I'll keep buying - I've been taking this once or more a day for the last few months. Sometimes I have fresh out days where I just don't seem to be able to keep it together. Little things might cause a meltdown, or cause me to feel like I'm losing my ability to "keep my cool." Sarcosine seems to have helped reduce my bad days quite a bit. And when I do kind of lose it, it's easier to reel myself back in. I have also been better able to focus on what needs done and get it finished. Before taking sarcosine, I had A REALLY hard time staying on task. I constantly felt frazzled and overwhelmed. Now, it's like I'm more able to reason with myself, so to speak, when I start to get frustrated. I'm so glad I tried this! Also, this brand has been well-packaged and consistent. It is shipped with cotton in the bottle so the capsules aren't damaged and broken. I've never had a problem with my orders from this seller. Each bottle has arrived on time and as described. Review: Wow! - Wow, oh wow. What a result. I felt a difference in just two days. After I discovered that omega 3s worked wonders for me, I tried many different supplements to see if any of them would have an effect as large as omega 3s; that is, if anything could help me as drastically as ALA, DHA, and EPA did. The only supplement I have come across so far that has had an effect (perhaps even more of an effect) is sarcosine. Within two days, I had a ton more energy, was happier, and was just more present. I found that I didn’t get bogged down in my thoughts nearly as much and was much more focused on everything around me - everything in the present moment. Even though the serving size is 3 capsules, I ended up cutting it down to 2 because the effect was so substantial. I completely recommend everyone try this amino acid. It is surprisingly effective. I want to note that, after being surprised at how well sarcosine works, I started reading more about it online. I discovered a brand called “ProFrontal” that sells a sarcosine+NAC combination, and apparently a lot of people have had positive effects from this duo. For right now, though, I’m sticking with just sarcosine, and I’ll try adding NAC later. I really recommend trying out sarcosine. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KN9XLRH | | ASIN | B07KN9XLRH | | Brand Name | Relentless Improvement | | Customer Reviews | 4.5 4.5 out of 5 stars (78) | | Date First Available | August 26, 2019 | | Dosage Form | Capsule | | Is Discontinued By Manufacturer | No | | Item Dimensions | 2.5 x 2 x 2.5 inches | | Item Form | Capsule | | Item Weight | 0.11 Kilograms | | Manufacturer | Relentless Improvement | | Manufacturer | Relentless Improvement | | Manufacturer Part Number | koks-808 | | Number of Items | 1 | | Product Dimensions | 2.5 x 2 x 2.5 inches; 3.99 ounces | | UPC | 854463005627 | | Unit Count | 90.00 Count | ## Product Details - **Brand:** Relentless Improvement - **Dosage Form:** Capsule - **Item Form:** Capsule - **Item Weight:** 0.11 Kilograms - **Item dimensions L x W x H:** 2.5 x 2 x 2.5 inches - **Manufacturer:** Relentless Improvement - **Number of Items:** 1 - **UPC:** 854463005627 - **Unit Count:** 90.00 Count ## Images ![Sarcosine N-methylglycine - Image 1](https://m.media-amazon.com/images/I/51vkgd3jQ+L.jpg) ![Sarcosine N-methylglycine - Image 2](https://m.media-amazon.com/images/I/71jS6LEF6zL.jpg) ![Sarcosine N-methylglycine - Image 3](https://m.media-amazon.com/images/I/819Ux7YfnQL.jpg) ![Sarcosine N-methylglycine - Image 4](https://m.media-amazon.com/images/I/71RaG2Ud5dL.jpg) ## Questions & Answers **Q: Hello what color are the capsules supposed to be?
