Serene 5-HTPpaypal-page.png

For enhancing mood and improving sleep

It’s no fun feeling low in mood. Everything feels like an effort. You feel exhausted and anxious all the time and getting a decent night’s sleep feels beyond you. In a nutshell, you feel out of sorts. It’s tempting to suffer in silence or ask your doctor for a prescription. But there could be a much more natural way to boost your mood.

best 5-htp supplement

Our Natural 5-HTP capsules are an easy and convenient way to get you back in the driving seat.

5-HTP is a naturally occurring amino acid that makes Serotonin, the chemical found in the brain and intestine. It influences a number of body and psychological functions and is often thought to be responsible for maintaining mood.

Our 5-HTP capsules are a natural anti-depressant and contain extracts from the Griffonia Seed, a West African Plant. We also use a specially developed process to retain as much of the active components of 5-HTP as possible. So however you feel right now, better days are just around the corner.

Natural 5-HTP is ideal for:

  • Reducing symptoms of anxiety
  • Improving sleep
  • Restoring normal levels of energy
  • Improving concentration

And free from:

  • Fillers and Binders
  • Preservatives
  • Artificial Sweeteners, Colours and Flavourings
  • Sugars
  • Suitable for Vegetarians

What our customers say.... 

"I have really benefited from 5-HTP and feel compelled to share my story

I have suffered from anxiety all of my life, with heightened anxiety whenever I am away from home. Because of this, I keep the time a spend away from home to a minimum. 

Last year my husband and I were travelling back from Egypt and suffered massive flight delays. My husband was talking with the airline to try arrange a replacement flight ASAP, but was having no such luck. After a 4 hour wait, the airline finally managed to put us on an early flight the next morning, so we set up camp in the airport departure lounge and waited to board our flight back to London. 

Luckily our travels from there were smooth and we got back home safely. Why I am even sharing this story? Well, it wasn't until after we arrived home, that we realised just how calm I was and how well I handled the delays. Normally, I would have been a mess in complete hysterics imagining all sorts of horrible things :-( The only thing that had changed was me taking 5-HTP. I know swear by it and happily recommend to my friends and family 

I hope this helps anybody who suffers from anxiety some relief, as no one deserves to feel on edge all of the time.

Thank you 5-HTP,

- Mrs Debbie Coone

"Unable to take medication for my depression, something I had suffered longer than I care to remember, a friend recommended I try 5HTP. She described it as natures way of rebalancing the mind. After just a couple of weeks I noticed a massive difference in my energy levels and general interest in life. I no longer felt exhausted and lethargic, but normal again, the first time in a long time. I've stuck with it and 9 months down the line I feel great, even playing tennis again. I can't thank my friend enough"

- Mrs Hillier

"When a friend recommended these I was sceptical, but I started taking them a few weeks ago and have already started noticing the difference. I have always had a hyperactive mind and find it very difficult to relax and to sleep. Since taking these I have started to be able to switch off from the day's work and begin to relax before bedtime. I have been getting much more restful sleep. I have actually been waking up feeling refreshed from my sleep! Which has not been the case for a very long time. So, I actually do feel more Serene.. Very pleased with them."

- Ms J Booth

"For a while now everything has felt like a massive effort and I have been feeling really exhausted so rather than going to my doctor, my husband suggested I take some vitamins and recommended these so I ordered some. So glad I did! I have been taking them for a few months now and they have really helped! I no longer feel so drained! I would definately recommend if your feeling a bit low."

- L Clarke

"Love this product, had been feeling really down, depressed and suffering from anxiety, and had been without a good nights sleep for so long, but I was reluctant to do on to anti-depressant's so after being recommended I decided to give these a try... WOW what a difference after only 10 days. I'm feeling so much better now, no low moods and not feeling any anxiety, and best of all i'm getting a good nights sleep!! Thank you 365 Vitamins, I will be buying from you again and recommending you to my friends!!"

- Ms D Beaton

"Have been suffering from mild insomnia for the past 4 months. Started using these over the last week and have seen positive improvements!"

