Seredyn is a kind of mood enhancer containing natural ingredients which affect the brain’s “circuits” responsible for your mood, your emotions and relaxation, to be taken when you’re feeling nervous or anxious.

We looked into Seredyn, its ingredients and how they combine to calm and soothe restless and worried minds.

Seredyn Pros

  • Works for up to eight hours

Seredyn Cons

  • Very strong odour
  • Slower to act if you’ve recently eaten
  • Not to be taken in conjunction with MAOI

What You Need To Know About Seredyn

Seredyn is a product from the BioNeurix Corporation, who also produce Amoryn, a long-term mood enhancer, and Mellodyn, to promote better sleep.

Unlike Amoryn – which needs to be taken on an ongoing basis – Seredyn can be taken as directed and as needed to relieve “occasional anxiety”.

BioNeurix say there’s no risk of becoming dependent on it or suffering withdrawal symptoms if you haven’t taken it for a while.

What Are The Side Effects Of Seredyn?

Like many mood enhancers, Seredyn can cause drowsiness. BioNeurix recommends using caution when driving or operating heavy machinery, and avoiding alcohol until you’re familiar with Seredyn’s effects.

Other side effects include fatigue, stomach upset and headaches. However 4 out of 5 users reporting side effects describe them as “mild”.

How Much Does Seredyn Cost?

One bottle containing a 30-day supply of 60 capsules costs $34.95. Discounts are available when buying 2, 3 or 6 bottles, but they soon get eaten up in shipping charges if you’re ordering from outside the USA.

Unopened bottles can be returned for a refund within 60 days of shipment, and up to one opened bottle per customer can be returned, subject to a $10 processing fee.

Be aware, though, that refills shipped automatically as part of BioNeurix’s autoship program can also be returned – but only within 20 days of the shipment date.

Our Verdict On Seredyn

Although the makers claim that Seredyn isn’t addictive or habit-forming, they also advise users who’ve been taking it daily for one month or more to taper down the dosage to zero over up to 21 days. Gradual discontinuation, they say, may reduce the likelihood of anxiety-related symptoms returning.

This makes us think that despite the makers saying otherwise there could well be an element of addiction – especially since we can’t find any claim that taking Seredyn is intended to completely eradicate anxiety-related symptoms forever afterwards.

As well as that, the makers preface any statistics they offer with descriptions such as in “non-scientific online surveys” and “informal user surveys”. This makes us wonder what the results would be for scientific and formal surveys. Do they have something to hide?

We’re also disturbed by more than one instance on the website where we read: “The proprietary SEREDYN formula can only chase away your worries if you order now.” Does that mean it won’t work if we order it in, say, a week’s time?

So on the basis of these points, we’ve got to reject Seredyn because it doesn’t quite live up to Watchdog’s high standards.

Seredyn Review

Seredyn from BioNeurix has been formulated to provide an experience of increased relaxation, a sense of well-being and reduced worry for at least 4 hours and often up to 8 hours.

Seredyn Facts

  • Interacts with the emotional pathways within the brain to reduce anxiety.
  • Increases the activity of GABA to promote a sense of calm and tranquility.
  • Helps regularize sleep patterns.

Seredyn contains L-Theanine, an amino acid that increases the activity of GABA, a neurotransmitter which stimulates the release of dopamine, thereby increasing a sense of well-being and the confidence that goes with it.

How to Take Seredyn

For daily use: Take one or two capsules up to three times daily.
For occasional “as needed” use: Take 1–3 capsules as needed.
For nighttime worry and restlessness: Take Seredyn as above and consider adding Mellodyn, a natural sleep aid, before bed.

It also contains Passion Flower extract which, although BioNeurix tells us it’s still unknown precisely how it does it, they also tell us it’s been verified to reduce anxiety and promote a more positive outlook.

Seredyn Concerns:

  • Limited information regarding the function of passion flower extract.
  • BioNeutrix suggests combining Seredyn with other products in order to sell more.
  • There is no verified data regarding the effiectiveness of Seredyn.

Clinical studies suggest that Passion Flower is most effective when combined with Valerian, which is why Seredyn also contains standardised Valerian extract to relax both mind and body.

What Does Seredyn Claim To Do?

Seredyn claims to quickly calm down and soothe the worried restless mind.

According to those “informal surveys” its effects last from 4 hours to as long as 8 hours, during which time most people who take it begin to experience increased relaxation, a sense of well-being and reduced worry – starting in as little as thirty minutes.

Does Seredyn Work?

