You should know how pervasive Prop 65 warnings are. The answer is almost certainly “none.” The threshold for what constitutes lead contamination under Prop 65 is so absurdly low that it’s useless, and the warning could even be referring to the silica packet included as a dessicant. Don’t eat (or snort) the silica packet or exceed reasonable doses and you’ll be fine. This is a quality product if you’re looking for a gentle form of vitamin C. **Q: How large are the capsules; are they easy to swallow?** A: I specifically ordered these because I just can't do the large chalky pills and these are great! I have no problem taking them; they are easy to swallow capsules. **Q: Are these tablets or capsules?** A: It says capsules on the bottle. **Q: What is the source of Bioflavonoids?** A: The bottle just says “citrus bioflavonoid complex”. I hope that helps ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product, good price *by M***K on April 29, 2026* Good product, good price Note:ANY calcium ascorbate product can cause a blood pressure drop in some people;this can be a good thing, but can also be an issue if it goes too low. ### ⭐⭐⭐⭐⭐ This stuff works!! *by C***V on April 25, 2026* I just happened to order this because my usual Vitamin C was out of stock.
