Great VitC

This is one of the best quality vitamin C products I just discovered in iHerb! What's best about it is it has already vits D3 & zinc combined to it. This is my 2nd purchase (bought the biggest bottle) as the 1st one was a trial purchase.😅 The size of the capsule is a bit big but easy to swallow and accordingly, rapid dissolving. I presume the ingredients are great as it gives me & my family protection from common flu.

⭐️⭐️⭐️⭐️⭐️ High-Quality Immune Support – Clean and Effective Formula I’ve been using NutriBiotic Immunity Vitamin C + D3 & Zinc (100 capsules) and it has quickly become a reliable part of my daily wellness routine. The ingredients are simple and clean: vitamin C (ascorbic acid), vitamin D3 (cholecalciferol), zinc (as zinc citrate), and rice flour in a vegan-friendly capsule, free from GMOs, soy, and artificial additives. Each capsule contains potent amounts: 500 mg vitamin C, 25 mcg (1000 IU) vitamin D3, and 10 mg zinc, delivering strong support in a small, easy-to-swallow capsule. The size is generous — 100 capsules per bottle, making it long-lasting, and the package is sturdy and well-sealed to protect freshness. The formula is gentle on the stomach, even when taken daily, and provides antioxidant support thanks to vitamin C. The capsules are smooth, taste neutral, and very convenient to incorporate into any daily routine. Overall, this is a high-quality, potent, and reliable immune supplement with excellent ingredients and packaging — perfect for anyone looking for clean, easy-to-use support for daily wellness.
