I take Oxygen Elements Max in the morning -about 1 drops and if tired later in the day or need extra energy would take another 1 drops. I have found it does help me when I have had a stressful, busy time and have a lot of things to do and notice an improvement generally. When I don't use it and change to another product I realise how effective it is. Would recommend for anyone needing a boost for their general overall health.
