Test used to determine the Vitamin D content in the body

The best way to determine the content of vitamin D in the body is 25-hydroxy vitamin D blood test. This test determines the accurate reading of vitamin D in the body. The reference value which is used as standard values to  compare with the value obtained in the body are 20-50ng/ml below or above this may be considered to have severe deficiences or toxicity in the body.

Standards have been set by Food and Nutrition Board (FNB) i.e 400IU (International Units) per day standard that is safe. Different bodies have decided different limits as per their understanding.This values of 400IU to 600IU help to achieve the blood levels of 20ng/ml and 30ng/ml respectively.

Thyroid and weight gain

During thyroid disorder , patients are having an underactive thyroid activity and they tend to have a very low basal metabolic rate. This low metabolic rate  reduces the body rate to breakdown food and digest it which in turn leads to weight gain and difficulty losing extra weight.

The ratio varies among man and women while minority of women are not affected by weight gain . The difference in weight gain varies from their individual biochemistry, the quality of calories they consume and how they effectively use those calories.

To control weight gain one should consider and abide to strict diet and physical exercise to increase the metabolic rate and to burn calories such to avoid accumulation of calories and weight gain.

How long does levothyroxine stays in the body

According to the physical and chemical properties it can be predicted from the half  life of levothyroxine i.e estimated 7days half life which means that concentration of drug in the body decreases to half of the initial concentration which has been taken. For example, if you take an 100mcg of levothyroxine at day 1 it will reduce to half of its concentration at day 7 .

Therefor after 15days levothyroxine will be removed from the body system. The duration may vary depending upon the medical condition too, like if an person is having hyperthyroidism the half life is reduced to 3-4days whereas it is visa versa in case of hypothyroidism half life is increased to 9-10days.

Can we take levothyroxine and vitamin D side by side

In my opinion, each and every supplement should be separated by 4 hours with the thyroid medication to avoid decrease in absorption of levothyroxine systematically . If their is changes in absorption of levothyroxine in patients then dose adjustment is needed to maintain the same therapeutic effect required to provide the biological effect to avoid any side effects in the body system and lead the body functioning smoothly.