- E Preston

"Had been suffering from depression and anxiety attacks for years.. I've probably been placed on every anti depressant under the sun, some making me feel suicidal, was told about 5-HTP from a family member and thought why not!! What have I got to lose.. !! Can honestly say after 1 week I could feel a difference and I'm now on week 3 and I feel a completely different person xx thank you 5-HTP"

- Ms D Mannell

  1. Good return for only 2 weeks. 4 Star Review

    Posted by on 20th Feb 2018

    I'm feeling a good return from the product with only 2 weeks of use.
    I'm starting to sleep better and feeling more up to do my daily workouts.

  2. Happy customers 5 Star Review

    Posted by on 9th Apr 2017

    I ordered these for my best friend who goes through hard times in her life, feeling down often, easily crying, swinging moods. When I told her about these capsules, she got really excited to get some help. Now she is taking them for a week, and she says they do miracles. Her self esteem is much higher, as she says: "I notice the sun now!', which is sad but optimistic at the same time as well. Also, she mentioned that now she sleeps much better, walling asleep easier and not waking up often as she use to do.
    I am sorry I haven't tried them myself, but as I said, I ordered them for her, because she is the one who needs help. I can be only happy for her. So, on her they have the promised effect.
    Just to mention, the ordered arrived promptly, and I liked the bottle, which is flat and goes through the letter box, which saves you journeys to the post office, in case you are not at home.

  3. I love these new flatter letter box friendly bottles – great ... 5 Star Review

    Posted by on 18th Mar 2017

    First of all, I love these new flatter letter box friendly bottles – great idea, saves on postage, and the postie can get it thru the letter box (if not posted in a box that is).
    I have used various tablet based supplements for sleeplessness over the years - but found things like night nurse just kept me awake, so wanted to try something more on-going. The supplement is a serotonin booster supplement. I think thou they are effective as a long term solution as I think this type of boost takes some time to balance and get into the system. (It also states not to take them if you are on anti-depressants.) You can take up to 3 per day, but I think it is best to work out what best amount and when suits you. I have taken one in the morning, and one a few hours before bed.

    The bottle is simply designed, and foil sealed at the top. The lid is pretty easy to open too, simply flip it upwards with your thumb. The bottle contains 90 capsules, between 1 and 3 months’ worth – so a great number in the bottle.

    Having taken them for a couple of weeks, I've seen a shift in my sleep pattern as it has regulated, I think I’m getting ‘better’ sleep. So am happy with these.

  4. It makes me feel so much better 5 Star Review

    Posted by on 22nd Feb 2017

    After taking this pill I feel more alive and energetic. I'm less moody and I like to plan for my day. I severed from PMDD before but my symptoms improved a lot. I can do my daily activities more efficiently and I don't feel tired. I also go to sleep easier.
    It reduces my negative thoughts. I have not noticed any side effect.
    It's so much better than antidepressant because mind remains sharp.
    I'm really happy that I found this product and I felt better without taking any chemicals. I read about 5htp and I bought this precious product on a discount . I mention a part of article that I read below.

  5. Lovely product giving a very subtle boost to your day :) 5 Star Review

    Posted by on 25th Jan 2017

    So I came across the capsules when doing some research into alternative and less well known therapies and treatments for anxiety and stress. I have times in my life where little things just stress me out more than usual, my sleeping pattern isn't as easy to maintain, and so far I haven't seemed to have found a perfect solution. I've had nothing but excellent experiences with this company so far, so I felt confident in ordering this product to give it a go!

    I'm aware from my research that the capsule isn't something that should be taken regularly for long periods of time. However, studies show that it can have some helpful short term effects. I think with trying any supplement, you should always have reasonable expectations before starting- if miracle cures existed for things, it would be very well known.

    So as with other products from this company, the little capsules come beautifully packaged in a neat little handbag friendly box. You also get a lovely friendly email from the owner of the company containing some further information about your product and the offer of help should you have any further questions- very reassuring when trying something new!

    The tablets themselves seem pretty standard, no aftertaste with these ones unlike some others. The effects? Very subtle but definitely there. Within a few days I was really noticing how I felt just that little bit more relaxed, my sleeping had improved and both of these things have a knock on effect to your overall state of mind and how positive you feel. I am by no means saying that these are a guaranteed cure for any stress conditions- you should always work with a doctor to discuss issues like that but for a normal fairly healthy person just looking to feel that little bit better, these are well worth the buy in my opinion! I'm very happy I tried these, they make a nice little addition to a daily routine.

