A Guide for Women on Mounjaro, Perimenopause, and Cognitive Wellness

If you’re using injectable medications like Mounjaro (tirzepatide) for weight loss or type 2 diabetes, you’re likely focused on improving your overall well-being, including mental clarity, energy, and mood.

But what about natural brain-boosting supplements like Lion’s Mane mushroom or creatine?

Are they effective? Safe to use alongside weight loss injections? And which is the better option, especially for women in perimenopause or menopause, navigating fatigue, hormonal shifts, and brain fog?


🍄 What Are Mushroom Supplements?

Mushroom nootropics like Lion’s Mane (Hericium erinaceus), Reishi, and Cordyceps are herbal supplements derived from medicinal fungi. Among them, Lion’s Mane has emerged as a frontrunner for brain support.

🌟 Benefits of Lion’s Mane:

  • Boosts nerve growth factor (NGF), aiding brain repair and memory
  • May improve mild cognitive impairment and support focus
  • Reduces anxiety and mood changes, especially in midlife women

🧪 Evidence:

  • 🧠 A clinical trial by Mori et al. (2009) found significant cognitive improvements in older adults with mild memory issues who took Lion’s Mane for 16 weeks.
