What is meant by fiber-mineral interaction and mineral-mineral interaction?
Fiber-mineral interaction refers to the ways in which dietary fibers can influence the absorption, bioavailability, and functionality of minerals in the digestive system. This interaction can affect how well minerals like calcium, iron, and zinc are absorbed, as certain fibers may bind to these minerals and reduce their availability. On the other hand, mineral-mineral interaction involves the competition or synergy between different minerals in the body, where the presence of one mineral can enhance or inhibit the absorption of another. Both types of interactions are crucial for understanding nutrient absorption and overall mineral balance in nutrition.
What is the bioavailability of a drug?
Bioavailability of a drug refers to the fraction of the administered dose that reaches systemic circulation in an unchanged form. It is a measure of the extent and rate at which the active ingredient is absorbed and becomes available at the site of action in the body. Bioavailability is influenced by factors such as route of administration, drug formulation, and first-pass metabolism.
Can a drug which is 100 percent absorbed from GI tract have 100 percent bioavailability?
No, a drug that is 100 percent absorbed from the gastrointestinal (GI) tract would not necessarily have 100 percent bioavailability. Bioavailability is affected by factors such as first-pass metabolism in the liver, which can reduce the amount of the drug that reaches the systemic circulation unchanged. Thus, even if a drug is fully absorbed, its bioavailability may be less than 100 percent.
What is the rate and extent to which a vitamin is absorbed and used in the body is known as?
intrinsic factor
What in your bodies can bind with minerals and limit their absorption?
Compounds like phytates, oxalates, and tannins found in food can bind with minerals like iron, calcium, and zinc in the digestive tract, reducing their absorption in the body. Consuming foods high in these compounds alongside mineral-rich foods may decrease the overall bioavailability of those minerals.
What is bioavailability?
Bioavailability is the amount of drug which reaches the site of physiological activity after administration.
How does first-pass effect affect bioavailability of drugs?
relationship between the first pass effect and bioavailability
What is the percent of bioavailability of a folate supplement taken on an empty stomach?
Bioavailability refers to the amount of a vitamin that is absorbed and used by the body. When a folate supplement is taken on an empty stomach, the bioavailability is 100 percent.

What shows the highest bioavailability for calcium?
CASCAVAL
Why is opium given rectally?
More bioavailability.
What is a bioequivalence?
A bioequivalent is a formulation of a drug which is equivalent to some other formulation in terms of bioavailability.
What is the bioavailability of a drug?
Bioavailability of a drug refers to the fraction of the administered dose that reaches systemic circulation in an unchanged form. It is a measure of the extent and rate at which the active ingredient is absorbed and becomes available at the site of action in the body. Bioavailability is influenced by factors such as route of administration, drug formulation, and first-pass metabolism.
Can you have a list of different drugs bioavailability?
cardiovascular drugs
What food shows the highest bioavailability for calcium?
CASCAVAL

What is bioavailability of ethanol?
Ethanol is a form of alcohol. Bioavailability is the extent and rate of a subtance's entry into the body's circulation system, so bioavailability of ethanol refers to the extent and rate of ethanol's entry into the body's circulation system. Ethanol in the gastric contents slows the peristaltic action that moves food through the stomach and delays stomach emptying.
