Lorenzo's Oil Drug Interactions, Uses, Effectiveness, Safety & More

Lorenzo's Oil is not a traditional herb or plant tea. It is a carefully made mixture of two fats called glyceryl trioleate and glyceryl trierucate, usually combined in about a 4-to-1 ratio. These fats come from plant oils such as rapeseed (canola) and olive oil that have been refined and purified.

The oil was created in the 1980s by the parents of a boy named Lorenzo Odone, who had a rare genetic disease called adrenoleukodystrophy (ALD). Their story was made into a well-known movie, which is how the oil got its name.

Lorenzo's Oil is taken by mouth as a liquid oil and is used as part of a medical plan for ALD and a related condition called adrenomyeloneuropathy (AMN). It is not sold as a general-purpose wellness supplement.

In ALD, the body struggles to clear very long-chain fatty acids, which then build up to harmful levels. The fats in Lorenzo's Oil—oleic acid and erucic acid—are thought to compete with the body's own enzyme system that makes these very long-chain fats.

By providing large amounts of shorter fats, the oil appears to slow down the body's production of the harmful very long-chain fatty acids. This helps bring blood levels down. A low-fat diet is used alongside the oil to limit how much VLCFA comes in from food.

Much of the detailed understanding of how it works comes from laboratory and clinical research in people with ALD. Importantly, lowering the fatty acids in the blood does not always translate into protecting nerve tissue that is already affected.

Lorenzo's Oil should only be used under the care of a doctor who specializes in ALD or metabolic disease. It is part of a structured treatment plan that usually includes a strict low-fat diet and regular blood monitoring.

People taking it need ongoing checks of blood counts and other lab values, because the oil can affect certain blood cells. It is not appropriate to use this product on your own as a general health supplement.

Pregnancy: Safety during pregnancy has not been established. Avoid unless a specialist specifically advises otherwise. Breastfeeding: There is not enough information to call it safe, so it is best avoided while nursing unless your doctor directs it. Always talk with your pharmacist or doctor before use.

The most commonly reported concern with Lorenzo's Oil is a drop in certain blood cells, particularly platelets (which help blood clot) and sometimes white blood cells. This is why regular blood tests are part of treatment.

Other possible effects include stomach upset, nausea, and changes in liver function tests. Because the treatment also involves a very low-fat diet, careful nutrition planning is needed to avoid missing important nutrients.

Report any unusual bruising, bleeding, infections, or other new symptoms to your healthcare team right away.

There is no standard over-the-counter dose for Lorenzo's Oil. When used medically, the amount is calculated by a specialist based on the person's body and is adjusted using blood tests and a carefully controlled low-fat diet.

Because dosing must be individualized and monitored, you should not try to dose this product yourself. Follow the exact instructions of the treating physician and check with your pharmacist about how to take it. Do not use it as a casual supplement.
