Dementors drain âpeace, hope, and happiness out of the air around them,â according to Lupin (PA10). Even before a Dementor is seen, its presence is obvious; they are surrounded by an unnatural darkness and terrible icy cold (PA5). Dementors affect even Muggles, although the Muggles canât see the foul, black creatures. They were the guards at Azkaban and made that place horrible indeed.
The thyroid gland of a healthy adult concentrates 70-80% of a total body iodine content of 15-20 mg and utilizes about 80 Î¼g of iodine daily to synthesize thyroid hormones. In contrast, chronic iodine deficiency can result in a dramatic reduction of the iodine content in the thyroid well below 1 mg (1).
A serving of spirulina can contain from 16 micrograms, or about 10 percent of your daily need, up to over 15,000 micrograms, or over 1,000 percent of what you need each day. Too much iodine can cause a goiter and thyroid deficiencies, but an overdose is quite rare. The upper limit for iodine is 1,100 milligrams per day.
