In one paragraph
Memodyne is a stimulant-free daily capsule aimed at adults who want steadier focus and want to see every milligram before they buy. The formula leans on nitric oxide precursors rather than caffeine, which is why the label reads like a circulation panel. Memodyne sells for $49 to $79 a bottle depending on the supply you take, ships from the authorized 2026 batch documented on this page, and carries a 60-day refund window that covers opened bottles.

The formula
What is inside each Memodyne capsule
Every active in Memodyne is printed with its own amount. There is no proprietary blend on the Memodyne panel, which means you can compare this label against a reference database line by line instead of guessing.
Nitric oxide precursors
Two arginine forms totalling 400 mg and two citrulline forms totalling 200 mg. Arginine is the direct substrate for nitric oxide synthesis; citrulline is the form the kidneys convert back into arginine, which is why Memodyne pairs them.[1]
Buffering amino acid
Beta alanine at 40 mg. This is a modest amount next to the doses used in sports research, and Memodyne does not claim otherwise. It sits on the panel as a supporting active rather than the headline.[5]
Declared micronutrients
Niacin 7.5 mg NE, which is 47% of the Daily Value, plus calcium 18 mg as calcium carbonate. Niacin is one of the few ingredients here with an established DV, so it is the easiest line on the Memodyne label to verify.[2]
| Ingredient | Per capsule | %DV | Why it is on the panel |
|---|---|---|---|
| Niacin | 7.5 mg NE | 47% DV | Vitamin B3, listed on the panel with an established Daily Value. |
| Calcium (as calcium carbonate) | 18 mg | 1.5% DV | Mineral carrier in the capsule matrix. |
| L-Arginine (base) | 200 mg | DV not established | Conditionally essential amino acid, a direct nitric oxide precursor. |
| L-Arginine AKG 2:1 extract | 200 mg | DV not established | Arginine bound to alpha-ketoglutarate, a second arginine form on the panel. |
| L-Citrulline HCl | 100 mg | DV not established | Amino acid the kidneys convert back into arginine. |
| L-Citrulline malate | 100 mg | DV not established | Citrulline paired with malic acid, the second citrulline form. |
| Beta alanine | 40 mg | DV not established | Amino acid best documented in exercise and buffering research. |
Other ingredients in Memodyne: Hypromellose (vegetable capsule), vegetable stearate, silicon dioxide. Declared active total: 665.5 mg per capsule. See the full label facts page.
Verification
Batch record for the 2026 production cycle
Every Memodyne bottle shipped from this portal comes out of one documented run. The record below is the same one you will find on the batch check page, and it does not change until the cycle closes. If the lot stamped on your bottle does not match, that bottle did not come from the authorized channel.
The purity figure and the screening results are presentation data for this cycle, published so a Memodyne buyer has something concrete to compare against rather than a badge with no number behind it.

Buyer feedback
What 3,148 verified buyers report
Memodyne averages 4.7 out of 5 across 3,148 verified United States purchases, with 1,204 written reviews inside that total. The Memodyne pattern is gradual rather than dramatic, and the pages below include the critical reviews as well as the positive ones.
5 out of 5
Four weeks in and the mid-afternoon slump is the thing that changed most. I still drink coffee, but I am not chasing a second cup at three o'clock.
5 out of 5
I bought it because the label lists real amounts. That is rarer than it should be. Whether it works for you is another question, but at least you can check what you are taking.
5 out of 5
Took the six-bottle supply. No jitters, no stomach trouble, and I sleep the same as before. That mattered to me more than a dramatic first week.

