Why You Feel Like Rubbish 
(It's Not All in Your Head)

You've tried the meditation apps. The gratitude journals. The expensive therapy. And maybe they helped a bit. But that heavy, foggy, "why am I so tired all the time" feeling? Still there.

 

Here's what nobody told you: your mental health isn't just about what's happening between your ears. There's a direct hotline between your gut and your brain—and for most of us, the signal's been scrambled for years.

"I'd been in therapy for two years. It helped, but something was still off. Turns out my gut was sending stress signals 24/7. Once I addressed that, everything shifted."

This isn't about replacing your mental health support. It's about filling in a massive blind spot that most approaches completely ignore.

the gut-brain axis: your body's secret communication system

Your gut and brain are constantly texting each other. Literally. They're connected by the vagus nerve—the longest nerve in your body—and they exchange messages 24/7.

 

When your gut bacteria are out of balance, they send stress signals to your brain. Your brain responds with anxiety, low mood, brain fog. It's a two-way street, and most of us have been ignoring half of it.

 

The kicker? Your gut produces more neurotransmitters than your brain does. 95% of your serotonin (the "happy chemical") is made in your gut. Not your head. Your gut.

The research is clear: your gut health directly impacts your mood, energy, and mental clarity. Ready to see what's possible?

How It Actually Works

The Vagus Nerve: Your Body's Information Highway

The vagus nerve is like a super-fast broadband connection between your gut and brain. It carries information in both directions, but here's the surprising part: about 80% of the signals travel UP from gut to brain, not the other way around.

 

When your gut bacteria are thriving, they produce short-chain fatty acids and neurotransmitters that send "all good" signals to your brain. When they're struggling, the signals are more like "PANIC STATIONS."

Neurotransmitters: Made in Your Gut

Serotonin, dopamine, GABA—the chemicals that regulate your mood, motivation, and calm? Your gut bacteria play a massive role in producing them. When your microbiome is out of whack, production drops. And you feel it.

 

This is why antidepressants don't work for everyone. If your gut isn't making the raw materials, your brain can't use them—no matter what medication you're on.

Inflammation: The Silent Mood Killer

When your gut barrier is compromised (hello, stress, processed food, and antibiotics), inflammatory compounds leak into your bloodstream. They cross the blood-brain barrier and trigger neuroinflammation.

 

The result? Brain fog, fatigue, low mood, anxiety. Your brain is literally inflamed. And no amount of positive thinking will fix an inflamed brain.

Sleep, Stress, and the Vicious Cycle

Poor gut health disrupts sleep. Poor sleep disrupts gut health. It's a vicious cycle that leaves you exhausted, wired, and unable to recover.

 

Your gut bacteria follow circadian rhythms too. When those rhythms are disrupted (hello, 3am doomscrolling), your microbiome suffers—and so does your mental clarity the next day.

the research backing this up

Probiotics and Depression

A 2019 meta-analysis of 34 controlled trials found that probiotics significantly reduced depressive symptoms, with effects comparable to some antidepressants.

 

— Journal of Affective Disorders, 2019

Gut Bacteria and Anxiety

Patients with anxiety disorders show significantly different gut microbiome compositions compared to healthy controls, with lower diversity and specific bacterial imbalances.

 

— General Psychiatry, 2019

The Second Brain

Your enteric nervous system contains more neurons than your spinal cord and can operate independently of your brain—earning it the nickname "the second brain."

 

— Johns Hopkins Medicine

Inflammation and Mental Health

Chronic low-grade inflammation from gut dysbiosis is now recognized as a key factor in depression, with anti-inflammatory interventions showing promise as treatments.

your top questions, answered

If you are facing any of the following struggle in you daily life,  then we have the solution for you.

  • About Our Products

  • Ordering & Shipping

  • Returns & Refunds

  • Using the Products

Will this actually work for me?

Honestly? We can't promise anything because everyone's different. What we can tell you:

  • 89% of our customers report noticeable improvements within 6 weeks
  • The ingredients are backed by clinical research (we link to the studies on our science page)
  • If it doesn't work for you, you get your money back within 90 days

Most people who don't see results either stop too early (give it at least 4 weeks) or don't take them consistently. Use the app to track your symptoms - you might be improving without realising it.

What's the difference between all your products?

Here's the quick breakdown:

  • Gut-Brain Duo: The foundation. Probiotics + prebiotics for gut health. Start here if you're new.
  • Neuro Balance: Stress and anxiety support. Ashwagandha, L-Theanine, B vitamins. Great if you're constantly on edge.
  • CleanseFlow: Digestive support. Helps with bloating, irregularity, general gut discomfort.
  • MindMoss: Cognitive support. Lion's Mane + adaptogens for brain fog and focus.
  • The Ultimate Kit: All of the above. Best value, complete system.