We’re told that 93% of users responding to an online survey do report the feeling of well-being and increased confidence when taking Seredyn by itself. However, when you consider that 93% of the 133 users who chose to participate in that survey represents a very small proportion of the company’s entire customer base, that’s not a very large number of users.

What Are The Ingredients of Seredyn?

Although we’re not told in what kind of proportion, Seredyn’s active ingredients are:

  • L-Theanine: An amino-acid which increases the activity of GABA, a natural neurotransmitter which promotes relaxation, reduces anxiety and which also stimulates the release of dopamine, the neurotransmitter responsible for a sense of well-being and the confidence that comes with it.
  • Passion Flower Extract: Standardised to 4% vitexin, a long-established natural remedy for anxiety and sleep problems.
  • Valerian Extract: Standardised to 0.8% valerenic acid, an effective herbal remedy to calm both mind and body.
  • Niacinamide: A form of niacin with anti-anxiety properties which – unlike regular niacin – doesn’t cause flushing or stress to the liver.
  • Magnesium Taurinate: Combining natural magnesium and the amino acid taurine to calm the mind and support mental well-being.

Seredyn does not contain gluten, soy, casein, yeast, or wheat.

Does Seredyn Have Any Side Effects?

According to users responding to non-scientific online surveys, most of them report experiencing no side effects and of those that did, nearly 4 out of 5 described them as “mild” and, according to the company, those symptoms often disappear.

The most common side effects reported include drowsiness, fatigue, stomach upset and headaches.

Seredyn may also increase the effects of sedative drugs or lower blood pressure.

Before taking Seredyn, talk your doctor if you are taking muscle relaxants, sleep or anxiety medicines, pain medicines, seizure medicines, or other medicines that cause drowsiness. Seredyn may increase the sedative effects of these drugs.

Do not consume excessive quantities of alcohol while taking Seredyn. Seredyn may increase the sedative effects of alcohol.

Do not take Seredyn if you are currently taking a MAOI or have taken a MAOI within the past two weeks.

As with any supplement consult your physician before taking Seredyn with prescription medications.

Are There Any Customer Reviews For Seredyn?

Of course the reviews on the company’s website are all favourable, and who could be surprised by that?

However, we can’t help feeling a little concerned about one reviewer who took the absolute maximum suggested dosage straight off, who said:

But after taking this product before four meetings now (around 45 minutes prior (3 pills)), I can confidently say that I have not experienced any anxiety before presenting and each presentation I have started in a calm, relaxed manner and now my confidence in public speaking is at its highest.

However, looking on the Amazon website gives a different picture: for some, Seredyn didn’t seem to help much, as in:

Didn’t see a difference with my anxiety at all. Would just recommend to see a doctor if you’re having trouble.

It helped me relax some but it did not take away my anxiety, it just has a mild calming effect. My other issue is that it also gave me a mild stomach ache.

I used it several times and it did not do anything. It says it is supposed to be quick acting but I didn’t notice anything even after an hour.

And as for to the company’s advice on their website to pair Seredyn with an ongoing long-term treatment they also produce, as well as their “Seredyn may be able to help you too, but only if you order now,” nudges to go straight to their order page, this Amazon review might just confirm any suspicion that the emphasis is more on extracting dollars from customers than making them feel better in themselves:

The verdict: the main ingredient in this is niacinamide, which is BEYOND cheap to purchase. I already have and use a bottle of that in combination with GABA, which is also very, very cheap. GABA gives you more of a tranquilliser feeling and helps you sleep, along with varying other benefits per user. Niacinamide + GABA = great night’s sleep and better mental health for less than but no more than $1 a week. Seredyn would have you going through a bottle a week looking for relief.

Does Seredyn Offer a Money-Back Guarantee?

Well, they do guarantee your privacy and the quality of their ingredients, but not delivery timings or “specific results for all people”.

What they do tell us, though is: “Please keep in mind that every person is different and will respond differently to supplementation with Seredyn,’ and along those lines customers are entitled to return up to one opened bottle (and enclose $10 for a processing fee).

Any other unopened bottles can be returned within 60 days of shipment for a refund, but shipping is at your own cost.

Refills shipped automatically as part of the company’s autoship program can also be returned, but you’ve only got 20 days in which to do so.

Where Can I Buy Seredyn?

The Seredyn website urges you to order online through their own order page, with payments handled by most major credit cards and PayPal.

Ordering by mail is also an option with a personal check, money order or credit card details.

It’s also available on the Amazon marketplace and on eBay. It might be available at your local vitamin or health food store, but call first to check.

Is there any chance of a free trial before handing over your hard-earned money? Sadly at present, no – and it doesn’t look like there’s going to be one in the future, either.
