What Is NAT20?

NAT20 is a premium exogenous ketone supplement made by Prüvit, a leading ketone company. NAT20 provides your body with beta-hydroxybutyrate (BHB), the most bioavailable ketone body, in the form of ketone salts.

When you consume NAT20, your blood ketone levels rise within 30-60 minutes, providing immediate energy and triggering metabolic benefits similar to fasting or a ketogenic diet,without requiring dietary changes.

NAT20 comes in multiple flavors and is designed for daily use by anyone seeking rapid weight loss, enhanced mental clarity, improved athletic performance, or optimized metabolic health.

How NAT20 Works

NAT20 works through a multi-step metabolic process:

Step 1: Rapid Ketone Elevation When you consume NAT20, the BHB ketone salts dissolve in your digestive system and enter your bloodstream within 30-60 minutes. Your blood ketone levels rise to 1-3 mmol/L, creating a state similar to nutritional ketosis.

Step 2: Energy Production Your brain and muscles immediately use ketones for fuel, providing sustained energy without the crashes associated with glucose and carbohydrates.

Step 3: Metabolic Switch Even if you’re not fasting or following a ketogenic diet, NAT20 signals your body to activate fat-burning pathways, increase growth hormone, and suppress appetite.

Step 4: Cellular Benefits NAT20 triggers autophagy (cellular cleanup), reduces inflammation, improves mitochondrial function, and supports longevity.
