Do not exceed the recommended daily intake. Activated charcoal may reduce the absorption of medicines, including the contraceptive pill, and other supplements, so take it at least 2 hours apart from other medication. May cause black stools, which is harmless. Do not use for more than a few days at a time without advice, and seek medical advice if digestive symptoms persist or are severe. Food supplements should not be used as a substitute for a varied, balanced diet and healthy lifestyle. Keep out of the sight and reach of children. Speak to our pharmacist before use if you are pregnant, breastfeeding, taking medication or under medical supervision.
