Beta-Alanine in Memodyne: A Workout Amino Acid at 40 mg
Memodyne lists 40 mg of beta-alanine per capsule, the last line on its panel. Sports studies gave 1.6-6.4 g a day, so one capsule is about one-fortieth of the lowest amount tested. Tingling starts near 800 mg in a single dose, twenty times more. Neither the label nor our sources explain what 40 mg is meant to do for memory (NIH ODS, Exercise supplements).

The last line on the panel
What kind of ingredient is beta-alanine, and where does Memodyne list it?
Your body makes beta-alanine on its own, and meat and fish supply more of this amino acid. Gyms know it as a common pre-workout powder ingredient.
In muscle, it pairs with another amino acid to form carnosine, a compound that helps buffer the acid built up during hard, short bursts of effort. That is why almost all research on it involves sprints, rowing, cycling or lifting (NIH ODS, Exercise supplements).
| Label name | Beta Alanine |
|---|---|
| Scientific name | Amino acid |
| What it is | Amino acid |
| Position in the list | 7 of 7 (every line prints its own amount) |
| Per capsule | 40 mg |
| Amount used in research | Sports research: 1.6-6.4 g a day for up to 8 weeks |
| Strength of evidence | No memory evidence |
| Traditional or marketed use | Workout amino acid known for skin tingle |
| Main caution | Tingle starts around 800 mg in one dose; 40 mg is well below it. |
Memodyne prints it as "Beta Alanine 40 mg" with no Daily Value, since none exists for this amino acid. It is the smallest of the seven amounts on the bottle.
Dose check
How much beta-alanine did sports research use?
Grams, not milligrams. Trials gave 1.6 to 6.4 g a day, often split into several smaller servings.
Results for exercise are mixed, in the words of the federal ODS fact sheet. Some trials saw a little more output in high-intensity efforts lasting one to a few minutes; others saw nothing (NIH ODS, Exercise supplements).
| Amount | What it is | Compared with 40 mg |
|---|---|---|
| 40 mg | One Memodyne capsule | Baseline |
| 800 mg | Single dose where tingling can begin | 20 times more |
| 1.6 g a day | Low end of sports trials | 40 times more |
| 6.4 g a day | High end of sports trials | 160 times more |
Matching even the low end would take 40 capsules in one day, more than a whole bottle. The label sets one.
Paresthesia
Is the beta-alanine tingle a concern at 40 mg?
No. The pins-and-needles feeling, called paresthesia, shows up with single doses of about 800 mg or more (NIH ODS, Exercise supplements). A Memodyne capsule holds one-twentieth of that.
At gram doses it tends to prickle across the cheeks and neck, the backs of both hands and the upper chest and back. It fades within 60 to 90 minutes and is not considered harmful. Some users also report itchy skin (NIH ODS, Exercise supplements).
Look elsewhere first. A pre-workout powder taken the same morning is the usual source, since those products often carry grams of beta-alanine. Sudden numbness or weakness on one side of the body is different: call 911 (CDC, Stroke signs).
How long it was tested
How long has beta-alanine been studied for safety?
Up to about 8 weeks. At 1.6 to 6.4 g a day, beta-alanine appears safe for that span, according to the ODS review of sports supplements (NIH ODS, Exercise supplements).
- Day 1
Large single doses can bring the short-lived tingle. Not a risk at 40 mg.
- Weeks 1-8
The window covered by the safety data, at gram doses far above Memodyne's.
- Beyond 8 weeks
Not well described in our source. Memodyne's 30-day bottle and 180-day pack both run in this zone if you keep going.
A very small amount does not make the unknown period risky by itself. It does mean nobody has measured long-term use of this exact capsule, for beta-alanine or any other line.
The open question
What is 40 mg of beta-alanine supposed to do in a cognitive formula?
No one has said. The label gives no reason, and the cited fact sheet discusses beta-alanine only for exercise.
Listed, not explained
The bottle names it on the Supplement Facts and stops there. No line on the wrap ties it to focus, clarity or energy, the three icons on the front.
Built for muscle work
The ODS sheet reviews it for short, intense exercise. It says nothing about memory or thinking (NIH ODS, Exercise supplements).
Far from any tested level
Even if a brain effect existed at sports doses, 40 mg is a small slice of what was studied.
Studies linking amino acids like this one to recall remain early, and many use animals. We have no source showing a benefit in people, so we make no claim. The sales page's wider idea is covered on how Memodyne is meant to work.

