Can I take Water Out N90 if I already drink coffee or other caffeinated drinks? — Water Out Food Supplement, N90- VitalHarmony

Water Out N90 contains guarana, which provides caffeine: one capsule contains 11 mg. If you already consume caffeine from coffee, tea or other sources, your total for the day may be higher than usual. For most healthy adults, moderate caffeine intake does not cause problems, but with increased sensitivity it may show up as a faster heartbeat, anxiety or sleep disturbances.

Caffeine from guarana and the polyphenols in green tea are stimulating, so if the product is taken in the evening they may interfere with falling asleep. If you are sensitive to caffeine, or already limit it on a doctor's advice, it is worth discussing this supplement with a specialist before starting a course.

People who cannot tolerate caffeine at all may not be suited to this product; in that case it is more sensible to consider plant-based products without caffeine.
