What to know before you buy evening primrose oil

Capsules vs. liquid

Best evening primrose oil comes in capsules or in liquid form. If you intend to take your evening primrose oil orally, capsules are generally the best option because the oil is contained within the tablet so you don’t have to taste it. What’s more, it’s already portioned out into the correct dosage, so there’s no need to worry about accidentally taking too little or too much. 

Bottles of liquid evening primrose oil are a great option if you want to use evening primrose oil topically for issues such as acne or eczema or for its general moisturizing properties. You can use evening primrose oil on your skin undiluted, which is the best choice for medicinal uses. Alternatively, if you simply want a moisturizing boost, you can mix it with other oils and plant butter — such as shea butter or cocoa butter — in homemade skincare products. However, if your chosen liquid evening primrose oil is listed as therapeutic grade, it’s only suitable for topical use, while food-grade evening primrose oil can be used topically or taken orally. 

Strength and dosage 

If you buy evening primrose oil in capsules, it will list the strength per dose in milligrams. Most have strengths of between 500-and 1,500 milligrams per dose. It’s best to start at a dose of around 500 milligrams and work your way up if you don’t notice the effects. Some people safely take as much as 6,000 milligrams per day. 

Servings per pack

You might think that the number of servings per pack is the same as the number of capsules per pack, but this isn’t always the case. Also consider how many capsules a serving is, as this can sometimes be misleading. The listed dose can be made up of 2-4 capsules in some cases, so you get fewer servings than capsules. 

What to look for in quality evening primrose oil


Some capsules contain gelatin from animal sources, but this makes them unsuitable for vegetarians and vegans and potentially those who follow kosher or halal diets. However, you can find gelatin-free capsules, which get around this issue. 


If you prefer to stick to an organic diet, you can find plenty of evening primrose oil supplements that are USDA-certified organic. 

Good manufacturing practice certification

Supplements that are GMP-certified have been independently verified to meet certain manufacturing standards. This means you can be sure your supplements are produced in a sanitary way and that the laboratory and testing methods are up to scratch. 

How much you can expect to spend on evening primrose oil

You can spend anywhere between $10-$50 on evening primrose oil, depending on the package size, potency and overall quality.

Who shouldn’t take evening primrose oil? 

A. According to the Mayo Clinic, people with bleeding disorders or who are due to have surgery within the next two weeks shouldn’t take evening primrose oil. Its safety in children and pregnant people isn’t determined, so it’s best to avoid using it in these cases.
