Urolithin A is not known to be found in any food but rather forms as the result of transformation of ellagic acids and ellagitannins by the gut microflora in humans. [ citation needed ] Sources of ellagitannins are: pomegranates, nuts, some berries (raspberries, strawberries, blackberries, cloudberries), tea, muscadine grapes, many tropical ...
In studies using supplemental urolithin A, dosing varied from 250 mg to 1,000 mg. Prest points out that some adverse events were observed at higher doses, “so if you take supplemental urolithin ...
Chemical structure of urolithin A.. Urolithins are microflora metabolites of dietary ellagic acid derivatives, such as ellagitannins. [1] They are produced in the gut, and found in the urine in the form of urolithin B glucuronide after absorption of ellagitannins-containing foods, such as pomegranate. [2]
Toxicity results from ingesting too much preformed vitamin A from foods (such as liver), supplements, or prescription medications and can be prevented by ingesting no more than the recommended daily amount. Diagnosis can be difficult, as serum retinol is not sensitive to toxic levels of vitamin A, but there are effective tests available.
Megavitamin-B 6 syndrome, also known as hypervitaminosis B 6, vitamin B 6 toxicity, and vitamin B 6 excess, [a] is a medical condition characterized by adverse effects resulting from excessive intake of vitamin B 6.
Toxic units (TU) are used in the field of toxicology to quantify the interactions of toxicants in binary mixtures of chemicals. [1] A toxic unit for a given compound is based on the concentration at which there is a 50% effect (ex. EC50) for a certain biological endpoint. One toxic unit is equal to the EC50 for a given endpoint for a specific ...
Addition of research on rats is not encyclopedic to implicate anti-disease properties per WP:PRIMARY.Early-stage human rsearch is ok, but all the animal studies and different disease models can be condensed to a single sentence, e.g., "Laboratory research on the potential roles of urolithin A includes models of lifespan, inflammation, muscle function, and cancer."<refs> The content on ...
Vitamin D toxicity, or hypervitaminosis D, is the toxic state of an excess of vitamin D. The normal range for blood concentration of 25-hydroxyvitamin D in adults is ...
