What Is Ashwagandha?

Definition:

Ashwagandha (Withania somnifera) is an adaptogenic herb that has been used in Ayurvedic medicine for thousands of years. Adaptogens help your body adapt to stress by modulating the stress response system.

How It Works:

Ashwagandha works by:
- Modulating the HPA (hypothalamic-pituitary-adrenal) axis
- Reducing elevated cortisol levels
- Supporting stress response balance
- Helping your body maintain homeostasis under stress

The Science:

Research shows "A New Ashwagandha Formulation (Zenroot™) Alleviates Stress and Anxiety Symptoms While Improving M..." (Adv Ther, 2025) [PMID: 40875185] that ashwagandha supplementation significantly may reduce cortisol levels in high-stress individuals. Studies "Ashwagandha as an Adaptogenic Herb: A Comprehensive Review of Immunological and Neurological Effe..." (Cureus, 2025) [PMID: 41356880] have also found that ashwagandha reduces stress and anxiety, which directly supports sleep since stress is a major contributor to sleep problems.

Best For:

  • People with elevated daytime stress
  • Those who experience evening cortisol spikes
  • Individuals whose sleep problems stem from stress activation
  • People who need long-term stress support

Timing:

Take ashwagandha in the afternoon (around 2-3 PM) to support your stress response system throughout the day and prevent evening cortisol spikes that disrupt sleep.

What Is Magnesium Glycinate?

Definition:

Magnesium glycinate is a highly bioavailable form of magnesium bound to glycine, an amino acid that supports relaxation. Magnesium is an essential mineral involved in over 300 biochemical reactions in your body, including those related to sleep.

How It Works:

Magnesium glycinate works by:
- Supporting GABA (gamma-aminobutyric acid) production
- Promoting nervous system calm
- Supporting muscle relaxation
- Helping may regulate melatonin production

The Science:

Studies have "Association Between Dietary Magnesium Intake and Sleep Quality in Saudi University Students: A Cr..." (Nat Sci Sleep, 2025) [PMID: 41426202] found that magnesium supplementation may improve sleep quality, sleep time, and sleep efficiency, particularly for people with insomnia or stress-related sleep problems.

Best For:

  • People who struggle with sleep onset
  • Those who experience mental activation at bedtime
  • Individuals who need nervous system support
  • People whose sleep problems stem from mental overactivity

Timing:

Take magnesium glycinate 30-60 minutes before bed to support your nervous system's transition into rest mode and promote sleep onset.

Can You Take Both Together?

Yes—They're Complementary, Not Competing

Ashwagandha and magnesium glycinate work together beautifully because they address different aspects of sleep challenges:

  • Ashwagandha addresses daytime stress that causes evening sleep problems
  • Magnesium Glycinate addresses evening mental activation that prevents sleep onset

How They Work Together:

  1. Afternoon (2-3 PM): Take ashwagandha to support stress response throughout the day
  2. Evening (30-60 min before bed): Take magnesium glycinate to support sleep onset

The Science:

Research shows that addressing both stress activation (ashwagandha) and nervous system calm (magnesium glycinate) provides more comprehensive sleep support than either supplement alone.

The Mind Calm Starter Set:

The Starter Set combines both supplements for comprehensive support:
- Ashwagandha ($39) - Afternoon stress support
- Magnesium Glycinate ($52) - Evening sleep support
- Total Value: $91 → Set Price: $79 (13% savings)

Frequently Asked Questions

Yes, ashwagandha is generally safe for daily use when taken at recommended doses (typically 300-600 mg of extract). However, it's important to consult with a healthcare provider before starting any supplement, especially if you have thyroid conditions, are pregnant or breastfeeding, or take medications. Most studies show safe daily use for up to 8-12 weeks, with some people using it longer under medical supervision.
Most people notice improvements in sleep quality and stress reduction within 2-4 weeks of consistent ashwagandha use. However, some may experience benefits sooner, while others may need 6-8 weeks. The effects are cumulative, so consistency is important. Taking ashwagandha in the evening can help with sleep, while morning doses may be better for daytime stress management.
For sleep support, the best time to take ashwagandha is typically 1-2 hours before bedtime. This allows the supplement to help reduce cortisol levels and promote relaxation as you prepare for sleep. Some people also benefit from splitting the dose—taking a smaller amount in the morning for stress management and a larger dose in the evening for sleep support.
Ashwagandha can often be safely combined with other sleep supplements like magnesium or melatonin, but it's important to consult with a healthcare provider first. Ashwagandha works primarily on stress and cortisol regulation, while magnesium supports muscle relaxation and melatonin regulates sleep timing. Combining them can provide complementary benefits, but professional guidance ensures safety and optimal dosing.
