Hear from those enjoying calmer days & nights

Here's the truth...

Your body is running on stress mode - all day long

Do you...

  • Wake up already tense, heart racing?
  • Crash at 2pm and crave sugar?
  • Feel "tired but wired" - and can't switch off?
  • Lie awake at 2am replaying the day?
  • Snap at the people you love?

Stress impacts your body a lot more than you think. When cortisol stays high, it doesn't just ruin your evenings - it quietly runs your entire day.

3 steps to naturally calm down with Nello Supercalm

Step 1

Step 1

Fill your cup with 8-16 oz of water or your favorite beverage.

Step 2

Step 2

Mix in 1 stick of Nello's Supercalm

Step 3

Step 3

Stir, sip, and chill! Feel the calm wash over you. Enjoy!

Supercalm isn't another supplement to forget. It's a daily ritual that tells your body it's safe to power down - clinically-dosed actives in a zero-sugar mocktail you actually crave.

The goodness inside each drink

KSM-66® Ashwagandha

300mg

The most-studied ashwagandha extract for stress. It helps regulate cortisol - your primary stress hormone - so your nervous system can finally stand down.

Cortisol

In a 60-day randomized, double-blind, placebo-controlled trial of chronically stressed adults, 300 mg KSM-66 lowered serum cortisol by 27.9% vs 7.9% on placebo - with significant drops in stress and anxiety scores.

Chandrasekhar K, et al. Indian J Psychol Med. 2012;34(3):255–262.

L-Theanine

400mg

The calm-focus amino acid from green tea. It takes the edge off without making you drowsy - present, not sedated.

Anxiety

In a 4-week randomized, placebo-controlled trial, 200 mg/day of L-theanine reduced stress-related and trait-anxiety scores and improved sleep quality (PSQI).

Hidese S, et al. Nutrients. 2019;11(10):2362.

Magnesium Glycinate

100mg

Supports muscle relaxation and sleep. The glycinate form is far better absorbed than cheap magnesium oxide - with none of the stomach upset.

Absorption & sleep

In a randomized, placebo-controlled trial, magnesium bisglycinate improved insomnia-severity scores vs placebo — and reviews show glycinate absorbs more completely than oxide.

Randomized placebo-controlled trial, Nat Sci Sleep. 2025. Bioavailability: Nutrients reviews.

Vitamin D3

1,000 IU

The "sunshine" vitamin for mood. Most people run low - especially indoors - and low D is linked to a lower emotional baseline.

Mood

A dose-response meta-analysis of 31 randomized trials (24,189 people) found each 1,000 IU/day of vitamin D reduced depressive symptoms, with moderate certainty.

Meta-analysis, Psychological Medicine. 2024.

What to expect*:

This is the one everything else rests on. Ashwagandha helps bring cortisol back toward baseline, and L-Theanine shifts your brain toward alpha waves, the state you're in when you're relaxed but wide awake. The result is less wound up, not less awake.

Supercalm isn't a sleep aid and it isn't a sedative. It works earlier in the chain, on the stress load that leaves you lying there with a busy head at midnight. Bring that down and falling asleep stops being something you have to try at.

Chronic stress flattens everything. In trials of chronically stressed adults, ashwagandha lowered self-reported stress and anxiety scores alongside cortisol. Less noise running in the background tends to show up as more patience, more evenness, and more room for the good parts of your day.

The 2pm sugar hit isn't weak willpower, it's cortisol. Sustained stress pushes your body to reach for fast energy, which is why stress and sugar cravings travel together. Ease the cortisol and the pull eases with it. Zero sugar, so it never feeds the cycle.

L-Theanine is why this doesn't feel like winding down toward a nap. It's associated with relaxed alertness, the calm-but-switched-on state, which is exactly why people pair it with coffee. Steady attention, without the jitter running underneath it.

Cortisol tells your body to hold on to sodium and water, and that's where a good deal of morning puffiness comes from. Magnesium supports normal muscle function and recovery. Bring the stress load down and your body stops holding on quite so hard.

Stress impacts your body a lot more than you think. When cortisol stays high, it doesn't just ruin your evenings - it quietly runs your entire day.
