The Benefits of Omega-7 for Menopausal Women

What is Omega-7?

Omega-7 fatty acids are monounsaturated fats that are part of the natural structure of the skin and mucous membranes in the body. The most common types are palmitoleic acid and vaccenic acid. Unlike omega-3 and omega-6, omega-7 is not an essential fatty acid, which means they can be produced inside our bodies. On the other hand, we are not able to naturally synthesize omega-3, which we need to obtain through our diet.

How Omega-7 Works

Omega-7 acts as a mediator between the body's fat and muscle tissues. It suppresses the production of new fat molecules, particularly those that damage tissues and increase cardiovascular risk.

In general, omega-7 plays a role in the proper functioning of the heart, skin health, mucous membranes, and even the digestive system.

Omega-7 for Better Management of Menopausal Symptoms

During menopause, many women suffer from pain, itching, or burning sensations. This can have a significant impact on daily life.

A study conducted on 45 women over a three-month period demonstrated the benefits of omega-7 on vaginal dryness. An impressive 86% of those who suffered from vaginal dryness reported an improvement in their symptoms after consuming sea buckthorn oil, which is rich in omega-7. Additionally, 77% noticed reduced pain during intercourse, and 88% reported the disappearance of general discomfort by the end of the study.

What Are the Health Benefits of Omega-7?

Omega-7 fatty acids are crucial for the proper functioning of our bodies and have been shown to:

• Reduce the risk of heart disease
• Maintain skin and hair health
• Relieve dry eyes
• Ease vaginal dryness

What Foods Are Rich in Omega-7?

Unlike omega-3, omega-7 is not abundantly found in our diet. The main natural source is sea buckthorn berries. In addition to sea buckthorn, omega-7 can also be found in macadamia nuts and spirulina.

Spotlight on Sea Buckthorn Oil

Sea buckthorn oil contains several compounds that can be beneficial to human health, including:

• Fatty acids, including omega-6 and omega-7
• Vitamins, including vitamin C, vitamin A, and vitamin E
• Antioxidants, such as flavonoids and polyphenols

It is known to promote skin hydration, reduce inflammation, and support mucous membrane health, which is especially important for menopausal women. Studies have shown that sea buckthorn oil can accelerate cell regeneration and renewal and is often used in skincare products to address dryness.

Lastly, an animal study revealed that this oil had a beneficial effect on eczema-like rashes in mice. Researchers applied the oil to the skin of mice for 4 weeks and discovered that it could inhibit inflammation, thereby improving symptoms.
