Beta carotene is one of a large class of phytochemicals known as
carotenoids. In addition to beta-carotene, the carotenoids include
gamma-carotene, lutein and lycopene. They are particularly abundant in
green leafy vegetables, carrots and some fruits. Carotenoids were once
simply considered to be plant pigments that possibly performed some
auxiliary function in photosynthesis (the primary plant pigment
responsible for photosynthesis being chlorophyll).
In recent years, carotenoids have become increasing recognized for their
significant health benefits. Beta carotene is one of the most potent carotenoids. A powerful scavenger of free radicals, many studies suggest
that the antioxidant properties of beta carotene may be of benefit in
the prevention of cancer.
Beta carotene can be classified as a "pro-vitamin" and is converted by
the liver (of dogs and humans) into Vitamin A. Beta carotene
supplementation is believed to be less likely to cause toxicity than
Vitamin A supplementation, which is fat soluble and can build up in the
body's lipid stores.
Beta Carotene is believed to protect the mucus membranes that line the
respiratory and digestive systems. It also has a synergistic effect with
Vitamin C, helping protect it from oxidation and enabling it to perform
its own functions at peak efficiency.
Numerous supplementation studies have shown measurable cancer prevention
levels. Admittedly, other studies have shown that beta carotene doesn't
reduce cancer incidence in people that smoke or drink excessively. If
your pet is not indulging in tobacco or alcohol, beta carotene
supplementation should greatly benefit them. :-) |