  6. Awesome! 4 Star Review

    Posted by on 13th Jan 2017

    This week I have been tesing and reviewing the supplement.. 100mg capsules. Letter box friendly packaging. GMP certified. The supplement is a naturally occurring amino acid from which the neurotransmitter serotonin is made

    I have never before heard of the supplement but I am currently dieting and read up on this somewhere online so thought it might be nice to try it out.
    The delivery was quick, thank you.
    It comes in a large bottle, which is very well sealed for safety and security. The bottle has an attractive look to it, it looks right at home on the shelf in my kitchen along with my workout supplements and meal replacements. My 'health shelf' is becoming a rather interesting and attractive place, thanks to the nice pakcaging so I am glad that these fit in well and look good with the rest.
    It is made very clear what is in them, and the amounts of the active ingredient (which is a good amount, better than some I have looked at with only a small amount of active ingredient)
    The capsules are quite large but easy enough to swallow, no taste or smell that I can say that I have noticed.
    I have only been using them for a short amount of time and I have to get my review written quickly to follow the terms and conditions of being a reviewer so although I can not yet comment on how effective they are, I will definitely return to this review in a month or so and update it with some longer term results on how this has worked for my appetite supression, metabolism boosting, weight loss, and energy boosting. I have read fantastic things about this supplement though, and I am extremely excited to be trying it out and very confident that it will work in the way it is supposed to.
    I was lucky enough to receive this bottle of dietary aid supplements in return for an honest review, which I promise I will add to once I have used them long enough to review the effects as well as just the product itself.

  7. I like to take one of these tablets in the morning ... 4 Star Review

    Posted by on 20th Dec 2016

    I take these capsules as I have recently came off some depression medication and I needed something to top up my Serotonin as that is what the supplement does, It helps your brain to make more Serotonin.

    I like to take one of these tablets in the morning and one at around 4-5 in the afternoon. They make me feel calmer and more relaxed and I do feel I have more energy in a good way not a caffeine buzzing way, But they also help me to sleep deeper which is a god send for me as I find it hard to stay asleep.

    This pack contains 60 tablets each with 100mg of , and the dose is 1-2 tablets a day, So I find they last me one month.
    The tablets are odourless and tasteless and they are not big so they are easy to take, and they don't repeat on which is always good.

  8. helps me 5 Star Review

    Posted by on 11th Dec 2016

    These are really easy to take and come in a little plastic box. I do find them help me relax at night and go off to sleep much easier, I was given these in exchange for my review so I hope this helps. Do your research before taking these because they can interact with other tablets.

  9. Great product 5 Star Review

    Posted by on 11th Dec 2016

    I have been taking this supplement for some time now and I'm very pleased with the results. I take it for low mood and to help me get a better night of sleep and I have found it to be a very positive supplement and a great alternative to prescription medications which, unfortunately, I suffered bad side effects from. If you are considering taking 5-HTP for clinical depression or medical issue it's wise to speak to your doctor first.

    I have found (through trial and error) that the best dosage for me is around 300 mg per day. I have purchased another batch product from Amazon which works well but it's in 200mg capsule form which can't be split. This particular product is perfect in that the capsules are 100mg in dosage so it's very easy to take the amount you need without worrying to find a product that can be split.

    These are very easy to take (I take them at night with a glass of water) and the product works out to be very cost effective for me in that there are 90 capsules in a pack so these will last for a while.

    The capsules arrived very quickly and were well packaged. This product is also 'letterbox friendly' meaning you don't have to be around to sign for a package etc.

  10. Great supplement 5 Star Review

    Posted by on 19th Nov 2016

    This supplement is definitely worth a try if you suffer from anxiety, depression or bad sleep issues. It's nice to have a natural alternative so you don't have to worry about taking this. I have recommended this to some friends as well to try and only heard good things back. The capsules are a good size and easy to swallow and I like the positive, bright packaging. It also comes quickly if you are a Prime member and as far as supplements go the price is very reasonable.
