serotonin vs dopamine 

Serotonin is your feel-good chemical messenger regulating positive mood [1]. At night, serotonin converts to your sleep hormone melatonin, promoting restful sleep [2,3].

Dopamine is your reward and pleasure chemical [4]. Dopamine is released when you derive pleasure from activities such as great food and accomplishment. It is also linked to alertness and motivation [5,6].

how to increase serotonin and dopamine

Serotonin and dopamine supplements are often misunderstood—these neurotransmitters are unable to enter the brain. Instead, you need to consume their building blocks—like 5-HTP for serotonin, and L-tyrosine for dopamine—which the brain can use to naturally produce more of these chemicals.

5-HTP is naturally created in the body from the dietary consumption of protein-rich foods, which contain the amino acid tryptophan. Whilst both are building blocks to serotonin, 5-HTP provides a more direct and efficient route to increasing serotonin levels.

Tyrosine is a natural isolated nutrient and the building block to your reward and pleasure chemical messenger, dopamine [4]. Tyrosine goes through a conversion process before it forms into your brain chemical dopamine.

FAQ's

How/when should i take them? + -

Take 1 5HTP capsule with a meal. Serotonin plays an important role in regulating mood and sleep. It's recommended you take 5-htp as/when you have an emotional need for the product.

Take 1 capsule 800mg tyrosine with or without food. Dopamine plays an important role in alertness and motivation and is often taken in the morning but some people take it before going to the gym

What’s the difference between dopamine and serotonin? + -

Serotonin is your feel-good chemical messenger, which plays an important role in regulating mood, whereas dopamine is your reward and pleasure chemical messenger, also linked to motivation and alertness.

How to test serotonin and dopamine levels ? + -

You can’t directly measure serotonin or dopamine levels in the brain. This is because the blood-brain barrier stops these chemicals from moving into the blood, so standard lab tests can’t detect them accurately. Instead, doctors look at symptoms or use indirect testing methods.

Can you take serotonin and dopamine supplements together ? + -

You can use 5HTP and Tyrosine together. They work on different chemical pathways and they do not contraindicate. There may be a synergistic benefit of taking them in combination however, the synergistic benefit at these specific mg dosages hasn't been studied in clinical trials.

Are there any contra-indications? + -

5-htp should not be taken with any anti-depressant medication.

This is an easy vitamin to swallow, no taste and no smell, price point is great for the amount you get. Unfortunately I did not find that I can sleep better at night or felt my mood improved. Maybe I need to take them for a prolonged period of time.

Prodotto nel Regno Unito da Brain Feed ltd, azienda specializzata in integratori per migliorare la salute e le prestazioni del cervello.Pro:- Principio attivo naturale;- Alta concentrazione;- Qualità certificata.Contro:- Info e istruzioni in lingua inglese.Ho atteso un paio di settimane prima di scrivere le mie opinioni riguardo questo integratore.Questo poiché non sono ancora sicuro d'avere ottenuto effetti evidenti assumento il 5-idrossitriptofano (o 5-HTP). In verità non ho alcun problema a prendere sonno e non mi svegliano neanche le bombe.. ma avendo una vita abbastanza stressante tra lavoro ed impegni familiari sono sempre teso ed un po' "ruvido" nei rapporti con gli altri.. e avrei bisogno di ritrovare serenità e positività .Forse un minimo più tranquillo e disponibile lo sono.. ma probabilmente mi aspettavo un risultato maggiore e forse la sintesi della serotonina/melatonina nel mio corpo è comunque già ottimale di suo.4 stelle le ritengo in ogni modo giuste.. il brain feed 5 htp è un integratore che contiene in alta concentrazione e biodisponibilità il suo principio attivo che viene estratto dalla Griffonia africana, pianta che viene coltivata e raccolta in maniera ecosostenibile.La 5 stella poiché il 5-idrossitriptofano è un derivato amminoacidico ben studiato e gli vengono riconosciute l'efficacia d'incrementare i livelli dei neurotrasmettitori come la serotonina (regola l'umore, il sonno e il senso di fame), la melatonina (regola il ritmo sonno-veglia) ed anche la dopamina, la noradrenalina e le beta-endorfine.Pertanto è utilizzata nei trattamenti contro l'abbassamento del tono dell'umore, dell'insonnia e anche l'eccessivo appetito.La posologia indica l'assunzione di una pastiglia 90 minuti prima di andare a letto per aiutare/migliorare il sonno, massino 2 pastiglie al giorno, uno dopo ogni pasto, per migliorare l'umore.Queste sono molto piccole e facilmente ingeribili e io non ho mai avuto alcun effetto collaterale negativo durante la digestione.Unica attenzione, non si possono assumere se già trattati con altri anti depressivi!

