Which is better for cholesterol, fish oil or garlic?

Fish Oil vs. Garlic: What’s Better for Cholesterol?

When it comes to managing cholesterol, many people turn to natural supplements—and two of the most popular options are fish oil and garlic. But which one actually works better? According to research, the answer depends on which part of your lipid profile you’re trying to improve.

Garlic has shown promising results in lowering overall cholesterol levels. Studies reveal that garlic supplementation significantly reduces both total cholesterol and LDL-C—the so-called "bad" cholesterol linked to heart disease. This makes garlic a solid choice for those looking to improve their overall cholesterol numbers, especially if they’re dealing with high levels.

On the other hand, fish oil doesn’t lower LDL cholesterol—in fact, some studies show it may slightly increase it. However, its strength lies elsewhere. Fish oil is highly effective at reducing triacylglycerol concentrations (also known as triglycerides), a type of fat in the blood that, when elevated, raises the risk of heart disease. So while it may not help your LDL, it can significantly improve another critical marker of cardiovascular health.

So, which is better? It’s not a one-size-fits-all answer. If your main concern is high total or LDL cholesterol, garlic may be more beneficial. But if your triglycerides are the issue, then fish oil is likely the stronger option. In some cases, combining both might offer a more balanced approach, addressing multiple aspects of lipid health.

As always, it's wise to consult with a healthcare provider before starting any supplement regimen—especially if you're on medication or managing a health condition. Both garlic and fish oil have their place, but the best choice depends on your individual needs.
