Arlene Semeco, MS, RD. wrote a great article on the benefits Psyllium on the Authority Nutrition website. We would like to share that article with you today. We do note the mention of Metamucil in the article. There are far better tasting, natural Pysillium products than Metamucil such as Organic NuSyllium.
Psyllium is a type of fiber commonly used as a gentle, bulk-forming laxative.
Being a soluble fiber, psyllium is able to pass through your digestive system without being completely broken down or absorbed.
Instead, it absorbs water and becomes a viscous compound that benefits constipation, diarrhea, blood sugar, blood pressure, cholesterol and weight loss.
This article tells you all you need to know about psyllium, including 7 ways it can benefit your health.
7 It Has Prebiotic Effects
Prebiotics are non-digestible compounds that nourish intestinal bacteria and help them grow. Psyllium is considered to have prebiotic effects (40, 41).
Although psyllium is somewhat resistant to fermentation, a small portion of psyllium fibers can be fermented by intestinal bacteria. This fermentation can produce short-chain fatty acids (SCFA), which have been linked to health benefits (3, 42, 43, 44).
One study showed that 10 grams twice a day for 12 months increased the production of the SCFA butyrate (45).
Also, because it ferments more slowly than other fibers, it doesn’t increase gas and digestive discomfort.
In fact, treatment with psyllium for four months helped reduce digestive symptoms by 69% in patients with ulcerative colitis (UC) (46).
Furthermore, a combination of psyllium and probiotics seems to be particularly effective at treating ulcerative colitis and Crohn’s disease (47, 48).
Bottom Line: Psyllium is considered a prebiotic fiber. It can promote short-chain fatty acid production and decrease digestive discomfort in patients with ulcerative colitis and Crohn’s disease.
6. It Seems to Be Good for Your Heart
Adding water-soluble fibers like psyllium to your diet might reduce blood triglycerides, blood pressure and the risk of heart disease (36, 37).
One study confirmed that 5 grams of psyllium three times daily for six weeks reduced triglycerides by 26%, compared to the placebo (19).
Moreover, in 40 patients with type 2 diabetes, triglyceride levels were significantly reduced after two months of treatment with psyllium fiber (36).
Furthermore, a diet with an additional 12 grams of fiber from psyllium supplementation reduced systolic blood pressure by 5.9 mmHg in 36 people with high blood pressure (38).
Lastly, another study in obese individuals showed that a 7-gram daily dose for 12 weeks led to a seven percent decrease in blood pressure in the first six weeks of treatment (39).
Bottom Line: Regular intake of psyllium fiber has been linked to reduced blood pressure, lowered triglycerides levels and reduced risk of heart disease.
5. It Can Also Lower Cholesterol Levels
Psyllium is able to bind to fat and bile acids, which promotes their excretion from your body.
In the process of replacing these lost bile acids, the liver uses cholesterol to produce more. As a result, blood cholesterol levels decrease (34).
One study reported an increase in bile acid synthesis and lowered LDL (“bad”) cholesterol in 20 individuals treated with 15 grams of psyllium daily for 40 days (34).
In another study, 47 healthy participants experienced a 6% reduction in LDL cholesterol after taking 6 grams each day for six weeks (33).
Furthermore, psyllium can help increase HDL (“good”) cholesterol levels (18, 19).
For instance, taking 5.1 grams twice a day for eight weeks resulted in a decrease in total and LDL cholesterol, as well as an increase in HDL levels in 49 patients with type 2 diabetes (18).
Lastly, one study treated 125 type 2 diabetics with 5-gram doses of psyllium three times a day for six weeks. Participants experienced increases in HDL cholesterol up to 45.7% (19).
Interestingly, a review of 21 studies reported that reductions in total and LDL cholesterol are dose dependent. This means greater results were observed with treatments of 20.4 grams of psyllium per day than 3 grams per day (35).
Bottom Line: Psyllium can lower total cholesterol levels by promoting the removal of bile acids from the body. It has been shown to lower LDL cholesterol and increase HDL cholesterol significantly.
