Description

Solumos is a single-ingredient food supplement: Rhodiola rosea root extract at 400 mg per capsule, standardised to exactly 3% rosavins and 1% salidroside. 30 capsules per bottle — a one-a-day, 30-day supply. No blends, no fillers, no flow agents.

Why Solumos Rhodiola?

Published Rhodiola research used 300–600 mg of standardised extract. Many high-street bottles contain 50–100 mg, never state their marker compounds — and were often never standardised at all. Solumos gives you 400 mg standardised to exactly the 3% / 1% ratio used in the studies — stated on the label, verified by a third-party lab.

Ingredients

Rhodiola rosea root extract — 400 mg (of which rosavins 12 mg, salidroside 4 mg). Capsule shell: vegan HPMC. That's the whole label. No gluten, soy, or dairy.

Recommended use

One capsule daily with breakfast — taking it with food supports the absorption of Rhodiola's fat-soluble actives. Adaptogens are traditionally taken consistently, so give it a fair run of 6–8 weeks. Do not exceed the stated daily intake. If you take prescription medication, or are pregnant or breastfeeding, speak with your GP or pharmacist first.

Do we offer a guarantee?

Yes — a 90-day money-back guarantee. Finish the bottle if you like, then email us. Empty bottles accepted, refunds within 5 working days, no back-and-forth.

Why the 2pm Crash, the 3am Wake-Ups & That Puffy, Wired-But-Tired Feeling Show Up Together

If more than one of these feels familiar, it's not discipline — and it's not age:

You wake up tired and puffy after a full eight hours — like sleep isn't doing its job any more.
You feel bloated and heavier by mid-afternoon — even on days you're doing everything right.
Brain fog thick enough to lose words mid-sentence — and you're on edge over small things that never used to touch you.
The 2pm crash hits like clockwork — and coffee or sugar is the only way through.
Your body is done but your head won't stop — and at 3am you're wide awake, mind racing.

Here's the part nobody points out:

They rarely show up one at a time. Because they're not five separate problems — they're one signal, stuck in the 'on' position.

The Stress Loop You've Been Stuck In

The Signal
How It Feeds the Loop
Waking up unrefreshed
Starts the day on borrowed energy — so the crash arrives earlier and hits harder.
The 2pm slump
Invites the second and third coffee — the ones that keep your stress hormones on duty into the evening.
Running on caffeine and sugar
Keeps your system in 'fight or flight' long past closing time — so you're wired when you finally lie down.
Light, restless sleep
The overnight reset never completes — and you loop straight back into waking up tired.
That heavy, on-edge feeling
Builds a little more each time the loop repeats — until it feels normal. It isn't.

Meet Cortisol — the Stress Signal That Won't Switch Off

Cortisol is your body's main stress hormone — brilliant in short bursts, exhausting when it never stands down. Think of your energy like a daily budget: every demand — work, screens, short nights, skipped breaks — spends from it, and every good night's rest pays back in. Cortisol is the signal deciding which mode you're in.

When the signal switches off on time, you don't even notice it:

  • Cortisol rises briefly in the morning to wake you — energy climbs, then settles by evening.
  • It drops at night, so a demanding day is followed by a night that resets it.
  • You feel steady without having to think about it.

But after months of modern stress — late nights, deadlines, constant pings, one more coffee — the signal stops standing down. Your body stays in 'fight or flight', and everything that runs on 'rest and recover' gets pushed down the queue.

  • The signal stops switching off — the overnight reset never quite completes.
  • Each morning starts a little lower than the last.
  • Quick fixes — more coffee, more sugar — push the signal higher still.
  • 'Tired but wired' quietly becomes the default.

And it compounds. Day after day. Week after week.

  • That's why mornings feel like wading through sand.
  • That's why the crash arrives before lunch is finished.
  • That's why quiet evenings still feel loud.
  • That's why sleep stopped feeling like rest.
  • That's why 'just pushing through' stopped working.

Why the 400 mg Dose Changes Everything

Most Rhodiola on the shelf contains 50–100 mg — a fraction of the 300–600 mg the published trials used. Most never state their rosavin percentage at all, and some hide even less behind a 'proprietary blend'. You feel nothing — and conclude Rhodiola doesn't work.

Solumos is 400 mg of pure Rhodiola rosea extract per capsule, standardised to exactly 3% rosavins and 1% salidroside — the same concentration specified in peer-reviewed human trials.

