Doubtful ingredients

It is good size. Suitable 500 mg doze. There is no problem with this. But I cannot understand presence of other ingredients: methylcellulose, magnesium silicate, stearate, PEG, silicone dioxide, polyvinyl alcohol, titanium dioxide… some of these ingredients for smoothing and make it hydrophobic but it causes digestive issues.That’s my fault that I didn’t check compound. But anyway, due to the ingredients I don’t recommend it.

Excellent!

The bottle I got definitely says chewable. There seems to be some disagreement about that. And to me at least they do taste bitter. I tried to chew them but they actually made me gag. I thought about trying to just swallow them. But I'm not comfortable swallowing pills and that was the whole point of chewable. I also have acid reflux and thought they might upset my stomach if I swallowed them. I have bought this brands other regular vitamins in the past with no problem. But sadly, I ended up throwing these away.

24 August 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!

Vitamin C Supplement

The quality of this Vitamin C supplement is impressive. Vitamin C is essential for immune support, skin health, and antioxidant protection, and this supplement delivers on those fronts. Since I started taking it, I’ve noticed that my immune system seems stronger I haven’t caught the seasonal cold that often hits me around this time of year. My skin also looks brighter and more even-toned, which I attribute to the vitamin’s role in collagen production and fighting free radicals.