Since I started taking it I am sleeping a lot better. It tastes a little as medicine as it doesn’t have those plastic case but it is not horrendous. Easy to swallow. Great package.

5-htp 100mg Capsules

Customer photo review of 5-htp 100mg Capsules

April 2021 - still have quite a few tablets left of these. I don’t recommend these to be taken everyday rather when mood drops. I find that if I take one a day for 2/3 days then my mood levels really well. If I take it when I’m not experiencing low mood I tend to feel a little manic. So for me these are fantastic as I take it if my mood drops really low with no explanations ie PMS or seasonal change mood issues. I don’t find them addictive so highly recommend them.August 2020 There really is no happy pill. Truly there is no pill that you can take to take away your troubles or fix your problems. That shift takes place in your mindset. You can search the ends of earth for a remedy but nothing will be lasting until the shift takes place inside your mind space. I say this because i read reviews where people have immense expectations from a pill and it's heart Breaking because they're disappointed in the product but its not the products lack but them having unrealistic expectations.Enjoy and go easy on yourself!

Customer photo review of 5-htp 100mg Capsules

I used this for a few weeks and I thought it is a really good product.The packaging is easy to use and the tablets are very easy to swallow. I was only having 1 a day but I felt it lift my sense of wellbeing and feeling positive.I had also been using theanine from brainfeed and the combination of both of these were very helpful. I feel like it helped me sleep better as well.I haven't used 5-HTP before but it has been useful to have this especially during the stressful time at work, I feel like it supports my mental health better.I think when combined with other things like good nutrition, better sleep hygiene, use of mindfulness/meditation then it can be very useful and I felt the benefits and will continue taking this.

Customer photo review of 5-htp 100mg Capsules

Per chi non lo sapesse, la griffonia è una pianta africana i cui semi sono naturalmente ricchi di L-5-HTP (L-5-idrossitriptofano), un precursore diretto della serotonina.La griffonia è quindi una sostanza che offre un aiuto naturale per recuperare la calma, la serenità e la qualità del sonno.L’L-5-HTP presente nella griffonia non presenta gli effetti collaterali degli antidepressivi di sintesi né rischi di assuefazione. A differenza degli antidepressivi di sintesi, permette di ridurre gli stati d’ansia e depressivi senza alcuna controindicazione per il funzionamento naturale del cervello.Tutto questo preambolo per dire che… a me non fa alcun effetto!Ebbene, anche prendendo il doppio della dose consigliata (4 capsule invece di 2, sempre di sera) non ho riscontrato significativi cambiamenti nel mio sonno, né sul tempo di addormentamento, né sul proseguo del sonno stesso, e nemmeno sull’umore in generale (è rimasto sempre il medesimo).Passi che il prezzo non sia molto popolare (19 euro), passi che il flacone sia in realtà una busta (!), passi che le indicazioni siano esclusivamente in inglese, passi che le compresse non siano di facilissima deglutizione, ma che proprio non vi siano effetti “visibili” nemmeno con dosi da elefante proprio non lo digerisco.Peccato, ma per me 2 🌟 e non di più.

Customer photo review of 5-htp 100mg Capsules

I used to take those when I was struggling with depression and insomnia and they really do help. They are not recommended to take continuously. I started taking them again due to stress with work and covid pandemic and I do sleep better, but I do tend to get very vivid and strange dreams that sometimes feel too real – not nightmares though. I do feel much better since taking them, but I have to say they are pretty expensive for the amount you get as I used to buy them 4 times cheaper - this is why I give 4 stars