4. It May Boost Satiety and Aid Weight Loss
Fibers like psyllium that form viscous compounds can help control appetite and aid weight loss (20, 26, 27, 28).
One study had 12 healthy participants consume 10.8 grams of psyllium immediately before a meal.
They experienced significantly delayed stomach emptying from the third hour after the meal and prolonged sensations of satiety six hours after the meal (29).
Another study explored the effects of two, 20-gram doses in 17 healthy participants. One dose was consumed three hours before a meal, while the other dose was consumed immediately before a meal.
The results indicated increased feelings of fullness one hour after the meal and reduced total fat intake during the day, compared to the placebo (30).
However, studies investigating a direct relationship between psyllium and weight loss seem to show mixed results.
One study found that 16 weeks of a calorie-restricted diet paired with three grams of psyllium either twice or three times daily resulted in an average weight loss of 9.9 pounds (4.52 kg) and 10.12 pounds (4.60 kg), respectively (31).
Furthermore, another study showed that psyllium supplementation on its own, as well as paired with a fiber-rich diet, resulted in a significant reduction of weight, body mass index and percentage of body fat (32).
In contrast, other studies did not report significant effects on body weight (19, 33).
Bottom Line: Psyllium aids appetite control by slowing down stomach emptying and reducing appetite. Decreased appetite and calorie intake may support weight loss.
3. It Can Lower Blood Sugar Levels
Fiber supplementation has been shown to control glycemic response to a meal and reduce insulin and blood sugar levels. This is particularly the case with water-soluble fibers like psyllium (16, 17, 18, 19, 20).
In fact, psyllium works better than other fibers like bran. This is because its gel-forming fibers can slow down the digestion of food, which helps regulate blood sugar levels (21, 22).
One study treated 56 diabetic men with 5.1 grams of psyllium twice per day for eight weeks. It reduced their daily blood sugar levels by 11% (23).
In another study in people with type 2 diabetes, a higher daily dose (five grams consumed three times per day) for six weeks resulted in a 29% reduction in blood sugar levels within the first two weeks (19).
Because psyllium is able to slow down the digestion of food, it’s recommended to take it with food, rather than on its own, so it has a greater effect on your blood sugar levels (22).
It seems that a daily dose of at least 10.2 grams can promote lower blood sugar levels (23, 24, 25).
Bottom Line: Psyllium is able to delay food digestion, which helps regulate blood sugar levels. A daily dose of 10.2 grams ingested with meals appears to significantly affect blood sugar levels.
2. It May Help Treat Diarrhea
Psyllium has also been shown to relieve diarrhea (2, 11, 12, 13).
It does this by acting as a water-absorbing agent, which can increase stool thickness and slow down its passage through the colon.
One study showed psyllium husk significantly decreased diarrhea in 30 cancer patients undergoing radiation therapy (14).
Another study treated eight people who had lactulose-induced diarrhea with 3.5 grams, three times daily. Doing so increased their stomach emptying time from 69 to 87 minutes, which meant fewer bowel movements (15).
So psyllium can both prevent constipation and reduce diarrhea, effectively helping to normalize your bowel movements if you are having problems.
Bottom Line: Psyllium can help treat diarrhea by increasing stool size and slowing its passage through the intestinal tract.
1. Psyllium Relieves Constipation
Psyllium is used as a bulk-forming laxative. It works by increasing stool size and therefore helps relieve constipation (5, 6).
Initially, it works by binding to partially digested food that’s passing from the stomach into the small intestine.
It then helps with the absorption of water, which increases the size and moisture of stools. The end product is bigger and more easily passable stools (3, 7, 8).
One study found that psyllium had a greater effect than wheat bran on the moisture, total weight and texture of stools (9).
Another study showed that taking 5.1 grams twice a day for two weeks significantly increased the water content and weight of stools, as well as the total number of bowel movements, in 170 individuals with chronic constipation (10).
For these reasons, taking psyllium supplements promotes regularity.
Bottom Line: Psyllium is known as a bulk-forming laxative that helps relieve constipation and promote regularity.
