Understanding Exogenous Ketones: What They Really Are
Before diving into products, it’s essential to understand what exogenous ketones are. In simple terms, ketones are molecules your body produces when it burns fat for fuel instead of carbs. When you eat fewer carbs, your body enters a state called ketosis.
Exogenous ketones are simply ketones you consume from an outside source (like supplements), instead of relying solely on your body to make them. They usually come in two forms:
- Ketone salts: Ketones bound with minerals like sodium, calcium, or magnesium.
- Ketone esters: A purer, more potent (and expensive) form of ketones, usually used in clinical or athletic settings.
These supplements are designed to help your body transition into ketosis faster, fuel workouts, and reduce brain fog.
Why People Take Exogenous Ketones
Different people use exogenous ketones for different reasons. Some want fat loss, others chase mental performance, while athletes often need them for endurance. Here’s why they’re popular:
- Faster entry into ketosis
- Reduced keto flu symptoms
- Boosted energy and endurance
- Enhanced mental clarity and focus
- Appetite suppression for weight loss
Think of them as a jumpstart button for your keto journey.
How to Choose the Best Exogenous Ketones Supplement
Not all ketone supplements are created equal. If you want real results, pay attention to these factors:
- Type: Are you buying salts or esters? Most supplements for regular use are salts.
- Taste: Many ketone supplements taste bitter, so flavor matters.
- Price per serving: Some brands are costly without offering real benefits.
- Additives: Check if the product is clean or loaded with fillers and sugar.
- Reputation: Go with trusted brands that back their claims.