5-htp 100mg Capsules

Customer photo review of 5-htp 100mg Capsules

Opening note, I have tried various prescription medications to alleviate my symptoms over the years. I'm also under a mental health team and have close support. However if you or someone else you know is struggling and considering taking this to help with that please speak to someone you trust first about how you have been feeling. Talking can make things better and support is needed on top of things like this, it is not a stand alone cure.On to the review! I had high hopes for this supplement and went into it very positive. I suffer from complex PTSD, moderate depression, moderate anxiety and sleep issues, I'm also a busy mum with two children and studying from home. In the description it states "ideal for anybody with lower than normal mood" "people who struggle sleeping" "people with a busy lifestyle" so these supplements are definitely aimed at someone like me!(I'm not taking any prescription medication for my mental health so I was clear to try these, if you are taking any regular medication please speak to your doctor first)I've taken a dose of 2 a day (morning and evening) for 4 days given my mental health is quite poor I wanted to try the larger dose. After contacting the seller I was advised I should notice a change immediately, so I am reviewing it now based on that advice.Does it help you sleep? In my opinion no. I have uploaded screenshots from my fitness watch to show my sleep this last couple of days, that is how it always is, I have terrible issues waking frequently through the night and really struggle to get restful sleep. I really hoped I would see some improvement but I sadly haven't. I'm still waking multiple times a night and have not noticed any more refreshing or deep sleep. Lost a star for that.Has my mood improved? Not that I have noticed, I certainly haven't been miserable constantly but I tend to have good and bad days anyway. Yesterday was a bad one and I was on day 4 of taking them. Lost a star for that.Have I noticed any side effects? No bad side effects that I have noticed, but I have health issues so anything like that I may not notice or assume it is down to my fibromyalgia.Price, was it worth it? For me it is a little expensive, especially considering they didn't do much for me. I don't think I would be willing to keep going with it long term to see if it helps purely based on price. So it lost a final star there.Positive points, I like the packaging it looks clean and was easy to open. I also like that it is UK manufactured. 1 star for that.Plant based so vegan friendly! So many supplements have hidden animal produce in, so knowing these are vegan is definitely a plus. Also as stated they are indeed easy to swallow. And didnt have a bad taste. Awarded a second star for that.Over all for me they didn't help, they may for someone else but personally I won't be making these part of my daily routine any time soon.Note: If you are struggling with your mental health please speak to someone, a trusted friend, family member, even doctor. It is okay to talk! Don't suffer alone in silence.

Customer photo review of 5-htp 100mg Capsules

I've used 5 htp before so I knew what effect I was looking for when taking this brand.I definitely felt more rested upon waking and recommend pairing this with ZMA also for an even bigger impact.I don't like the fact that the tablets are not in a hard bottle, and that they are not capsules which I find easier to swallow but aside from that I think they are great.Cost at time of this review was £14.45 for 60 which is very reasonable for what works out to a 60 day supply for me.There is a lot of choice on brain-feed for 5 htp, these are vegan if that matters to you and from what I have felt they do work, so if you think you might benefit from these don't be afraid to give them a try.I hope you found this review useful :)

Customer photo review of 5-htp 100mg Capsules

Recently I was constantly feeling down. Some personal perturbations , too much work and the most important very stressful Covid situation caused that I started having bad mood and problems with sleeping. There were days I didn't have enough will power to get out of the bed and start my day. I was nervous and unpleasant for family.I didn't really believe that serotonin enhancement pill could work. But they do ! I am taking one every morning along with my breakfast, making sure to drink lots of water with it.My mood has improved drastically. I am much happier, more optimistic, I have so much more energy. I don't feel down anymore.I'm testing them almost a month now and did not notice any side effects. Easy to swallow, no smell or aftertaste.Mood and life changing pills - highly recommended !

5-htp 100mg Capsules

Customer photo review of 5-htp 100mg Capsules

I have been taking 5HTP for about a year since I transitioned off SSRIs (prescription anti depressants). I previously tried St John's wort as a natural mood booster but the problem is it interacts with so many other medications. So I started taking 5HTP which doesn't have any medication interactions that I know of (can't guarantee that though, please consult with your doctor).I have been genuinely pleased with the results. I have never found that it makes me sleepy and I do believe that it has a very minor but very welcome effect on regulating my moods.This brand is in tablet form whereas previously I have always taken capsules. They are OK to swallow, no particularly bad taste or smell. The packet is neat and small. The main issue I have is that these are quite expensive compared to other brands I have had before, so for that reason I gave it 4/5 stars.I hope this is helpful.

This isn't a cure for anxiety but I've found mine can be triggered by workload and this is the best natural solution I've found for worry/workload/stress. Only take this during the day if you're looking for an improvement in mood. When I've taken this at night it can sometimes make me sleepy.

Had high hopes, have been taking these for two weeks now but sadly no change in my mood or sleep patterns, I will keep taking them for the rest of the pack in the hope of some effect.

Not sure it is working for me. I am not getting better sleep. Still waking up during the night and feeling groggy in the morning.

5-htp 100mg Capsules

Store owner replied: Hi Mohammed, 5-htp’s primary benefit is to support serotonin (5-ht) production. The brain biosynthesises melatonin (your sleep hormone) from serotonin. This biosynthesis is triggered by a reduction in UV levels (ie: it must be dark and no blue light emitting from electronic devices). If you’d like to discuss your experience further or explore a solution, please feel free to reach out to us at info@brain-feed.com. [Christine - brain feed customer services]
