Bioavailability: Why It Matters How Your Body Absorbs Active Ingredients
What bioavailability means, which factors influence it and why hydroalcoholic extracts make the difference.

Series: Hydroalcoholic Extracts
This page is part of our series on natural extracts. Learn how they work, how they are produced and how they can support your daily wellbeing.
What Is Bioavailability?
Bioavailability refers to how well and how quickly a substance is absorbed and utilised by the body. Simply put: it's not just about what you take, but how much your body can actually use. High bioavailability means the active ingredients reach your cells efficiently – without loss.
Why Does It Matter?
Effective Absorption
Without good absorption, even the best supplement cannot deliver results. Bioavailability determines how much of the active ingredients actually reaches the body.
No Waste
With high bioavailability, your body makes the most of what you take. Less is lost, more arrives where it's needed.
Noticeable Results
A supplement with high bioavailability can make the difference between “I don't feel anything” and a tangible benefit in your daily life.
Hydroalcoholic Extracts: Superior Bioavailability
Hydroalcoholic extracts (tinctures) are among the forms with the highest bioavailability. Here's why:
Dual Solvent
Water and alcohol together extract a broader range of active compounds than a single solvent alone.
Rapid Absorption
The alcohol facilitates the dissolution of active ingredients, making absorption by the body faster and more effective.
Natural Preservation
The alcohol also serves as a natural preservative, ensuring stability and long shelf life without artificial additives.
Factors That Influence Bioavailability
Age and Metabolism
Metabolism changes with age. A faster metabolism promotes quicker absorption of active ingredients.
Health Status
Overall health and digestive system function affect how much the body can absorb and utilise.
Timing of Intake
Whether you take extracts on an empty stomach or with a meal can influence the speed and effectiveness of absorption.
Supplement Form
Liquid forms (such as tinctures) generally have higher bioavailability than tablets or capsules.
In Summary
Hydroalcoholic extracts offer high bioavailability thanks to their composition and specific production process. This makes them an effective choice for anyone seeking natural support for their wellbeing. The combination of water and alcohol ensures complete extraction of active compounds and optimal absorption by the body.

What does bioavailability mean?
Bioavailability indicates the percentage of an active ingredient that is actually absorbed and utilised by the body. The higher the bioavailability, the more effective the supplement.
Why do tinctures have higher bioavailability?
Tinctures (hydroalcoholic extracts) are already in liquid form and are absorbed more quickly than tablets or capsules, which must first be dissolved in the stomach.
When is the best time to take extracts?
Generally, taking extracts on an empty stomach promotes faster absorption. However, for those with sensitive stomachs, taking them with a light meal can be more comfortable.
