Directions for Preparation and Use:

Suggested Intake

The quantity of Lanaflex is dependant on the age, bodyweight, and medical condition of the individual and is to be determined by a clinician or dietitian only.  The recommended quantity of Lanaflex is 0.8 g per kg bodyweight per day.  This quantity should be distributed over the day in three or more portions taken along with meals.  Do not exceed three sachets per day in total.

Preparation

It is recommended that Lanaflex is prepared at an approximate 1 to 4 dilution.  In a screw top container, add 60 mL (2 fl oz) of chilled water.  Add the contents of one sachet (15.8 g) and shake well until dissolved.  This will yield a final volume of 70 mL (2.3 fl oz).  The product is best served as a chilled drink and consumed immediately.  If taken in a more concentrated form, water or diluted drinks should be taken immediately after Lanaflex.

Precaution:

  • Not for use when planning or during pregnancy
  • Seek medical advice before using with serotonergic medications

Storage:

  • Store unopened sachets in a cool, dry place. Opened sachets should be stored in an airtight container and used within 24 hours.
