Thank you hayley3--
The buffered Thorne should be great quality I like that it lists Other Ingredients: None!
I also love HealthForce Nutritionals and believe them to be quality too. I prefer food based or whole food supplements when possible. Only not sure if since Truly Natural Vitamin C is 100% cherry sourced if it would be OK for the Candida Protocol I am preparing to do. I took The Synergy Company, Pure Radiance C (wildcrafted camu camu, and organic amla, acerola, blueberries, raspberries, lemons, cranberries, cherries, rose hips, and sprouts — 100% natural sources of vitamin C) and it did not agree with me and the similar Nature's Way Alive C (100% organic fruit sources: acerola, goji, amla (amalaki) and kiwi) did not agree with me either. I am nightshade sensitive so maybe it was the camu camu in the Radiance C product and the goji in the Alive C product. Not sure.
Any way thank you for the suggestions!!
