In short
What is Memodyne and what kind of supplement is it?
Memodyne is a dietary supplement capsule sold as a "Cognitive Support Formula". Four of its seven lines are forms of L-arginine and L-citrulline, amino acids the body uses to make nitric oxide.
The sales page links that to blood flow, memory and focus. Research on these amino acids, though, comes mostly from exercise studies at gram doses, and no study of the Memodyne formula has been published (NIH ODS, Exercise supplements).

Order nowDose reality check
Is the dose in Memodyne enough?
No, not compared with research. One Memodyne capsule holds a fraction of the smallest doses studied, and those studies were about exercise, not memory. The bars below show each amount against that range.
What this means
Athletes given 2 to 20 grams of arginine daily typically showed no rise in nitric oxide or circulation (NIH ODS, Exercise supplements). Mayo Clinic reviews L-arginine for the heart and blood vessels; memory is not on its list (Mayo Clinic, L-arginine). Niacin helps memory only when someone is truly deficient (NIH ODS, Niacin). See how the formula is supposed to work.
Name check
Is Memodyne the same as Melodyne, Namenda or memantine?
No. Memodyne is a supplement capsule, Melodyne is audio software, and Namenda (memantine) is a prescription medicine. Search engines mix up the three names, but only Memodyne is the amino acid capsule on this site.
Supplement
Memodyne
The capsule on this site: arginine, citrulline, beta-alanine, niacin and calcium. Sold without a prescription.
Software
Melodyne
Audio editing software for music. Searches for "Memodyne price" often land on it by mistake.
Prescription drug
Memantine (Namenda)
A prescription medicine for Alzheimer's disease. Memodyne is not a substitute for it, and you should never swap one for the other.
Several other web shops also sell under the Memodyne name. Before you pay anywhere, compare the panel with the one above.
Ask first
Memodyne side effects: who should check with a doctor first?
Memodyne side effects matter most for people on heart, blood pressure or blood sugar medicines, because of L-arginine. The label also asks anyone pregnant, nursing, under 18 or with a known medical condition to ask a physician first.
| Situation | Why it matters | Source |
|---|---|---|
| Heart attack in the recent past | Mayo Clinic says L-arginine is not recommended; deaths may rise in this group | (Mayo Clinic, L-arginine) |
| Blood pressure tablets | Blood pressure may drop more than intended | (Mayo Clinic, L-arginine) |
| Nitrates for chest pain, or sildenafil | Risk of very low blood pressure | (Mayo Clinic, L-arginine) |
| Blood thinners or diabetes medicine | Bleeding risk; blood sugar may fall | (Mayo Clinic, L-arginine) |
| Potassium-sparing diuretics | Potassium can build up | (Mayo Clinic, L-arginine) |
| Pregnant, nursing, under 18, or a known condition | The bottle asks you to see a physician before use | Label |

Claims vs evidence
Does Memodyne work? Does it improve memory?
Nobody can say for this exact formula, because no published trial has tested Memodyne. Here is what the research on its ingredients supports, and what it does not.
Sales page
"Increase cerebral blood flow"
The idea leans on nitric oxide, yet gram doses of arginine mostly left it unchanged in sports research (NIH ODS, Exercise supplements), and a capsule holds milligrams.
Sales page
"Protect neurons from oxidative stress"
None of our sources show this for arginine, citrulline or beta-alanine in people.
Research
Niacin and memory
Severe niacin shortage causes memory loss (NIH ODS, Niacin). If your diet covers niacin, extra adds little.
Not a treatment
Memodyne is not shown to stop, delay or undo dementia or Alzheimer's disease. Book a memory checkup rather than waiting on a capsule (NCCIH, Supplements for cognition).
Each claim is scored on the benefits page; a fair trial plan sits on the results timeline.
Verdict
Is Memodyne worth it? Pros and cons

No question matches. Try another word, or call the order desk.
What are the Memodyne ingredients?
Memodyne lists seven ingredients, each with an amount: niacin 7.5 mg NE, calcium 18 mg, L-arginine 200 mg, L-arginine AKG 200 mg, L-citrulline HCl 100 mg, L-citrulline malate 100 mg and beta-alanine 40 mg. They come in a hypromellose capsule.
Is Memodyne legit, and is this the official website?
Memodyne is a real, labeled dietary supplement with all seven amounts printed on the label. This site is run by a USA authorized retailer, not the maker. The label names Gex Corporation LLP in Ogden, Utah as distributor.
Is Memodyne the same as Namenda or Melodyne?
No. Namenda (memantine) is a prescription Alzheimer's drug, and Melodyne is audio software. Memodyne is a supplement with amino acids and niacin. Never stop or swap a prescribed medicine for a supplement.
What is Memodyne?
Memodyne is a dietary supplement sold as a Cognitive Support Formula. Each vegetable capsule has niacin, calcium, L-arginine, L-citrulline and beta-alanine, with every amount printed on the label. A bottle holds 30 capsules.
Does Memodyne work?
Nothing here shows that it does. The amino acids in it were tested for exercise, at doses far above one capsule, rather than for memory. The 60-day refund window gives you time to try it and decide.
Does Memodyne have side effects?
Tingling is very unlikely, since Memodyne has 40 mg of beta-alanine and tingling shows up around 800 mg or more in one dose. The main caution is L-arginine, which can send blood pressure too low when combined with blood pressure pills, nitrates or sildenafil. Ask your doctor first if you take any of those.
Who should not take Memodyne without asking a doctor?
The label asks anyone pregnant, nursing or under 18, or with a known medical condition, to ask a physician first. L-arginine can also clash with blood pressure pills, nitrates, sildenafil, blood thinners and diabetes medicine (Mayo Clinic, L-arginine). Ask your doctor first.
Does the FDA approve Memodyne?
Supplements, including Memodyne, are not FDA approved before they go on sale (FDA, Supplement Q&A). The "FDA registered facility" badge on some pages means registration, not approval (FDA, Approval myths).
How do I take Memodyne, and when?
Take one capsule a day with 8 oz of water, 20 to 30 minutes before a meal, per the label. The sales page leans toward mornings, so before breakfast is the simple choice. A bottle of 30 capsules lasts a month.
How much does Memodyne cost?
Six bottles for $294 works out to $49 a bottle and ships free in the U.S. Three bottles are $207, and two bottles are $158 plus shipping. All prices.
Where can I buy Memodyne?
Our order buttons open the Memodyne sales page. Our searches found no Walmart or Amazon listing, and marketplace sellers are outside our control. Compare any panel with the label shown here before you pay. Buying safely.
How do I get a Memodyne refund?
The sales page asks for at least 30 days of use before a claim. Call +1 (302) 200-3480 with your order ID within 60 days of purchase, then send the bottles back by a tracked service. Guarantee details.
