How to Take It
Best taken in the evening
Used in the evening for relaxation. Take it with food — the choline in it is what makes this kind of product feel nauseating on an empty stomach.
With food
On the label
Suggested use: Take 2-4 pumps by mouth as needed. Hold 30 seconds before swallowing. Repeat to desired dosage or as directed by a healthcare professional. Take on an empty stomach, at least 10 minutes before meals. Use within 60 days of opening.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
General guidance based on the ingredients, not a substitute for the label or your doctor.
