• Mental Energy and Stamina*

Stay Sharp and Focused
Mental Advantage delivers nutrients that support healthy brain activity for accuracy and recall, mental energy and stamina, and healthy memory.*^

Clinically Studied HRG80Red Ginseng
HRG80 delivers 7 times the levels of noble ginsenosides—compounds associated with the plant’s most beneficial effects—compared to standard red ginseng extracts. Noble ginsenosides are incredibly well absorbed, too—about 17 times better than classic ginsenosides, found in conventional supplements.

These key differences make for real-world results: clinical research shows HRG80 significantly supports accuracy, recall, and attention compared to placebo.*

Bioactive B Vitamins
Common supplemental B vitamins can be difficult for some people to convert into active B vitamins their mind and body need. Mental Advantage contains bioactive B vitamins, which require no conversion by the liver. Bioactive B vitamins deliver optimum benefits for cognitive support, brain and nerve function, and daily energy.*

Absorption: The Crucial Difference with GammaSorb®
GammaSorb is a unique delivery system shown to increase the absorption of certain hard to absorb (fat soluble) nutrients by as much as 8 times.

^Based on a randomized, double-blind, placebo-controlled study of the ingredient HRG80™ Red Ginseng.
†Compared to classic ginsenosides in an in-vitro scientific (Caco-2) study.

Stress and Thyroid Health

Too much stress isn't good for our health!

Because the same parts of your brain control both your adrenal and thyroid hormones, there is a connection between stress and low thyroid problems. The adrenal hormone cortisol and thyroid hormones work together, forming your stress response.

You may be suffering from a combination of adrenal stress and thyroid imbalance for months or years without realizing it, because thyroid imbalances may not immediately produce obvious symptoms.

Thyroid Symptoms Caused By Stress

Fatigue •  Sluggishness •  Cold Intolerance •  Weight Gain •  Memory Loss •  Poor Concentration •  Depression •  Infertility •  Hair Loss

Marietta Health Foods carries Terry Naturally products that are designed to address thyroid stress.

The Nutrients Your Thyroid Needs!

Iodine in three forms, including potassium iodide, sodium iodide, and molecular iodine for thyroid hormone synthesis, which in turn supports a healthy metabolism, lustrous hair, and hormone balance.*

L-Tyrosine, an amino acid required to create thyroid hormones, supports mental well-being and daily energy.*

Thyroid Care supports:

  • Daily Energy
  • Healthy Metabolism
  • Lustrous Hair
  • Hormone Balance
  • Healthy Weight Management† († In conjunction with a healthy diet and exercise regimen)
  • Immune Health*


Why should I care about iodine?

Iodine is one of the most important minerals for healthy cellular and metabolic function.* There was a time when iodine figured big into the American diet, especially after the connection between goiters and iodine deficiency was made clear, leading to the formulation of iodized table salt. However, with more recent concerns about sodium intake, there may be even less iodine in the American diet than there was just 50 years ago. In fact, it has been estimated that the entire American population is deficient in iodine, possibly due to changes in diet and a reduction in the use of table salt. Additionally, certain toxic minerals “compete” with iodine. As we are exposed to greater levels of chlorine, bromine (bromide) and fluoride, the body requires more iodine for ongoing detoxification.

What exactly is “tyrosine” or “L-tyrosine”?

Tyrosine is an amino acid. It is generally considered a “conditionally essential” amino acid because the body can typically synthesize adequate amounts of tyrosine from phenylalanine. However, in addition to thyroid hormone support, supplemental tyrosine has been found to be beneficial for mood, stress relief, and mental function.* Food sources include cheese, eggs, almonds, and avocados. Tyrosine, (also called “L-tyrosine”) is the precursor for the formation of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), as well as epinephrine, norepinephrine and dopamine.*
