L-Arginine 200 mg
The direct building block of nitric oxide, the molecule that helps blood vessels relax and widen so blood can flow more freely.
The short version
What Is Maxentra, In Plain English?
Maxentra is a men's performance dietary supplement that supports healthy blood flow, energy and stamina. You take 1 capsule a day, 20 to 30 minutes before a meal, with a glass of water. Each capsule has 400 mg of L-arginine (two forms), 200 mg of L-citrulline (two forms), 40 mg of beta-alanine, plus niacin and calcium. It sells for $49 to $79 per bottle on the official site, with a 60-day money-back guarantee.
The best part of this offer is how little risk you carry. We read the seller's written return policy, not just the sales page: you have 60 days from purchase to return it for any reason, and the bottles can be opened or even empty.
Is this you?
When You Don't Feel Like Yourself Anymore
It rarely happens overnight. One day you notice that the drive you used to take for granted is not quite there:
- You run out of steam earlier than you used to, at work and at home
- Workouts feel harder and the "pump" you remember is gone
- Your confidence takes a hit, even if you never say it out loud
- Cold hands and feet, a sign that circulation isn't what it was
- You keep telling yourself "it's just age"
Blood flow matters for all of it. Your body relies on nitric oxide to help blood vessels relax and widen, and nitric oxide production naturally drops as men get older. That is the gap Maxentra is built for: a simple daily capsule of the two amino acids your body turns into nitric oxide.
One honest note first
If you take medication for your heart, blood pressure or erectile dysfunction, talk to your doctor before adding Maxentra. Arginine and citrulline can add to the effect of those medications.
The basics
What You Are Actually Buying
Maxentra comes as a bottle of 30 vegetable capsules. The label says 1 capsule a day, so one bottle lasts a month. No powders to mix, no shaker bottle and no handful of pills.
How it compares with a typical men's performance formula
| Maxentra | Typical formula | |
|---|---|---|
| Daily routine | 1 capsule a day | Often 2 to 4 capsules |
| Label | Every dose printed | Often a "proprietary blend" with hidden amounts |
| Approach | Nitric oxide amino acids (arginine + citrulline) | Often exotic herbs with stimulants |
| Refund window | 60 days, any reason | Often 30 days |
Who it is a good fit for
Adult men who want simple daily support for blood flow, energy and performance, who prefer a stimulant-free formula they can read line by line, and who like a long refund window to test it properly.
Who should ask a doctor first
Anyone taking medication for the heart (especially nitrates), blood pressure or erectile dysfunction, anyone with low blood pressure, kidney or liver disease, and anyone under 18. The label also asks anyone with a known medical condition to consult a physician first.
Inside the bottle
Maxentra Ingredients: The Real Label
Here is the Supplement Facts panel exactly as printed on the bottle, so you know precisely what you are taking.
Per 1 capsule: niacin 7.5 mg NE (47% DV), 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. Other ingredients: hypromellose (vegetable capsule), vegetable stearate and silicon dioxide. No caffeine, no stimulants, no herbs.
What each ingredient does
L-Arginine AKG 200 mg
Arginine bonded to alpha-ketoglutarate, a popular form in sports nutrition that is gentler on the stomach.
L-Citrulline HCl + Malate 100 mg + 100 mg
An amino acid found in watermelon. The body converts it into arginine, which keeps nitric oxide production going for longer.
Beta-Alanine 40 mg
An amino acid used in sports formulas for muscular endurance during exercise.
Niacin 7.5 mg · 47% DV
Vitamin B3, which helps the body turn food into energy.
Calcium 18 mg
A small amount of calcium carbonate, a common support mineral in capsule formulas.
What to know about the doses
Unlike many men's formulas, Maxentra prints the exact amount of every ingredient, so nothing hides behind a "blend". It is a gentle daily dose: 400 mg of arginine and 200 mg of citrulline per capsule, smaller than the multi-gram amounts used in some sports studies. Think of it as steady daily support rather than a pre-workout powder.
Daily routine
How To Take Maxentra
- Take 1 capsule a day with an 8 oz glass of water (the label's directions)
- For best results, take it 20 to 30 minutes before a meal
- Do not take more than the recommended dose
- Give it at least 30 days of daily use before judging. That is exactly why the 60-day guarantee is useful
How long does a package last?
Each bottle has 30 capsules, so one bottle is one month. 2 bottles cover 60 days, which matches the guarantee window. 3 bottles cover 90 days and 6 bottles cover 180 days.

The big question
Is Maxentra Legit Or A Scam?
Maxentra is a real product sold through a real checkout. Orders go through BuyGoods, an established US checkout used by many supplement brands. The label says it is manufactured in the USA with globally sourced ingredients, and the seller publishes a written return policy with a physical return address in Ogden, Utah, plus a US phone line for order questions.
Maxentra is a new product, so you will not find years of independent reviews yet. That is exactly why the written 60-day guarantee matters here.
Three things to ignore on ads and sales pages
- "FDA Approved" badges. The FDA does not approve dietary supplements. Any page showing that badge is getting it wrong.
- Celebrity or doctor ads. If you saw a famous face "recommending" a men's supplement in a video ad, be careful: fake endorsements are common in this category. Buy because of the label and the guarantee, not a face.
- "Instant" or "overnight" promises. Amino acid formulas work as daily support over weeks, not as a pill that acts in minutes.
Where to buy it
Only through the official site. Anything bought elsewhere is not covered by the 60-day guarantee.
No surprises
What Happens After You Click "Buy"?
- You pick 2, 3 or 6 bottles on the official order page
- You pay once on the secure BuyGoods checkout. It is a one-time charge, with no subscription and no automatic rebill
- You will likely see one or two extra offers for more bottles at a lower price. They are optional, and you can simply click "No thanks"
- You get an order confirmation email. Save it: it is your proof of purchase date for the guarantee
- Shipping is free in the US on the 3 and 6-bottle packages

Does Maxentra Have Side Effects?
The label lists no side effects, and arginine, citrulline and beta-alanine are widely used amino acids. A few practical points:
Talk to your doctor before taking Maxentra if you take heart medication (especially nitrates), blood pressure medication or erectile dysfunction medication, if you have low blood pressure, kidney or liver disease, or if you are under 18.
Some people notice mild stomach upset with arginine at first; taking it with a full glass of water, before a meal, helps. Beta-alanine can cause a harmless tingling in some people, although 40 mg is a small amount. Do not exceed the recommended dose. Maxentra is a dietary supplement: it is not intended to diagnose, treat, cure or prevent any disease.

The guarantee, in the seller's own terms
Maxentra carries a 60-day money-back guarantee from the date of purchase, for any reason. We read the written return policy: contact the support team first for return instructions, then mail back all the bottles, opened, unopened or empty, with the packing slip and a note showing your name, email and order ID. The refund goes back to your original payment method once the package is received, and banks usually take 5 to 10 business days to show it. Return postage is paid by you.
Refund terms read from the seller's published return policy in October 2026. Keep your order confirmation email and screenshot the policy on the day you order.

Before I recommend anything, I do the homework most buyers don't have time for:

- Read the written return policy, not just the sales promise
- Worked out the real cost per day for each package
I write the way I'd talk to a friend: what I like, the catches up front, and who should check with a doctor first.
