It works for ED. Just take a 30 minutes before.
This is fantastic stuff except the pills are a little bit big in size. Do I feel better sort of it does help with my ED I think but L arginine doesn’t last that long and the ingredient seem like they’re high-quality. Energy level but more for ED. I don’t have any stomach discomfort when I take it and it doesn’t give me jitteriness or anything weird like that. Overall I good value.

High-Quality L-Arginine Supplement - Excellent Value!
Effectiveness: This NOW Foods L-Arginine supplement has been excellent for supporting my fitness goals and overall cardiovascular wellness routine. The 1,000mg dosage provides substantial amino acid support that I've incorporated into my pre-workout regimen for enhanced performance and recovery. I appreciate having a pure, high-potency L-Arginine supplement that serves as an effective nitric oxide precursor for supporting healthy circulation and exercise performance. The tablet format is convenient for consistent daily dosing, and I've found the timing flexibility helpful for optimizing my supplementation around workout schedules. The 120-tablet bottle provides excellent coverage for extended supplementation without frequent reordering. Quality: NOW Foods has built a solid reputation for producing reliable nutritional supplements, and this L-Arginine maintains their quality manufacturing standards. The tablets are well-formed and dissolve properly without causing stomach upset when taken with adequate water as recommended. The amino acid appears to be pure and well-absorbed, providing the bioavailability needed for effective supplementation. The manufacturing quality ensures consistent potency across different bottles, giving me confidence in reliable results. The packaging protects product integrity and maintains freshness throughout the bottle's shelf life. Value for Money: This L-Arginine supplement provides outstanding value when you consider the high potency and generous tablet count at a very competitive price point. The 120-tablet supply offers excellent coverage for four months of daily supplementation, making the cost per dose very economical compared to smaller bottles or premium brands. The quality and effectiveness make this far more cost-effective than trying multiple inferior products or dealing with inconsistent amino acid sources. The reliable manufacturing and proven results make this a smart investment for serious fitness supplementation and cardiovascular support. This L-Arginine supplement has become a valuable part of my fitness nutrition routine and provides reliable amino acid support. Highly recommend consulting with healthcare providers about incorporating L-Arginine supplementation into your wellness and fitness routines!

Good product but...
Overall solid product as you are using one pill instead of the usual 2-3 pills. The drawback? The pills are pretty big, and I feel like I am playing Russian roulette and chancing a choking accident. They aren't capsules either, just dense pills so good luck getting it stuck in your throat. For this reason, I'm going to switch to powder instead.

works, but is a choking hazard
Product seemed to work by increasing N.O. pre-workout, verified by an incredible pump and vascularity. However, this is if you don't choke trying to swallow the giant, hard, dry, sharp tablet. Seriously, have someone on standby in case your immediate gag reflex causes a sheer panic-educed choking fit. Even when you are able to get it down, many times it scratches the throat enough to make you feel like it's stuck for a day or two. I don't think it would cost too much to capsule. I love NOW products, just this one is "hard to swallow".

Great vitamin/amino acid
I love this stuff and swear by it. I personally use this for anxiety and for interstitial cystitis! I’m not a medical professional so ask your dr! However just noting this stuff works for me! Love the brand. Pill size is big but doesn’t bother me at all!!!

【良い点】 ✔︎ 含有量が明確で選びやすい 1粒あたり1,000mgと配合量が分かりやすく、成分量を重視して選びたい人には判断しやすいと思います。 ✔︎ シンプルな原材料構成 L-アルギニン単体が中心で、余計な成分が少ない点に安心感があります。 日常的に取り入れる用途として管理しやすいと感じました。 【悪い点】 ✖︎ カプセルが大きめ 小指の先端ほどのサイズ感があり、人によっては飲みにくいかもしれません。 水の量を多めにすると飲みやすくなりました。 【総評】 成分量とシンプルさを重視する人向けのサプリメントだと思います。 カプセルサイズには好みが分かれそうですが、内容表示が分かりやすく、継続しやすい点は評価できます。

Its a good, essential protein and it is effective as the content described. My arms become more stronger after taking this. Size of the tablet is big and its taste is okay, not at all bad like many described. I am taking two to three tablet daily, mostly two. You need to take 10 to 14 days to see the effect. I am not sure about the sexual benefits, may be it has some impact. This tablets along with other protein supplements are pretty good for gym. I have read some bad review as well because there is always exceptions, you may fall under that category so always buy less or combined purchase and test them. I am satisfied with the product.
