Thyroxine and triiodothyronine are tyrosine-based hormones produced by the thyroid gland. An important component in the synthesis of thyroid hormones is iodine. The thyronines act on nearly every cell in the body. They act to increase the basal metabolic rate, affect protein synthesis, help regulate long bone growth (synergy with growth hormone), neuronal maturation and increase the body’s sensitivity to catecholamines (such as adrenaline) by permissiveness.

The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds. They also stimulate vitamin metabolism. Numerous physiological and pathological stimuli influence thyroid hormone synthesis.

Effects of thyroxine:

• Increases cardiac output
• Increases heart rate
• Increases ventilation rate
• Increases basal metabolic rate
• Potentiates the effects of catecholamines (i.e increases sympathetic activity)
• Potentiates brain development
• Thickens endometrium in females

Thyroid hormones are usually not dangers for pregnant women or nursing mothers, but should be given a doctor’s supervision. One exception is that thyroid hormones may aggravate heart conditions, especially in older patients; therefore, doctors may start these patients on a lower dose & work up to avoid risk of heartattack.

Amino acids are the building blocks of proteins. Amino acids are essential to the human body. They build the cells, repair tissues, are responsible for the production of enzymes, and play a key role in mental health. All amino acids are essential for proper protein synthesis. A shortage of even one amino acid can cause protein synthesis to be greatly reduced and it can stop altogether if left untreated.

Amino Acids Supplement come in the form of pills, capsules, or powders containing a particular concoction of amino acids. Most amino acid supplements are sold as anabolic agents to help in body-building; arginine and ornithine are two constituents frequently promoted as ‘natural steroids’ (a distinctly misleading name since they are chemically very different from steroids).

Since amino acids are the building blocks of protein, the main component of muscle, many people believe that just by taking extra amino acids they can develop larger muscles. However, a muscle grows only in response to extra physical demands placed on it.

Bodybuilders can especially benefit from supplementing amino acids because they aid in repair, growth, and development of muscle tissue.

Overconsumption causes health risks. Unbalanced amino acid mixtures or single amino acids may be toxic. If amino-acid supplements are used as the basis of a high-protein, low fat diet they can be downright dangerous because they can cause abnormal heart rhythms.
One and one-half grams of powder three times a day should be sufficient to provide the body with an adequate supply of available amino acids to assist in digesting food and bulking up. There are no side effects with proper supplementation.
