Roll Call does not check drug interactions or assess personal safety.

Oil pressed from sunflower seeds, commonly used in supplements as a carrier or filler oil in softgel capsules.

Why it’s used

Used for a manufacturing role, to deliver fat-soluble ingredients in softgel form or to bulk out capsule contents, rather than for an effect of its own.

What the evidence says

No efficacy question applies, since it is not included for a health effect. There is nothing unusual to report about a common food oil used this way.
