Media contact:Joy ScottScott Public RelationsJoy@ScottPublicRelations.com818-610-0270 **Q: Does this have 1000 mg per 1 pill or 2 pills?** A: 1000 per 1 pill **Q: Anyonce else have trouble swallowing this pill? I have cut it in half and it still is hard to swallow.** A: I agree this is difficult to swallow - and I don't want any applesauce or psychology suggestions. I have never had a problem swallowing pills but this one is a challenge and I always cut it in half. In the process, I assume some of the ingredient quantity is lost. **Q: Is quality of this product the same buying on amazon compared to buying from a healthcare provider?** A: You would have to get a lab to analyze! How could anyone tell just by looking at product or what the container says? Maybe it’s safer from health provider instead of third party ## Customer Reviews ### ⭐⭐⭐⭐⭐ American Made *by D***. on December 21, 2025* These vitamins offer a great combination to keep you healthy.
