5-HTP is an amino acid. Amino acids are substances that build proteins in your body. 5-HTP is related to serotonin, a brain chemical that affects mood, sleep, and pain. It is available as a supplement and is generally considered safe, although some contaminated supplements have caused dangerous side effects.
Your small intestine does not absorb inulin. When it reaches your large intestine (colon), bacteria ferment it.
Why do people take inulin?
People often use inulin to try to treat or prevent digestive problems.
Decrease constipation. In one study, older people with constipation who took 15 grams of inulin daily for a month had less trouble with constipation.
Increase helpful bacteria in the colon. Because it has this effect, inulin is called a prebiotic. Prebiotics may have numerous health benefits. They may:
Help increase the amount of calcium and other minerals you absorb from food
Support a healthy immune system
Relieve intestinal problems
Inulin may also lower levels of triglycerides, a type of blood fat.
Suggested dosages vary by supplement maker. Optimal doses of inulin have not been set for any condition. Quality and active ingredients in supplements may vary widely from maker to maker. This makes it hard to set a standard dose.
Can you get inulin naturally from foods?
Many foods -- and plants that are less commonly eaten -- contain inulin. These include:
Chicory, which is used in salads
Inulin is found in some processed foods as a replacement for fat, such as:
When combined with water in a precise way, it can mimic the texture of fat in these foods.
What are the risks of taking inulin?
Side effects. Inulin may cause allergic reactions, with symptoms that can include:
Avoid chicory if you are allergic to ragweed. It is in the same family. Chicory is also related to chrysanthemums, marigolds, and daisies.
Inulin may also cause:
More frequent bowel movements
Risks. Inulin-type prebiotics are generally recognized as safe. Chicory itself, however, is not recommended in women who are pregnant or breastfeeding. It may lead to miscarriage.
Chicory may also interfere with certain drugs and supplements.
Interactions. Inulin may increase the amount of calcium you absorb from foods.
