Nutricost Pure L-Citrulline (Base) Powder (250 Grams) 3g Per Serving | 83 Servings, Gluten-Free, GMO-Free

Solid pump and endurance boost. Mixes pretty well and has no weird aftertaste. I’ve been using it before jump rope, ring work, and basketball and definitely notice better blood flow and less fatigue during longer sessions. Good value for the amount you get.

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.

This is the stuff that works. If you do the research on citrulline, arginine, or citrulline maleate, it is citrulline that has all the clinical results. The taste is not that noticeable if any, but there is a slight smell. Scoop is perfect size for even narrow bottles. Can is far easier than a back for convenience. This nutricost product allows you to dose clinically to achieve the desired affects without loading up on sucralose or garbage like beta-alanine or glycerol. Butricaprs has great QC as well

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!

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

Excellent product! Having been a professional fitness competitor for many years and using countless different brands and types of supplements, I can say for certain that I’m an avid Nitricost fan! Dissolves instantly in water and has zero taste. Stacks well with L-Tyrosine, Acetyl L - carnitine, and Taurine. And don’t forget your electrolytes! Great for fitness enthusiasts as well as those who are simply trying to maintain good clean cardiovascular health without the dangers of caffeine and other harsh ingredients.

Helps with blood pressure, and this product dissolves easily in water, with no that taste. Pretty much tasteless.

Great product, I especially feel it on Pull days at the gym. On the flavor vs. no flavor debate: yes, if you concentrate in, say, only 1/4 cup of water, then yeah you can taste it. But if you mix it into, say, 1 cup of water, then no, flavorless, perfectly fine. Enjoy the pump, and happy, safe training. 👍

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 !

-Well sealed. Came with a clear plastic wrap around the lid, as well as a foam paper protective seal on the inside. -Mixes well. -Taste is okay. Mixed half a teaspoon in water. It has a mild bitter taste, but not bad at all. -Does it actually improve performance? Who knows.
