This score ranges from −5 to 5; the higher the score, the higher the probability of being a natural product. Natural products are more likely to be safe, with reduced risk of toxicity. NP score for 4-hydroxyisoleucine is 0.99, which is in this safe range.

WebBioavailability is less or equal to 100% for any other route of administration. The term absolute bioavailability is used when the fraction of absorbed drug is related to its i.v. bioavailability. The term relative bioavailability is used to compare two different extravascular routes of drug administration. The term bioequivalence is used when ... WebLow bioavailability of fluoride (2–32%) was reported in humans from diets commonly consumed in India [68]. The data presented show a wide range of bioavailability (2–79%) of fluoride from different foods in adults and that factors such as pH, the amount of ingested food, and the presence and type of minerals in ingested food are also important.
