The Health Puzzle

This guide is compiled by The Health Puzzle based on the best available scientific evidence at the time of publication. Research in this field is continually evolving, and findings may change as new studies emerge. We adopt a precautionary approach to our rating system—where credible concern exists, we err on the side of caution. A Yay rating indicates that an item is generally considered safe based on current evidence; it does not constitute a recommendation for individual use. Personal health conditions, allergies, medications, pregnancy, dosage and method of exposure can all influence how a substance affects the body. This guide is intended for general informational purposes only and should not be regarded as a substitute for professional medical, nutritional or health advice. If you are unsure whether a substance is appropriate for your circumstances, please consult a qualified health professional. We review and update this guide on a regular basis. If you believe an entry requires amendment, please contact us a info@thehealthpuzzle.co.uk.
