Supporting Healthy Lipid

Supporting Healthy Lipid Balance

While the primary intervention for lowering cholesterol is still diet and lifestyle, a variety of dietary supplements have been shown to support healthy lipid balance.* Here are seven well-researched supplements to consider.

Healthy Lipid Balance

Beyond Red Yeast Rice Extract

Elevated serum cholesterol is an established factor influencing cardiovascular health. Total cholesterol, low-density lipoproteins (LDL), high-density lipoproteins (HDL), and triglycerides all influence cardiovascular health. Guidelines from the U.S. National Cholesterol Education Program identify LDL cholesterol levels as the most important of these factors, suggesting that an optimal level of LDL should be less than 100 mg/dL.

While the primary intervention for lowering cholesterol is still diet and lifestyle, a variety of dietary supplements have been shown to support healthy lipid balance.* Here are seven well-researched supplements to consider.


Red yeast rice extract is made by culturing rice with various strains of the yeast Monascus purpureus. This culturing process can produce a variety of compounds, including 14 active monacolins.

Numerous clinical trials have evaluated red yeast rice for lipid metabolism support. A 2015 meta-analysis reviewed 20 randomized, controlled trials of red yeast rice extract involving 6,663 participants. The amount of red yeast rice taken per day ranged from 1,200 to 4,800 mg, with levels of naturally occurring Monacolin K in the products ranging from 4.8 to 24 mg per day (averaging 10.8 mg). The analysis concluded that red yeast rice, when taken for four months, supported healthy LDL cholesterol levels.*

The amount of natural monacolins varies from source to source and product to product and cannot be standardized or quantified.  Many practitioners still like using red yeast rice, but it’s important to use a high quality product with consistent results. 


Niacin (nicotinic acid) was used as early as 1955 to support healthy cholesterol levels, but its mechanisms have only recently become understood. Niacin is thought to decrease mobilization of triglycerides from fat stores and inhibit triglyceride synthesis. It’s also believed to influence HDL metabolism. These benefits have been demonstrated with daily intakes of 1,200 to 2,000 mg of nicotinic acid.*

However, many people don’t want to take niacin because of the flushing reaction that can occur when a large amount is ingested at once. Depending on the sensitivity of each individual, even doses as low at 50 mg may cause flushing. Sustained-release niacin ameliorates the flushing reaction, but has a higher risk of damaging the liver.  It’s also important to note that no-flush niacin (inositol hexaniacinate) has not been shown to have the same cardiovascular benefits as nicotinic acid.

Another key point is that although niacin/nicotinic acid supports healthy lipid metabolism, those benefits may not translate to reduced cardiovascular risk. Two large, randomized, controlled trials (AIM-HIGH and HPS2-THRIVE) found that niacin supported healthy HDL cholesterol levels but didn’t affect the risk of cardiovascular events. For all of these reasons,  its use has fallen out of favor since other alternatives are available.


Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These essential fatty acids boast many health supporting benefits, including their ability to modulate eicosanoid metabolism to support healthy inflammatory response.* However, when it comes to supporting healthy cholesterol levels, the data on fish oils aren’t as clear.

Studies consistently show that fish oils support healthy triglyceride levels but not overall cholesterol levels. Moreover, the amount of EPA and DHA correlates with the ability to support triglycerides. A 2009 meta-analysis of 47 studies reported that daily consumption of 3.25 grams of EPA or DHA supported healthy triglyceride levels but didn’t affect total or LDL cholesterol.


Plant sterols and stanols are naturally occurring compounds in fruits, vegetables, grains, and oils. They’re also now found in fortified margarine, cooking oils, orange juice, and other functional foods. Examples include beta-sitosterol, campesterol, and stigmasterol. Plant sterols are similar in molecular structure to cholesterol and compete for absorption from the digestive tract.

The current interest in plant sterols stems from epidemiological studies that suggest people who consume more dietary plant sterols have healthier cholesterol levels. In recent years, more than 200 clinical trials have lent credence to the ability of plant sterols to support healthy LDL levels.*

Most studies of plant sterols have evaluated an intake of 2 grams per day from functional foods. Meta-analyses of these studies suggest that this amount supports healthy LDL cholesterol levels.* Based on this evidence, the National Cholesterol Education Program recommends that people with elevated cholesterol consume at least 2 grams of sterols or stanols per day.  There are many high quality plant sterol supplements available.


Policosanol is an extract from Cuban sugarcane wax that contains octacosanol and other alcohols. Some dietary supplement companies source policosanol from rice or wheat germ, but most clinical trials have evaluated policosanol from sugarcane. In addition to its well-known ability to support healthy lipid levels, policosanol also supports healthy platelet function and blood pressure.*

Policosanol was recently evaluated in a 2018 meta-analysis of 22 clinical trials. The pooled results from 1,886 participants showed that policosanol supported healthy levels of total cholesterol, LDL cholesterol, and HDL cholesterol.*

In a 2005 meta-analysis, researchers asked whether policosanol or plant sterols had a more pronounced effect on lipid levels. The analysis included 23 studies on plant sterols and 29 studies on policosanol. The researchers concluded that both plant sterols and policosanol supported healthy lipid levels, but that policosanol had a stronger effect.*

Policosanol’s mechanism of action is not well defined, but it has a good safety profile. Long-term studies of more than three years suggest it’s safe to take policosanol in amounts up to 20 mg per day.  The research seems to suggest that policosanol is an effective addition to any cholesterol protocol.


Garlic (Allium sativum) has been shown in many studies to support cardiovascular health due to its antioxidant activity and ability to support healthy blood pressure, lipid levels, and platelet function.*

Not all clinical trials show that garlic supports healthy cholesterol levels, but the most comprehensive and recent meta-analysis suggests it does. This analysis was published in Nutrition Reviews in 2013 and concluded that garlic taken for two or more months supports healthy total cholesterol, LDL cholesterol, and HDL cholesterol.*  The analysis didn’t find that garlic affects triglyceride levels.

Most clinical trials use 500 to 1,500 mg of dried garlic powder, equating to about one to two cloves per day. Alliin is the most abundant organosulfur compound in garlic, and many dietary supplements are standardized for this compound. Given the immune supportive properties of garlic as well, it is a smart addition to any cardiovascular health protocol.


A relative newcomer to the field of cardiovascular support is bergamot extract. The bergamot is a citrus fruit native to southern Italy with traditional uses that include supporting immune response and cardiovascular function.  A 2019 research review study published in the English journal Integrative food, nutrition and metabolism (IFNM) concluded that standard bergamot polyphenolic fraction (BPF®) as well as its phytosomal formulation (BPF Phyto) are effective in supporting healthy cholesterol levels.  Many practitioners now include bergamot extract in healthy lipid balance protocols.


These supplements are just a few of the dietary compounds that may support healthy lipid balance and we need to acknowledge the power of synergy. Some combination supplement formulas have demonstrated a benefit for supporting healthy lipid metabolism in clinical trials.  Soluble fiber abundant in vegetables and grains, for example, binds to cholesterol in the digestive tract and supports healthy cholesterol levels. Foods, herbs, and dietary supplements (such as coenzyme Q10, astaxanthin, and vitamin E) that are rich in antioxidants work together to support healthy lipid metabolism.*

Supporting healthy lipid balance  with supplementation is one piece of the puzzle when it comes to cardiovascular health.* Choosing to use or recommend any of the supplements discussed above should be done in the context of the overall health, diet, and lifestyle of any given patient. Weigh the risks and benefits of each supplement, and always check for nutrient and drug interactions.
