The Short Answer
Squalene is a triterpene compound that serves as a cholesterol precursor and powerful antioxidant, naturally found in shark liver oil and olive oil. It enhances skin barrier function through ceramide synthesis and supports cardiovascular health by modulating cholesterol metabolism via the mevalonate pathway.

Origin & History
Squalene is a natural organic compound originally sourced from shark liver oil but now also extracted from olives and other plant sources for sustainability.
“Squalene has been used in traditional medicine, particularly in Japan, where it is believed to promote health and longevity.”Traditional Medicine
Scientific Research
Research supports squalene's role as an emollient and antioxidant, with studies indicating its efficacy in skin hydration and protection.
Preparation & Dosage
The recommended oral dosage is 500 mg to 1,000 mg per day. Consult a healthcare provider before use.
Nutritional Profile
How It Works
Mechanism of Action
Squalene functions as an intermediate in the cholesterol biosynthesis pathway, converting to squalene epoxide via squalene epoxidase enzyme. It enhances skin barrier function by promoting ceramide and cholesterol synthesis in keratinocytes. The compound also exhibits antioxidant properties by scavenging free radicals and reducing lipid peroxidation through its unsaturated carbon structure.
Clinical Evidence
Human studies on squalene supplementation are limited, with most research focusing on topical applications. A 12-week study of 30 participants showed 23% improvement in skin hydration with topical squalene application. Cardiovascular studies primarily involve observational data linking dietary squalene intake to improved lipid profiles. Most immune function research comes from in vitro and animal studies, with human clinical evidence remaining preliminary.
Safety & Interactions
Squalene is generally well-tolerated with minimal reported side effects when used topically or consumed in normal dietary amounts. Shark-derived squalene may pose sustainability concerns, making plant-based alternatives preferable. High-dose supplementation may theoretically interact with statin medications due to cholesterol pathway involvement. Pregnancy and breastfeeding safety data is limited, requiring medical consultation before use.

Frequently Asked Questions
What is the difference between shark and olive squalene?
Both shark liver and olive-derived squalene have identical molecular structures and biological activities. Olive squalene is considered more sustainable and ethical, while shark squalene historically provided higher concentrations but raises conservation concerns.
How much squalene should I take daily?
No standardized dosage exists for squalene supplements, as most research involves topical application. Dietary intake from natural sources typically ranges 30-400mg daily. Consult healthcare providers before supplementing, especially above normal dietary levels.
Can squalene help with acne and skin problems?
Squalene may benefit acne-prone skin by restoring natural sebum balance without clogging pores, as it mimics skin's natural oils. Its anti-inflammatory and barrier-repairing properties can help reduce irritation and improve overall skin texture.
Does squalene actually lower cholesterol levels?
Squalene's role in cholesterol metabolism is complex, as it serves as a cholesterol precursor rather than directly lowering levels. Some studies suggest it may help optimize cholesterol ratios, but evidence for significant cholesterol reduction remains limited.
Is squalene safe to use with other supplements?
Squalene generally has low interaction potential with most supplements due to its natural occurrence in the body. However, it may theoretically interact with high-dose vitamin E or other fat-soluble compounds, requiring spacing of administration times.
