 Vitamin A, both beta-carotene and retinol, maintains healthy coat and skin, promotes bone growth, protects against infection, and aids in the treatment of eye disorders. vitamin a deficiencies result in night blindness, susceptibility to infections, dryness and itching, and poor growrh and development.
Vitamin B-l (Thiamine)The B vitamins are water-soluble but, as with all vitamins and minerals, do not go overboard. Vitamin B-l maintains normal function of the nervous system, and improves brain power in pets according to Wendell Belfield, DVM. |

 Please note that the provitamin carotene, which is converted by the body to utilizable vitamin a, cannot be toxic like animal-sourced vitamin a.
ALPHA LIPOIC ACID (ALA)
One of the most important antioxidants, although we need a variety of them, is alpha lipoic acid. ALA helps with a variety of problems, one of which is the cardiovascular complications of diabetes having to do with small-vessel damage from inflammation. We also use a proteolytic enzyme called Vitalzym X to neutralize and reverse this inflammatory process. |

 Originally they thought it was vitamin a that was responsible for bone health, but when they boiled it and destroyed the vitamin a, the anti-ricketic activity, that is the bone health activity, was still present in the cod liver oil. And so it was named vitamin D, because there had already been identified a vitamin a, a B and a C, so the next in line was vitamin D.
Adams: So this was many decades ago then?
Dr. Holick: This was back in the early 1900s. And then they realized that if you're exposed to sunlight, or artificial ultraviolet-B radiation, that it also had anti-ricketic properties, i. |

 Both alpha-and beta-carotene and beta cryptoxanthin are what's known as provitamin A carotenoids, which means that the body can convert them to vitamin a. As opposed to animal sources of vitamin a, these plant sources cannot deliver a toxic amount of the vitamin. (Interestingly, if you eat enough polar bear liver, which is extremely rich in so-called preformed animal vitamin a, you can die from a toxic dose of that vitamin. |

 But getting vitamin a in a natural form with a natural complementary base of nutrients, like you get in spirulina, is very different. I don't believe there's a very high risk at all of vitamin a toxicity, even if you're chowing down on very large doses of spirulina on a regular basis. And I submit my own experience as a demonstration of that -- I consume large amounts of spirulina, perhaps more than any person I know, and yet I don't show any of the symptoms of vitamin a toxicity at all. |

 I find it interesting that all fruits (see tables in the back) and vegetables contain vitamin a (actually beta-carotene, which is the precursor to vitamin a), which is a fat-soluble vitamin, along with fat—nature has made sure that the vitamin a is absorbable and assimilated because of the presence of fat. Also, fats are a source of essential fatty acids. These are needed for the proper functioning of the endocrine system that controls hormone production, growth, reproductive activity, production of vitamin B12 in the intestines, and for helping to make calcium and phosphorus more available. |

 Sufficient levels of vitamin a are particularly important for preventing parasites, as this vitamin seems to increase resistance to penetration by larvae. Good dietary sources of vitamin a include salad greens and properly cooked carrots, sweet potatoes, and squash. A combination formula of digestive enzymes, taken between meals, may also be helpful for eliminating parasite larvae or eggs in the intestines.
Certain foods are antiparasitic, according to Gittleman, and you should incorporate more of these foods into your diet. |

 Poor immunity, a reduced sense of taste and smell, night blindness, and dry skin and eyes, are signs of a vitamin a deficiency. The best food sources of vitamin a are animal and fish livers, kidneys, dark green and orange vegetables, egg yolk and milk. Beta-carotene is found in the yellow pigment of fruits and vegetables such as carrots.

| Inadequate intake of vitamin a, which is characterized by night blindness (i.e., difficulty seeing in the dark or adjusting to bright lights), is also associated with serious eye diseases. Take 25,000 IU of vitamin a (not beta-carotene) daily for thirty days, then reduce the dosage to 10,000 IU daily. If, however, you are a woman of childbearing age and there is any chance that you might get pregnant, do not take more than 5,000 IU daily.
To reduce your long-term risk of developing macular degeneration and cataracts, take 5 mg daily of lutein, either as lutein esters or unbound (free) lutein. |

 C Is for Collagen
Though not as well-established in the antiwrinkle business as vitamin a, vitamin C, a nutrient known for its importance in the manufacture of collagen, is being touted by some experts as a key player in keeping the complexion smooth.
"Vitamin C is essential for connective tissue in the body, particulatly for the layer where the collagen that maintains the integrity of your skin is made," explains Lonaine Meisner, Ph.D., professor of preventive medicine at the University of Wisconsin Medical School in Madison. |

