Still Ginned Up for Vitamin C

SightCGinned up:  To create or arouse feelings; move or excite.

After recently spending time with four of our most favorite vitamin-C- loving ophthalmologists, Dr. Richard Kratz, Dr. Tom Mazzocco, Dr. Paul Honan and Dr. Jerry Freeman, we are even more excited about the health benefits associated with mega-dosing vitamin C.

Additional discussions with one of our favorite researchers, Stuart Richer, OD, PhD, chief investigator of the Lutein, Antioxidant Supplement Trial (LAST), further gins-up our excitement over vitamin C.

Dr. Richer wrote his doctoral dissertation on Vitamin C. This gives him exceptional expertise on this subject so we listen carefully when he speaks about taking larger amounts of our favorite vitamin.

Unfortunately, humans do not have the ability to make their own vitamin C like most other mammals. Therefore, we must obtain vitamin C through our diet and from supplements. .

Vitamin C is required for the synthesis of collagen, the structural component of blood vessels, tendons, ligaments, and bone. It plays an important role in the synthesis of the neurotransmitter norepinephrine, which is particularly critical to eye and brain function. It is also required for the synthesis of carnitine, the chemical molecule essential for the transport of fat to cellular organelles called mitochondria for conversion to energy.

Mitochondria are responsible for producing the ATP energy required for cellular function, including in the retina. Mitochondrial diseases associated with the eyes include macular degeneration, retinitis pigmentosa, diabetic retinopathy, optic atrophy, cataracts, and drooping eyelids (ptosis).

We must mention that supplemental Vitamin C has also been suggested in a number of studies to have an inhibitory effect on carcinogenesis because of its free-radical scavenging activity against oxidative DNA damage.  It is suggested to control the transcription level expression of genotoxic metabolites that can lead to mutagenesis.

The few benefits we mentioned above are enough reason to dramatically boost the amount of vitamin C we receive from our diet and multiple vitamins.

Vitamin C Recommended Daily Allowance (RDA)

Unfortunately, the vitamin C RDA continues to be based primarily on the prevention of a specific deficiency disease called scurvy, rather than the prevention of chronic degenerative diseases and the promotion of optimal health. The current vitamin C RDA is only 90 mg per day for males and 75 mg per day for females.

The Linus Pauling Institute at Oregon State University reports that most of the information regarding vitamin C and the prevention of chronic disease is based on prospective studies that assess vitamin C intake in large numbers of people who are followed over time to determine whether they develop scurvy, not how it affects optimal health.

Food Sources- Six high food sources of vitamin C are:

Red peppers (282 mg per cup)

Kiwifruit         (150 mg per fruit)

Broccoli         (150 mg per cup)

Strawberries (82 mg per cup)

Citrus juice    (75 mg per cup)

Tomatoes       (45 mg per cup)

PEARL:  SightC+ is a powdered, high-potency, pH balanced, buffered vitamin C product for eye care professionals and their patients who feel the need to recommend or take extra vitamin C daily or occasionally, along with their daily full-spectrum multiple.

The Biosyntrx Team all use a scoop of SightC+ in water or juice twice daily to boost optimal health, particularly during flu and cold season. Mineral / Vitamin D buffered SightC+ replaces the need for a bone health supplement.
