Suitable for vegans
The glazing agents used in the manufacture of capsules are often gelatine, which means that the food supplements are no longer suitable for vegans.
At HSN, we strongly believe that our products should be accessible to everyone, which is why we have used HPMC as a glazing agent.
HPMC, or hypromellose, is an allergen-free vegetable polymer that is completely suitable for vegan diets and can be used to make capsules to coat the food supplement.

I took it to try and I have been taking only one capsule instead of two as recommended. And I have to say that I have been sleeping better, waking up less often and waking up more rested.

L-tryptophan with B6 and B3 is a supplement that helps me a lot to keep my mood stable and reduce mild anxiety. It is especially noticeable if you take it consistently. Ideal for daily routines in times of hard work or when it is difficult to disconnect. Good format and balanced dosage.
