Piperine, a bioactive compound found in many dietary supplements, plays a key role in the absorption of other compounds.
Piperine is a bioactive compound from black pepper (Piper nigrum L.) that gives pepper its characteristic pungent taste. In recent decades, it has become one of the most interesting ingredients in dietary supplements, mainly because of its effect on the bioavailability of nutrients. [1]
Bioavailability means how much of an ingested substance your body actually absorbs and uses. Research shows that piperine specifically influences absorption processes in the digestive system, improving how well certain bioactive compounds are utilized. [2]
That’s why black pepper extract is often used in dietary supplement formulas, like Junai HER and Junai HIM, where it complements the effects of other ingredients.
What is piperine
Piperine is a natural alkaloid found in the fruits of the plant Piper nigrum (black pepper). It’s the very compound that gives black pepper its characteristic spicy taste and is one of the main bioactive components of this spice. [3]
In modern dietary supplements, you usually won’t find piperine used as the spice itself, but as a standardized black pepper extract, where the content of the active compound is precisely defined. This kind of standardization allows for a more tightly controlled formulation and consistent product quality.
Why standardization to 95% piperine matters
Most often, an extract standardized to ≥95% piperine is used, which means that the vast majority of the extract is the active molecule piperine. This lets you use very small amounts of the extract while maintaining the stability and effectiveness of the formulation.
In the Junai HER dietary supplement, an extract of black pepper fruits (Piper nigrum L.) is used, in which piperine is the main active component. The extract has a standardized high piperine content (>95%) and is obtained through a controlled extraction process in which the plant’s active compounds are concentrated and stabilized.
According to the Junai HER ingredient specification, the extract contains:
extract of the fruits of Piper nigrum L.
plant-to-extract ratio approximately 50–60:1
standardization to ≥95% piperine
carrier maltodextrin
This form of extract lets you precisely dose a very small amount of the ingredient (in Junai HER about 2 mg of extract per daily serving), which acts as a supportive element of the formulation and complements the effects of the other plant-based ingredients.
Piperine and nutrient absorption
Research shows that piperine can affect various absorption mechanisms in the digestive tract.
Possible mechanisms include:
effects on enzymes involved in nutrient metabolism
effects on the transport of molecules across the intestinal wall
effects on metabolic processes in the liver [4]
Because of these properties, piperine is often used in dietary supplement formulas when you're looking to improve the bioavailability of certain ingredients.
Bioavailability means how much of an ingested substance your body actually absorbs and can use. Some plant compounds or vitamins can break down in the digestive system or get absorbed only in a very small fraction.
Research shows that piperine can influence certain processes in the digestive tract that are involved in the passage of nutrients through the intestinal wall. Because of this, it’s often used in formulations as a supportive ingredient that complements the action of other bioactive compounds. [1] [2]
In complex formulas like Junai HER and Junai HIM, black pepper extract therefore plays mainly a synergistic role, helps optimize the formulation, and complements the effects of other ingredients.
Simply put: piperine helps your body better use certain nutrients and plant compounds that you take with a dietary supplement.

Why use a standardized black pepper extract
In herbal dietary supplements, it’s not just about which plant you use, but also how its extract is prepared. That’s why you’ll often see a standardized extract used in modern formulations, where the amount of the key bioactive compound is precisely defined.
Standardization means the manufacturer ensures a consistent, verified content of the active substance in every batch of the product. That matters because the natural content of bioactive compounds in plants can vary depending on growing, processing, and extraction conditions.
In black pepper extract, the key active compound is piperine. In dietary supplements, extracts standardized to ≥95% piperine are therefore most commonly used.
This form of extract has several advantages:
it lets you have a precisely defined amount of the active compound in every dose
it ensures formulation stability and predictability
it enables consistent product quality across different batches
Because of the high concentration of the active compound, the standardized extract is used in very small amounts, where it acts as a supportive ingredient in the formulation.
That’s why you’ll often find a black pepper extract with a high piperine content in complex dietary supplement formulas, where it complements the effects of other bioactive ingredients.
