My Oura Ring actually picked this up.

I track my sleep religiously. Usually, my Deep Sleep is around 45 mins. After 4 days on the Rezo Night protocol (Magnesium stack), I’m consistently hitting 1h 20m. I didn't think a supplement would show up in the data that fast, but the numbers don't lie. The morning focus is subtle—not a caffeine hit, just... clear."

Good packaging.

Bought this for my husband because he complains about brain fog. He likes the packaging and the fact that it's a simple AM/PM system. Will update after 30 days of use.

Finally, a stack that isn't 10 different bottles.

My counter used to look like a pharmacy. I love that Rezo just simplified it to 'Day' and 'Night.' The Lion's Mane in the morning helps me lock in for coding sessions. Taking one star off because the shipping box was slightly dented, but the bottles were fine. Will subscribe if the feeling lasts.

Weird... I didn't crave my 2pm latte.

I’m usually a 3-cup-a-day person. I bought this to try and cut down on the jitters. Day 1 was rough (caffeine withdrawal), but by Day 3, I realized I had worked straight from 9 AM to 1 PM without looking up or walking to the coffee machine. The 'Flow State' claim is actually real. It’s a very calm energy, not buzzy.

Impressive delivery speed.

I ordered this because I've been reading about the benefits of Lion's Mane. It arrived in 2 days. The packaging looks very premium. Starting the protocol tomorrow morning.

Finally a bundle that makes sense.

I used to buy Magnesium and Mushroom supplements separately and it cost me over $100. This bundle is way cheaper and easier to remember. Love the concept.
