LifeSource's Superior C 500mg contains the Vitamin C metabolite, Threonic Acid, which has been shown to enhance cellular uptake of Vitamin C.  This buffered, non-acidic Vitamin C supplement is superior as it also contains Alpha Lipoic Acid, an antioxidant known to help regenerate Vitamin C in the body.  Furthermore, studies suggest that Alpha Lipoic Acid may enhance the body's utilization of Vitamin C.  The addition of Bioflavonoids as synergists helps to create a well-absorbed, highly effective Vitamin C supplement. 

A better choice than Ester C!

When it comes to Vitamin C most of us know it for its benefits in the treatments of colds, flu and infections. But Vitamin C can be valuable in many other health disorders such as allergies, helping to detoxify histamine, wound healing - promoting and stabilizing collagen and as an antioxidant - scavenging free radicals and protecting cells from oxidation. But now there is another form of Vitamin C known as LifeSource's Superior C , which is involved in producing metabolites of Vitamin C known as threonic acid. These metabolites increase the viability of Vitamin C increasing the activity twice that of normal vitamin C.

The metabolics allows our Superior C 500 mg to work by:

• Increasing viability of Vitamin C
• Increasing the activity twice that of conventional vitamin C to utilize vitamin C for health and healing
• Stores in cells and tissues twice as long giving the body a greater opportunity to absorb vitamin C for health and healing

Absorbed approximately 4 times the rate of normal vitamin C

Has a P.H. level equivalent to distilled water reducing the possible occurrences or diarrhea and gastric irritation sometimes associated with high levels of Vitamin C. Ester C is combined with the Citrus Bioflavonoids which accompanies Vitamin C naturally in nature.

Vitamin C and It's Metabolites
By Richard Passwater, Ph.D.

Vitamin C metabolite, Threonic Acid Advanced vitamin C is quickly absorbed, reaches higher intercellular levels, and is excreted more slowly.

Recent research reports have increased our comprehension of what vitamin C does, how megavitamin amounts of vitamin C supercharge cells, and how a vitamin C metabolite increases the "potency" of vitamin C. These new findings will help us understand how megavitamin quantities of vitamin C can bring us "super health," and may even lead to better targeting of vitamin C in the body.

In January, the conservative Nutrition Reviews discussed (and this is their article title) "Ascorbic Acid Levels in Cells May Be Higher Than First Believed." Wow! Have they finally discovered that megavitamin doses are absorbed by cells and lead to greater activity than the meager RDA quantities?

In March, this respected journal reviewed additional functions of vitamin C in an article entitled "Vitamin C: Newer Insights into its Biochemical Functions.

In April, The FASEB Journal (the official publication of the Federation of American Societies for Experimental Biology) reported two studies shedding more light on the role of the vitamin C metabolite L-threonic acid. The first study showed that this acid increases the amount of vitamin C taken up by the T-cells of the immune system. The second study showed that L-threonic acid increases the action or "potency" of vitamin C. (L-threonic acid is available as a food supplement only in the patent pending vitamin C formulation from LifeSource Nutrition). Superior C 500 mg. from LifeSource Nutrition has a better testing result than Ester C.

Last June, a more detailed report of the role of this metabolite in potentiating the action of vitamin C in preventing scurvy was published in Life Sciences .

Master Nutrient

Many people call vitamin C "the master nutrient" because its actions are so extensive and so diverse. Vitamin C is involved in so many biochemical pathways that a deficiency can produce a multitude of disorders.

Physicians and scientists have long wondered how scurvy - a simple vitamin deficiency - can cause so much to go wrong in the body. The gruesome symptoms include loosened joints, bleeding gums, psychotic disorders, black and blue spots and broken capillaries, just to name a few which occur before death. Now we are beginning to understand: it is not only what reactions vitamin C is directly involved in, but also what it is indirectly involved in that's important to staying healthy.

Recently, we have begun to understand two additional functions of vitamin C. These functions re reviewed by Dr. Harish Padh he University of Chicago .