Does Memodyne's beta-alanine add up with a pre-workout?
It adds very little. A pre-workout scoop usually brings far more beta-alanine than a Memodyne capsule.
| Source | Typical label line | What to watch |
|---|---|---|
| Memodyne capsule | Beta Alanine 40 mg | Well under the tingle mark |
| Pre-workout powder | Often listed in grams, sometimes inside a blend | A blend may hide the exact amount |
| Standalone beta-alanine | Often near the gram range used in trials | Tingling likely from 800 mg per dose |
| Meat and fish | No label | Normal food intake, no concern |
If you already use a sports formula, Memodyne's 40 mg changes your total by a sliver. The bigger question with the capsule is its 400 mg of L-arginine, which matters for blood pressure medicines.
Before you start
Does anyone need a doctor's OK before this capsule?
Beta-alanine alone at 40 mg raises no specific warning in our sources. The capsule as a whole does, so the bottle's general rules still apply.
- Under 18, pregnant or nursing: the bottle sends you to a physician before use.
- Anyone with a known medical condition: same label instruction.
- Anyone on heart, blood pressure, nitrate or ED medicine: ask because of the arginine, not the beta-alanine.
The full list sits on the side effects and interactions page.
Fair verdict
Is beta-alanine a strength or a weak spot in Memodyne?
Harmless at this amount, honestly printed, and hard to justify for memory.
In its favor
- Exact amount printed, not hidden in a blend
- Far below the 800 mg tingle threshold
- Gram doses looked safe for up to 8 weeks
Against it
- One-fortieth of the lowest studied daily amount
- Studied for exercise, with mixed results even there
- No stated purpose in a cognitive formula

FAQ
Memodyne beta-alanine questions
Is there evidence that beta-alanine sharpens focus?
Not in any source we cite. The NIH review covers beta-alanine only for short, intense exercise, with mixed results (NIH ODS, Exercise supplements). No trial of Memodyne has been published, and 40 mg is far below any amount studied.
How much beta-alanine is in one Memodyne capsule?
40 mg, printed as "Beta Alanine" on the last line of the Supplement Facts. Sports research used 1.6 to 6.4 g a day, so one capsule is about one-fortieth of the lowest daily amount tested (NIH ODS, Exercise supplements).
At what dose does beta-alanine cause tingling?
Around 800 mg or more taken at once. The prickling spreads over the cheeks, neck, hands and chest, then fades in 60 to 90 minutes. It is not considered harmful (NIH ODS, Exercise supplements). Memodyne's 40 mg is one-twentieth of that mark.
Why is beta-alanine known as a workout supplement?
The body uses it to build carnosine in muscle, which helps buffer acid during hard, short efforts. Nearly all trials test sprints, rowing or lifting (NIH ODS, Exercise supplements). That is the setting where it was studied, not memory.
Is it safe to take beta-alanine every day?
Daily gram doses looked safe for up to 8 weeks in sports research (NIH ODS, Exercise supplements). Longer use is less studied. At 40 mg a day the amount is tiny, but the rest of the capsule, especially L-arginine, deserves a medicine check.
Can I take Memodyne with my pre-workout?
The beta-alanine adds only 40 mg, so it barely changes your total. Check the pre-workout for caffeine and other stimulants, and if you use heart or blood pressure pills, clear Memodyne's L-arginine with your doctor.
