Wolfberry
Improves Vision: A Rich Source of Beta-carotene
Chinese
people have been using wolfberry to prevent vision
degeneration or treat mild blurry vision for more than one
thousand years. Traditional doctors commonly used wolfberry in herbal
formulas. However,
wolfberry’s benefit to our eyes remained a mystery until
modern science discovered that wolfberry fruit contained
substantial amounts of pro-vitamin A: beta-carotene and
cryptoxanthin. Beta-carotene
has received most of the attention because Beta-carotene
generates vitamin A much more efficient than alpha-carotene.
Rich Nature Laboratories’ dried berry contains more than 28,000
IU/100g beta-carotene and Rich Nature concentrated
powder, W-LBP, contains 58,000-60,000 IU/100g beta-carotene.
Beta-carotene is now believed that has many health
functions on human body (see Table 1).

Best
known for improving visual system: provide necessary nutrient for retina
2.
Antioxidant
activity:
carotene exerts significant antioxidant activity compare
to that of vitamin A.
The antioxidant activity of carotene is probably
the factor responsible for the anticancer effects noted
in population study.
3.
Anti-aging:
Carotenoid content of tissue is the most significant
factor in determining maximal life span potential (MLSP)
of mammalian species.
For example, human MLSP of approximately 90 years
correlates with a serum carotene level of 50 to 300
micrograms per deciliter while other primates, such as
the rhesus monkey, have a MLSP of approximately 34 years
correlating with a serum carotene level of 6 to 12
micrograms per deciliter.
4.
Immune
system:
Beta-carotene appears to enhance thymus gland function
and increase interferon’s stimulatory action on the
immune system. Interferon
is a powerful immune-enhancing compound that plays a
central role in protection against viral infection
5.
Reproduction:
Beta-carotene has a specific effort in fertility
distinct from its role as a precursor to vitamin A.
The carotene cleavage activity changes with the
ovulation cycle, with the highest activity occurring
during the midovulation stage
6.
Best known
for improving visual system: provide necessary
nutrient for retina.
7.
Antioxidant
activity: carotene exerts significant antioxidant

Wolfberry
contains 18 out
of 20 amino acids, which serve as a building block
of proteins. Proteins
are now recognized as the predominant ingredients of
cells. The
20 standard amino acids also serve as raw materials for
the manufacture of many other cellular products, such as
enzymes, hormones, antibodies of immune system.
Several of these amino acids are key
intermediates in cellular metabolism.
Wolfberry
has all 8
essential amino acids.
Human
needs the essential amino acids to function but human
body cannot produce them.
The essential amino acids must obtain from food.

Anti-Mutation
from Wolfberry- China Studies:
Mutation
is the process whereby changes occur in the quantity or
structure of the genetic material of an organism.
Mutations are permanent alterations in the genetic
material, which may lead to changes in phenotype, or in other
words, it may lead to abnormal cell types, including tumors.
Two in vitro
studies have shown that the active ingredient, wolfberry
polysaccharides inhibit mutation.
The Ames test done by
Chinese scientists has demonstrated polysaccharides inhibit
2-AF induced TA100 mutation.
An increase in inhibition was observed when the dosage
of polysaccharides was increased (Figure 1).
