Which kind of guar gum fits the question?

Guar gum is a seed-derived soluble fiber. Partially hydrolyzed guar gum, or PHGG, has been broken into smaller chains to reduce its thickness in liquids. 1

Cholesterol and bowel comfort are separate questions

Guar gum trials show lower LDL cholesterol, while PHGG studies have examined stool frequency and bloating. The preparation and the outcome matter when comparing a product with research. 2 3 4
