are two main categories of vitamin supplements generally available
commercially. They are as follows:

1. Supplements containing chemical vitamins (such as USP man-made vitamins or
nutrients) added to a natural base. This category is related to the direct addition of
synthetic vitamins and nutrients to a product and represents a majority of the supplements
and fortified foods available today.

2. "Food Grown" or "Food Based" supplements. In this category, product potencies are
often derived by adding (spiking) chemical, synthetic vitamins and nutrients into a base
such as yeast, algae, other bacteriums or a mixture of various materials and then using
that artificially potentized (spiked) material base or a portion of that base for all or part of
the labeled potency of the product. These labeled products may have a generally
misleading label claim referring to the spiked base as the “food” source. (This category
represents the indirect addition of synthetic vitamins and nutrients). The indirect addition
of synthetic nutrients, in this case, is apparently for label claims of “Food Source” which
can be legally made if the base that the synthetics are added to (spiked into or “grown”
within such as yeast or other materials) is referred to as natural “food.”

从这里拿来的一个段落：

希望以后有类似NOS的标准出现：

×××××××××××××××××××××××××××××××××××
The establishment of the NOS will help to create a new category of NOS vitamin and
nutrient food supplements which represent a food inherent, naturally occurring vitamin
and/or nutrient food supplement, bulk food material or fortified food with labeled potencies
derived only from food and botanical extract sources with related, labeled and assayed
potency values.

All NOS supplement potencies, as labeled, will be derived directly from food and botanical
concentrates with a minimum quantitative standard. The NOS certification cannot be
issued if synthetic vitamins, inorganic minerals or synthetic nutrients of any kind have been
added to the NOS supplement applicant product either directly or indirectly.

    这个我没有做过研究，抱歉.....

相信绝大多数是synthetic的。一小粒包含很多维生素的都是synthetic的，通常natural occuring的都是大大粒capsules，一次几粒的，但是有些synthetic的也是叫人吃多多粒，所以很难知道。可以看标签上的成份，在马来西亚，我对这些公司不是很放心。我会在美国或者纽西兰买，因为那里的法律比较完备。奸商比较难做鸡鸣狗盗的事。

我找supplements，会先制定那种有自然来源的，然后找公司来源与其提炼过程。像Pycnogenol，他们只用DI water就可以提炼了，没有其他有毒化学原料来提炼。

有些便宜的b-complex是用石油提炼出来的，所以大家要多加小心。

Natural versus Synthetic Vitamins

Many manufacturers may attempt to duplicate a vitamin found in nature, however there is still the missing link that naturally holds it together. Scientists may have or know of all the chemicals that make up a tomato seed, however are they able to create the seed itself?

Natural vitamins contain something that no synthetic can duplicate. It is the missing link which is not found in any synthetic vitamin that gives a natural vitamin it's "god created" qualities.

You are constantly bombarded with vitamins are all the same.

We are often told, "A vitamin is a vitamin." But there is a big difference between synthetic and naturally derived vitamins. The discoverer of Vitamin C noticed this difference when testing his discovery. In 1930's, Dr. Albert Szent Gyorgyi was awarded the Nobel Peace Prize in medicine for discovering Vitamin C.

A friend of his who was suffering from a debilitating disease was given Vitamin C and did not recover, he did recover when he consumed food that contained a high vitamin C content. Dr. Albert Szent Gyorgyi would spend the rest of his life trying to discover why naturally produced Vitamin C worked and man-made did not.

Many people are allergic to the chemicals used as a base for synthetic vitamins. Some are toxic, including nicotine and coal tars. If the product is in a natural state then man-made toxins will not be present. Many synthetics are made from coal tar. Coal tar contains benzoapyrene, "A yellow crystalline carcinogenic" [1].

Vitamin E is another good example of a nutrient that has fallen victim to the synthetic spell. On a supplement label, natural Vitamin E is listed as d-alpha tocopherol, d-alpha tocopheryl acetate, or d-alpha tocopheryl succinate. ynthetic vitamin E on the other hand are labeled with a dl-prefix.

Studies have shown that natural Vitamin E absorbs much better then synthetic versions. Protein chaperones produced in the liver select the natural d-alpha form of Vitamin E and largely ignore the rest.

One study in particular showed that after 23 days of supplementation, natural Vitamin E levels rose higher then synthetic levels[2]. This study also showed that the blood and tissue levels of natural Vitamin E rose twice as high as the synthetic.
Synthetic Vitamins and Adverse Reactions

Are the use of synthetic vitamins in studies the reason why adverse and sometime dangerous reactions are occurring?

Consider the "death warning" by Johns Hopkins on Vitamin E. A review of the articles on the results of this study did not disclose the fact that most of the studies were done using the synthetic (dl-alpha-tocopherol) rather than the natural (d-alpha-tocopherol) form of alpha-tocopherol[3].

Organic foods are the best source of vitamins and minerals. Fresh organic fruits and vegetables, nuts and seeds and unprocessed grains are a very good source of these life giving nutrients. Since so few of us consume foods genuinely fresh and unadulterated, practically all of us need to supplement our diets with nutritional supplements.

Getting the nutrients we need from our food supply just doesn't happen in today's over processed world. Fruits and vegetables are being grown in chemical fertilizes, pesticides and waste contaminants. They're often coated with toxic chemicals. They're harvested and forced ripened with a gas causing catastrophic nutritional loss.

US Senate Document #264 states that "99% of the American people are deficient in minerals and a deficiency in any one or more important minerals actually results in disease."

Supplementing your diet with the right nutrients is a safe way of providing your body with its nutritional needs.
