Reviewed by: HU Medical Review Board | Last reviewed: November 2024 | Last updated: November 2024
Flaxseed and the flax plant have been used for thousands of years for health and industrial applications. Also known as linseed or Linum usitatissimum, flaxseed is often used as natural remedy and herbal treatment for many conditions, including constipation, high cholesterol, and diabetes.1
Flaxseed contains an omega-3 fatty acid called ALA. Omega-3 fatty acids are known for health benefits such as reducing heart disease. Flaxseed and omega-3 fatty acids are being studied for their possible benefit in a range of conditions, such as ulcers, psoriasis, glaucoma, Lyme disease, lupus, and migraines. However, to date, the research in migraines has shown no or little benefit for reducing the frequency or severity of migraine attacks.2
Flaxseed health benefits
Like all natural remedies, flaxseed contains a wide range of compounds that may be responsible for its health benefits. Three main ingredients in flaxseed that are believed to contribute to their helpful properties are:2,3
- Omega-3 essential fatty acids, the good fats help with brain function and may cut the risk of heart disease
- Lignans, chemicals found in plants that act as antioxidants and like estrogen to protect cells
- Fiber, the part of food the body doesn’t digest, which can help ease bowel movements
Formulations available
Flaxseed is available in several preparations, including:1
- Whole flax seed
- Ground flax seed
- Powder
- Tablets
- Oil (which is also available in capsules)
What are the possible side effects?
Flaxseed and flaxseed oil are considered generally safe when taken in limited amounts. Because of the fiber content, flaxseed may cause an increase in bowel movements, bloating, gas, or diarrhea. When using for constipation, flaxseed should be taken with plenty of water.1,4
These are not all the possible side effects of flaxseed. Talk to your doctor about what to expect when taking flaxseed. You also should call your doctor if you have any changes that concern you when taking flaxseed.
Other things to know
Raw or unripened flaxseeds are believed to be toxic and shouldn’t be eaten.
People who are pregnant, may become pregnant, or those who are breastfeeding should not take flaxseed. Because it can have mild effects similar to estrogen, some doctors believe it may be dangerous during pregnancy.
Before beginning treatment for migraine, tell your doctor about all your health conditions and any other drugs, vitamins, or supplements you are taking. This includes over-the-counter drugs.
