Biosil® is generally very well-tolerated. No side effects have been reported in clinical studies using Biosil®. Since 1994, a few of our customers have reported reactions which suggest they are extremely sensitive to choline (the essential B vitamin-like nutrient that stabilizes the orthosilicic acid in ch-OSA®). Common signs of too much choline can include symptoms like GI distress (i.e. constipation, nausea, and/or diarrhea), accelerated heart rate (including heart palpitations), and nervousness.

According to data from the National Health and Nutrition Examination Survey, 90% of Americans don’t get enough choline in their diet. The average American women eats 260 mg of choline per day (men eat roughly 400 mg, on average). The recommended daily dose of Biosil® (two capsules or ten drops) adds 200 mg, for a total of 460 or 600 mg of choline per day, by gender. This is just slightly above the adequate intake recommended by the Food and Nutrition Board (425 mg for women, 550 mg for men) and is usually a very good dose. This is well below the upper tolerable limit for choline, which is 3500 mg per day for both women and men.

Most people benefit from the choline in Biosil®. However, very rarely, some can be extremely sensitive to it. In rare cases where choline sensitivity is a problem, taking Biosil® with food can help soothe the symptoms. Also, lowering the dose is often effective.
