Review: My HOLY GRAIL immunity supplement - This is my HOLY GRAIL of immunity supplements. I used to get sick a lot until I started taking this daily. I RARELY get sick now and when I do start to feel sick, I take 2 and it usually knocks it out in 1-2 days! I literally haven’t been sick longer than a day or two in the past 2 years. I should become a brand ambassador for this the way I constantly sell this stuff to people I know. It’s THAT amazing!!! Review: Good Quality NAC Supplement - I've been using this NAC supplement as part of my daily vitamin routine, and overall I've been happy with it. The capsules are easy to swallow and fit easily into my routine. When you first open the bottle, there is a mild sulfur-like odor. If you've taken NAC before, you'll know this is common with this type of supplement, so it wasn't a concern for me. The smell isn't overpowering, and I don't notice it once I take the capsule. The bottle arrived well sealed, and the capsules appear to be good quality. Since supplements affect everyone differently, I can't comment on specific health benefits, but I appreciate the quality and have had no problems taking them consistently. Overall, this is a good-quality NAC supplement that's easy to incorporate into a daily routine. If you're new to NAC, just be aware that the mild sulfur smell is normal. ## Features - Immune support – N-acetyl-L-cysteine, or NAC for short, is a novel nutrient that helps support the body’s healthy immune response, as well as bronchial and respiratory health. - Liver health – In addition to respiratory health, NAC supports liver health and function.
