You see, there are two types of iodine necessary for optimal nutrition and thyroid function: Iodine and iodide. The iodine supplements you normally find are made from kelp – a seaweed – lacking in iodide. Plus, the iodine supplements on the retail shelves are about 100 times too weak to be effective.
Low iodine can lead to low energy and weight gain, along with a busload of other problems.
It’s that straightforward.
You’d literally have to be downing an entire bottle of low potency pills each day. Which is not only totally impractical, but downright expensive!
Hydrogen peroxide will whiten teeth, but it takes a long (think months to years) time.
Hydrogen peroxide is a powerful oxidant. Many people spend a lot of money on anti-oxidants to reduce cellular damage, why risk putting an oxidant on the soft delicate tissues of your mouth.
Yes, dental whitening products do contain hydrogen peroxide but it is packaged in such a way to contact teeth only, quickly and effectively. Why take a risk when we have great, inexpensive alternatives?
Hydrogen peroxide is used widely in professionally and self-administered products. Hydrogen peroxide is a highly reactive substance which can damage oral soft tissues and hard tissues when present in high concentrations and with exposures of prolonged duration. This report provides an overview of health issues relating to the use of hydrogen peroxide, with an emphasis on safety with prolonged exposure to low concentrations of peroxide products. There is good evidence for the safety of hydrogen peroxide when used at low concentrations on a daily basis over extended periods of time, in self-administered oral health care products such as dentifrices and mouthrinses. These low concentrations neither damage oral hard or soft tissues, nor do they pose a significant risk of adverse long-term effects. Caution should be exercised with the increasingly higher concentration peroxide products used for 'walking' or 'power' bleaching due to the possibility of chemical irritation of oral soft tissues with injudicious use. The volumes of material and application times should be controlled carefully. Thorough education of patients is particularly important with self-applied gels because of the lack of professional supervision with such products. Such education is part of the duty of care of the dentist who supplies bleaching gels for at-home use.
Phenanthroline, a strong iron chelator, prevents both the formation of DNA single-strand breaks and the killing of mouse cells produced by H2O2. These results, taken together with our previous findings, indicate that the DNA damage is produced by hydroxyl radicals formed when H2O2 reacts with chromatin-bound Fe2+ and that this damage is responsible for the killing effect.
Studies were conducted to evaluate the cell damage caused by exposing human colon carcinoma cells, Caco-2, to hydrogen peroxide at concentrations varying from 0 to 250 microM for 30 min. Evaluation of cell viability, as measured by trypan blue dye exclusion test, showed that the loss of viability was < 5% at concentrations up to 250 microM hydrogen peroxide. Cell membrane damage and DNA damage as measured by the leakage of lactate dehydrogenase and the comet assay, respectively, were significantly high at concentrations >100 microM hydrogen peroxide compared to those of the control. Antioxidant mechanisms in Caco-2 cells were evaluated by measuring catalase, superoxide dismutase, and glutathione peroxidase activities. Catalase activities remained constant in cells treated with 50-250 microM hydrogen peroxide. Superoxide dismutase activity decreased, whereas glutathione peroxidase activity increased in cells treated with H(2)O(2) concentrations of >50 microM. This study showed that with increasing hydrogen peroxide concentration, cell membrane leakage and DNA damage increased, whereas the three antioxidant enzymes responded differently, as shown by mathematical models.
