    I have been taking these for a few years now and wouldn't be without them, they do wonders for my mood, if i run out and do not take them for a few days i turn into the Hulk, they really do level me out and have got me through some stressful times.

    Feel much better

    By Mrs J Richards - 27 June 2014

    I have found taking this once daily for at least 2-3 days helps to improve my mood and I feel a better sense of wellbeing. I have used 5HTP for many years and have found the Higher Nature tablets to be good quality, effective and from a trustworthy brand. I use patches now more often than tablets, but would always trust Higher Nature for tablets.

    Surprisingly effective

    By Mr B Grima - 26 June 2013

    I buy supplements with the expectation that I won't notice any difference whatsoever. How wrong I was. The first night I took this I slept 3 hours longer than usual, in deep, uninterrupted sleep. Since then it has remained effective. Expensive, but recommended.
