WHAT IS BIOAVAILABILITY?

Bioavailability is the percentage of an active substance that actually reaches the bloodstream after administration, and therefore becomes available to act in the body .

In other words, it is the portion of an ingredient that the body can actually use after it has been absorbed, transformed, or eliminated by the digestive system, liver, or kidneys.

Concrete example:

- If a capsule contains 100 mg of biotin but the body only absorbs 40 mg , its bioavailability is 40% .

- An intravenous injection, on the other hand, has 100% bioavailability , because the active ingredient goes directly into the blood.

Comparative table of bioavailability

Shape Method of administration Absorption rate Average bioavailability Benefits Disadvantages
Gummies Oral (chewed) Slow to medium (15–45 min) ≈ 30–40% Pleasant taste, better adherence, easier digestion Less concentrated, presence of sugars or gelling agents, digestive losses
Capsule / tablet Oral (swallowed) Average (30–60 min) ≈ 40–60% Easy to dose, stable, economical Absorption varies depending on digestion; may irritate the stomach
Oral ampoule Oral liquid (partial sublingual absorption) Quick (5–20 min) ≈ 70–90% Very good absorption, no need for solid food digestion, fast action Sometimes has a strong taste; requires careful storage and opening precautions.
Intravenous (IV) Direct injection into the blood Immediate (0–5 min) ≈ 100% Total bioavailability, immediate effect Invasive, for medical use only, risk of side effects
