Introducing Frequency, the podcast by Phi. Episode 1 is live.
Dr. Warren G. Kramer III, MD has spent 35 years putting pro surfers, skaters, and motocross athletes back together. He is the surgeon Kelly Slater and Ryan Sheckler call after the worst slams. In our first episode, he takes apart what he has learned about how the body actually heals.
A few things from this one that will stick with you:
• Rest and ice can slow your recovery down. The doctor who coined “RICE” later apologized for it.
• PRP may give your body six months of healing in one shot by restarting a repair it forgot to begin.
• Your muscles protect your bones as much as calcium does. After 40 you lose 10 percent of your strength every decade, and that loss, not weak bone, is often what breaks you.
• D3 alone is not enough. You also need K2 to help direct calcium into your bones, which is exactly why we paired them in Stack™.
“You can’t build a strong house out of soft bricks.” His father’s line, and the whole episode in one sentence.

A new study looked at whether daily cocoa flavanols or multivitamins could help protect memory and focus in older adults. More than 2,000 people took either a cocoa extract, a multivitamin, both, or a placebo for three years.
The multivitamin improved cognitive performance, while cocoa did not. Before looking to exotic plant extracts, it's worth making sure the body has the essential nutrients it needs every day.

Each Stack capsule is filled with over 2,000 micropills that are 0.5mm in diameter.
Think of each micropill like a tiny snowball. They are rolled in purified plant fiber, and the thickness of the coating determines when they release in your body.
Each micropill is finished with a top coat which gets slippery when wet, making them very easy to swallow.
