What are Amino Acids?
As the building blocks of protein, Amino Acids are vital to health. Next to water, amino acids in the form of proteins make up the greatest portion of our body weight. They comprise tendons, muscles and ligaments; organs and glands; hair and nails; important bodily fluids, and are a necessary part of every cell in the body.

There are over 20 amino acids, separated into two categories essential and non-essential. Essential amino acids are those that cannot be manufactured by your body, hence, it is essential that you obtain them from your diet. Non-essential amino acids can be manufactured by your body, however, your body must have the right combination of essential amino acids and supporting nutrients to optimize healthy protein maintenance, so supplementation may be desirable.

L-Tyrosine
Vital for overall metabolic processes, this non-essential amino acid plays a role in the production of the neurotransmitters dopamine and norepinephrine, as well as serving as a precurosor for adrenaline. Because of its importance in the prodction of neurotransmitters, Tyrosine helps to maintain a healhty mood. In addition, this amino acid plays an important role in the healthy functioning of the adrenal, thryoid and pituitary glands.

Supplementing with Tyrosine may be useful for stress reduction, chronic fatigue, anxiety, depression, low sex drive, inactive thyroid and weight management.

It should be taken at bedtime or with high carbohydrate meals so that it doesn't have to complete for absorption with other amino acids.

Low Thyroid Function
Low thyroid has become a very common health concern with very real symptoms that affect both a person's physical as well as emotional health. Many people may have it yet do not know; in fact, it can go undiagnosed for many years because the "normal" level of thyroid hormones can vary from person to person.

Many natural health care practitioners prefer the reliability of the basal temperature test (done in the morning) because it can identify people with borderline low thyroid. Low thyroid causes the body to be slightly colder than a healthy person. While only the difference of at the most two degrees, it can have broad ranging effects on many different functions of the body resulting in many different symptoms.

Firstly, in a hypothyroid state the body's metabolic rate is decreased. This is why most people with low thyroid experience weight gain. Secondly, lower levels of thyroid hormones can affect the production of neurotransmitters and how well they are used in the brain and other parts of the body - this can lead to common low thyroid symptoms like depression, anxiety, poor memory, and insomnia. In this respect, it can also affect digestion because enzymes, just like neurotransmitters, do not function as they should when the body temperature is lowered - this can result in poor digestion of food, which can be manifested as gas, upset stomach, heartburn or constipation. The hormone insulin (responsible for regulating the level of sugar in the blood) is equally affected lower temperatures in the body and explains why many with low thyroid often experience fluctuations in blood sugar like yo-yoing effect of hypoglycemia. Some of these may need to be treated along with the low thyroid.

Low thyroid can also: lower immune system function, cause dry skin, lower blood pressure and raise cholesterol, promote water retention, cause menstrual irregularities in women, cause muscle aches and pain, and create allergies. Hypothyroid sufferers also report fatigue, an increased need for sleep, decreased initiative, lack of concentration, poor memory, bowel changes, muscle and joint aches, and asthma. Because of the broad range of effects that low thyroid has on over all health, it is important that it be treated. Left untreated long term hypothyroidism can cause serious concerns that can affect your quality of life.

There can be many causes of low thyroid, including: hormonal changes (especially during pregnancy), lack of iodine in the diet, an abnormal immune system reaction (as in Hashimoto's), heredity, stress, treatment for an overactive thyroid, chemical pollutants and heavy metal poisoning. It is important to discover the exact cause of low thyroid so that the root cause can be treated.

Nutritional support for an under active thyroid gland can include among many other supplements, thyroid glandular extract. Thyroid glandular boosts the activity of your own thyroid gland, optimizing its production T3 and T4. Ensuring that your are getting enough of important nutrients like iodine and tyrosine is crucial for natural thyroid support.