The first new realization involves vitamin C's role as an antioxidant in terms of protecting body components by scavenging free radicals. Now we're finding out that vitamin C is an antioxidant in the sense that it keeps the mineral portion of certain enzymes in their proper reduced electronic state.

Minerals such as iron and copper are key components of hundreds of enzymes. Enzymes control body chemistry, and nearly every type of reaction in the body requires a specific enzyme. Enzymes that depend on iron and copper won't work if these minerals are oxidized to a higher electronic state. What vitamin C does is to restore this required electronic state and thus rejuvenate oxidized enzymes.

Dr. Padh concludes, "The available data suggest that perhaps the most significant role of ascorbate is as a reductant that, along with other reducing agents, minimizes damage by oxidative processes. This role includes keeping the iron and copper ions of some enzymes in their required reduced form and in neutralizing harmful oxidants and free radicals."

With this new comprehension, we will be able to understand much more about how vitamin C affects such diverse body functions.

Cell Usage

When you add to this new comprehension that cells can hold and use more vitamin C than previously thought, all of a sudden we can begin to explain how megavitamin levels of vitamin C work.

The concentration of ascorbic acid in cells could be as high as several millimolar, considerably higher than previous estimates. This applies to human peripheral mononuclear leukocytes, B lymphocytes and T lymphocytes (T-cells).

The report also states, "The new data comes after learning that neutrophils appear to have both low- and high-affinity membrane transporters for ascorbic acid... Having two transport systems of different affinities and capacities gives cells the flexibility to respond and adjust to quite different extracellular concentrations of the vitamin."

The problem was that the old way of measuring vitamin C content and uptake of cells was wrong. The analytical methods were lacking speed and precision, and were less sensitive. Now we know that cells of the immune system can hold considerably more than once believed. In addition, we now learn that cells have two mechanisms of vitamin C uptake. There must be a reason! This will open the minds of more medical researchers.

Immune Function

As long ago as 1971, the importance of vitamin C to the immune system was known. Drs. Lawrence DeChatelet, Charles McCall and Robert Cooper reported vitamin C stimulated increased activity of white blood fells. Without copious amounts of vitamin C, engulfment of bacteria by white cells can take place, but they can't break down the bacteria as effectively.

Vitamin C Uptake

Vitamin C metabolite L-threonic acid or its calcium salt, calcium threonate (the form of L-threonic acid found in LifeSource's Superior C 500mg), increases vitamin C uptake of cells. Dr. Anthony Veriangierl of the University of Mississippi has studied this phenomenon in several ways. His recent study comparing calcium threonate with ascorbic acid confirms earlier studies showing that the metabolite makes vitamin C more potent, i.e., more ascorbate activity is provided within the cells. Essentially, with calcium, vitamin C has been shown to be absorbed more quickly, reach higher levels and is excreted more slowly. Now the studies confirm that the vitamin C uptake of the cells is greater with the metabolite L-threonic acid present.

Dr. Veriangieri has shown that adding L-threonic acid to ascorbic acid or calcium ascorbate results in the same improved vitamin C activity as provided with calcium threonate. Additionally, he has shown that in a special breed of laboratory rat called the Osteogenic Disorder Shionogi (ODS) rat, calcium threonate is four to five times more effective than ascorbic acid in preventing scurvy. This is the accepted method for measuring vitamin C activity.

The ODS rats do not manufacture vitamin C in their bodies. Thus, they have the same genetic handicap that humans do. For this reason ODS rats may replace guinea pigs for studying vitamin C.

The researchers concluded, "The results clearly show that, based on ascorbate activity equivalents, Superior C from LifeSource has more available ascorbate activity/potency than ascorbic acid (regular vitamin C)."

So, we are learning more about vitamin C and its uses all the time. Soon a multi-centered study of vitamin C and the immune system will be published that will change the way in which physicians think about vitamin C. This may really be an exciting year.
