Excellent!

If you want to buy vitamin C and have the benefit of vitamin C you need to buy a product like this with a C complex Which includes bioflavonoid complex besides the ascorbic acid that you find and all the other products, that’s my second bottle and I’m ordering the third

Inclusion of silicon dioxide and stearic acid

I was disappointed with this product due to the inclusion of silicon dioxide and stearic acid in its formulation. While I understand these are common additives, I have concerns about their safety. Silicon dioxide, though FDA-approved, has raised questions about its potential long-term effects, and I prefer not to consume products with such ingredients. Additionally, for the high price of this supplement, I expected a cleaner, more natural formulation. I will not be repurchasing and recommend the company consider revising their ingredients to meet higher health standards

High Quality Vitamin C – Excellent Whole Food Source

Verified purchase

I am really impressed with the quality of these Complex C tablets. The ingredient list is fantastic, especially since it uses whole food sources like organic oranges, which makes a big difference. The tablets are a manageable size and easy to incorporate into my daily routine. With a solid mg count per serving, it’s a great way to support my immunity, and I’ve found it to be very gentle on the stomach without any issues from acidity. The package arrived well sealed and the 180-tablet count is a great value. Highly recommend this for anyone looking for a high-quality, clean vitamin C supplement!
