5 reasons to try Stress Reset 

1. Break free from cortisol overload
Modern life keeps your cortisol stuck on “high,” leaving you wired, tired, and on edge. Stress Reset helps promote healthy cortisol rhythms with clinically studied adaptogens like Shoden® Ashwagandha and SalidroPure™, so you can feel calm, clear, and resilient—even on your most stressful days.*

2. Stay calm and emotionally steady (without feeling numb)

High cortisol doesn’t just drain your energy — it disrupts mood and emotional balance. Stress Reset supports healthy serotonin activity with ingredients like Zembrin® and Saffron, helping reduce emotional reactivity and ease occasional anxiety. The result? You stay relaxed and grounded without feeling foggy or sedated.*

3. Clear brain fog and regain mental clarity

Stress-induced cortisol spikes hijack cognitive function, making focus and decision-making harder. Stress Reset helps protect and optimize neurotransmitter balance, enhancing cognitive flexibility and clarity. Whether facing deadlines or decompressing after work, you’ll think sharper and feel more present.*

4. Support steady energy without stimulant crashes

Cortisol swings can leave you drained after stress hits. Stress Reset helps sustain natural energy with adaptogens and mitochondrial support from SalidroPure™ and Shoden® Ashwagandha—keeping you energized, focused, and resilient, without relying on harsh stimulants or suffering crashes later.*

5. Ingredient dosages that actually work

No underdosed ingredients or mystery fillers here. Each ingredient is used in its clinically studied dosages with proven results, increasing reliability and effectiveness. We also third-party lab test every ingredient in every batch - something most companies don’t do.

*These claims are based on a previous version of the Stress Reset formula, called Confidence. The data comes from an open-label consumer perception survey conducted in September 2024, which included a minimum of 37 customers who had been using that version for at least 60 days. Participants received a $10 rebate for sharing their feedback. The previous formula included Saffron, Ashwagandha, Magnesium, DHH-B, Zembrin®, and optionally caffeine and L-theanine. The formula has since been updated. A new study evaluating the current formula is planned, and updated claims are expected by August 2025.
