Vit C in it's sodium ascorbate form is not as effective in combination with Iodine
- preferably l-ascorbic acid for use with your iodine.
sodium ascorbate is the 'buffered', 'neutral' form, the ascorbic acid bound with sodium (salt) so that large doses don't induce diorrea. It's a good supplement for megadosing therapies that some folk use for anticancer therapy and against candida
(both of which Iodine
therapy with co-nutrients also aims to address.)
One of the most overlooked and most important co-nutrient when taking iodine:
selenium (yeast free) in the form of methyl-selenocysteine and selenomethionine. If you're hypothyroid (or have hashimoto's) or depressed/sluggish and have had exposure to methylmercury (if you've had 'silver'-amalgam fillings, lotsa tuna, or other food/industrial pollutant sources), then it's highly reccommended.
Dr's best selenomethionine 200mg is very good, and I also buy Vitamin Research Products (VRP) SelenoCysteine. The selenocycteine is expensive, but it doesn't contain fillers like rice flour, maltrodextrin (wheat sugar) etcs, which can reduce how well you can absorb the mineral.
Some folk (the report I read in the IodineVWT team archives was on a fellow around 50 years old) react poorly to selenium- adding TMG (tri methyl glycine) tablets between 1-3 grams a day solves these issues.
Selenum's a balancer of the effects of iodine, and it is an important part of the glutathione cycle in the body (especially the liver). Iodine
is used clinically to halt cases of hyperthyroidisim (hyperactive thyroid).
"Selenium also plays a very important role in the production of Glutathione, the body's most powerful antioxidant. During the production of thyroid hormones, hydrogen peroxide is produced, high Iodine in the absence of selenium destroys the thyroid gland (often felt as a sore throat feeling), the peroxides are neutralized through the production of glutathione from selenium. In turn an excess of selenium increases demand for iodine, and deficiency will result when a diet is high in selenium and low in iodine." ( https://en.wikipedia.org/wiki/Iodine_in_biology
And theeeeere's why you need to have selenium in your med cabinet. ;)
On the flipside, low fat-soluable-vitamin status is something vital to test for. Low vit D3 status makes it much, much harder to absorb minerals well- and that's nearly a given if you're not a garden-beach-biking sort. Always worth getting tested with the doctor.
Bless and good hunting!
