            What Is Dopamine—And Why It Matters For Your Mental Health

            Dopamine, the “motivation molecule,” drives focus, productivity, and the sense of reward that keeps you moving toward your goals. Its production depends on key nutrients like amino acids, vitamins, and methyl donors. Dopamine Brain Food™ provides these essential building blocks to support healthy dopamine levels

            FAQS

            help

            What is MagTech® and what is it used for?

            MagTech® is an advanced 3-in-1 chelated magnesium complex designed to support relaxation, sleep quality, and brain health. It features three highly bioavailable forms of magnesium (including clinically-tested Magtein™ magnesium-L-threonate) that deliver magnesium to the brain and body, promoting deep REM sleep, calmness, and long-term cognitive function—without morning grogginess.

            help

            What makes MagTech® different from other magnesium supplements?

            Most magnesium supplements use a single, low-bioavailability form (e.g., magnesium oxide, which has only 4% absorption). MagTech® combines three premium chelated magnesium forms (Magtein™ magnesium-L-threonate, magnesium glycinate, magnesium taurate) in one formula. Magtein™ is a patented, MIT-developed magnesium that crosses the blood-brain barrier—in vitro research shows it supplies more magnesium to the brain than other magnesium forms. It’s also the best-selling cognitive health supplement in the Natural Channel (SPINS, 52 weeks ending Oct 6, 2024).

            help

            What is the difference between elemental and actual magnesium?

            Supplement labels list elemental magnesium (the active, absorbable mineral your body uses), not the total weight of the magnesium compound. Bioavailability (absorption) is far more important than raw weight: MagTech® uses the three most absorbable magnesium forms, while cheap forms like magnesium oxide have high elemental magnesium content but almost no absorption. MagTech® delivers 200mg of elemental magnesium per serving (48% Daily Value) from its three complex forms.

            What is Dopamine Brain Food™ and what is it used for?

            Dopamine Brain Food™ is a science-backed neurotransmitter support supplement designed to fuel your brain’s natural dopamine production—the “motivation molecule” that regulates focus, attention, drive, and the brain’s reward system. It’s formulated for morning use to boost mental drive, concentration, and alertness (no jitters or crashes) and help you stay focused on daily goals and tasks.

            help

            What is dopamine, and why is it important?

            Dopamine is a key neurotransmitter that controls feelings of motivation, focus, attention, mood, and reward-seeking behavior. It powers your ability to tackle goals, stay determined, and feel a sense of accomplishment. Low dopamine levels can lead to brain fog, low motivation, and poor concentration—Dopamine Brain Food™ provides all the raw materials your brain needs to synthesize dopamine naturally.

            What ingredients are in Dopamine Brain Food™, and what do they do?

            Dopamine Brain Food™ contains 7 research-backed ingredients that support every step of dopamine synthesis:

            • L-Tyrosine & L-Phenylalanine: Amino acid precursors that your brain converts into L-DOPA (the direct building block of dopamine).
            • Vitamin C, B6 (P5P): Cofactor vitamins that catalyze dopamine synthesis and boost alertness (converts dopamine to norepinephrine).
            • Folate (Quatrefolic®) & B12 (Methylcobalamin): Bioactive B-vitamins that support methylation and neurotransmitter production.
            • TMG (Trimethylglycine): A methyl donor that fuels dopamine synthesis and attention-based brain activity.

            It delivers 500mg Vitamin C (556% DV), 5mg B6 (294% DV), 1000mcg folate (250% DV), and 4000mcg B12 (166,667% DV) per 3-capsule serving.
