Absorption and Bioavailability of CBD Oil
The manner in which CBD is absorbed into the body plays a crucial role in its efficacy. The bioavailability, or the percentage of CBD that ultimately enters the bloodstream, varies significantly depending on the method of consumption. Understanding absorption and bioavailability is essential to fully exploit CBD oil's potential.
Sublingual Absorption
In sublingual absorption, CBD oil drops are placed under the tongue and held there for a few seconds to several minutes before swallowing. This method allows the CBD drops' active ingredient to be quickly absorbed through the mouth's mucous membranes directly into the bloodstream. The biggest advantage of this method is bypassing the digestive system and liver, leading to higher bioavailability and a faster onset of CBD effects.
Digestive Tract and Bioavailability
Conversely, swallowing the CBD oil dosage means it has to pass through the digestive tract and is metabolized in the liver before entering the bloodstream. This process, known as the "first-pass effect," can reduce the amount of CBD ultimately utilized, thus decreasing bioavailability. However, swallowing offers a prolonged release of CBD in the body, leading to a longer duration of effect.
Bioavailability and Efficiency
The bioavailability of sublingually absorbed CBD is generally higher than that of swallowed CBD. Studies suggest that sublingual methods can achieve bioavailability rates of up to 35%, while oral consumption often presents significantly lower rates. This means a lower dose of CBD is needed to achieve similar effects when the CBD products are held under the tongue.
