18 Jun 2019 --- Neopac and Streuli Pharma (Streuli) are simplifying vitamin D supplementation for children with the launch of a dropper tube, which enables a safer and more precise administration of doses. Streuli manufactures the oil based supplement, D3 piccolo, while Neopac’s Polyfoil dropper tube allows for a simple dispensing of the oil on a drop-by-drop basis. Traditionally, vitamin D is packaged in glass vials with pipettes, but the Polyfoil 19mm dropper tubes are glass-free, allowing the metered dropper to be directly inserted into the mouth, as well as being more safely transportable.
