- Reviewed in Canada on May 19, 2025Every person will react differently to each supplement. My results with this L-citrulline were no negative side effects, but I have no way of measuring benefits directly.
After taking this for about a month, I found no noticeable drawbacks to taking this L-citrulline.
No stomach upset, and no noticeable other side effects. I take this to improve nitric acid, to supposedly improve circulation.
I have no way to directly measure this, but I take it based on published research.
The medicinal ingredient label on the bottle says 2g L-citrulline in a serving. One scoop is one serving, and that is what I took.
I found taking 1 scoop daily gave me no stomach upset at all.
The powder is odourless and tasteless.
This L-citrulline has a NPN number, approving it for sale in Canada by Health Canada. I can't speak to how rigorous the agency's testing is, but at least another set of eyes have been on this product before it was sold.
I can't say if I directly received benefit from this product, but I take it based on research. Long term use and repeated blood tests and other medical tests are probably the only ways to confirm efficacy in your own body.
At the bottles' recommended 1 scoop a day, it will last over 3 months.
Considering the price, cited benefits, and how long a bottle lasts, I would order again for myself.
- Reviewed in Canada on April 5, 2025Verified Purchasegood product.. but nothing special
- Reviewed in Canada on May 20, 2025It is not possible to objectively evaluate the benefits or the efficacy of supplements through ordinary home use; so, I will not get into this product's effectiveness, and you can search the Internet for the benefits of the main ingredient of this product: L-Citrulline.
It comes in powder form. It is unflavored and it mixes well.
It is clearly indicated on the bottle that it was made in Canada, and it has an NPN number (Natural Product Number) that can be used to confirm that it was licensed in April 2024, and the license was revised quite recently in April 2025. There are 3 brand names associated with the license, and the license holder is O Laboratoire Nutraceutique.
Similar to the label on the product, the NPN product information page lists only a single medicinal ingredient: L-Citrulline. Risk information on the NPN page is as follows:
"Cautions and Warnings
Consulter un praticien de soins de santé/fournisseur de soins de santé/professionnel de la santé/docteur/médecin avant d'en faire l'usage si vous avez une maladie du foie ou des reins. Consulter un praticien de soins de santé/fournisseur de soins de santé/professionnel de la santé/docteur/médecin avant d'en faire l'usage si vous êtes enceinte ou si vous allaitez."
It comes in a container with 100 scoops/servings in it. The recommended dosage is 1 scoop, 2-3 times a day, which should have the bottle last for 30 to 50 days if you follow the recommended dosage. The price was $30 CAD at the time of writing.
While I cannot confirm the claimed benefits or the product's efficacy, I see no reason to cut any stars from my rating. I appreciate that it was made in Canada and that it comes with a proper NPN number on the bottle.
- Reviewed in Canada on May 2, 2025First time trying L-Citrulline.
I like the taste, it's a good change, to me it tastes fizzy, like carbonated-fresh, almost slight citrus to it, refreshing and unique. It's pleasant.
This is suppose to help health through nitric oxide support. And nitric oxide helps with vasodilation, endurance in gym, circulation etc, it's a key component to overall health.
However, it's L-Citrulline Malate that helps more in gym (strength/endurance) and energy. But Malate form you get less L-citrulline since its a blend and does not give extra advantage for overall cardiovascular support - that L-citrulline is the core driver of.
And L-Citrulline may be better than L-Arginine for Arginine/nitric oxide levels.
I have been taking it on an empty stomach without food for over a week. I don't notice anything substantial or negative, maybe I do notice a pump, as L-citrulline is something I think people may feel effects within several days. Some effects of cardiovascular/blood pressure take longer though of a few weeks.
The product has no fillers and priced low and typical.
- Reviewed in Canada on April 30, 2025This small tub of L-Citrulline comes in at about a mid level in pricing/capacity. Not quite as cost efficient as a larger format this is priced a little higher than some other options. It has basically zero taste though and blends in quite well without clumping up. Bull is made in Canada and carries the NPN number 80130498 and is vegan as it is simply pure Citrulline.
Bottle lists it as 100 servings though this assumes a 2g scoop a few times a day. Ive seen people often use higher amounts so depending on your personal dosage this size tub might not last so long. Personally I am enjoying it so far and it seems to be working for me.

- Reviewed in Canada on May 2, 2025As I approach my 50s, looking to supplements to diet to remain healthy, and blood circulation and blood pressure is a concern.
You’ve probably already researched the supplementing with L-citrulline and ways to boost nitric oxide for blood flow, so this is more about the product itself.
Just pure L-citrulline, add a scoop to whatever shake, smoothie, drink you have in your supplement stack. It’s flavourless and mixes well with anything which is great it allows for other things to provide flavour and texture and doesn’t throw anything off, though to be honest I’ve never taken it on it’s own, I can say I pretty much don’t notice it when added - this is a good thing.
Made in Canada with an NPN number is also important to me
At 100 servings per container, this is a pretty generous supply
