Chemical Classification: Soluble dietary fiber, Fructan polymer

Overview

Botanical Family: Asteraceae (Compositae)
Primary Origin: Chicory root (Cichorium intybus), Jerusalem artichoke, agave, garlic, onions
Extraction Method: Hot water extraction followed by purification and spray-drying
Molecular Structure: Fructose polymer with β(2→1) glycosidic bonds, degree of polymerization 2-60 units
Appearance: White to off-white, odorless powder with a mild sweet taste

Benefits & Uses

For Women's Hormonal Health:

  • Hormonal Balance Support: Inulin supplementation induced a significant reduction in serum total testosterone concentrations in women with PCOS, helping to address hyperandrogenism
  • Insulin Sensitivity: Recent research suggests that prebiotics may improve insulin resistance and hormonal imbalances by modulating the gut microbiota
  • Weight Management: Inulin slows digestion, including the digestion of carbohydrates, promoting healthy blood sugar levels

Primary Health Benefits:

  • Prebiotic Function: Inulin, as a prebiotic, has an outstanding effect on the regulation of intestinal microbiota via stimulating the growth of beneficial bacteria
  • Digestive Health: Older adults who consumed 15 g of inulin per day reported less constipation and better digestion
  • Metabolic Support: Inulin exhibits excellent health benefits in regulating lipid metabolism and weight loss

Safety & Warnings

General Safety Profile:

Inulin is relatively safe when used appropriately for most healthy adults.

Potential Side Effects:

  • Digestive Effects: Common side effects include bloating, flatulence, and possible stomach discomfort, especially when the dosage is too high
  • Adaptation Period: These symptoms may gradually decrease as the body adjusts to the inulin supplement
  • Individual Sensitivity: If you have a sensitive digestive system or conditions like irritable bowel syndrome, start with smaller doses

Important Warnings:

Start with low doses (2-5g) and gradually increase to allow digestive adaptation
Not recommended during pregnancy and breastfeeding due to insufficient safety data
May cause throat irritation in some individuals - this is normal and typically mild
Consult a healthcare provider if you have IBS, Crohn's disease, or other digestive conditions

Recommended Patch-Test Instructions:

Not applicable for oral supplements. For topical applications containing inulin, perform a 48-hour patch test on the inner forearm.
