L-Arginine
Nitric oxide precursorAn amino acid the body converts into nitric oxide, the signalling molecule that widens blood vessels.
Studied for: blood flow and vascular function.

Most cognitive supplements are herbal. They reach for ginkgo, bacopa, lion's mane or ginseng — plants with long traditional histories and research bases ranging from substantial to almost nothing. MemoHoney goes a different way entirely.
Four of its six ingredients are amino acid compounds tied to one mechanism: nitric oxide production and the vasodilation that follows. Nitric oxide signals the smooth muscle in blood vessel walls to relax, widening the vessel. The body makes it from L-arginine.
The formula feeds that pathway from several directions — arginine directly, an absorption-optimised arginine form, and two citrulline compounds recycled back into arginine over a longer window. Niacin and beta-alanine cover cellular energy and antioxidant capacity respectively.
This is the most important thing on the page, and we would rather lead with it than tuck it away at the bottom.
The manufacturer does not publish per-ingredient amounts. You can see what is in the bottle but not how much of anything, which means nobody outside the company can compare the formula against published research or against a standalone product.
That matters here more than it would elsewhere, because these particular compounds have well-characterised effective ranges. Citrulline research typically uses several grams per serving. Beta-alanine studies commonly run to multiple grams daily over several weeks. Whether one capsule containing six ingredients delivers anything approaching those figures cannot be determined from the outside.
The practice is legal and extremely common. It is still a genuine limitation, and any site describing a formula as "clinically dosed" without publishing the numbers is asking you to take that entirely on trust.
We have tried to keep three things apart that supplement marketing usually blends. Established biochemistry means a mechanism is textbook — niacin's role in NAD+ production, for instance. Research in another context means good evidence exists but for a different application, which describes much of the arginine and beta-alanine literature. Demonstrated cognitive benefit means human trials show an effect on memory or focus, and it applies to less of this formula than any seller would like.
Each links to a page covering what it is, the research, why it is included and the cautions that apply.

Read the full pageThere is a structural trade-off in any combination formula and it is worth stating plainly. A capsule holds a fixed volume. Every ingredient added takes a share of it, so a six-ingredient product cannot deliver a research-scale dose of all six. That is arithmetic rather than criticism, and it applies to every blend on the market.
What you gain is convenience and a coherent single mechanism approached from several angles. What you give up is depth in any one component, and the ability to verify what you are actually getting.
So if your interest is a specific compound at a specific dose — several grams of citrulline, say — a standalone product will serve you better and cost less. If you want general daily support alongside an existing routine and you value the single capsule, a blend is a reasonable format. Choose with that trade-off in view.
