Maxentra names its active ingredients, which many products do not. What it does not publish is how much of each there is. These are general descriptions of the ingredients, not claims about Maxentra’s own results.
| Ingredient | What it is | What research suggests |
|---|---|---|
| L-Arginine HCL | Amino acid, nitric oxide precursor | Studies use grams per day; can lower blood pressure; mixed results |
| L-Arginine AKG | Arginine bound to alpha-ketoglutarate | Sold for sports use; evidence for performance benefit is limited |
| L-Citrulline Malate | Citrulline with malic acid | Small studies at about 3,000–8,000 mg show modest exercise effects |

Ask the seller in writing for the Supplement Facts panel before you pay. Then take it to a doctor or pharmacist, especially if you use nitrates, ED medicine, blood-pressure medicine or blood thinners. See the ingredient-by-ingredient guide.
