Below is general information about the safety of the known ingredients contained in the product Flax Oil Capsules. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in amounts typically found in foods (7141,7142,7144). There is insufficient reliable information available about the safety of alpha-linolenic acid when used in larger, medicinal amounts.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts typically found in foods (7141,7142,7145).
There is insufficient reliable information available about the safety of alpha-linolenic acid during pregnancy and lactation when used in larger, medicinal amounts; avoid using.
LIKELY SAFE ...when ground flaxseed is used orally and appropriately. Ground flaxseed has been safely used in numerous clinical trials in doses up to 30-60 grams daily for up to 1 year (6803,6808,8020,10952,10978,12908,12910) (16760,16761,16762,16765,16766,18224,21191,21194,21196,21198) (21199,21200,22176,22179,22180,22181,65866,66065) (101943,101949,101950).
POSSIBLY SAFE ...when flaxseed lignan extract or mucilage is used orally and appropriately. Some clinical research shows that a specific flaxseed lignan extract (Flax Essence, Jarrow Formulas) 600 mg daily can be used with apparent safety for up to 12 weeks (16768). Additional clinical research shows that other flaxseed lignin extracts can be used with apparent safety for up to 6 months (21193,21197,21200). In one clinical trial, flaxseed mucilage was used with apparent safety at a dose of up to 5120 mg daily for up to 12 weeks (108047)....when flaxseed is used topically in a warm poultice (101946).
POSSIBLY UNSAFE ...when raw or unripe flaxseed is used orally. Raw flaxseed contains potentially toxic cyanogenic glycosides (linustatin, neolinustatin, and linamarin); however, these glycosides have not been detected after flaxseed is baked (5899). Unripe flaxseeds are also thought to be poisonous when consumed due to cyanide content.
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Flaxseed can have mild estrogenic effects. Theoretically, this might adversely affect pregnancy (9592,12907); however, there is no reliable clinical evidence about the effects of flaxseed on pregnancy outcomes.
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in food amounts. Edible oils containing high amounts of oleic acid are commonly used in foods (26466,90681,94452,101821,101824,101828,101830,101838). There is insufficient reliable information available about the safety of oleic acid when used as medicine.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using in amounts greater than those commonly found in foods.
Below is general information about the interactions of the known ingredients contained in the product Flax Oil Capsules. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, antibiotics might interfere with the metabolism of flaxseed constituents, which could potentially alter the effects of flaxseed.
Details
Some potential benefits of flaxseed are thought to be due to its lignan content. Secoisolariciresinol diglucoside (SDG), a major lignan precursor, is found in high concentrations in flaxseed. SDG is converted by bacteria in the colon to the lignans enterolactone and enterodiol (5897,8022,8023,9592). Antibiotics alter the flora of the colon, which could theoretically alter the metabolism of flaxseed.

Theoretically, using flaxseed in combination with anticoagulant or antiplatelet drugs might have additive effects and increase the risk of bleeding.
Details
|
Theoretically, flaxseed might have additive effects when used with antidiabetes drugs and increase the risk for hypoglycemia.
Details
|
Theoretically, flaxseed might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
Details
|
Theoretically, taking flaxseed might decrease the effects of estrogens.
Details
Flaxseed contains lignans with mild estrogenic and possible antiestrogenic effects. The lignans seem to compete with circulating endogenous estrogen and might reduce estrogen binding to estrogen receptors, resulting in an anti-estrogen effect (8868,9593). It is unclear if this effect transfers to exogenously administered estrogens.
|
Theoretically, oleic acid might increase the effects of antidiabetes drugs. Preliminary clinical research in patients with type 2 diabetes taking oral hypoglycemic drugs shows that eating a diet rich in oleic acid from olive oil decreases fasting blood glucose levels when compared to eating a diet rich in linoleic acid from sunflower oil (8132). It is unknown if taking oleic acid supplements would have this effect or if this change is clinically significant. Until more is known, use caution. Dose adjustment may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.

