The mineral magnesium is crucial for the body to function properly because magnesium is involved in more than 600 of the body's enzymatic reactions.*

According to World Health Organization statistics, as many as 75 percent of U.S. adults do not meet the U.S. Food and Drug Administration's Recommended Daily Intake of 420 mg of magnesium. Magnesium deficiency can manifest in many ways, such as inefficient blood sugar metabolism, muscle cramps or soreness, eyelid twitching, fatigue, and poor sleep.*

Why is magnesium important?

• Magnesium is essential for the health of the heart and blood vessels, brain, bones, muscles, and lungs, and to support healthy blood sugar*
• Promotes bronchial relaxation*
• It’s an essential mineral for electrical activity of the heart, which supports healthy heart rate and rhythm*
• Helps relax smooth and skeletal muscle*
• Promotes the dilation of blood vessels (vasodilation), which supports normal blood pressure and enhances blood flow*
• Supports insulin sensitivity for healthy blood sugar*
• Is a cofactor for enzymes involved in cellular energy production*

Benefits of Thorne’s Magnesium Bisglycinate:

• Magnesium Bisglycinate is a great-tasting powder that can be mixed with water, juice, or with another powdered supplement.
• The compound magnesium bisglycinate is also called magnesium glycinate; however, because it has two glycine molecules attached, it is more accurately called "bisglycinate" (bis = two). The bisglycinate form has superior absorption because of increased solubility.*
• Decreased laxative effect compared to other magnesium formulations because the bisglycinate form is a true chelate that completely envelopes the magnesium.*
• Glycine is a neurotransmitter that promotes relaxation and stress reduction in the body – making Magnesium Bisglycinate a good choice for pre-bedtime supplementation to support restful sleep.*

Because athletes need to know their supplements are trustworthy, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations.

L-theanine is a unique amino acid that is found almost exclusively in the tea plant (Camellia sinensis) and which has been used safely in Japan for decades. L-theanine has been shown to positively modify brain waves and the key neurotransmitters involved in mood, focus, and memory.* L-theanine enhances the production of the neurotransmitters dopamine and serotonin, and also appears to play a role in the formation of GABA – a neurotransmitter that acts like a "brake" during times of runaway stress.* L-theanine also enhances brain alpha-wave activity, a marker of relaxation.* This effect has been observed to be most pronounced in individuals subjectively feeling the highest levels of stress.*

A Japanese study of university students found that 200 mg of L-theanine led to increased brain alpha-waves and a subjective sense of relaxation.* In the same study, L-theanine administration also caused a dose-dependent relaxed, yet alert, state of mind without sedation, beginning approximately 40 minutes after ingestion.*

L-theanine can enhance the production of the neurotransmitters dopamine and serotonin, and it appears to play a role in the formation of GABA – a neurotransmitter that acts like a "brake" during times of runaway stress.* L-theanine helps establish balance in the neurotransmitter system, resulting in improvements in the mental/emotional and physical disturbances resulting from being overly stressed.*

Two thyroid hormones – thyroxine (T4) and triiodothyronine (T3) – regulate the body's metabolism of proteins, fats, and carbohydrates, directing how the body uses these compounds to produce energy.* Thyroxine supports cardiac output, heart rate, respiratory rate, and basal metabolic rate.* The thyroid gland cannot produce these two hormones without the presence of the amino acid L-tyrosine and the mineral iodine.* Thus, a deficiency of either the amino acid or the mineral or both can contribute to low thyroid hormone levels.* Thorne's Iodine & Tyrosine offers essential mineral and amino acid support for the thyroid gland.* Studies have found L-tyrosine can be beneficial for treating fatigue, a common symptom of low thyroid or adrenal hormone levels.*

Tyrosine is also an important cofactor for adrenal neurotransmitter synthesis, because it is converted in the adrenal glands into dopamine, norepinephrine, and epinephrine.*

Individuals should be aware that some foods can cause a relative iodine deficiency by binding to iodine, which can make the bound iodine inaccessible for thyroid hormone production. These foods include broccoli, cauliflower, cabbage, Brussels sprouts, kale, soy, peanuts, pine nuts, turnips, and rutabaga, although cooking these foods tends to make them less apt to do this.
