What Does Hemp Seed Oil Actually Do for Your Body?

Posted by Holy Trinity Mind Body Soul on 9th Jul 2026

Quick Answer: Hemp seed oil provides the body with essential omega 3 and omega 6 fatty acids it cannot produce itself, along with vitamin E and trace minerals including magnesium, phosphorus and potassium. It is a plant based food supplement regulated in Australia by FSANZ, suitable for people seeking a vegan alternative to fish oil. It is THC free, non GMO and does not require a prescription.

Hemp seed oil has become one of the most talked about natural supplements in Australia over the past few years. You will find it in health food stores, online wellness shops, and increasingly in everyday kitchens. But beyond the buzz, people want a straight answer: what does hemp seed oil actually do for your body?

Here is an honest, clear breakdown of what the research and nutrition science tells us. If you are new to hemp seed oil, we also recommend reading our beginner's guide to hemp seed oil in Australia for a broader overview.

It Gives Your Body Essential Fatty Acids It Cannot Make Itself

The most well understood nutritional role of hemp seed oil is its fatty acid content. Hemp seed oil is naturally rich in omega 3 and omega 6 essential fatty acids, including gamma linolenic acid (GLA). The word "essential" in nutrition has a specific meaning: these are fatty acids the human body cannot produce on its own, so they must come from the food and supplements you consume.

Essential fatty acids play important roles in normal body functions. They are key components of cell membranes and are involved in processes related to inflammation responses and cardiovascular function. Hemp seed oil contains these in an approximately 3:1 ratio of omega 6 to omega 3, which many nutritionists consider close to optimal for human health.

It Provides Vitamin E and Trace Minerals

Beyond fatty acids, hemp seed oil also contains vitamin E, a fat soluble antioxidant that plays a role in protecting cells from oxidative damage. Hemp seeds, from which the oil is cold pressed, also naturally contain B group vitamins, phosphorus, potassium, magnesium and iron.

These nutrients contribute to hemp seed oil's reputation as a nutritionally dense food supplement, rather than simply a source of fats.

What the Research Is Still Exploring

It is worth being honest about what is still being studied. Much of the popular information about hemp seed oil online goes further than the current evidence supports. While early research into GLA and omega 3 fatty acids is promising in a number of areas, it is important to understand that hemp seed oil is regulated in Australia as a food supplement, not a therapeutic product. It is not approved by the Therapeutic Goods Administration for the treatment or prevention of any specific health condition.

What this means in practice is that hemp seed oil is a nutritionally valuable daily supplement for people who want to increase their intake of plant based essential fatty acids, particularly as an alternative to fish oil for those following a vegan or plant based lifestyle.

Is Hemp Seed Oil Right for You?

Hemp seed oil suits people who are looking to add a plant based omega 3 and omega 6 supplement to their daily routine. It is THC free, non GMO and vegan, which makes it accessible to a wide range of people.

If you are currently taking medication, particularly blood thinning or blood pressure medication, speak with your healthcare professional before adding any new supplement to your routine.

Frequently Asked Questions About Hemp Seed Oil

Is hemp seed oil legal in Australia?

Yes. Hemp seed oil is completely legal in Australia. Hemp seeds were approved as a food ingredient by Food Standards Australia New Zealand (FSANZ) in November 2017. Hemp seed oil is sold as a food supplement and does not require a prescription.

Is hemp seed oil the same as CBD oil?

No. Hemp seed oil is cold pressed from hemp seeds and contains negligible levels of CBD and THC. CBD oil is extracted from the flowers and leaves of the hemp plant and contains meaningful concentrations of cannabidiol. In Australia, CBD oil requires a prescription. Hemp seed oil does not.

Does hemp seed oil contain THC?

Hemp seed oil sold as food in Australia must contain no more than 10 parts per million of THC, an amount so negligible it has no physiological effect. Quality Australian hemp seed oils are tested to confirm they meet this standard and are labelled THC free.

How much hemp seed oil should I take per day?

Most hemp seed oil products suggest one to two teaspoons of liquid oil per day, or two to four capsules depending on the product strength. Always follow the directions on the label of the specific product you are using. If in doubt, consult your healthcare professional.

Can vegans take hemp seed oil?

Yes. Hemp seed oil is 100% plant based and suitable for vegans and vegetarians. It is one of the few plant based sources of both omega 3 and omega 6 essential fatty acids, making it a popular alternative to fish oil for people following a vegan lifestyle.

What is the difference between hemp seed oil liquid and capsules?

Both formats contain the same cold pressed hemp seed oil. The liquid oil is versatile and can be drizzled over food or added to smoothies. Capsules are convenient for daily use, have no flavour, and are easy to take on the go. Both formats are available in our Aussie Legends Hemp range.
