hydrogenated Coconut Oil
Also known as: Hydrogenated coconut oil, Hardened coconut oil, Fully hydrogenated coconut oil, Partially hydrogenated coconut oil, Hydrogenated Coconut Oil
Overview
Hydrogenated coconut oil is a modified form of coconut oil, derived from the meat of mature coconuts (Cocos nucifera), that has undergone a chemical process called hydrogenation. This process involves adding hydrogen atoms to unsaturated fatty acids, converting them into saturated fats. This alteration increases the oil's melting point and enhances its stability and shelf-life, making it more solid at room temperature compared to native coconut oil. While native coconut oil is often discussed for its potential health effects, hydrogenated coconut oil is primarily used in food manufacturing for its textural properties and as a source of saturated fat. It is crucial to distinguish it from virgin or refined coconut oil due to its altered fatty acid profile, which may include trans fats if partially hydrogenated. Research predominantly focuses on native coconut oil, with limited direct data available on the specific health impacts of hydrogenated coconut oil.
Benefits
Research on hydrogenated coconut oil specifically is very limited, with most studies focusing on native (non-hydrogenated) coconut oil. For native coconut oil, some modest benefits have been observed, though often with caveats. It has been associated with modest increases in HDL (''good'') cholesterol compared to other oils, but its effects on LDL (''bad'') cholesterol and total cholesterol are variable and can sometimes be unfavorable. While some studies suggest a statistically significant effect on body weight and BMI, these effects are generally considered clinically negligible, meaning they are too small to be meaningful for weight loss or waist circumference reduction. There are also limited case reports and studies suggesting potential glucose-lowering effects of native coconut oil, possibly due to phenolic compounds and medium-chain fatty acids, but this evidence is inconsistent and sparse. No robust evidence supports unique health benefits of hydrogenated coconut oil; in fact, its altered composition, potentially including trans fats, raises concerns about its impact on cardiovascular health.
How it works
The mechanism of action for coconut oil, in general, is primarily attributed to its medium-chain triglycerides (MCTs), particularly lauric acid. Unlike long-chain fats, MCTs are metabolized differently; they are rapidly absorbed and transported directly to the liver, where they can be quickly converted into energy or ketones, potentially increasing energy expenditure. This unique metabolic pathway may also influence lipid metabolism enzymes and pathways related to HDL and LDL cholesterol. However, the hydrogenation process significantly alters the fatty acid profile of coconut oil by increasing saturation and potentially reducing the proportion of beneficial MCTs. This alteration can change how the oil is digested and absorbed, and consequently, its metabolic effects within the body. Specific data on how hydrogenation impacts the bioavailability and metabolic pathways of coconut oil are largely lacking.
Side effects
Hydrogenated coconut oil, like other hydrogenated fats, is primarily a concern due to its high saturated fat content and the potential presence of trans fats if partially hydrogenated. Increased intake of saturated fats is generally associated with elevated LDL (''bad'') cholesterol levels, which is a known risk factor for cardiovascular disease. Partial hydrogenation specifically introduces trans fats, which have well-established adverse effects on cardiovascular health, including increasing LDL cholesterol and decreasing HDL (''good'') cholesterol. While no specific side effects have been reported for hydrogenated coconut oil as a direct supplement, its consumption as part of the diet contributes to overall saturated and potentially trans fat intake, thereby increasing cardiovascular risk. Individuals with pre-existing cardiovascular disease, diabetes, or those at high risk for these conditions are advised to limit their intake of saturated and trans fats, including hydrogenated oils. There are no documented drug interactions specific to hydrogenated coconut oil, but caution is generally advised for populations vulnerable to cardiovascular issues.
Dosage
There are no established dosing guidelines for hydrogenated coconut oil when considered as a supplement. Its intake typically occurs indirectly through its presence in various processed food products, where it is used for texture and shelf-life enhancement. For native (non-hydrogenated) coconut oil, studies have explored doses ranging from 10 to 30 mL per day. However, due to the significant alteration in fatty acid composition and physical properties caused by hydrogenation, these dosages and their associated effects cannot be directly extrapolated to hydrogenated coconut oil. Given the concerns regarding its saturated fat content and potential for trans fats, there is no recommended supplemental dosage, and its consumption should be limited as part of a healthy diet.
FAQs
Is hydrogenated coconut oil healthier than native coconut oil?
No, hydrogenated coconut oil is generally considered less healthy than native coconut oil. The hydrogenation process increases its saturated fat content and can introduce harmful trans fats, both of which are detrimental to cardiovascular health.
Does hydrogenated coconut oil aid weight loss?
Current evidence on native coconut oil shows minimal to no clinically meaningful effect on weight loss. Hydrogenated forms have not been specifically studied for weight management, and their altered fat profile suggests they are unlikely to offer benefits.
Is hydrogenated coconut oil safe for diabetics?
While native coconut oil may modestly affect glucose metabolism, saturated and trans fats, which are prevalent in hydrogenated coconut oil, are generally discouraged in diabetes management due to their negative impact on cardiovascular health.
Should hydrogenated coconut oil replace other cooking oils?
No, oils rich in unsaturated fats, such as olive oil or canola oil, are preferred for cardiovascular health over saturated or hydrogenated fats. Hydrogenated coconut oil should not be used as a primary cooking oil.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC9429773/ – This systematic review and meta-analysis of randomized controlled trials investigated the effects of coconut oil. It found that coconut oil increased HDL-C compared to other oils but showed no significant changes in weight or waist circumference. The study noted heterogeneity and confounding co-interventions as limitations, but its meta-analytic methods were robust.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC12142848/ – This systematic review and dose-response meta-analysis examined the effects of coconut oil on weight and BMI. It concluded that while there were statistically significant effects, they were clinically trivial. The study highlighted small sample sizes, short durations, and heterogeneity as limitations, providing moderate certainty for weight/BMI outcomes.

It concluded that the effects on lipids were mostly trivial or unfavorable and often did not meet thresholds for clinical relevance. The review was transparent but preliminary, aligning with broader literature findings.
- https://onlinelibrary.wiley.com/doi/10.1155/2020/8841781 – This case report and literature review described a single diabetic patient who experienced hypoglycemia after coconut oil supplementation. It suggested potential glucose-lowering effects but noted the limited generalizability due to being a single case study, thus providing a low level of evidence for broader conclusions.
