When buying natural supplements, we heartedly recommend to book a free consultation with our online Nutritionist to check suitability in order to avoid possible interactions that may occur when combining natural supplements with prescription medications, OTC's and other supplements at higher doses than the daily recommendations. We have a 15-minute free of charge consultation service available 7 days a week from 09:00 am to 07:00 pm (London time). Just select a day from our calendar and a time suitable to you.
