"ok so I never write reviews but here we go. I've had sleep issues since my second kid (he's 6 now lol so… it's been a while). Tried melatonin, tried the sleepy girl mocktail thing from tiktok, tried no screens after 9 which lasted exactly 2 days. This one actually stayed in my routine because it just tastes good?? Like a raspberry lemonade. I drink it around 9 while packing lunches. I fall asleep faster but the bigger thing is I stopped lying there with my mind racing. My husband ordered his own box because he kept stealing sips of mine."

"Bought it after seeing an ad and fully expected to return it. I'm a teacher with 3 kids, my stress is not going anywhere 😅 What I noticed after about 2 weeks, the end of the day doesn't wreck me the same way. I still get stressed obviously. But I'm not snapping at everyone by 6pm and then feeling guilty about it at midnight. That alone is worth it for me. Also tip: it dissolves way better in cold water, don't use warm."

"Almost gave up on this. The first week I felt absolutely nothing and I was annoyed because it's not the cheapest thing I've bought. Kept going because I'd already paid for the month. Then somewhere in week 2 it clicked. I'm a 3am waker and I sleep through most nights now, which hasn't happened in over a year. 4 stars because of the slow start and because the taste is slightly sweet for me, I just use extra water. Would definitely still buy again."

"ngl I ordered this half asleep at 2am. which is ironic. no regrets though. I bought it for sleep but the thing I didn't expect, I used to hit a wall every afternoon and inhale whatever sugar was closest. that's calmed down a lot?? my coworker took this pic because she says I've been 'suspiciously pleasant' lately lol. only complaint is there's one flavor. I would kill for a peach one. please make a peach one."

"I'm the person who reads every label, so believe me when I say I did my homework before buying. Most ashwagandha products are 120-300mg and won't tell you the source. This is 600mg KSM-66 and it's printed right on the bag. That's why I picked it over cheaper ones. About 7 weeks in now. Sleeping deeper, less puffy in the morning, and I've stopped needing a nap to survive the weekend. It's not cheap. But neither were the five things that didn't work."

"My friend Kathy had been going on about this stuff since spring. I finally tried it at her house mostly to get her to stop talking about it. Well. I've now been ordering it for 3 months, so you can imagine how that conversation went. I take it after dinner instead of my usual glass of wine, didn't plan that, it just sort of happened. Sleeping better, less bloated in the mornings, and my daughter says I'm less cranky. Which was rude. But fair."

"I don't know how to write this without sounding dramatic. For a couple of years I just felt… flat. Not sick, not depressed exactly. Just running on empty and used to it. This was one of maybe ten things I tried and it's the one that stuck, partly because the evening drink is a genuinely nice little moment for myself. 3 months in, I'm sleeping properly and I feel more like me. My husband noticed before I said anything. Anyway. If you're on the fence, it's the real deal."

Not gonna lie, I only bought this because the ad followed me around for two weeks and I caved. But it's the first supplement I've ever actually finished the bag of. I have it around 9pm, tastes like raspberry lemonade, zero effort. I'm calmer in the evenings and I fall asleep faster — my Fitbit says my deep sleep is up since I started. Expected nothing. Currently on my third bag.

Nucleva™ Cortisol Balance Drink

$59.90

Most stress supplements hide behind "proprietary blends" — a legal way to underdose every ingredient without telling you. We do the opposite: every dose is printed on the pack.

🌿 600mg KSM-66® Ashwagandha

🍵 L-Theanine

✨ Magnesium Bisglycinate

☀️ Vitamin D3

Why it matters: in a 60-day randomized controlled trial, 600mg of KSM-66 ashwagandha per day — the exact dose in every Nucleva sachet — reduced serum cortisol by 27.9%.* Most competitors use 125-300mg and hope you won't check.

Zero sugar. Zero caffeine. Nothing to swallow — it's a raspberry-lemon drink you'll actually look forward to.

When stress and broken sleep keep your stress hormone elevated in the evening, your body stays in "survival mode" — and the cycle feeds itself: stress disrupts sleep, poor sleep raises stress. That's the Cortisol Loop. Here's how the evening ritual helps break it:

The Evening Wind-Down — One sachet in cold water after dinner. KSM-66 and L-theanine support a calm, healthy stress response — a settled feeling, without sedation.

Deeper, More Restful Sleep — Magnesium bisglycinate supports muscle relaxation and restful sleep, so nights feel less broken and mornings less heavy.

Out of Survival Mode — With calmer evenings and better sleep, night after night, many women report less morning puffiness and fewer stress-driven sugar cravings over the following weeks.

The honest timeline: most women feel the calm the first evening. Sleep tends to improve over the first 1-2 weeks. The rest builds over weeks 3-8 — that's why the 90-day supply is our most popular option. Individual results vary.

You've probably tried things that promised the world and delivered nothing. So we made this as simple as possible:

Try Nucleva for 90 full nights. If you don't feel calmer in the evenings and more rested in the mornings, we refund you — even if you've used every last sachet. No "unopened products only" fine print. No hoops.

