DL Phenylalanine (DLPA) & L Glutamine Amino Acids, Vitamins and Minerals

HCF Happy, Calm & Focused is an original, pure and effective dietary supplement, considered one of the most exciting discoveries in brain supplementation in decades!*

The advantage HCF has over other brain supplements is that typical brain supplements rely on high dose ’50 ingredients-in-1' glorified multi-vitamins or just herbs to artificially give your brain a lift, while HCF supports naturally feeds your brain’s own neurotransmitters with what it is ‘suppose to have’ – F&Q amino acids.

HCF is fueled by F&Q (F or DL-Phenylalanine DLPA, Q or L-Glutamine). These two powerful key amino acids are found in whole-food proteins like fish, milk, cheese and turkey. F&Q works by naturally supporting the increase of “feel good” neurotransmitter levels responsible for helping you feel happy, calm and focused every single day.

What is DL Phenylalanine DLPA?

DL Phenylalanine (F) is an amino acid of tremendous nutritional importance and a known nutritional precursor to the neurotransmitters tyrosine, dopamine, norepinephrine (noradrenaline), epinephrine (adrenaline) and involved in the release of PEA, phenylethylamine which can sensitize endorphin receptors to endorphins. These neurotransmitters strongly support warm feelings of love, pleasure, happiness, alertness, energy, motivation, memory, attention, internal calmness, and sleep to name just a few.*

What is L Glutamine?

L-Glutamine (Q) is an amino acid and a major precursor for the neurotransmitter GABA, or gamma amino butyric acid. This crucial amino acid helps the mind relax and "tone down" unwanted "mind chatter" which can sharpen a person's ability to focus and concentrate with more clarity.*

These absolute, and precise levels of synergistic vitamins, minerals and other nutrients support DL Phenylalanine (DLPA) amino acid and & L Glutamine amino acid pass through your BBB (Blood Brain Barrier) and finally nutritionally feed your brain.*

Amino acid F is normally found in foods like fish, algae, wheat germ, green leafy vegetables, etc. It is the precursor to the neurotransmitters Dopamine, Epinephrine, and Norepinephrine. Amino-Acid Q, or L-Glutamine, is manufactured in the body and found in foods like fish, beef, chicken, cabbage, beans, and spinach. Amino acid Q is a precursor to the neurotransmitter GABA, or gamma-aminobutyric acid, and plays a role in regulating neuron excitability. Dopamine, Epinephrine, GABA and Norepinephrine are neurotransmitters associated with feelings of well-being and focus.