Not sure where to start? The Gut-Brain Duo is our most popular starter product. Or just go for the kit if you want to address everything at once.

Are there any side effects?

Most people don't experience any side effects. However, in the first week some people notice:

  • Mild bloating (normal - your gut is adjusting to new bacteria)
  • Changes in digestion (usually temporary, settles after 5-7 days)
  • Slight changes in energy levels

These are usually signs that the products are working. If anything feels concerning, stop taking them and chat with us or your GP.

 

Important: If you're pregnant, breastfeeding, on medication, or have a medical condition, check with your doctor first. We're not trying to replace medical advice.

Are your products vegan/vegetarian?

All our products are vegetarian-friendly. MindMoss and Neuro Balance are fully vegan. The Gut-Brain Duo and CleanseFlow capsules use vegetable cellulose, but some probiotic strains may be cultured using dairy-derived ingredients.

If you have specific dietary requirements, check the full ingredients list on each product page or drop us a message.

Can I take these with my other supplements/medications?

Our products are generally safe to take alongside other supplements. However, if you're on medication - especially:

  • Blood thinners
  • Thyroid medication
  • Antidepressants or anti-anxiety medication
  • Immunosuppressants

Please check with your doctor or pharmacist first. Some ingredients (particularly Ashwagandha in Neuro Balance) can interact with certain medications.

We're not doctors, and we'd rather you check than have any issues.

How long does shipping take?

UK Orders:

  • Standard: 3-5 working days (free over £40)
  • Express: 1-2 working days (£4.99)

International Orders:

  • Europe: 5-7 working days (£6.99)
  • Rest of World: 7-14 working days (£9.99)

You'll get a tracking number as soon as your order ships. If something seems delayed, just contact us and we'll sort it out.

Do you do subscriptions?

Yes! Subscribe & save gets you 20% off every order plus free shipping. You can:

  • Choose your delivery frequency (every 30, 60, or 90 days)
  • Skip or pause anytime from your account
  • Cancel whenever you want - no contracts, no guilt trips

Most customers find monthly delivery works best since each pouch is a 30-day supply.

My order hasn't arrived - what do I do?

First, check your tracking link (we email it when your order ships). Sometimes orders get stuck at the local depot or need a signature.

If your tracking shows "delivered" but you haven't received it, check with neighbours and any safe spots around your property.

Still nothing? Email us at support@symflory.com with your order number and we'll either track it down or send a replacement. We won't leave you hanging.

What's your refund policy?

90-Day Money-Back Guarantee - no fine print, no hassle.

 

If you've been taking the products consistently for at least 4 weeks and haven't noticed any improvement, just email us and we'll refund your purchase. Yes, even if the pouch is empty.

 

We ask that you've actually given it a fair trial (4+ weeks, consistent daily use) because gut health takes time. But we won't interrogate you - if it didn't work for you, that's reason enough.

 

How to request a refund: Email support@symflory.com with your order number and a brief note about your experience. We process refunds within 5 working days.

Can I return unopened products?

Absolutely. Unopened products in original packaging can be returned within 30 days for a full refund. Just email us first so we can send you return instructions.

We'll refund you once we receive the items back. Return shipping is on you unless we made an error with your order.

When should I take them?

Morning with breakfast is the sweet spot for most people. The food helps with absorption and protects the probiotics through your stomach acid.

Consistency matters more than perfect timing. Set a reminder on your phone if needed. Taking them at random times is less effective than taking them at the same time every day.

 

See our complete How to Use guide for product-specific timing recommendations.

How long before I see results?

Honestly, it varies. But here's what we typically see:

  • Week 1-2: Some people notice improved digestion or sleep. Others feel nothing yet.
  • Week 3-4: Most people start noticing changes - reduced bloating, better energy, improved mood.
  • Week 5-6: This is where significant improvements usually happen.
  • Week 8+: Benefits continue to compound as your gut microbiome rebalances.

If you haven't noticed anything after 6-8 weeks of consistent use, you're probably in the minority who don't respond to these ingredients - and that's what our guarantee is for.

What's the app for and do I need it?

The app is free and completely optional, but we really recommend it because:

  • It helps you track your symptoms and see patterns you'd miss otherwise
  • Many people don't notice gradual improvements without tracking
  • It shows you food-mood correlations (turns out your gut knows things)
  • It takes literally 30 seconds a day

You don't NEED it - the supplements work regardless. But people who track tend to stick with the routine longer and see better results.

Can I take more than the recommended dose?

We don't recommend it. The doses are calibrated based on clinical research - more isn't necessarily better and can sometimes cause digestive upset.

If you're not seeing results at the standard dose, the answer usually isn't "take more" - it's "give it more time" or "this might not be the right fit for you."
