Best Cortisol Supplements: How the Leading Options Compare
Published 5 October 202610 min read
If you’re shopping for a cortisol supplement, you’ve probably got three tabs open and a magnesium already in the cupboard. This guide puts four options side by side: what’s in each one, how much, how you take it, and what happens if it doesn’t suit you.
One Reddit user summed up the shelf: “Some of it maybe took the edge off, but the wakeups are still bang on schedule.” So we’ve compared what’s actually on each label.
The short answer
Four Options, One Question: How Many Jobs Does the Label Cover?
Our featured pick: Jevi Nervous System. Six ingredients in two capsules a day, every dose printed, and a 60-day money-back guarantee on your first order. It lists more ingredients than any other product in this comparison.
The others in this guide, A to Z: BioRoot Labs Magnesium Glycinate 3 In 1, Moon Juice SuperYou, Nello Supercalm. Each one does a narrower job, and each is a fair pick for the right person. Details below.

How this guide was put together
What We Compared, and Where the Facts Come From
This guide is published by Jevi. We haven’t run a lab test or a trial on any product here, so nothing is ranked by “results”.
What we did: we read each product’s own page on 5 October 2026 and wrote down what the brand itself lists. Format, ingredients and doses, the daily serving, and the money-back guarantee if one is shown. Where a page didn’t say something, the table says “Not listed”.
Brands change formulas and offers. Check the label before you buy, and talk to your doctor or pharmacist if you take medication.

5 Things to Check Before You Buy a Cortisol Supplement
Most of this is on the back of the bottle. It takes two minutes, and it tells you more than the front.
1Every dose on the label
A label that lists each ingredient with its milligrams lets you see how much you’re getting. A “proprietary blend” gives you one total and no breakdown.
Jevi: every ingredient and exact dose listed

How many jobs the formula covers
Stress shows up in different places: your mood, your focus, tension in your body, your sleep, the cortisol rhythm through the day. Most single-ingredient products cover one of those. It’s one reason a product can “help a bit” and stop there. One Reddit user put a number on it: “magnesium helps 7%”.
If magnesium alone helped a bit, that was the product doing the job it’s listed for. You didn’t do anything wrong.
Jevi: six ingredients, six listed jobs
- 3
Whether it suits the daytime
Some products are built for the last hour before bed and can leave you “groggy the next day”. If your stress starts at 2pm, look for ingredients listed for calm without drowsiness. One Jevi customer, Margaret: “This unfamiliar sense of calm and level-headedness was just there.”
Jevi: calm “without knocking you out”†
- 4
How you take it
Capsules, gummies or a drink mix. How many a day, and when. The routine that works is the one you’ll still be doing in week eight.
Jevi: 2 capsules once a day
- 5
The guarantee and the price per day
These products are meant to be taken daily for weeks, so a guarantee shorter than a month or two doesn’t give you much time to decide. Work out the price per day as well as per bottle.

Jevi Nervous SystemJevi Nervous System: Six Ingredients, Two Capsules a Day
- 6 ingredients
- 2 capsules a day
- 60-day guarantee
Jevi Nervous System is a cortisol and nervous-system formula that used to be sold as Corti-Help. Same formula, new name and label. Jevi describes it as a 6-pathway cortisol formula “designed to support your nervous system, healthy cortisol levels and daily stress recovery, without knocking you out.”†
Here’s what’s in two capsules:
Job (from Jevi’s label)
Long-term cortisol support†
Ashwagandha root extract
250 mg · 4% withanolides
Gut-brain stress support†
Psychobiotic probiotic blend
10 billion CFU · L. helveticus 7B, B. longum 3B
Mood support†
Saffron extract
30 mg · 5% safranal
Takes the edge off stress†
Sceletium tortuosum
20 mg · 5% mesembrine-type alkaloids
Calm focus without drowsiness†
L-theanine
400 mg
Physical tension and wind-down support†
Magnesium glycinate
200 mg
That’s six ingredients against four at most for the others in this guide. Three of the six (saffron, sceletium and the probiotic blend) aren’t in any of the other three products. And if you already take magnesium or ashwagandha on its own, both are in here, at 200 mg and 250 mg.
One Jevi customer, S, put it in a line: “Saves on buying lots of different supplements.”
How you take it: two capsules once a day, preferably in the afternoon or early evening, with water. Each capsule is size 0, about 2 cm. The only other ingredient is the vegetable cellulose capsule.
What to expect: Jevi’s own page says it “isn’t a quick ‘calm hit’”. It’s taken every day, and the deeper benefits build with consistent daily use.† Everyone responds differently. Your first order has 60 days to decide.
Two capsules a day. About 2 cm each.

As listed on each brand’s own product page, 5 October 2026. Magnesium is shown as the figure each label prints for its magnesium compound. Not every label states elemental magnesium, so the figures are compared as printed. Prices left out because the brands sell in different currencies. Check each label before you buy.
If magnesium is all you want, BioRoot Labs lists more of it per serving. If you want healthy cortisol levels, calm, focus, mood, the gut-brain link and physical wind-down covered in one daily serving, Jevi is the only one in this table that lists an ingredient for each.
