How Bioavailability Affects Your Body and Results

Bioavailability is a term often used in health and nutrition contexts, but what does it actually mean, and why is it so important?

What is Bioavailability?

Bioavailability describes how much of a nutrient or substance is actually absorbed and used by the body. It’s a critical factor in determining how effectively a vitamin, mineral, or medication works. If a nutrient has low bioavailability, a significant portion doesn’t reach the bloodstream, reducing its benefits to the body.

Example: When taking a magnesium supplement, bioavailability can vary depending on the form used, such as magnesium citrate (high availability) versus magnesium oxide (lower availability).

Factors That Affect Bioavailability

Several factors influence bioavailability:

1. Form of the Nutrient: Some forms are easier for the body to absorb. Liposomal vitamins and minerals often have higher bioavailability than traditional tablets.
2. Individual Factors: Your age, health, metabolism, and digestive efficiency determine how effectively your body can absorb nutrients.
3. Food and Drink: Certain nutrients absorb better with fats (e.g., vitamin D), while others may be hindered by antinutrients found in some foods (e.g., iron and calcium).
4. Delivery Method: Liquid forms, powders, and capsules can vary in availability. Sublingual (under the tongue) or transdermal (on the skin) products bypass the digestive system, often offering higher absorption.

How to maximize your diet

To get the most out of your food and supplements, consider the following:

• Combine the Right Nutrients: Some vitamins and minerals work synergistically, such as vitamin C and iron.
• Avoid Absorption Blockers: Limit coffee and tea with meals, as they can reduce iron absorption.
• Choose the Right Supplement Form: Look for supplements with high bioavailability, such as liposomal or chelated minerals.
• Eat a Balanced Diet: Whole foods naturally contain combinations of nutrients that enhance absorption.

Why is bioavailability important for biohackers?

For biohackers focused on optimizing health and performance, bioavailability is a cornerstone concept. It’s not just about consuming nutrients but ensuring the body can use them in the best possible way. By understanding and optimizing bioavailability, you can achieve better results with fewer supplements.

Bioavailability is key to understanding how your body absorbs and uses nutrients. By selecting the right forms of nutrients and optimizing their absorption, you can improve your health and maximize the effectiveness of your diet and supplements.
