How effective is it?

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

The effectiveness ratings for FLAXSEED are as follows:

Possibly effective for...

Lowering hemoglobin A1c, a measure of average blood sugar level over three months, in people with type 2 diabetes. However, flaxseed doesn’t seem to lower fasting blood sugar, insulin levels, or blood fats in these people.
Lowering cholesterol levels in people with high cholesterol. Various flaxseed preparations - including ground flaxseed, partially defatted flaxseed, and flaxseed bread and muffins - seem to significantly reduce total cholesterol and the “bad cholesterol,” low-density lipoprotein (LDL) cholesterol, in people with normal cholesterol levels and in men and pre-menopausal women with high cholesterol. But flaxseed doesn’t have much effect on “good cholesterol,” high-density lipoprotein (HDL) cholesterol. Most flaxseed preparations don’t affect triglyceride levels either, but unfortunately partially defatted flaxseed (flaxseed without as much alpha-linolenic acid content) can increase triglycerides by approximately 10%.
Improving kidney function in people with systemic lupus erythematosus (SLE).
Relieving mild menopausal symptoms. Taking flaxseed by mouth seems to improve mild menopausal symptoms. But dose is important. Taking 40 mg of flaxseed daily seems to reduce hot flashes and night sweats in women with mild symptoms, but a lower dose of 25 grams per day doesn’t seem to work.

Possibly ineffective for...

Weak bones (osteoporosis).

Insufficient evidence to rate effectiveness for...

Breast pain (mastalgia). In one study, eating a flaxseed muffin each day for 3 months significantly reduced breast pain associated with the start of the menstrual cycle. The muffins each contained 25 grams of flaxseed.
Constipation. Flaxseed is a good source of dietary fiber and this leads people to think that it would be a good laxative. But so far, there hasn’t been any research to test this assumption.
Prostate cancer. Early research suggests that taking flaxseed and following a low-fat diet can lower prostate-specific antigen (PSA), a marker for prostate cancer, in men who have a precancerous prostate condition. However, in men who have prostate cancer, adding flaxseed to the diet does not lower PSA, but it does seem to lower levels of the hormone testosterone and slow the rate at which cancer cells multiply. More studies are needed.
Cardiovascular disease.
Cancer of the colon or rectum.
Diverticulitis.
Irritable bowel syndrome (IBS).
Stomach upset.
Bladder inflammation.
Lung cancer.
Breast cancer.
Skin irritation.
Attention deficit-hyperactivity disorder (ADHD).
Other conditions.
