How do I take NAC?
The right amount is different for each person. Your practitioner sets the dose and schedule that fits you. Most people take NAC between meals with water.
What is NAC, simply put?
It's a ready-to-use form of cysteine. Your body uses cysteine to make glutathione. Glutathione is its own master antioxidant. Think of it as topping up your natural defenses.
Can my child take it?
Only with your practitioner's guidance. They can confirm the right fit and dose for a child. When in doubt, talk to them first.
Can I take it with my medication?
Check with your practitioner first. This matters most if you take nitroglycerin, blood thinners, or any prescription. We're glad to help you start that talk.
Why does it smell faintly like sulfur?
A faint sulfur smell is normal for NAC. It comes from the cysteine itself. It doesn't mean anything is wrong.
Should I take it with or without food?
Most people take NAC between meals with water. Your practitioner can set the timing that works for you.
