Vigorus vs L-Citrulline Powder: Which One Fits Your Goal?
Quick answer
Plain L-citrulline powder gives you one ingredient at a dose you can measure, and studies used about 3 to 9 grams a day. Vigorus gives you one capsule with eight ingredients, including 20 mg niacin and 11 mg zinc, but its citrulline sits inside a 570 mg blend with no printed amount. Choose powder for a studied citrulline dose. Choose Vigorus for a simple one-capsule routine.
What is the difference between Vigorus and L-citrulline powder?
They are built for different jobs. L-citrulline powder is a single ingredient. Vigorus is a mixed formula in one capsule, led by citrulline but sharing its space with five other blend ingredients plus a vitamin and a mineral.
| Point | Vigorus | Plain L-citrulline powder |
|---|---|---|
| Form | 1 vegetable capsule a day | Powder you measure and mix |
| Ingredients | 8: niacin, zinc and a 6-part blend | 1: L-citrulline |
| Citrulline amount | Not printed; part of a 570 mg blend | Printed on the tub, set by your scoop |
| Exact amounts shown | 2 of 8 (niacin 20 mg, zinc 11 mg) | The single ingredient |
| Sales aims | Libido, circulation, healthy testosterone in the normal range | Depends on the brand |
| Refund | 60-day money-back guarantee | Depends on the seller |
Neither is a medicine. Both are dietary supplements, and the choice comes down to what you want to control.
How much citrulline does each one give?
This is the biggest gap. Citrulline studies gave about 3 to 9 grams a day (NIH ODS, exercise). The whole Vigorus blend is 570 mg, which is 0.57 grams, and six ingredients share it.
- 570 mgwhole Vigorus blend
- 3,000 mglow end of citrulline studies
- 19%most a blend of pure citrulline could reach
- 6ingredients sharing the blend
Even if the blend were all citrulline, one capsule would reach about 19% of the lowest study dose. It is not all citrulline, so the real share is lower. A powder lets you hit the studied range on purpose. Results with gram-dose citrulline still vary from study to study, as a 2022 review on aerobic exercise noted (Viribay et al., 2022). Our L-citrulline explainer goes deeper into those trials.
What does Vigorus add that plain powder does not?
Breadth. Vigorus puts several routes into one capsule, where a powder covers one.
- Zinc, 11 mg (100% DV). Zinc has a clear role in normal testosterone when intake is low (NIH ODS, zinc).
- Niacin, 20 mg (125% DV). A B vitamin used in turning food into energy.
- Pine bark extract. The circulation ingredient with the most human trials, though its amount here is not printed.
- Maca and saffron. The two desire ingredients in the blend, with small or limited trials.
- L-carnitine and grape skin. An energy-use compound and a source of plant polyphenols.
The trade-off is that only the zinc and niacin lines can be held to a number. See the ingredients page for each one.

What does L-citrulline powder offer that Vigorus does not?
Control and a printed dose. With a plain powder, the tub tells you how much citrulline is in each scoop. You can match a study dose, and you can change it with your doctor's input.
What you give up is everything else in the Vigorus formula. A citrulline powder holds no zinc, no niacin and no plant extracts, unless you buy those separately. You also have to measure and mix it each day, which some men find harder to keep up than a capsule.
How do the routine and cost compare?
Vigorus is one capsule a day with no time rule, so the routine takes seconds. The cost is easy to work out because one capsule covers one day.
| Pack | Upfront | Per day | Days |
|---|---|---|---|
| 2 bottles | $158 | $2.63 | 60 |
| 3 bottles | $207 | $2.30 | 90 |
| 6 bottles | $294 | $1.63 | 180 |
Powder prices vary by brand and tub size, so compare by the cost of the dose you plan to take, not by the tub. More detail on each Vigorus pack is on the pricing page.
Is either one safer?
Both touch the same pathway. Citrulline becomes arginine, then nitric oxide, which relaxes blood vessels. So the same caution applies to both, and it grows with the dose.
- If you take blood-pressure pills, a blood thinner or a nitrate, show the label to a clinician first.
- Do not stack a citrulline powder on top of Vigorus without asking a clinician.
- Vigorus is not for anyone under 18 or women who are pregnant or nursing.
- Take one Vigorus capsule a day. Two would push niacin to 40 mg, above the 35 mg upper limit for supplements.

Frequently asked questions
Does Vigorus contain enough citrulline to match the studies?
No. Citrulline studies used about 3 to 9 grams a day. The whole Vigorus blend is 570 mg, shared by six ingredients, so its citrulline is well below those doses. The exact amount is not printed.
Can I take Vigorus and L-citrulline powder together?
Some men add a separate citrulline powder, but both act on circulation. Check with a clinician first, especially if you take blood-pressure or nitrate medicine.
Is Vigorus sold as a powder?
No. Vigorus comes as vegetable capsules, 30 to a bottle, taken one a day. The capsule shell is hypromellose, a plant-based material.
Our view
If your goal is citrulline itself, at the doses researchers used, a plain powder is the more direct tool. If your goal is a simple daily habit with zinc, niacin and a spread of plant extracts in one capsule, Vigorus is built for that. Just know that its citrulline amount is not printed and the whole blend is small.
Whichever you pick, give it a steady, logged trial and change nothing else at the same time. Vigorus is a dietary supplement, not a medicine for any condition. Sexual or erection problems can be an early sign of heart disease or diabetes, so see a doctor if they are new.
