Jarrow Formulas Lactoferrin, 250mg

Lactoferrin is a protein that occurs naturally in milk; Jarrow Formulas isolates it into a simple capsule format at a stated 250 mg strength.

Pack options are 30 or 60 capsules — smaller counts than much of the Jarrow range, in keeping with the ingredient's more specialist nature, and a gentle entry price for a first try.

The front-of-label strength statement is typical of the brand, whose catalogue of plainly named single compounds is listed in depth at NE Commerce. Lactoferrin sits in the standard pricing tier, and the 30 count keeps the first purchase low-commitment if the ingredient is new to you.