At this dose, here's exactly what's in your capsule — stated, not implied:

  • A dose inside the 300–600 mg range used across published Rhodiola trials
  • 12 mg rosavins and 4 mg salidroside per capsule — printed on the label, not implied
  • The full daily amount in one capsule — not spread across six
  • The exact 3% / 1% extract-to-marker ratio the trials specified
  • A third-party lab certificate behind every batch
  • No blend maths — no 'proprietary complex' hiding the numbers

One clean ingredient. No fillers. No blends. No distractions. Just 400 mg of one of the most-studied adaptogens on earth — at the dose the studies actually used.

Mornings finally feel like mine

I'm 61 and had started to accept waking up flat and puffy before the day even began. Six weeks in, getting up feels less like a chore. Easy to swallow, no aftertaste, and the label tells you exactly what's inside.

Down from four coffees to one

The 2pm slump was running my diary. I gave this an honest eight weeks like they suggest. The afternoon wall isn't gone every single day, but most days I sail straight through where I used to crash.

Sarah P.Verified purchase

No more 3am ceiling-staring

I used to be switched on until midnight and wide awake again at 3am, mind racing. I find I wind down much easier now and mostly sleep straight through. Can't promise it's the capsules alone, but the timing lines up and I'm not changing anything.

Check the label on your old bottle

I'd taken Rhodiola before and felt nothing — then found out it was 75mg with no rosavin percentage listed anywhere. This is 400mg standardised to 3% and 1%, printed right on the front. Night and day in how I feel about what I'm paying for.

Sceptic, mostly converted

Nothing for the first month, which nearly lost me. Weeks five and six changed my mind. Knocking a star off for the wait, but I've already reordered, so make of that what you will.

Janet M.Verified purchase

Small things stopped rattling me

I noticed it in traffic, of all places. Less snappy, steadier through a busy day at work — and I'm not the one hunting for a cardigan in a warm office any more. My daughter has started taking it now too.

Tom R.Verified purchase

One clean ingredient, as advertised

I emailed asking for the lab certificate before ordering and they sent it the same day. One ingredient, the dose on the front, nothing hidden. That alone tells you what kind of company this is.

Subscription is effortless

Turns up every month without me thinking about it, and it was easy to pause when we went away. UK delivery took two days. This is how it should work everywhere.

The guarantee made it an easy try

I only bought it because of the 90-day promise, fully expecting to send it back. I didn't. Four stars because I'd love a bigger bottle option.

Bought for my wife — now we both take it

She noticed a difference in her afternoons first. Two months in I stopped pinching hers and ordered the Buy 2 Get 1 Free pack. Does what the label says and nothing it doesn't.

Before you ask

Questions people ask us

How is this different from a Rhodiola I've tried before?

Almost always, the difference is dose and standardisation. Published research on Rhodiola uses 300–600 mg of standardised extract; many high-street bottles contain 50–100 mg. If your last Rhodiola did nothing, check its label — if there's no rosavin percentage on it, you weren't getting the studied extract. Solumos is 400 mg per serving, standardised to exactly 3% rosavins and 1% salidroside — the marker compounds used in the studies.

How do I take it?

One capsule daily with breakfast — taking it with food supports the absorption of the fat-soluble actives. Adaptogens are traditionally taken consistently; many people take Rhodiola daily for at least 8 weeks to give it a fair run.

Is it vegan and gluten-free?

Yes to both. Plant-derived cellulose capsule, no gluten, no soy, no dairy.

Where is it made?

Manufactured in the United Kingdom in a GMP-audited facility. Every batch is third-party tested for identity, purity, and contaminants before it ships.

How does Rhodiola compare to ashwagandha?

Different plants, different traditions. Ashwagandha is the Ayurvedic wind-down herb; Rhodiola is the Scandinavian and Russian adaptogen traditionally taken for demanding days. Plenty of our customers arrive here after ashwagandha didn't move the needle for them. They can be taken separately or in rotation — speak to a practitioner for a stack that fits you.

Can I take it with other supplements or medication?

Rhodiola is generally compatible with common supplements. If you take prescription medicine — particularly for mood, thyroid, blood pressure, or if you're pregnant or breastfeeding — speak with your GP or pharmacist before starting.

What if it isn't for me?

90-day money-back guarantee. Finish the bottle if you like, then email us. Empty bottles accepted. Refunds within 5 working days.

Does it contain black pepper extract (BioPerine)?

No — and that's deliberate. Solumos is one clean ingredient: 400 mg of standardised Rhodiola rosea extract and a vegan capsule, nothing else. Instead of adding extras to the label, we recommend taking your capsule with breakfast — taking Rhodiola with food supports the absorption of its fat-soluble actives.
