When pollution is caused by nutrients and fertilizers, this is called nutrient pollution, and it leads to an overproduction of algae and other aquatic plants. This overabundance of plants and algae causes problems, because they cover the water surface and prevent sunlight from reaching the plants underwater.
Reverse T3 is actually an antithyroid -- T3 is the active thyroid that goes to the cells and stimulates energy and metabolism. Reverse T3 is a mirror image -- it actually goes to the receptors, sticks there, and nothing happens. So it blocks the thyroid effect. Reverse T3 is kind of a hibernation hormone, in times of stress and chronic illness, it lowers your metabolism.
FREE T3: T3 is the active thyroid hormone. Free in front of the T3 means you are measuring what is available and unbound. Those on an optimal amount of desiccated thyroid, with no lingering hypothyroid symptoms and in the presence of healthy adrenals, tend to have a free T3 towards the upper part of the range. Dosing solely by the TSH and the total T4, or using the outdated Thyroid Panel. 2  Prescribing anti-depressants in lieu of evaluating and treating the free T3. 3  Telling thyroid patients that desiccated natural thyroid is unreliable, inconsistent, dangerous or outdated.
