4 PCOS Supplements to Lower Cholesterol

It’s not unusual for people with PCOS to have high cholesterol. Dyslipidemia (low HDL or “good” cholesterol, high LDL “bad” cholesterol and high triglycerides) have been shown to affect up to 70% of women with PCOS. The good news: cholesterol levels can be reversed with nutrition, exercise and lifestyle changes.

Over the past decade, emerging science has investigated how nutritional supplements used in the PCOS population can help lower cholesterol levels. Here are four of the most highly researched PCOS supplements shown to lower cholesterol

Fish Oil

Fish oil is one of the most effective ways to lower elevated triglycerides (the blood storage form of fat). High triglycerides can occur if you have high insulin levels.

Nutrition guidelines recommend we consume cold-water or fatty fish two times per week to reap the benefits of omega-3 fatty acids. Salmon, halibut, tuna, and trout are the best sources of omega-3s. Even if you eat these types of fish twice a week or more, you may consider taking a fish oil supplement to help lower elevated triglycerides. Most people need between 1 and 4 grams daily, depending on how high their triglyceride levels are.



NAC is a powerful antioxidant that has been compared with metformin in women with PCOS. In the studies, not only did NAC improve insulin levels on par with metformin, but this favorite PCOS supplement lowered cholesterol levels better than the common medication did, especially for total and LDL levels.

Berberine is an herbal supplement shown to be very effective to lower cholesterol levels in PCOS.

Berberine works by slowing the release of free fatty acids while boosting fat burning in the mitochondria to lower cholesterol levels. Berberine also inhibits the enzyme lipoprotein lipase which is responsible for producing cholesterol and triglycerides. Berberine has also been shown to promote cholesterol excretion from the liver to bile.

When compared with metformin in women with PCOS, berberine reduced total cholesterol, TG, and LDL significantly more than metformin did. Berberine also increased HDL (the good kind) significantly more than metformin.

In people with type 2 diabetes, berberine when combined with oral lipid lowering drugs was better than lipid lowering drugs alone in reducing total and LDL cholesterol and raising the level of HDL.


Resveratrol, an antioxidant found in the skin of grapes, berries, red wine and peanuts, has been known for anti-aging, anticancer, and cardioprotective properties.

Rich in polyphenols and antioxidants, resveratrol has been shown to have the potential to fight inflammation as well as lower cholesterol and insulin.

A review of 16 studies showed supplementing with resveratrol (> 500mg daily for 10 weeks or more) can significantly reduce triglycerides and increase HDL cholesterol.

Resveratrol has also been shown to help improve fertility and insulin in people with PCOS.

    I am a registered dietitian nutritionist and certified diabetes care and education specialist and work with a lot of patients with pre diabetes, diabetes and pcos.
    I was wondering if these supplements are only prescribed for women with pcos can some be used for women with pre diabetes or men with diabetes or pre diabetes ?
