HoneyPezil Ingredients Explained: All Six, With Sources and Cautions

By the HoneyPezil Guide editorial team · Updated November 10, 2026 · 3 min read

The six at a glance

• L-arginine: amino acid that the body converts into nitric oxide. See the arginine guide.
• L-arginine AKG 2:1: arginine bound to alpha-ketoglutarate. See AAKG explained.
• L-citrulline HCl: a precursor recycled into arginine. See citrulline vs arginine.
• L-citrulline malate: citrulline paired with malate. See the two citrulline forms.
• Niacin (vitamin B3): a precursor of NAD+. See niacin and brain energy.
• Beta-alanine: the building block of carnosine. See beta-alanine and carnosine.

What is not published

The seller's order page does not give milligrams per capsule, the "other ingredients" or capsule material. Competitor and review sites sometimes list extra herbs or vitamins that do not match the seller's list; treat those as errors and rely on the bottle.

What the ingredients have in common

Four of the six feed the nitric-oxide pathway that helps regulate blood vessel tone; one supports cell energy; one builds an antioxidant dipeptide. The 2022 review of dietary supplements for nitric-oxide synthesis outlines the arginine and citrulline logic, mostly in cardiovascular and exercise contexts.

What the evidence does and does not show

Mechanism evidence is strong; outcome evidence for memory in healthy adults is thin. A short 1997 study found arginine infusion raised basal but not activated cerebral blood flow. The NIA emphasizes lifestyle for brain health.

Cautions in one place

Medicine interactions (blood pressure, nitrates, ED drugs, blood thinners), niacin flushing at high doses, beta-alanine tingling, pregnancy and under-18 use. See side effects and who should skip it.

How to verify

Compare the bottle's Supplement Facts panel with this list, and use the NIH guide to supplement labels and safety for reading it.

Why the combination, not just the parts

Four of the six ingredients overlap on purpose. Two arginine forms and two citrulline forms give the nitric-oxide pathway several routes in, while niacin and beta-alanine cover cell energy and antioxidant defence. That overlap is a design choice the seller explains; whether it outperforms a single well-dosed amino acid is untested in head-to-head trials.

Food equivalents

For perspective, a handful of nuts supplies arginine, a slice of watermelon supplies citrulline, and a serving of chicken or fish supplies niacin and carnosine. See foods that support brain blood flow. A capsule concentrates amounts that food spreads across the day.

A reading list

Start with the NIH niacin fact sheet, the MedlinePlus arginine page and the 2023 review of beta-alanine and cognition. Each links further to primary studies.

Questions worth asking the seller

Ask for the amount of each ingredient per capsule, the form of niacin, the capsule material, the manufacturer's name, a recent certificate of analysis and any third-party testing. A transparent seller can answer within a few days. If answers are vague, weigh that when deciding.

How to compare against research doses

Once you have the numbers, look up the doses used in studies on each ingredient. If your capsule contains a small fraction, the research may not apply; if it contains very large amounts, safety limits (such as the niacin upper limit) matter more. Either way, you are now evaluating the product on facts.

Ingredient myths to ignore

That more is always better, that "natural" means safe, that proprietary blends are superior and that a famous-sounding name equals proof. None of those hold up.

Ingredient summary table in words

• L-arginine: nitric-oxide substrate; found in nuts, meat, dairy; watch blood pressure and medicine interactions.
• L-arginine AKG 2:1: arginine salt with a Krebs-cycle compound; sports heritage; same cautions.
• L-citrulline HCl: recycled to arginine; found in watermelon; generally well tolerated.
• L-citrulline malate: citrulline with malate; exercise research; occasional stomach upset.
• Niacin: vitamin B3, NAD+ precursor; flushing at higher amounts; upper limit 35 mg from supplements.
• Beta-alanine: carnosine precursor; tingling is common; brain data preliminary.
• e this list as a checklist when you read the bottle. Tick off each ingredient, write the milligrams beside it and note anything not on the list. If extra ingredients appear, research them too. If amounts are missing, ask the seller. This turns a marketing page into a concrete, comparable record you can show a pharmacist.
