Nutricost Pure L-Citrulline (Base) Powder (250 Grams) 3g Per Serving

This product works as advertised. It has improved my blood pressure, and I believe it has also enhanced my endurance and performance in sports such as basketball, cycling, and other activities I enjoy with my wife. It has a very mild taste, which is easily masked by dissolving it in flavored seltzer.

This is easily one of the best L-Citrulline supplements I’ve tried. Nutricost keeps it simple—pure, unflavored, and no unnecessary fillers. It mixes well in water or a pre-workout, and because it’s unflavored, it doesn’t change the taste of anything you add it to. I’ve noticed a big improvement in my workouts since using it—better pumps, better endurance, and quicker recovery. You definitely feel the difference when you take it consistently. The value is also excellent. You get a lot of servings for the price, and the scoop is accurate, which makes dosing easy. The container seals well, the powder is fine and blends smoothly, and the overall quality feels very clean and reliable. If you’re looking for a straightforward, effective L-Citrulline with no nonsense, this is the one. Highly recommend!

I'm running 6g daily split into two 3g doses — first thing on waking in water on an empty stomach, second dose mid-morning in an electrolyte drink. Nutricost's pure base powder dissolves cleanly with no fillers or additives, which matters when you're stacking multiple compounds. On training days I swap the electrolyte drink base from water to seltzer and take it 30-60 minutes pre-workout fasted. The carbonation serves a dual purpose — it aids creatine monohydrate uptake without needing a sugar carrier, keeping the stack insulin-neutral. Creatine HCL doesn't need the assist but costs significantly more — seltzer solves the bioavailability problem cheaply. The L-Citrulline in that pre-workout window also primes the NO pathway before the training stimulus hits. I'm combining this with two forms of resveratrol — Toniiq 500mg Blend and a Resveratrol Complex 500mg — timed across my midday doses. The resveratrol supports the NO pathway from a different angle and the combination appears synergistic. Within 3 days I noticed measurable improvements in peripheral circulation — specifically increased fullness and heaviness in the genital region, which for men researching nitric oxide support is a relevant and honest data point. This isn't placebo — the mechanism is real. L-Citrulline converts to L-Arginine in the kidney more efficiently than supplementing L-Arginine directly, driving nitric oxide production and vasodilation. Product quality is clean, doses well, no GI issues even in the electrolyte drink or pre-workout seltzer mix. If you're researching NO support seriously, the split-dose approach and training day timing both matter.

Debating/researching what brand to buy? I did the same for many,many days on supplements. Read below! I love that Nutricost tests all their products. You can literally contact them, with the LOT# on the bottle and they will send you test results. Why is that important? Many companies for one do not provide tests results if asked, you will usually get ignored or receive a generic response. It is also important because a lot of supplements can have heavy metals/contaminates in them and there is no warning of this. An example would be, almost all Ceylon Cinnamon across the world will have some type of contaimenants no matter what. I purchased some from Nutricost, contacted them about what tests have been done, they asked for the LOT# on the bottle and I received the test results the next day. The tests showed all levels of contaimenants were VERY low / in the range we're the body will not be effected. Many spices have contaimenants so keep that in mind! We tend to cook with them and have no idea. Make sure to look up Third Party Heavy Metal Spice test results, you will find a few lists of which brands are okay to buy. One of the very few Supplement Companies I trust! BUY NOW! :)

Taste is alright, you can tell there’s slightly more impurities than other brands I’ve had but pumps are still through the roof and it’s cheaper anyways

Been taking this daily for a couple of weeks now, it does take a bit to help but it's doing what I wanted it to do.

Great value and comes with a scoop for easy 3gram serving. Works for me.

Great for workouts! Mixes easily and boosts endurance. Pros: Clean formula, noticeable results. Cons: Slightly bitter taste.

👍🏼👍🏼

A noticeable difference in work outs. Great product

Producto 100% recomendable , cumple con lo especificado , aplicando la dosis exacta !

まだ飲み始めなので、効果は分からないので、★１つ減らしてます。 海外発送ですが、１週間程度で到着しました。 朝に小さじ１杯弱程度摂取してますが、市販のサプリの金額と比較しても コスパはいいと思います。 毎月購入とかにもならないと思います。 年に３～４回程度の購入になるなら、リピすると思います。

This is the best L-Citrulline on the market! I've tried several brands, including overpriced flavored brands. This is by far the best. It only has pure, clean L-Citrulline powder; no flavors, additives, or fillers. I tried brands with flavors and other sugar substitutes, and they would either upset my stomach when I took high doses or give me a headache. This causes no side effects and gives me a great pump and allows for getting an extra rep or two with the same weight. It also helps increase blood flow. I notice if I take a full scoop or scoop and a half, then I'll be "ready for action" in the bedroom as well. So its great for men because it makes it easier for ALL muscles to pump up! It's also at a great price !
