Protect your body against oxidative stress

Fights inflammation and oxidative stress

NAC is the precursor to glutathione, a powerful antioxidant, which helps to scavenge free radicals and reactive oxygen species (ROS) that causes cell damage. It reduces oxidative stress and inflammation - especially beneficial if you have PCOS.* 

Improves insulin sensitivity

Insulin resistance is linked to the cardiometabolic and reproductive disorders in PCOS. NAC has insulin-sensitizing properties which improves your body’s insulin receptor activity, helping you lower insulin levels to keep PCOS symptoms at bay.

Supports and boosts fertility

Because of its potent antioxidant and insulin-sensitizing effects, NAC can help prevent endothelial damage, improve ovulation, and regulate menstrual cycles to support your overall reproductive health. NAC also has potential to improve pregnancy and live birth rates in women with PCOS.

Suggested Use:

Take 1 capsule, 1-2 times daily, between meals, or as directed by a physician.


Do not exceed recommended dose. Pregnant and nursing mothers, children under the age of 18, and individuals with a known medical condition or taking prescription medication should consult a physician before taking this or any dietary supplement.

Using NAC while going through IVF treatment

I've been taking this brand of NAC in preparation for an upcoming IVF cycle (Fertility treatment). I took these for my last cycle which resulted in my son so I'm convinced these, alongside many other supplements helped regulate my cycle and my body and get my eggs healthy again. The dosage is 600mg however for fertility treatment preparation I've been taking 2 pills (1200mg a day).

For fertility in general, NAC helps to lower insulin in your body and also thin cervical mucus to create an easier path for sperm to pass through and reach egg to fertilize it. NAC is also supposed to be great for woman with PCOS since it helps decrease testosterone in the body (regulate hormones). Lastly, it's also a good supplement for men who need to boost sperm quality/ count.

In conclusion, I'm no expert in supplements but I have been through 4 rounds of ivf so have a little knowledge in what works and doesn't to help egg quality. This is one supplement that I never forget to take and this brand has been good to me so far. No fillers, no weird odors or tastes. Highly recommend
