Metamucil is a bulk-forming fiber laxative made from psyllium. Psyllium is a fiber that comes from Plantago ovata seed husks. It absorbs liquid in the intestine and swells. This helps produce softer, bulkier stools that lead to improved bowel movements.
What Are Bulk-Forming Laxatives?
Psyllium has been used as a natural remedy for ages. Metamucil didn’t come on the scene until 1934. According to Metamucil’s website, the product contains 100 percent natural psyllium husk fiber. In addition to lowering cholesterol and promoting regularity, Metamucil is thought to help you feel fuller between meals and help maintain blood sugar levels.
Psyllium is a natural product. It may reduce total cholesterol and low density lipoprotein (LDL). LDL, also known as “bad” cholesterol, contributes to clogged arteries and may lead to stroke and heart attack.
Psyllium is believed to help absorb waste, bile acids, and cholesterol, which are removed from the body during bowel movements. This may be due to its ability to swell and form a thick gel.

According to a more recent study published in the
A 2011 study published in the British Journal of Nutrition also found a connection between psyllium and cholesterol. Researchers concluded that adding psyllium to a normal or high-fiber diet resulted in lower LDL and total cholesterol levels.
Metamucil is available in a variety of forms, including:
- powder
- wafer
- health bar
- capsule
Wafers and health bars are great sources of fiber, but they’re not recommended to lower cholesterol. According to Metamucil’s website, the following dosages are needed to reduce cholesterol:
| Type | Dosage |
|---|---|
| Smooth texture, sugar-free, orange, and berry burst powders | 3 level teaspoons three times per day |
| Smooth texture orange powder | 4 level teaspoons three times per day |
| Original texture unflavored powder | 3 level teaspoons three times per day |
| Capsules plus calcium | 5 capsules four times per day |
You should take each Metamucil dose with at least eight ounces of water and drink plenty of fluids throughout the day. Check with your doctor to confirm the proper dose for you.
Metamucil is well tolerated by most people. However, side effects may occur, such as:
- gas
- nausea
- stomach pain
- bloating
To decrease your risk of discomfort, start with a lower dose and increase it gradually.
There are also additional side effects and precautions to consider when using psyllium. Some people may experience mild allergic reactions, such as hives, swollen nasal passages, swollen eyelids, and asthma. Metamucil may also cause rare, severe allergic reactions, such as:
- flushing
- severe itching
- shortness of breath
- throat tightness
- chest tightness
- wheezing
- swelling
- loss of consciousness
You should not take Metamucil if you have:
- fecal impaction
- narrowing of the colon
- bowel obstruction
- spastic bowel
Metamucil may also lead to a drop in your blood pressure.
If you’re planning to have surgery, you should stop taking Metamucil two weeks before the surgery. This is to avoid a potentially dangerous drop in blood sugar.
Metamucil may also interact with the following drugs or impact their effectiveness or potency:
- lithium (Lithobid, Lithane)
- carbamazepine (Tegretol, Carbatrol, Equetro, Epitol)
- antidiabetes drugs
- drugs for high blood pressure
- warfarin (Coumadin, Jantoven)
- digoxin (Digox, Lanoxin)
- herbs and supplements that lower blood pressure
- herbs and supplements that lower blood sugar
- iron
Metamucil may be a natural alternative to cholesterol-lowering drugs. When combined with a healthy diet and exercise, it may help lower cholesterol on its own or increase the effectiveness of cholesterol-lowering drugs. Talk with your doctor about your options for lowering your cholesterol. They can help you determine if taking Metamucil is right for you.
