Aging is the common lot of all humanity. We are born, we
live, we get older and we die. Yet, some people age slowly, gracefully and
healthfully, while others age rapidly, with accompanying pain and debility.
Many factors contribute to our rate of aging: our genes, our
levels, our diet and exercise patterns, drug,
alcohol and tobacco abuse, etc.
Two extremes of aging are presented by progeriacs and the people of Yuzurihara,
Progeria is a disorder that usually appears between birth and 18 months of age.
It involves extremely accelerated aging. Progeriac children are bald, heavily
wrinkled, have cataracts and usually die by the age of 12 or 13.1
The residents of Yuzurihara are extremely long-lived and show little skin
wrinkling, even in old age. There are 10 times more people 80 and older in
Yuzurihara than any community in the United States and they usually are free of
typical age-related diseases and live active lives.1
Surprisingly, there is a specific connection between the accelerated aging of
progeria and the exceptional longevity of the Yuzuriharans. Children with
progeria excrete up to 17 times more
hyaluronic acid (hyaluronan, or HA) in
their urine than normal children.1 The residents of Yuzurihara, through their
unique diet, maintain high, youthful levels of HA throughout their long and
(HA) is a long chain molecule that consists of alternating units of
N-acetyl-glucosamine and glucuronic acid.2 Its molecular weight may range
from 50,000 to 4 million Daltons. HA can absorb up to
3,000 times its weight in water and is an important
hydrating agent for tissue.2
HA is found in virtually all
tissues and fluids of the body, especially in synovial (joint) fluid, the
eyes vitreous fluid and in skin.2 HA plays a critical role in maintaining
healthy joint synovial fluid and preventing the degeneration of aging joints.
has high daily turnover, so large amounts may be needed to maintain normal
steady-state levels. HA is also a regulatory molecule influencing cell movement,
phagocytosis and blood vessel formation.2 Hyaluronic acid also serves as a free radical
scavenger and antioxidant, and may be particularly important to protect the skin
from the aging effects of excessive sunlight exposure.2 HA is critically
involved in healthy wound healing.2 HA stimulates DNA synthesis and fibroblast
cell division, essential for healthy skin and cartilage maintenance.3 By the
time a person reaches age 30, his or her HA becomes disorganized from skin
collagen protein, compared to the interweaving of HA and skin collagen in a
nine-year-old, and is even more disconnected in the skin of 60-year-olds.4
Hyaluronan & Type II Collagen
Given the importance of HA for healthy skin and joints, its high turnover and
normal decrease with aging, an effective, absorbable source of HA is
highly desirable. Fortunately, a bioavailable source of HA is now available:
chicken sternum type II collagen.
BioCell Technologies has developed a patented, purified, enzymatically
hydrolyzed (partially digested) type II collagen supplement, derived from the
sternum (breastbone) of young chickens. This product provides at least 10
percent by weight of a low molecular weight HA, which is highly absorbable.
Native collagen, which has not been predigested, also provides HA, but in
the form of giant molecules that are too large for absorption. BioCell's
collagen molecules have a typical molecular weight of only 1,500 to 2,500
Daltons, and thus are easy for the body to absorb.
In February 2004 Dr. William Judy, senior scientist at SIBR Research, announced
the results of a double blind clinical study with Collagen Type II. In a
36-hour peak absorption study using a single dose, Collagen Type II HA
significantly increased in the blood at four hours after ingestion, and peaked
at a level 7,000 percent above the placebo controls levels in 12 hours.
28-day steady state bioavailability study using a constant daily dose, after
seven days the Collagen Type II HA levels became stabilized and remained so
throughout the study at a level 3,543 percent higher than controls. Thus,
regular use of Collagen Type II can be expected to provide a significant dose of
hyaluronic acid to supplement the age-declining tissue levels of HA typical of most people.
Type II Collagen
The benefits of type II collagen does not stop with HA. Type II collagen, the
collagen that makes up moveable joints, also provides a high level (typically 20
percent) of chondroitin sulfate (CS). CS is one of six glycosaminoglycans (GAG)
that help form the connective tissue of skin, tendons, cartilage, ligaments and
bone matrix.5 CS is the most abundant GAG in the body.5 Partially depolymerized
(i.e., shortened chain length) CS is an effective anti-inflammatory compound.6
CS also enhances the synthesis of HA and cartilage proteoglycans in
osteoarthritis patients, improving the quality of their joint tissue.6
Chondroitin sulfate also
inhibits enzymes such as collagenase, elastase and proteoglycanase that become
overactive in joint degeneration and skin aging, destroying cartilage and
Type II collagen also contains cartilage matrix glycoprotein (CMGP). CMGP
enhances the antioxidant protection within joints by carrying the essential
trace mineral copper to the chondrocytes. Chondrocytes are small cells
interspersed within the cartilage matrix of joints. The chondrocytes produce new
collagen and mucopolysaccharides to keep joints well cushioned and lubricated.
The chondrocytes also produce and secrete copper
SOD (superoxide dismutase), a
free radical-destroying enzyme that is critical to protect joint tissue from the
free radical damage that occurs as part of the process of joint degeneration.7
Duarte notes that various components of hydrolyzed type II collagen have
multiple protective benefits. Collagen II components 1) resist cartilage protein
digesting enzymes; 2) reprogram destructive chondrocytes to lessen inflammation;
3) promote new cartilage and proteoglycon synthesis; 4) enhance production of hyaluronic acid, producing a thick, effective, lubricating synovial fluid that protects and
cushions joints; 5) protect the surface of cartilage from oxidative (free
radical) damage and enzymatic digestion; and 6) act as powerful
Collagen Type II also provides 60 percent collagen protein. Collagen protein is
unique in containing the amino acids hydroxylysine and hydroxyproline. In a
study using hydrolyzed collagen, the subjects receiving collagen had
significantly higher blood levels of hydroxyproline than those receiving
placebo.10 As Moskowitz notes: The positive effect of the oral administration
of [hydrolyzed collagen] on skin and organs attached to the skin has been
observed for some time. These positive effects include improvement in nail
quality -- an effect on positive properties of hair and nail growth. And, in
veterinary studies, improvement in hair and hoof quality and growth.10
