Evening primrose oil is a popular natural supplement that is derived from the seeds of the evening primrose plant. It contains a high concentration of gamma-linolenic acid (GLA), which is an omega-6 fatty acid that is thought to have a number of health benefits.
Some people take evening primrose oil as a dietary supplement in the hope of improving various conditions such as eczema, breast pain, premenstrual syndrome, and menopause symptoms.

However, there has been some speculation that evening primrose oil may cause weight gain. In this article, we will explore the evidence for and against this claim.
First, it is important to note that there is no scientific evidence to suggest that evening primrose oil directly causes weight gain. In fact, some studies have found that GLA may have weight loss benefits.
For example, a 2016 study published in the journal Lipids in Health and Disease found that GLA supplementation led to a reduction in body weight, body mass index (BMI), and waist circumference in overweight and obese women.
Another study published in the Journal of Nutritional Biochemistry found that GLA supplementation reduced body fat and improved insulin sensitivity in mice.
That being said, some people have reported weight gain as a side effect of taking evening primrose oil. However, it is important to note that weight gain can be caused by a number of factors, including diet, exercise, stress, and hormonal changes.
Therefore, it is difficult to determine whether evening primrose oil is the cause of weight gain in these cases.
There are a few theories as to why some people may experience weight gain when taking evening primrose oil. One theory is that it may stimulate appetite. However, there is limited evidence to support this claim.
Another theory is that it may interfere with the metabolism of certain hormones, such as thyroid hormones, which can lead to weight gain.
However, this theory is also not well-supported by scientific evidence.
It is worth noting that some brands of evening primrose oil supplements may contain added ingredients that could contribute to weight gain.
For example, some supplements may contain fillers or other additives that are high in calories or have a high glycemic index, which could lead to increased hunger and weight gain. Therefore, it is important to choose a high-quality supplement that is free from unnecessary additives.
In conclusion, there is no direct evidence to suggest that evening primrose oil causes weight gain. While some people may experience weight gain as a side effect of taking the supplement, it is difficult to determine whether it is the cause of weight gain in these cases.
It is possible that certain brands of evening primrose oil supplements may contain added ingredients that could contribute to weight gain, so it is important to choose a high-quality supplement that is free from unnecessary additives.
Overall, if you are concerned about the possibility of weight gain when taking evening primrose oil, it is always best to speak to your healthcare provider before starting any new supplement regimen.
