Perfect Dosage with Long-Lasting Vitamin C Support

iHerb customer August 23, 2024

I really appreciate this 21st Century Vitamin C supplement! The 500mg dosage is just right—not too high, making it easy on the stomach, while still providing the immune support I need. The prolonged release feature is a big plus, ensuring that I get a steady supply of vitamin C throughout the day. It's a great option for those looking for consistent and manageable vitamin C intake. Highly recommend for anyone wanting to maintain their health without overdoing it!

Just started taking this supplement. It's easy to swallow, and I've noticed no digestive issues. I take it with my morning smoothie. Comes in an easy to open container.

iHerb Customer April 23, 2024

This is the usual form of vitamin C. It's cost-effective and gentle on the stomach. Pills are easy to swallow and have a long release, making them a great value for their price. I believe there is no distinction between the multiple vitamin C options available, so it's better to choose the least expensive option available. The quality is acceptable.

I recently started taking vitamin C pills, and I'm very pleased with the results! These supplements have become an essential part of my daily routine. I've noticed an improvement in my immune health, especially during the cold season. The pills are easy to swallow, and I appreciate that they're made with high-quality ingredients. Since incorporating them into my regimen, I feel more energetic and resilient. If you're looking for a reliable way to boost your vitamin C intake and support your overall health, I highly recommend these vitamin C pills!

unsure about the prolonged release but the price premium was so insignificant so I gave it a try. Probs would return to just a regular vitamin c product.
