Not bad but the seal needs fixing

this is my first time ordering from iherb. tbh it was quite a good experience overall. —— the packaging was great, safe and protective. but the container’s seal was pain, because there is still some residue of plastic around the edge, but i guess it wouldn’t affect the inner contents. but i really hope they can change the seal to an easy-open one. —— the pills don’t have strong smell or taste, which is good. suitable size, adults can easily handle that. i just took one, so not much of an effect im experiencing, at least for now.

Great immune support

I’ve been taking this for a few weeks now and I really like it. The combination of vitamin C, D, zinc and selenium is exactly what I was looking for. I feel like it’s helping support my immune system, especially during busy or stressful periods. Capsules are easy to take and the quality seems very good. I’ll definitely keep using it.

Complete Daily Immunity Support in One Bottle

This 4-in-one supplement combines Vitamin C, D3, Zinc, and Selenium with great quality and clean ingredient sourcing. I noticed a real benefit in stronger immunity and fewer cold-like symptom during stressful weeks. The capsules have no unpleasant taste, making them easy to take daily. The package of 180 vegi caps is practical and lasts a long time. Overall, it’s a convenient and effective formula for anyone wanting simple, all-in-one daily health support.

Perfect daily protection — Great ingredients! ⭐⭐⭐⭐⭐

I’ve added Immune Complex 4 to my daily routine and it’s very convenient. It contains a solid blend of Vitamin C, Vitamin D, Zinc, and Selenium. I find it’s best to take this in the morning, either with a meal or right after eating, to ensure the fat-soluble vitamins (like Vitamin D) are absorbed properly and to stay easy on the stomach. It’s a great 4-in-1 formula for anyone looking to simplify their supplements. The capsules are standard size and easy to swallow. Please click YES if you found this tip helpful! 🙏

Previously "Immune 4" & "Immune 4 Complex"

Quality: Broad-spectrum immune formula with Vitamin C, D, Zinc, and Selenium. Size: Large capsule; easy to swallow with enough water. Dosage: Once daily, but increased to 2–3× daily when sick or exposed to illness. Benefit: Supports immune defense and recovery. Package: Durable bottle with secure sealing. Taste: No taste or smell. Other Aspects: This is one of the supplements I rely on most when I feel a cold coming or when surrounded by sick children at work. It absolutely works as advertised and is a staple for my immune health. If I do have a cold, it never got to a point of a fever which I believe is thanks to this product.
