What is Slippery Elm Bark Extract?
Slippery elm bark extract is derived from the inner bark of the slippery elm tree, a species native to North America. Slippery elm bark extract is widely used in dietary supplements, herbal formulations, throat-care products, and digestive health products.
The main active ingredients in slippery elm bark include mucilage polysaccharides, tannins, calcium, magnesium, and phytosterols. Among these, the mucopolysaccharides form a soothing gel when mixed with water. This gel can be used to relieve discomfort in the throat, stomach, and intestines.

Slippery Elm Bark Extract Benefits
1. Helps Improve Digestive Function
Is slippery elm bark extract a laxative? Although it works differently than some other laxatives, it seems to improve symptoms of constipation, IBD and IBS, including in both adults and children. The fresh inner bark can be used in place of, or along with, other natural laxatives.
In one study, the effects of two different formulas on digestive function were compared, both of which included SE in addition to other herbs.
Formula one was associated with a small but significant increase in bowel movement frequency, as well as reductions in straining, abdominal pain, bloated stomach and IBS symptoms. Subjects who took formula two experienced a 20 percent increase in bowel movement frequency and significant reductions in straining, abdominal pain, bloating and global IBS symptom severity, as well as improvements in stool consistency. Ultimately, both formulas led to improvements.
SE has also been shown in certain studies to treat diarrhea and diverticulitis. Additionally, it may help protect against ulcers and excess acidity in the GI tract because it causes reflux stimulation of nerve endings, and that reaction leads to increased mucus secretion. Not only does this help most people, but it can actually give much relief to your dog too.
2. May Aid in Weight Loss (When Combined With a Low-Calorie Diet)
Since slippery elm bark extract has the ability to improve digestion, this may aid in weight loss.
A study performed at New York Chiropractic College used normal participants from the faculty, staff, students and community members to participate in a 21-day weight loss program. Nutritional supplements containing digestive enzymes that were intended to facilitate digestion, reduce cholesterol levels, increase metabolic rate and mediate inflammatory processes were consumed 30 minutes before each meal.
The regimented supplementation program included daily supplementation with a one green drink, as well as a "cleanse supplementation" containing slippery elm plus other herbs and minerals. The cleansing mixture was taken before each meal during week two of the study. During week three, the cleanse supplementation was replaced with prebiotic and probiotic supplementation.
At the end of the study researchers found that participants experienced clinically meaningful reductions in weight and low-density lipoprotein cholesterol. It was concluded that "Weight loss and improvements in total cholesterol and low-density lipoprotein cholesterol levels occurred after a low-energy-density dietary intervention plus regimented supplementation program."
3. Can Help Reduce Oxidative Stress
Because it contains compounds called phenolics, slippery elm bark powder organic may act as a natural free radical scavenger and fighter of oxidative stress.
Phenolic compounds have been shown to trigger cellular responses that combat oxidative stress, a contributing factor to aging and various chronic diseases. Plant phenolic compounds also appear to help fight pathogens through their natural mechanisms.