Below is general information about the adverse effects of the known ingredients contained in the product Flax Oil Capsules. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, alpha-linolenic acid from dietary sources is well tolerated when used in the diet as a replacement for other sources of fat, such as saturated fats.
Serious Adverse Effects (Rare):
Orally: There is some concern that high dietary intake of alpha-linolenic acid might increase the risk for prostate cancer, although research is conflicting.
Oncologic ...Epidemiologic research suggests that high dietary intake of alpha-linolenic acid might increase risk for prostate cancer (1337,2558,7823,7147,12978). Other research suggests high intake or serum levels of alpha-linolenic acid does not increase the overall risk of prostate cancer (12961,15736); however, it might increase the risk of advanced prostate cancer (12961). Association with prostate cancer appears to depend on the sources of alpha-linolenic acid. Dairy and meat sources has been positively associated with prostate cancer, whereas plant sources, such as flaxseed, don't seem to affect prostate cancer risk (12909). According to a clinical trial, intake of alpha-linolenic acid does not appear to increase levels of prostate specific antigen (PSA) (91402). Also, longer-chain omega-3 fatty acids in fish oils are associated with a decreased risk of total and advanced prostate cancer (12961).
Other ...Alpha-linolenic acid is a type of fat, containing 9 kilocalories/gram, and may result in weight gain if consumed in excess. Patients should be advised that it's best to substitute alpha-linolenic acid in the diet for other sources of fat, such as saturated fats.
General
...Orally, flaxseed is usually well-tolerated.
Most Common Adverse Effects:
Orally: Bloating, diarrhea, gastrointestinal complaints.
Serious Adverse Effects (Rare):
Orally: Severe allergic reactions such as and anaphylaxis.
Gastrointestinal
...Integrating flaxseed in the diet can cause digestive symptoms similar to other sources of dietary fiber including bloating, fullness, flatulence, abdominal pain, diarrhea, constipation, dyspepsia, and nausea (12910,16761,16765,21198,21200,22176,22179,65866,101943).
Higher doses are likely to cause more gastrointestinal side effects. Flaxseed can significantly increase the number of bowel movements and the risk for diarrhea (6803,8021,16765). Doses greater than 45 grams per day may not be tolerated for this reason (6802). Metallic aftertaste and bowel habit deterioration have also been reported in a clinical trial (21198).
There is some concern that taking large amounts of flaxseed could result in bowel obstruction due to the bulk forming laxative effects of flaxseed. Bowel obstruction occurred in one patient in a clinical trial (65866). However, this is not likely to occur if flaxseed is consumed with an adequate amount of fluids.
Immunologic ...Occasionally, allergic and anaphylactic reactions have been reported after ingestion of flaxseed (16761). Handling and processing flaxseed products might increase the risk of developing a positive antigen test to flaxseed and hypersensitivity (6809,12911,26471,26482).
Oncologic ...Flaxseed contains alpha-linolenic acid (ALA). High dietary intake of ALA has been associated with increased risk for prostate cancer (1337,2558,7823,7147,12978). However, ALA from plant sources, such as flaxseed, does not seem to increase this risk (12909).
Other ...Orally, partially defatted flaxseed, which is flaxseed with less alpha-linolenic acid, might increase triglyceride levels (6808). Raw or unripe flaxseed contains potentially toxic cyanogenic glycosides (linustatin, neolinustatin, and linamarin). These chemicals can increase blood levels and urinary excretion of thiocyanate in humans. However, these glycosides have not been detected after flaxseed is baked (5899).
General ...Orally, oleic acid generally well tolerated when used as part of oils and fats in the diet (26466,90681,94452,101821,101824,101828,101830,101838). Temporary burning in the mouth or throat has occurred in some patients (101848).
Gastrointestinal ...Orally, oleic acid has caused temporary burning in the mouth or throat in some patients in one clinical study (101848).
