Your brain is the most energy-hungry organ in your body — consuming roughly 20 percent of your total oxygen supply despite being only about 2 percent of your body weight. Every thought, every memory, and every decision depends on reliable blood flow delivering oxygen and nutrients to billions of neurons.
Memodyne was formulated around a simple premise: before chasing neurotransmitters with stimulants, first make sure the delivery system actually works. This page walks you through all six primary nutrients inside every Memodyne capsule — what they are, what role they play, and why they were included.
The Complete Breakdown — All 6 Ingredients Explained
INGREDIENT 01
L-Arginine — 200 mg
L-Arginine is a semi-essential amino acid that serves as the primary raw material your body uses to manufacture nitric oxide. This is not a minor detail — nitric oxide is the signaling molecule that tells your blood vessels to relax and dilate, allowing blood to move through with less resistance.
When your blood vessels open wider, oxygen-rich blood reaches your brain more efficiently. That improved delivery means better fuel for the neural processes behind focus, recall, and clear thinking. L-Arginine has been included in cardiovascular and cognitive wellness formulations for decades precisely because of this fundamental role.
In the Memodyne formula, L-Arginine is the starting point of the entire mechanism. It kicks off nitric oxide production, and the other ingredients are designed to sustain, recycle, and protect that process throughout the day.
The Nitric Oxide Connection
Nitric oxide (NO) is produced when the enzyme nitric oxide synthase converts L-Arginine into NO and L-Citrulline. The NO relaxes smooth muscle in blood vessel walls, widening them — a process called vasodilation. This is the core mechanism behind Memodyne's approach to cerebral blood flow support.
INGREDIENT 02
L-Arginine AKG 2:1 — 200 mg
If standard L-Arginine is the ignition key, L-Arginine AKG is the cruise control. This compound binds arginine with alpha-ketoglutarate (AKG) in a 2-to-1 ratio, which changes the way your body absorbs and processes the amino acid.
The practical result is a slower, more sustained release of arginine into your bloodstream. Instead of a rapid spike followed by a quick decline, your nitric oxide levels stay elevated over a longer window. This matters because your brain does not just need fuel at 8 AM — it needs steady delivery from the moment you wake up until you wind down at night.
Alpha-ketoglutarate itself is also a key player in the Krebs cycle — the metabolic pathway your cells use to generate energy. So this ingredient pulls double duty: sustained nitric oxide support on one hand, and cellular energy metabolism support on the other.
INGREDIENT 03
L-Citrulline HCl — 100 mg
Here is where the Memodyne formula gets clever. When your body produces nitric oxide from L-Arginine, the byproduct left behind is L-Citrulline. Most supplements stop there. But Memodyne includes L-Citrulline HCl specifically because your kidneys can convert citrulline back into arginine — creating a self-sustaining recycling loop.
This means that even after the initial L-Arginine dose has been used up, your body keeps generating fresh arginine from the citrulline byproduct. Nitric oxide production continues hour after hour without requiring additional capsules. It is an elegant biological design that most cognitive supplements do not take advantage of.
The HCl form (hydrochloride) simply improves absorption, helping the citrulline reach your bloodstream faster and in a more bioavailable state.

L-Citrulline Malate — 100 mg
L-Citrulline Malate pairs citrulline with malic acid — a naturally occurring compound found in apples and other fruits. This pairing serves a dual purpose that goes beyond what standard citrulline delivers.
First, like L-Citrulline HCl, it continues the arginine recycling loop that keeps nitric oxide production running. Second, the malic acid component directly feeds into the Krebs cycle — the central metabolic engine your cells rely on for energy production.
But there is a third benefit that is especially relevant for cognitive function: L-Citrulline Malate helps your body clear ammonia and other metabolic waste products from the bloodstream. Ammonia buildup contributes to that heavy, sluggish feeling of mental fatigue. By accelerating waste clearance, this ingredient helps keep your thinking sharp during the most demanding parts of the day.
INGREDIENT 05
Beta-Alanine — 40 mg
Beta-Alanine is a non-essential amino acid best known in the fitness world for buffering acid buildup in muscles. But its real value in the Memodyne formula is what happens inside the brain.
When you consume Beta-Alanine, your body combines it with histidine to produce carnosine. Carnosine is a dipeptide with potent antioxidant properties — and your brain contains significant concentrations of it. As an antioxidant, carnosine helps neutralize free radicals and reactive oxygen species that damage neurons over time.
This oxidative damage is not hypothetical. It accumulates daily — from mental strain, environmental exposure, poor sleep, and the simple passage of time. Beta-Alanine gives your brain an additional layer of biochemical defense against this ongoing wear.
Why Neuroprotection Matters
Cognitive decline does not happen overnight. It is the gradual result of cumulative oxidative stress, reduced blood flow, and declining cellular energy — processes that start decades before symptoms become obvious. Memodyne's inclusion of Beta-Alanine addresses the protection side of brain health, while the arginine-citrulline system handles the delivery side.
INGREDIENT 06
Niacin (Vitamin B3) — 7.5 mg NE (47% DV)
Niacin is not a trendy supplement ingredient — it is a well-established essential vitamin that your body cannot function without. Its inclusion in Memodyne is based on one critical role: Niacin is the precursor to NAD+ (nicotinamide adenine dinucleotide), arguably the most important coenzyme in your entire metabolism.
NAD+ is required for energy production in every cell of your body, including the billions of neurons in your brain. It powers the electron transport chain — the final step of cellular respiration that generates the ATP your cells use as fuel. Without adequate NAD+, your neurons literally run out of energy.
Beyond energy, NAD+ is involved in DNA repair, gene expression regulation, and maintaining healthy neurotransmitter signaling. Brain cells are particularly vulnerable to NAD+ depletion because they operate at such high metabolic rates. By including Niacin at 47 percent of the daily value, Memodyne ensures a meaningful contribution to your body's NAD+ production without exceeding safe intake levels.
How These 6 Ingredients Work as a System
Most brain supplements stack a handful of unrelated nutrients and hope they add up to something useful. Memodyne takes a different approach — every ingredient was selected to play a specific role in a connected biological system:
- Nitric Oxide Production: L-Arginine provides the raw material; L-Arginine AKG sustains it over hours
- Continuous Recycling: L-Citrulline HCl converts back to arginine, keeping the NO loop running
- Energy & Waste Clearance: L-Citrulline Malate fuels the Krebs cycle and clears ammonia buildup
- Antioxidant Defense: Beta-Alanine builds carnosine to protect neurons from oxidative damage
- Cellular Power: Niacin drives NAD+ production for sustained brain energy and neurotransmitter health
Together, these ingredients form what might be called a supply-and-protect strategy. The arginine-citrulline complex opens the delivery routes and keeps them flowing. Beta-Alanine guards the neurons that receive that delivery. And Niacin ensures those neurons have the internal energy to actually do their job.
This interconnected system is what separates Memodyne from single-ingredient memory pills or caffeine-based focus drinks. It does not artificially stimulate your brain — it supports the biological infrastructure your brain needs to perform at its natural best.
Other Ingredients in the Capsule
Beyond the six active nutrients, the Memodyne capsule shell and formulation include: Calcium (18 mg as calcium carbonate), Hypromellose (vegetable capsule shell), Vegetable Stearate (flow agent), and Silicon Dioxide (anti-caking agent). These are standard pharmaceutical-grade excipients used to ensure consistent dosing and capsule integrity.
