Ceramides derived from wheat to replenish and nourish skin

Ceramides Nourish Skin From Within

Youthful skin is rich in ceramide molecules that nourish the skin matrix keeping it firm and supple. With age, our production of ceramides declines resulting in the loss of vital moisture.  Researchers have discovered a method to extract ceramides from whole grain wheat. Clinical studies document the ability of these ceramides to nourish aging skin from within and avoid the external signs of aging such as dryness and wrinkles.

When we are young, our bodies manufacture ample ceramide molecules to keep our skin healthy.1-3

These ceramides are a major component of our skin's surface. They protect against moisture loss to keep skin youthful and supple.4 Functionally, ceramides support the skin's matrix, keeping it firm.2,4

However, with age, ceramide production declines, and skin begins to sag and wrinkle.3

Scientists have found a way to extract ceramides from whole grain wheat that allows aging humans to nourish their skin's structure from within. Research has shown that ceramides derived from wheat inhibit the elastase enzymes that destroy the skin's elastin, which results in loss of flexibility and increased wrinkling.5 Natural ceramides provide continuous maintenance for skin and allow it to sustain its healthy protective function and vital moisture.

This article will examine the laboratory data on whole wheat-derived ceramides for restoring structure to human skin. Impressive clinical data show how supplementing with these ceramides produces smoother, more youthful skin free of the itching and flaking that is so common with age.2,3,6

Ceramides Preserve Youthful Skin

Aging causes a loss of ceramides naturally found in the skin. The result is thinning of the skin's outer layer that weakens the skin's moisture-retention properties.4

The obvious solution is to replace those ceramides.

But what is the best way to do so?

Laboratory research reveals some improvement to skin's moisture barrier function when lipids, including ceramides are applied directly to skin.4,7 But this topical approach can't match nature's steady supply of ceramides from the inside.

On the other hand, very promising studies show that ceramides, taken as a food supplement, can significantly improve skin moisture levels and reduce the discomfort of dry, aging skin.

Until 1997, ceramides for internal use were derived only from animal sources, chiefly from cows.4 Researchers have discovered a number of plant-based ceramides that are available from grains such as rice, corn, and wheat.4

A little over a decade ago a French company decided to explore the potential of wheat-derived ceramides for use as a skin moisturizer that could be taken orally. This would allow the ceramides to reach the skin's outer layer in a natural fashion, being delivered by the bloodstream and gently nudged into the extracellular matrix, where they would restore the healthy moisture barrier function of the skin.4

That same company went on to develop the first ceramide-rich extract of wheat. They used exclusively whole-grain, non-genetically modified wheat as the raw material.4,8 The new wheat extract contains purified oils, and has been tested to prove that it has no gluten or other allergy-provoking components.4

The product was an instantaneous hit in Japan, where since 1997 it has been used in many popular "beauty drinks" and nutritional supplements.4 A number of interrelated studies have now validated that healthy consumer response.4-6

Several early laboratory studies demonstrated that a powdered form of the wheat extract, which is equally potent as the oil form, could hydrate and restore youthful structure to human skin after being subjected to disruption of its protective barrier function.5 In addition, this study found a substantial reduction in free radicals in the skin, and showed that the wheat extract could inhibit the elastase enzymes that ordinarily would destroy elastin and contribute to loss of flexibility and increased wrinkling.5

Clinical Trials  

Human Clinical Trials

Clinical studies with the wheat ceramide extract began in 2005, after an encouraging pilot study.6 Women with dry to very dry skin received either a placebo or 200 mg/day of a powdered form of the wheat ceramide extract; treatment continued for 3 months.

There was a significant improvement in skin hydration as evaluated three ways, by a machine, by a dermatologist's examination, and by the patients' own subjective scores.6 Furthermore, women in the wheat extract group, but not the placebo group, experienced a significant reduction in dry patches, roughness, and itching. These effects are exactly what one would expect as the ceramides made their way through the bloodstream to the skin.

A second, larger study was then done to evaluate the wheat ceramide extract in its oil form.

In that study, women with dry to very dry skin took 350 mg of the wheat ceramide oil, or a placebo, daily for three months, in a randomized, double-blind fashion.4 Again, a series of different measures was used to determine the impact of the supplement.

Skin hydration was objectively measured by a technique called "corneometry."4 By this measure, the supplement (but not the placebo) significantly increased skin hydration of the arms, legs, and overall, with the greatest impact on the arms, where skin hydration had increased by more than 35%, compared to less than 1% in the placebo group.4

Subjects also rated their own perceptions of the effects of the treatment (supplement or placebo). At all measurement points in the study, the wheat extract scored better on the following measures: roughness, uniformity of complexion, facial skin hydration, leg skin hydration, suppleness, itchiness, and overall state of the skin.4

No significant adverse effects or side effects were reported, and the supplement proved slightly superior to the placebo in terms of acceptability.4

This study was a compelling demonstration of the power of a whole-grain wheat ceramide supplement to improve many of the essential features of the skin's barrier function, features that are typically lost to aging and environmental exposure. Simply put, women who supplemented with this product experienced measurable improvements in "beauty from within."

