Evening primrose oil for menopause has been used by many women. Mood swings, hot flushes, insomnia, night sweats, vaginal dryness, joint pain – can evening primrose oil help at least with some of those menopause symptoms? And what is the proper dosage of evening primrose oil for menopause symptoms?
Once a woman hasn’t had a period for 12 months, she is in menopause. But perimenopause symptoms can occur for years before periods end. They make life uncomfortable and stressful. Evening primrose oil is an alternative treatment to alleviate pain and discomfort during menopause. For women in menopause, evening primrose oil (EPO) is beneficial for the prevention of osteoporosis, when used together with calcium and fish oil.
Evening primrose oil for menopause – how exactly it works?
One of the most disturbing menopause symptoms is hot flashes. A disorder of thermoregulation causes them. Some women suffer from hot flashes for more than 10 years, while for others this symptom stops within 6 months. Many women that are taking evening primrose oil for menopause, notice that it helps to reduce severity of hot flashes.
• During the menopause ratio of female and male hormones distorts. That is why, to balance this ratio, doctors prescribe hormonal medication which, in turn, helps to reduce hot flashes severity. In addition, you will need to take medications to lower blood pressure, because often during menopause women are suffering from hypertension. Evening primrose oil is a natural, hormone-like supplement, that is widely used by many women to support hormonal therapy or as a stand-alone health supporting remedy.
• Your body needs a balance of nutrients and fatty acids to function properly. 25% percent of the evening primrose oil is made of fatty acids, the most important of which are gamma-linolenic acid or GLA and linoleic acid. Commercial preparations of evening primrose oil typically contain around 8 percent GLA and 65 – 80 percent linoleic acid . GLA, an omega-6 fatty acid, is called essential because you need to obtain it from food. Or from supplements like EPO.
• During menopause when the decrease in estrogen makes women prone to osteoporosis. Most postmenopausal women do not consume enough calcium and must use supplements to achieve the recommended amount. Evening primrose oil is one of the best supplements to combat this problem. A special combination of gamma-linolenic acid (GLA) and eicosapentaenoic acid (EPA) can increase calcium absorption from food, reduce calcium excretion from the body. Besides, these fatty acids can also lower blood pressure, prevent blood from clotting and reduce cholesterol levels.
Dosage of Evening Primrose Oil for Menopause
There are several factors to consider before buying evening primrose oil. And the percentage of GLA is one of the most important ones. The effectiveness of evening primrose oil will depend on how high this concentration is.
Pick one that is at least 8% GLA. 10% is an optimal concentration, while 12% is a high concentration of GLA.
Medical researchers of treatment of menopause symptoms recommend the following dosage:
3,000 mg containing 12% GLA (gamma-linolenic acid) daily for the first 12 weeks to rebuild your GLA stores and then take 1,000 mg as a maintenance dose. Most supplement labels recommend a maximum dosage of 4,000 mg/day.
Depending on the brand, this may result in taking 2 to 6 capsules per day:
1 capsule of Blackmores Evening Primrose Oil
The earliest period after benefit of the treatment can be assessed is 6 weeks. However, studies suggest, that evening primrose oil should be taken for 12 weeks minimum before it reduces menopause symptoms.
Clinical trials of evening primrose oil for menopause
While many women confirm that taking evening primrose oil helped them alleviate some of the menopausal symptoms, there is no one opinion in the scientific world, whether evening primrose oil really helps. Results of scientific studies vary.
For example, during the clinical trial  conducted in 2013, one group of women was consuming evening primrose oil, while another was taking a placebo. After 6 weeks scientists could note a significant reduction in the severity of the hot flashes. Frequency or duration of hot flashes also diminished, but at a much smaller level.
On the contrary, the study  reported no significant difference in hot flushes between evening primrose oil versus placebo.
Because evening primrose oil has been part of herbal medicine for hundreds of years, recommended by many practitioners, you could also give it a try. For example, a recent study revealed, that 500,000 Australian women use alternative menopause therapy. And evening primrose oil is among top alternative remedies. There is always a chance that you would have some positive benefit.
Side Effects of Evening Primrose Oil for Menopause
Evening Primrose Oil is well tolerated and safe if used as recommended. Allergic reactions are rare but possible. Sometimes women can suffer from an upset stomach while taking it. Therefore, always take evening primrose oil with food to avoid upset stomachs and other gastrointestinal side-effects.
It is also recommended to take it together with Vitamin E for better results.
Be aware, that using evening primrose oil in combination with other natural and herbal remedies can cause negative effects. For example, a study  warns, that taking natural energy supplement Korean Ginseng at the same time as evening primrose oil or an anti-clotting drug (like heparin or acetylsalicylic acid) could cause bleeding. EPO is not recommended for people with seizure or bleeding disorders.
How to store evening primrose oil
