Metabolic health dictates your daily energy, brain clarity, and long-term health span. Today, poor metabolic fitness drives chronic fatigue, weight gain, and modern diseases. Many people look for shortcut supplements to fix their bodies. However, two ancient physical stressors offer a powerful alternative: deliberate heat and deliberate cold exposure. Read more about metabolic health. Combining saunas and cold plunges creates a unique physical challenge. This practice is often called contrast therapy. It does more than burn calories or test mental grit. It changes your cellular physiology, stabilizes blood sugar, and upgrades mitochondrial function. This comprehensive guide breaks down how thermal shock alters your metabolism. You will learn how saunas and cold water impact glucose spikes, insulin sensitivity, and metabolic rate. Part...

How FDA PreCheck Strengthens U.S. Drug Supply Chain

FDA Commissioner, Marty Makary


The U.S. Food and Drug Administration has begun accepting requests to participate in the FDA PreCheck pilot program

FDA PreCheck is designed to strengthen the domestic pharmaceutical supply chain by increasing regulatory predictability, facilitating the construction of manufacturing sites in the U.S., and streamlining aspects of pharmaceutical manufacturing facility assessments in advance of a specific product application.

"After 35 years of globalists taking pharmaceutical manufacturing overseas, the FDA is taking bold steps to bring it back," said FDA Commissioner Marty Makary, M.D., M.P.H.

 "The PreCheck program is one of several powerful incentives we are providing to make the U.S. pharmaceutical manufacturing sector more resilient and competitive."

According to the agency, it will select an initial cohort of new pharmaceutical manufacturing facilities and begin conducting PreCheck activities in 2026. 

Facilities will be selected based on overall alignment with national priorities across multiple selection criteria, such as products to be manufactured, phase of facility development, timeline to producing pharmaceutical products for the U.S. market, and innovation in facility development. Additional priority consideration will be given to facilities producing critical medications for the U.S. market, FDA said.

The FDA incorporated extensive industry feedback into the program design based on comments made during the "Onshoring Manufacturing of Drugs and Biological Products" public meeting held on Sept. 30, 2025, and public comments received through Federal Register publication.

The Agency said the PreCheck consists of two phases. In Phase 1, the Facility Readiness Phase, selected manufacturers will engage with FDA for early technical advice before a facility is operational through pre-operational reviews and utilization of a facility-specific Drug Master File to facilitate efficient evaluation of facility-specific elements prior to, and in support of, the submission of a drug application, it said.

In Phase 2, the Application Submission Phase, FDA and applicants build upon Phase 1 and engage through pre-submission meetings and inspections to resolve issues and expedite assessments of manufacturing information in a drug application, the Agency said.
