Because Biosil® is water-soluble, it’s most effective to split your doses up to keep your ch-OSA® levels consistently high throughout the day. That said, years of customer feedback have shown us that many people can and do take both doses at once without problems.

You should be aware that a very small subset of people with extreme sensitivity to choline may notice side effects if they choose to take both doses at once. If you take both doses at once, monitor for the symptoms of choline sensitivity, such as: GI distress, accelerated heart rate, and nervousness.

Choline is an essential nutrient similar to B vitamins, and is very safe. Taking your Biosil® dose as recommended, or with food, will generally prevent these rare symptoms from occurring.