No questions asked — one email is enough.

Real human support — write to us anytime, a person answers.

We take the risk so you don't have to. You love it, or you pay nothing.

Processing: 24 business hours

Delivery time: orders typically arrive within 5 to 8 business days. Most packages land well before the 8-day mark — we quote the longer window to stay on the safe side.

Tracking included — you receive a tracking number by email as soon as your order ships.

Questions? contact@nucleva.com

What if it's not your diet — but your stress hormone working against you?

You eat well. You do everything "right". And yet, you feel puffy in the morning, wired at night, drained by 4pm. The silent culprit is often cortisol, the stress hormone.

When stress and broken sleep keep it elevated, the body flips into "survival mode": it holds onto water, spikes sugar cravings and breaks your sleep which creates more stress. That's the Cortisol Loop. And it feeds itself, night after night.

Women who feel like their body changed almost overnight especially after 40. The ones who are "wired but tired": exhausted all day, wide awake at 11pm. Who wake at 3am for no reason. Who've tried magnesium alone, melatonin, cutting carbs and are done guessing.

It's probably not for you if you expect a magic fix in three days. The calm comes the first evenings the rest builds over weeks. That's how it works.

Four calming actives, at full doses, printed on the pack: 600mg KSM-66® ashwagandha (the exact dose used in the published research), L-theanine for calm without drowsiness, magnesium bisglycinate the form your body actually absorbs and vitamin D3.

No proprietary blend. No hidden amounts. Zero sugar, zero caffeine just a raspberry-lemon drink you'll look forward to every evening.

In a 60-day randomized, double-blind, placebo-controlled trial, 600mg of KSM-66 ashwagandha per day reduced serum cortisol by 27.9% and significantly improved perceived stress scores (Chandrasekhar et al., 2012).

Most supplements cite studies like this one then include a fraction of the studied dose. Nucleva uses the full 600mg. That's the difference between borrowing science and actually applying it.*

Feel like yourself again — one evening at a time

Stop waiting for the stress to magically disappear. With Nucleva, you don't have to overhaul your life to start feeling different — you just have to mix one sachet into cold water, tonight.

Its four calming actives at full clinical doses support a calm stress response and deeper, more restful sleep — and as the nights add up, many women notice less morning puffiness and fewer sugar cravings. The loop breaks the way it formed: night after night.

"I didn't change anything else about my routine. Three weeks in, I stopped waking up puffy and I'm sleeping through the night. It's the only habit I've actually kept."

FAQ

Who is Seryova for?

Seryova is for women who want to flatten their belly, eliminate love handles, boost their confidence, burn calories passively, and feel more comfortable in their own skin every single day.

How does the Seryova Shapova camisole work?

Shapova is made with a patented 3D micro-massage fabric that actively works with your body throughout the day. Its thermo-active fibers boost circulation, trigger thermogenesis to burn calories passively, and deliver targeted compression to smooth the belly and slim the waist. Worn regularly, it visibly reshapes the silhouette.

How long before I see a difference?

You'll feel the difference from the very first wear — flatter belly, smoother silhouette instantly. For lasting results, most customers notice visible changes within 30 days of daily wear.

What if the size doesn't fit?

No worries. If the size doesn't work, contact us at contact@seryova.com and we'll arrange an exchange right away.

What are the shipping times?

Orders are processed within 24 hours.

We offer free delivery within 5 to 8 business days across the US, UK, Canada, Australia, New Zealand and Ireland. Most orders arrive before the 8-business-day mark, but we prefer to give a safe estimate just in case.

A tracking number will be sent to you by email once your order is shipped.

Is the Shapova machine washable?

Yes, but we recommend washing on a cold/gentle cycle to preserve the fabric, compression, and thermogenic properties.

What is the Shapova made of?

80% nylon — 20% elastane.

Visible results from day one

I had my doubts but the results are real. My belly is genuinely smoothed, nothing spilling over. I wear it every day at the office under my dresses and nobody suspects a thing. Incredible!!!

I wasn't sure about my size before ordering, sent a message and got a reply in under 2 hours with precise advice. They steered me toward M - perfect fit. Great product and great team behind it. Rare these days.

Size S perfect for 115 lbs

I followed the size guide and made the right call. Silhouette really smoothed, nothing spilling at the waist. Under a fitted pair of jeans it's perfect.

Invisible under a white dress

That was my ultimate test. Fitted white dress for a wedding - zero visible seam, zero muffin top. All my friends asked me what my secret was.

The product itself is genuinely great. Perfect hold, invisible under dark clothing. But under a very light beige blouse you can slightly see the black. Waiting for a nude version. For now I use it with darker outfits and I'm happy.

I ordered the wrong size, reached out and the exchange was done in 2 days. The camisole itself is excellent - gentle compression, silhouette visibly smoothed from the moment you put it on.

I know it's the compression but seeing the difference in the mirror does something to you. I feel lighter, more confident. I ordered a second one in beige.
