Doctor's Best NAC Detox Regulators is an NAC supplement with two added minerals, selenium (as Seleno Excell) and molybdenum. NAC, short for N-acetyl cysteine, is a form of the amino acid cysteine. Your body uses cysteine to make glutathione, an antioxidant found inside your cells, and selenium is part of the enzymes that work with glutathione. The formula is vegetarian, non-GMO, gluten free and soy free, according to Doctor's Best.

What is in it
NAC. The main ingredient. It has a natural sulfur smell, so an eggy smell from the bottle is normal.
Selenium. An essential trace mineral. Seleno Excell is a branded selenium yeast.
Molybdenum. Another essential trace mineral, needed in very small amounts by enzymes that process sulfur-containing amino acids.
How it differs from plain NAC. A plain NAC capsule has NAC only. This one adds the two minerals, so you need to count them if you take other supplements. Check the supplement facts panel on the bottle for the exact amount of each per capsule.
Who it suits
- Adults who want NAC with selenium and molybdenum in one capsule.
- People who are not already getting selenium from a multivitamin.
- Vegetarians.
Who should check first
- Already taking selenium: add up your totals. Australian supplement labels warn not to exceed 150 mcg of selenium a day from supplements, and the adult upper level from all sources is 400 mcg a day.
- Taking prescription medicine: check with your doctor or pharmacist, especially for nitroglycerin and blood thinners.
- Medical conditions: speak to your doctor first if you have asthma, stomach ulcers or a bleeding disorder.
- Pregnant or breastfeeding: check with your doctor first.
How to use it
Follow the directions on the label and do not take more than it says. If NAC upsets your stomach, take it with food. If you want NAC without the added minerals, compare it with Life Extension N-Acetyl-L-Cysteine 600 mg.
