StressLess Oral Spray is a sublingual mouth spray from Dutch brand Foodsporen that combines reishi mushroom extract, L-theanine, ashwagandha, vitamin B6 and B12 in a 5-spray daily dose. Built for people who'd rather not pop a capsule with a glass of water at their desk — you spray, you swallow, you carry on.
Why we stock the Foodsporen StressLess spray
Most stress supplements come as capsules the size of a small almond. Foodsporen went the other route — a sublingual spray that sits under the tongue for fast absorption through the oral mucosa. According to a 2021 review on intranasal and sublingual vitamin B12 delivery (PMC8001893), this route bypasses some of the absorption losses you get with swallowed tablets, particularly for B12.
The formula leans on three botanicals that get cited together a lot in adaptogen literature. Reishi (Ganoderma lucidum) is the headline — Foodsporen calls it "the king of mushrooms" and it's been a staple of East Asian herbal traditions for centuries. L-theanine, the amino acid you'll recognise from green tea, is added to pair with the reishi. Ashwagandha (Withania somnifera) brings the Ayurvedic angle. According to a 2024 review on Withania somnifera and Bacopa monnieri (PMC11643393), adaptogens like ashwagandha have been studied for their effects on oxidative stress pathways including MAPK and PI3K/Akt signalling.
None of these compounds have an approved EFSA health claim, so we can't tell you it'll fix your Sunday-night dread. What we can say: it's a clean formulation from a Dutch brand we've worked with, the spray format is genuinely easier to use than a capsule, and the bottle fits in a jacket pocket.
What's actually in the bottle
Five active ingredients, no filler theatrics. Here's the rundown.
| Ingredient | Role in the formula |
|---|---|
| Reishi extract (Ganoderma lucidum) | Lead botanical, traditionally used in East Asian herbal practice |
| L-theanine | Amino acid found naturally in green tea; paired with reishi |
| Ashwagandha (Withania somnifera) | Adaptogenic herb from Ayurvedic tradition |
| Vitamin B6 | Contributes to normal psychological function (EFSA-approved claim) |
| Vitamin B12 | Contributes to normal energy-yielding metabolism (EFSA-approved claim) |
The B6 and B12 are the only ingredients with approved EFSA wording, which is why we mention those benefits and not the others.
Who StressLess is for
StressLess is built for people who want a daily ritual that doesn't feel like medicine. Five sprays in the morning or before bed, done. It's the right pick if:
- You travel often and want something pocket-sized — capsule bottles are a hassle through airport security
- You don't get on with swallowing tablets (a lot of customers don't, and that's fine)
- You like the idea of pairing reishi and ashwagandha but don't want to source two separate products
- You want a clean, vegan-friendly formula without the sweetener-and-flavouring soup most sprays come with
If you're after a higher-dose ashwagandha specifically, a standalone KSM-66 capsule will get you more milligrams per serving. StressLess is a combination formula — broad rather than deep.
How to use the StressLess spray
- Take the cap off and shake the bottle well — the botanicals settle, so this matters.
- First time using it? Prime the pump by pressing it a few times until liquid actually comes out.
- Spray 5 full sprays directly into your mouth, ideally under the tongue.
- Hold the liquid in your mouth for 20–30 seconds before swallowing — sublingual absorption is the whole point of this format.
- Rinse the nozzle under cold water afterwards and put the cap back on. Stops it gunking up.
One dose per day. Foodsporen's instructions say 5 sprays daily — don't stack it on top of other adaptogen blends without checking what's in them, since you'll likely double up on ashwagandha.
Honest limitations
A few things worth flagging before you order. First — taste. Sublingual sprays with mushroom extracts are not winning any flavour awards. It's earthy, slightly bitter, and the ashwagandha gives it a distinctive note some people find odd at first. After a week you stop noticing.
Second — this isn't a fast-acting sedative. It's not GABA, it's not valerian, it's not going to knock you out 20 minutes after spraying. Adaptogenic formulas like this are typically studied over weeks of consistent use, not single doses. If you want something for acute, in-the-moment stress, a CBD oil or a chamomile tea will probably feel more immediate.
Third — food supplements don't replace a proper diet, sleep, and the boring stuff that actually moves the needle on stress. If you're sleeping four hours a night and living on coffee, no spray will out-formula that.
Pairs well with our reishi tincture if you want to deepen the mushroom side of your stack, or with a magnesium supplement for the sleep-and-recovery angle. If you'd rather have your adaptogens in tea form, the Foodsporen mushroom blends from the same brand work as a daytime alternative.
From our counter
We get the same question a lot: "what's the difference between this and just taking ashwagandha capsules?" The honest answer is — convenience and combination. A standalone KSM-66 capsule will give you more ashwagandha per serving. StressLess gives you a smaller dose alongside reishi, L-theanine, and B-vitamins in a format you can use without water. If you're already taking three other supplements, the spray is the path of least resistance. If you want maximum ashwagandha, buy ashwagandha.
Frequently Asked Questions
How long until I notice anything from StressLess?
Adaptogens like reishi and ashwagandha are typically studied over 4–8 weeks of consistent daily use, not as single-dose interventions. Don't expect the first spray to do much — give it a couple of weeks of daily use before you decide.
Can I take StressLess with other supplements?
Generally yes, but check what's in your other supplements first. A lot of "calm" or "sleep" formulas already contain ashwagandha or L-theanine, and you don't want to double-dose. If you're on prescription medication — particularly thyroid, sedatives, or blood pressure meds — talk to your doctor first.
Is StressLess vegan?
Yes, all five active ingredients are plant-based or synthesised. Reishi and ashwagandha are botanicals, L-theanine is amino-acid based, and the B-vitamins in this formula are produced through fermentation rather than animal sources.
Why a spray instead of capsules?
Sublingual absorption — the oral mucosa is rich in blood vessels, so some compounds can be absorbed faster than via the gut. It's also genuinely easier to use: no water needed, fits in a pocket, and works for people who struggle with capsules.
Can I use it more than once a day?
Foodsporen's recommended dose is 5 sprays once daily. We'd stick to that — there's no benefit to spraying more, and you'll just burn through the bottle faster. Consistency matters more than dose with adaptogenic formulas.
Does StressLess contain caffeine or anything stimulating?
No caffeine, no stimulants. The formula is built around adaptogens and amino acids — it's designed to take the edge off rather than wake you up. You can use it day or night without affecting sleep.
