Popular questions
Is gellan gum bad for you?
No—it's considered safe by major regulators (GRAS in the U.S., approved in the EU); very high intakes may cause gas or loose stools, but typical food amounts are well tolerated.
What is gellan gum made of?
It's a polysaccharide produced by fermenting sugars with the bacterium Sphingomonas elodea; chemically it contains repeating units of glucose, glucuronic acid, and rhamnose.
Is gellan gum vegan?
Yes—it's made by microbial fermentation and is not animal-derived, so it's generally considered vegan.
Is gellan gum bad for your gut?
Generally no; it's not digested and is used in small amounts, though large amounts can cause bloating or laxative effects in some people, with no evidence of gut-lining harm at permitted levels.
Is gellan gum inflammatory?
No; there's no evidence it promotes inflammation at approved food-use levels, and regulatory evaluations have not identified pro-inflammatory effects.
How to apply calcium alginate dressing?
Cleanse the wound, dry the surrounding skin, then lay or lightly pack the calcium alginate (sheet or rope) to cover/fill the wound without overpacking and cover with an appropriate secondary dressing; it will gel on contact with exudate and lifts out with gentle irrigation at change. Use it on moderate-to-heavily exuding wounds (not dry wounds) and follow product instructions or clinician guidance.
Is calcium alginate and aquacel ag the same thing?
No. Aquacel Ag is a hydrofiber (sodium carboxymethylcellulose) dressing with ionic silver, while calcium alginate is an alginate fiber dressing without silver unless specified; both gel and absorb exudate, but Aquacel Ag adds antimicrobial action.
Is aquacel ag the same as calcium alginate?
No—Aquacel Ag is carboxymethylcellulose with silver, whereas calcium alginate is alginate fiber; they’re different materials even though both form a gel and manage exudate. Aquacel Ag provides antimicrobial silver, which standard calcium alginate does not.
What does calcium alginate do for wounds?
It absorbs moderate-to-heavy exudate and turns into a soft gel that maintains a moist healing environment while helping protect surrounding skin. Its calcium ions can also help support hemostasis in lightly bleeding wounds.
How often to change calcium alginate dressing?
Typically every 1–3 days, or sooner if the secondary dressing becomes saturated; frequency depends on exudate level and wound condition. Always follow the specific product directions or a clinician’s advice.
