DESCRIPTION Thyronyl is a complex preparation that contains all the important nutrients for a properly functioning thyroid gl&. The thyroid plays a central role in metabolism. The thyroid operates numerous processes in the body, from energy management to the operation of the cardiovascular & nervous systems. A thyroid that functions properly requires a number of important nutrients. These have been combined in the product Thyronyl. Iodine is an important regulator for the thyroid. It is a key component of the thyroid hormones triiodothyroxine (T3) & L-thyroxine (T4). According to a study presented in 2011 the average urinary iodine level of the British population is 80 mcg per litre, making the average British person iodine-deficient by World Health Organisation standards. Thyronyl contains iodine from a natural source, namely kelp. Kelp is a seaweed & is rich in iodine. Kelp also contains other minerals & trace elements that occur naturally in seawater. Selenium is another important component. Selenium is an essential element of the enzymes responsible for the conversion of T4 into the active thyroid hormone T3. Iodine & selenium work together & cannot function without each other in thyroid metabolism. The amino acid L-tyrosine is the most important building block for T3 & T4. Other important synergists in Thyronyl are zinc & niacin (vitamin B3). These substances support thyroid metabolism in various ways. Most important features of Thyronyl: Contains selenium & iodine: these minerals work together in thyroid metabolism Contains iodine from a natural source, namely seaweed (kelp) Important synergists: L-tyrosine, zinc, niacin USE Take 3 times a day 1 capsule, during or immediately after a meal.
