Stress from work, family, or just the daily grind can wear you down. I’ve been there, juggling deadlines and personal responsibilities, and finding the right supplement has been a quiet game-changer for keeping my calm without feeling sluggish. After digging through Amazon.ca reviews and trying a few myself, I’ve narrowed it down to three top-rated stress relief supplements that actually work. These picks are backed by thousands of user reviews and solid clinical research, with no fluff—just real results.
1. PlantVital High Potency L-Theanine 250mg Capsules
Stress Level: General daily stress or mild anxiety
Why I Love It: This Canadian-made supplement delivers a high dose of L-theanine, an amino acid from green tea that promotes relaxation without knocking you out. It’s perfect for daytime use when you need to stay sharp.
- Pros: Fast-acting, non-drowsy, vegan, non-GMO
- Cons: May take a few days for full effects
I started using PlantVital L-Theanine about six months ago, mainly for those evenings when work stress keeps my mind racing. One capsule does the trick, helping me unwind without feeling groggy. It’s become a staple for better sleep and less tension, and my focus stays intact. With over 5,000 reviews on Amazon.ca and roughly 2,000 units sold monthly (based on sales rankings), it’s a crowd favorite.
What Users Say:
- “I take it before bed, and it stops my racing thoughts. Finally sleeping better.”
- “Great for work stress—calmer during meetings but still alert. No side effects after months.”
- “As someone with mild anxiety, this is a game-changer. Absorbs fast, less edge daily.”
Product Details: PlantVital offers 250mg of L-theanine per capsule in a 120-count bottle. It’s designed for temporary calm, aiding focus and sleep without sedation. A 2019 study in Nutrients found L-theanine reduces stress symptoms and boosts cognitive function by promoting alpha brain waves. A 2021 study in the Journal of the International Society of Sports Nutrition confirmed it helps buffer acute stress.
Key Ingredient:
- L-Theanine: Crosses the blood-brain barrier to boost GABA and serotonin, easing tension while supporting mental clarity.

- Pros: High-potency formula, vegan, supports energy and stress resilience
- Cons: May cause mild stomach upset if taken without food
I picked up Webber Naturals Ashwagandha 7200 mg last winter when stress from work left me tense and drained. Two capsules daily with meals, and within a week, my shoulders felt looser, and the constant worry eased up. It’s not instant, but it evens out energy over time.

A 2021 Phytotherapy Research review showed ashwagandha reduces stress and anxiety by 20-30% over 8 weeks. A 2024 Verywell Health analysis highlights KSM-66’s efficacy in improving stress response and energy levels.
