Pure L-Arginine Powder, 10.6 oz (300 g)

I started using Doctor's Best's Pure L-Arginine powder and generally had positive experiences with the product. It is an effective option especially for those who want to increase their sports performance. Here are the details about the product: 1. **Increased Performance:** When I used this L-arginine powder before training, I felt a significant increase in my endurance. It allowed me to recover faster between sets and I felt more energy during training. The "Pump" effect was also quite satisfactory. 2. **Solubility:** The powder is very easy to mix with water or fruit juice. It dissolves quickly and does not clump. This provides a great advantage in terms of use. 3. **Price-Performance Ratio:** The 300-gram package is sufficient for long-term use. Since its price is also affordable, I think it is a good option when compared to similar products. 4. **Taste:** Although it may seem a little strange at first because it is unflavored, it can be sweetened by mixing it with other drinks. This creates the opportunity to try different drink combinations. 5. **No Side Effects:** I did not experience any side effects during my use. There was no stomach upset or other adverse events, which made it more comfortable to use. In conclusion, Doctor's Best Pure L-Arginine powder is an effective product for those who want to increase their sports performance and support their general energy levels. I definitely recommend it with its easy solubility, affordable price and positive effects. It is a good option for both pre-workout and daily energy support.

Twice a day, especially half an hour before a workout, definitely increases energy levels and blood flow into the muscles, personally for me. It smells and tastes a bit funny, but it’s hardly noticeable if mixing with protein powders, juice or coconut water.

It was a very good product and I received it quickly. Thank you to the iherb team.

L-Arginine supplies an amino acid vital in the synthesis of nitric oxide, which is an essential compound that helps blood circulation. Arginine-derived nitric oxide benefits wound healing and overall circulation, and has been shown to help increase mental acuity, immune function, and memory. Research suggests that L-Arginine supplementation helps increase muscle mass and may also positively be beneficial in improving endurance as it is a precursor to creatine, which helps supply energy to all cells of the body.

I’m very satisfied with this L-Arginine powder. The quality is excellent, and it mixes well with water or juice. The taste is neutral, which makes it easy to take every day. I also like that the container size is generous and lasts a long time. Overall, this is a great product for anyone looking for a clean, simple supplement. I would definitely purchase it again and recommend it to others.

It is said that arginine needs to be taken at a dose of 2000 to 4000 mg per day to be effective. One scoop contains 5000 mg, so you can take the appropriate amount. It doesn't taste good, but I mix it with other flavored supplements so it's not a problem. This is great quality ingredient, a lot of people recommend l arginine for the benefits for health, am using it for the first time, size is good so far they are no visible result.

L-arginine is a high-quality supplement with a single ingredient. While it may have a slightly tart taste when consumed on its own, it becomes more palatable when mixed with juice. This supplement is particularly beneficial for improving blood flow and can be a valuable addition to your training or workout regimen. The recommended dosage is convenient and easy to follow. L-arginine not only supports fitness goals but also enhances erectile function.

Great supplement! I'm very happy with the quality of this product, its package size as well as its composition. I was looking for l-lysine + l-arginine + l-ornithine + l-glutamine Complex, but didn't find anything. Very happy with the benefits of deciding to buy every ingredient separately. Great control over dosage than you will ever find in a complex or protein containing diet! And the price is the best benefit!

I’ve been using Doctor's Best Pure L-Arginine Powder for a few weeks now, and I’m very satisfied with the results. It’s a clean, pure form of L-Arginine, with no fillers or additives, which makes it easy to trust and incorporate into my supplement routine. I take it before workouts, and I’ve noticed a boost in endurance and better blood flow, especially during cardio sessions. It also seems to help with muscle recovery and overall energy levels. The powder dissolves well in water and has a neutral taste, which is a big plus. The packaging is secure and the scoop makes dosing easy. If you're looking for a reliable L-Arginine supplement for heart health, circulation, or athletic performance, this is a great choice!

I’ve been using Doctor’s Best Pure L-Arginine Powder for several weeks now, and I’m genuinely impressed. It mixes easily in water or juice, doesn’t have a strong unpleasant taste, and doesn’t upset my stomach. I usually take about 1 teaspoon (≈ 3 g) before workouts or on empty stomach in the morning, and I have noticed better blood flow, more endurance, and a slight pump during training. On non-training days I use a smaller dose, and I feel steady energy without crashes. The formula is simple and clean — no unnecessary fillers, artificial colors or flavors. For the price, it offers excellent value per gram, especially in the 300 g size.