 Further, since those who suffer from vitamin a deficiency suffer from malnutrition generally, increasing the food security and nutritional security of the poor—through increasing the diversity of crops and the diversity of diets of poor people who suffer the highest rates of deficiency—is the reliable means for overcoming nutritional deficiencies."41
Devinder Sharma "A majority of the acutely malnourished people that the proponents of "golden rice" claim they want to help cannot afford to buy rice from the market. |
| According to a Greenpeace report, golden rice provides so little vitamin a, "a two-year-old child would need to eat 7 pounds per day."31 Likewise, an adult would need to eat nearly 20 pounds to get the daily recommended dose.32
"This whole project is actually based on what can only be characterized as intentional deception," writes Benedikt Haerlin, former international coordinator of Greenpeace's genetic engineering campaign. "We recalculated their figures again and again. We just could not believe serious scientists and companies would do this."33
There are other considerations. |

| A deficiency of vitamin a will increase susceptibility to infection, as will deficiency of Vitamin D. Vitamin E protects the mucous membranes and can increase resistance to bacterial and yeast infections. Vitamins B6 and B5 stimulate the immune system,- a vitamin B6 deficiency is associated with depletion of white blood cells in the thymus, spleen and lymph nodes and lowered antibody production. Combinations of various vitamins with omega 3 and omega 6 oils regulate inflammatory reactions in the body. |

 However, deep sea shark liver oil does not contain large amounts of either vitamin a or D and is quite safe to consume. In this respect, it is important to note that other components of the diet, such as carrots and green leaf vegetables, are also a source of vitamin a, and sunshine or fortified milk can provide vitamin D.
The recommended daily allowance for vitamin a is 1000 retinol equivalents per day and for vitamin D is 400 International Units (IU). |

| Or, as Michael Pollan asks is his New York Times Magazine article, "The Great Yellow Hype," why not instead teach "people how to grow green vegetables [that are rich in vitamin a and other nutrients] on the margins of their rice fields, and maybe even give them the seeds to do so? Or what about handing out vitamin-A supplements to children so severely malnourished their bodies can't metabolize beta-carotene?"36 In fact, organizations are successfully doing these. |

Grains of Delusion "The main agenda for golden rice is not malnutrition but garnering greater support and acceptance for genetic engineering amongst the public, the scientific community, and funding agencies. Given this reality, the promise of golden rice should be taken with a pinch of salt. |

Fade 'Em Away with Retin-A
Originally developed as an acne medication to unplug clogged potes, Retin-A has found tesounding success as an anti-aging ointment. Though not a fountain of youth, Retin-A works to eliminate fine wrinkles, blemishes and age spots by stimulating cell turnover in a metabolic process that still is not entirely understood, says Retin-A cteator Albert Kligman, M.D., Ph.D. |
| It's a short hop from helping to hurting with vitamin a, says Dr. Lieber. But sticking to a multivitamin/mineral supplement with no more than 5,000 or 4,000 international units, as explained above, should give you the most benefit at the least risk.
Think Thiamin for the Brain
The unsteady gait, confusion and poor memory that many of us associate with someone who drinks excessively is just as likely to be caused by a lack of thiamin as by too much to drink.
"Thiamin is an important player in the way the brain works," explains Dr. Halsted. |
| Some researchers suspect
Deta-carotene, a precursor of vitamin a, is important in the pte-vention and tteatment of cervical dysplasia. But it's not the whole story. There are othet members of the catotenoid family—lycopene, lutein, zeaxanthin, beta-cryptoxanthin and alpha-carotene, for example—that may be equally important. Medical tesearchers say that many of these catotenoids, which ate responsible for the yellow and red pigments found in foods, may have healing properties.
Advances in technology have given scientists the tools to measure these carotenoids individually. |
| Others feel that the nutrients work by increasing the amount of vitamin a available to your cells.
"We've found that the antioxidant properties are important," says Dr. Palan.
Depending on supplements alone is not the best way to guard against cervical dysplasia, says Dr. Palan. That's because the fresh fruits and vegetables rich in cervix-protecting vitamins, particularly beta-carotene, may contain other beneficial substances.
But supplements can provide added benefits to a diet that already gets five servings of fruits and vegetables a day. |