The distributor
Three commitments we publish
01
The label goes up before the offer
The printed Memodyne panel is on this site in full, with amounts, before you reach a price. If a formula cannot survive being read, it should not be sold.
02
One batch, one record
Each Memodyne production cycle gets a lot code, a purity result and a certificate number, published here and unchanged until the cycle closes.
03
Refunds are not a maze
Sixty days, opened bottles accepted, one email to start it. We do not ask why, and we do not route you through a retention script.
Why Bellrock Nutrition exists
Bellrock Nutrition Group, Inc. was set up in 2018 by a hospital pharmacist who spent years fielding the same question from patients at the counter: what is actually in this bottle, and how would I know. Most answers were buried in proprietary blends. The company was built around the opposite habit, distributing only formulas that print their amounts, and publishing the batch record on the same page that takes the order. Memodyne fits that rule, which is why we carry it.
We are a distributor, not a laboratory. The formula belongs to the manufacturer; our job is the United States channel, the documentation, the refunds and the support line. More about our company.
Answers
Common questions about Memodyne
What is Memodyne?
Memodyne is a once-daily cognitive support capsule sold in 30-count bottles. Each capsule carries 665.5 mg of declared actives, led by two arginine forms and two citrulline forms, plus niacin and a small amount of calcium. Memodyne is a dietary supplement, not a medicine, and every amount is printed on the panel rather than hidden inside a proprietary blend.
What is in Memodyne and at what dose?
One Memodyne capsule delivers L-arginine base 200 mg, L-arginine AKG 2:1 extract 200 mg, L-citrulline HCl 100 mg, L-citrulline malate 100 mg, beta alanine 40 mg, calcium 18 mg and niacin 7.5 mg NE. The other ingredients are hypromellose, vegetable stearate and silicon dioxide. Nothing on the panel is undisclosed.
Where can I buy Memodyne?
Only from this portal, memodyneofficial.com. The manufacturer routes United States Memodyne orders for the 2026 cycle through one authorized channel, so the bottle you receive is matched against the batch record published here. Memodyne is not stocked on Amazon, eBay, Walmart or in retail pharmacies.
Is Memodyne legit or a scam?
Memodyne is a real, shipped product with a printed label, a named distributor, a published refund window and a checkout handled by an established payment processor. The honest caveat is the one that applies to every supplement: it is not a drug, it is not FDA approved, and results vary. Buy it from this domain and the 60-day refund policy applies without argument.
How long does Memodyne take to work?
Most Memodyne reviewers who report a change describe it between week two and week four. About a quarter notice something inside the first fortnight. Amino acid intake is cumulative rather than acute, so a fair trial is one full bottle taken at the same time each day.
Is Memodyne FDA approved?
No. Memodyne is not FDA approved, because the agency does not approve dietary supplements at all. It is produced in an FDA-registered facility that operates under cGMP rules, and the statements on this site have not been evaluated by the Food and Drug Administration.
Why the Memodyne Official Website routes every order through one authorized portal
Single-channel distribution is not a marketing flourish for a supplement of this kind; it is the only way the batch record means anything. When a product is scattered across marketplace resellers, nobody can tell you which run a given bottle came from, how long it sat in a third-party warehouse, or whether the seal was ever broken. Consolidating the United States Memodyne channel into one portal means the lot code printed on your bottle can be matched against a record that is published rather than promised, and it means a refund request lands with the party that actually shipped the parcel.
The second reason is more prosaic: counterfeit and grey-market listings follow any supplement that sells. They copy the Memodyne label art, undercut the price by a few dollars and ship something nobody has tested. Because Memodyne is fulfilled only from this domain, a listing anywhere else is by definition outside the authorized 2026 distribution, and you do not have to judge it on look and feel. That is a cleaner test than trying to spot a fake bottle from a photograph.
How circulation actives relate to daily mental clarity
Read the Memodyne panel without the branding and it looks like a nitric oxide formula: arginine in two forms, citrulline in two forms, a little beta alanine. That is deliberate. Nitric oxide is a signalling molecule involved in vasodilation, and arginine is its direct substrate; citrulline is useful because a meaningful share of oral arginine is broken down before it ever reaches circulation, whereas citrulline is converted back into arginine downstream.[1] The reasoning behind the Memodyne formula is that the brain is an unusually blood-hungry organ, so support that starts with circulation is a plausible place to begin.
Plausible is the right word, and we will not upgrade it. The public evidence base for these amino acids is strongest in exercise and blood-flow research, not in cognition, and the amounts here sit below what most of that research uses.[1] Niacin is the one Memodyne line with a firm regulatory anchor, at 47% of the Daily Value.[2] If you want a formula that promises a measured jump on a cognitive test, this is not it. If you want a stimulant-free daily capsule with published amounts you can look up yourself, the panel holds up.[3]
What the 60-day guarantee actually covers
Sixty days from delivery, opened bottles included, on every Memodyne package size. That last part is what separates a usable guarantee from a decorative one, because a supplement you have not opened tells you nothing. In practice a fair trial is one full bottle taken at the same time each day, which leaves you a month of margin to decide. Start the return with one email to [email protected] and you get return instructions the same business day; there is no restocking fee and no retention call. The manufacturer's contracted retailer processes the refund to the original card, typically within five to seven business days of the parcel being received.
What the guarantee does not do is turn a supplement into a treatment. Memodyne supports a daily routine; it does not diagnose, treat, cure or prevent anything, and nobody here will tell you otherwise. If you take blood pressure medication, nitrates, or anything else that acts on blood vessels, talk to your doctor before adding a nitric oxide formula.[4]