Maintain Youthful Skin Hydration and Integrity With Ceramides

  • With aging, skin loses its youthful moisture, suppleness, and smoothness, thanks to the loss of essential ceramide molecules.
  • Skin ceramides make up 35-40% of the lipids in the extracellular "cement" that binds together protective cells in the outermost skin layer, the stratum corneum.
  • Loss of skin ceramides renders aging skin permeable to moisture, leaving skin dry, rough, and itchy; ceramide loss is also a major contributor to wrinkles.
  • Ceramide replacement by nutritional supplementation is now a reality, the result of intensive research into the properties of ceramides in whole wheat grains.
  • Supplementation with wheat ceramides has been shown to restore ceramide concentrations in the skin while battling other factors that contribute to skin aging.
  • Clinical studies show that wheat ceramide supplementation measurably enhances skin moisture and contributes to smoother, more comfortable skin.
  • Wheat ceramides offer the first scientifically proven means of enhancing beauty from the inside out.


The centuries-long quest for "beauty from within" is now a reality, thanks to oral supplements derived from the whole wheat grain. A wheat-derived supplement rich in ceramides, which form 35 to 40% of the "cement" in skin's outermost layer can restore moisture and reduce dry, flaky, itchy skin.

Ceramides and other rare lipids are natural constituents of the wheat grain. By taking these compounds internally, skin can be nourished naturally, delivering ceramides directly to skin through the bloodstream, where they are taken up and deposited into the barrier layer, or stratum corneum.

Boosting your skin's ceramide levels can bring back its natural moisture levels yielding a healthy and youthful complexion — from the inside out! •

How Your Skin Ages

Skin is a complex, multilayered organ with a myriad of functions. The most visible manifestations of skin aging occur mostly in the outermost layers.

To understand how aging changes your skin, we need to review the normal structure of the outer layer of skin, called the stratum corneum, and what becomes of it over time.

The stratum corneum is composed of flattened, hard, dead skin cells that resemble overlapping bricks, which start as living cells in the lower skin layers. As they are pushed closer to the surface, they flatten out and die, providing a thin but very tough barrier.9

But these flat cells would flake away immediately if they weren't held together by a kind of flexible skin cement, which is 35 to 40% ceramides.4 If you think of the stratum corneum cells as bricks, the skin cement is the mortar between them that holds them in place.

Together, these flat cells and the more flexible, lipid-rich cement provide a natural seal that acts as a two-way barrier: it keeps out germs, toxins, and other contaminants, while keeping in moisture to maintain a healthy, flexible, and supple skin texture.10

Cells in the stratum corneum are constantly replaced from living cells in the deeper skin layers; the outer layers of skin (ie, epidermis) are replaced roughly every 39 days.11 And the ceramides and other lipids in the extracellular matrix are constantly replenished by nutrients brought to the deeper skin layers by the bloodstream.12

At least, that's how it all works in youth.

As we age, our skin, like so many of our other organs, slows down. Studies show that after age 50 or so, new outer layer skin cells take more than 50% longer to reach the surface, an indication of delayed proliferation.13

Worse, the amount of specialized lipids in the extracellular matrix declines with age and ceramides are among the first to go.1-3 As a result, the "cement" that holds the skin cells together is weakened and loses much of its moisture barrier function.2 Lost moisture results in the dry skin that is common in older adults.2,14

Finally, the skin, like every other organ, falls victim to the ravages of chronic oxidant stress and inflammation.15 Together these omnipresent threats trigger production of enzymes that degrade vital skin proteins. Among their chief targets are collagen, the main structural skin protein, and elastin, which gives skin its suppleness and flexibility.16 Chronic exposure to sunlight aggravates these processes.3,17-19

One look at a typical older person's skin tells the story. Lost moisture in the stratum corneum leaves the skin surface pale and dry with fine wrinkles.3 Inflammatory changes can produce itching, redness, and dry patches.Loss of collagen thins the skin, while declining elastin renders it less flexible; these changes produce the larger wrinkles we associate with age.20-22

While topical products aim to replenish skin oils from the outside, the skin's natural sealing agents such as ceramides and other specialized lipids, come from inside the body. They're derived from precursor molecules delivered by the bloodstream, that then make their way up through the deeper skin layers, ultimately being deposited in the stratum corneum.12 No matter how good your topical skin cream or lotion is, it cannot replace the structural barrier created by ceramides.
