What is F&Q?

F&Q stands for two outstanding ‘essential’ and ‘conditional’ amino acids which have proved with 1000s of clinical studies conducted by world renown neuro-scientists for over 60+ years to rebuild your thinking neurotransmitters and feed the master controller of your entire Endocrine System.

F = Phenylalanine

Pronounced: “D-L-FEN-L-AL-UH-NEEN” and includes these functions:

  • One of the eight essential amino acids crucial to the life of your brain and body which you must get from your diet and only lasts in your brain for about eight hours.
  • Exists in two forms; a D and an L form. D-phenylalanine is the enantiomer (mirror image) of l-phenylalanine and is one of the few “d” form aminos that has pharmacologically activity. D-phenylalanine works to inhibit the enzymes that break down the “opioids” in the brain. Opioids are like endorphins and produce a sense of well-being and calm. If the enzymes that break them down are not as active due to the action of d-phenylalanine, then the opioids activity increases and the person has a greater sense of internal calm. L-phenylalanine is converted into another amino acid, l-tyrosine. L-tyrosine is converted into l-dopa before being further converted into the neurotransmitters dopamine, norepinephrine, and epinephrine. D/L phenylalanine is a mixture of 50% l-phenylalanine and 50% d-phenylalanine.
  • Increases the endorphin and enkephalin levels in the blood. Endorphins are the natural morphine-like pain killing substances that are produced by the brain in response to pain.
  • Inhibits (slows down) the enzymes that break down the endorphins, thereby allowing them to remain longer and in greater supply than would normally be the case.
  • Precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline).
  • Too little F may cause anhedonia (an inability to experience pleasure), confusion, emotional agitation, depression, decreased alertness and memory, inability to feel remorse for or recognize consequences of behavior, and the lack of sympathy or connection.

Q = Glutamine

Pronounced: “L-GLOO-TUH-MEEN” and includes these functions:

  • Considered a “conditionally essential amino acid” because although it can be manufactured in the body, under extreme physical or emotional stress the demand for glutamine exceeds the body’s ability to synthesize it.
  • Major precursor for the neurotransmitter, GABA, or gamma amino butyric acid, and is especially important when the body is subjected to stressful situations. It has been stated that when there is no GABA, there is no calm and no sleep because the brain will not “turn off.”
  • Unlike glutamic acid, glutamine crosses the blood-brain barrier easily, readily reaching the central nervous system (CNS) for use.
  • Glutamic acid, having been converted to that form in the brain from glutamine, is involved in two key roles. Along with glucose, it is the fuel for the brain cells.
  • Potent energy source and is vital for high energy activities, such as exercise and projects requiring concentrated thinking and memory. Therefore, it is essential for supplying both the body and brain with energy.
  • Important for removing excess ammonia (a common waste product in the body). It has been shown to enhance the immune system. Also, people who are gluten sensitive can use glutamine without the problems often associated with sensitivity to monosodium glutamate.
  • All-natural anti-anxiety supplement, which allows the mind to relax without causing the side effects often associated with tranquilizers. It “tones down” unwanted “mind chatter,” which sharpens a person’s ability to focus and concentrate with more clarity or simply relax.

As shown, F & Q (“phenylalanine” and “glutamine”) amino acids are primary for nourishing and maintaining your neurotransmitters and hormones.

A healthy and balanced diet is crucial for hormonal health and overall endocrine system balance. Make sure to reduce hcf (high cholesterol foods) and eat wholesome organic foods with plenty of fruits and vegetables. With such a diet sustained by the F Q amino acids your overall health will be improved, including the regulation of hormone production.

Your neurotransmitters must have a ready daily supply of these two amino acids in order to create happy, calm and focused thoughts every day.

Starving Hormones?

What controls all your hormones (Endocrine System) and what “one” amino acid does it need to keep everything balanced properly?

The answer is found in a little place in your brain called the hypothalamus, a gland about the size of the tip of your thumb. It is often referred to as the “master controller” in charge of regulating your entire hormonal (endocrine) system, orchestrating what all the other glands of the endocrine system do. In addition to this aspect of metabolism, the hypothalamus also regulates body temperature and the hunger response. More blood gushes through the hypothalamus than any other part of the brain.

Notice from the accompanying video below everything your hypothalamus controls and yet there is “only one” amino acid that nourishes it: “F (Phenylalanine)”.


Balancing Hormones

  • Hormones are powerful chemical messengers. They float through the blood stream, telling various cells they come in contact with what to do.
  • Hormones tell your bones how much calcium to store or to release, influencing your height, muscle growth, and even how strong your bones are.
  • Hormones tell your body at what rate to metabolize. This decides whether you are underweight, overweight, or just right.
  • Hormones tell your body when and where to store fat, thus deciding your shape, as well as, blood sugar, estrogen, progesterone and testosterone levels.
  • Hormones tell your body how little or how much of a sex drive you’re going to have. This in turn, influences marital bliss, or a lack thereof.
  • Hormones tell your body how to react to emotional stress and anxiety.
  • Hormones directly affect your mood, largely influencing your happiness or causing depression.
  • Hormones tell your mind when you will sleep and for how long. Sleep problems are directly related to hormones.
  • Hormones, when imbalanced (sending the wrong chemical message), are the cause of high blood pressure, fatigue, hair loss or thinning, migraine headaches, and problems with PMS and/or menopause.
  • Hormones affect your overall health and well-being: how athletic you are, how happy you are when you look in the mirror, how great or poor of a sex life you have, how you deal with stress, your mood (happy or sad), and how well or how poorly you sleep.
