Why Generic "Brain Supplements" Fail
(And What To Do Instead)

Most people buy Lion's Mane, take it for 2 weeks, feel nothing, and quit.

Here's what they don't know: Neurogenesis (new brain cell growth) takes 4-8 weeks to produce noticeable results. Plus, if you have high cortisol from stress or poor sleep architecture, Lion's Mane alone won't work—you need a complete stack.

That's why we created this assessment. Instead of guessing which supplements to try, you'll get a protocol designed around:

  • Your primary cognitive challenge (brain fog, fatigue, focus, or burnout)
  • Your sleep quality (the #1 factor in cognitive function)
  • Your stress levels (cortisol blocks neurogenesis)
  • Your energy patterns (identifies root cause deficiencies)

The result? A supplement stack that actually works—because it addresses YOUR specific root causes, not generic symptoms.

"I've tried Lion's Mane before and quit after a week because I felt nothing. This quiz showed me I needed Ashwagandha and Magnesium too because of my stress and sleep issues. Now I'm 6 weeks in and my brain fog is GONE."

— Sarah M., Marketing Executive

"The 'Peak Performer' protocol with the B12 add-on was exactly what I needed. My afternoon crashes disappeared within 2 weeks. Worth every penny."

— James K., Founder

"Finally, someone explained WHY my supplements weren't working. The coaching emails kept me consistent through the 'nothing's happening' phase. Week 7 now and I feel sharper than I have in years."

— Rachel T., Software Engineer

Frequently Asked Questions

How long does the quiz take?

Just 60-90 seconds. We only ask the questions that actually matter for determining your protocol.

Is this quiz really free?

Yes, completely free. No credit card required. You'll only pay if you decide to purchase your personalized protocol afterward.

How is this different from just buying Lion's Mane on Amazon?

Three ways: (1) You'll know which complementary supplements you need (Ashwagandha, Cordyceps, Magnesium, B12) based on your specific root causes. (2) You'll get a realistic timeline so you don't quit too early. (3) You'll receive AI coaching to optimize lifestyle factors that affect results.

What if the supplements don't work for me?

We offer a 30-day money-back guarantee. If you don't notice improvement in mental clarity or focus, we'll refund you completely.
