Normally, the amount of biotin in the body is regulated by dietary intake, biotin transporters (monocarboxylate transporter 1 and sodium-dependent multivitamin transporter), peptidyl hydrolase biotinidase (BTD), and the protein ligase holocarboxylase synthetase. When any of these regulatory factors are inhibited, biotin deficiency could occur. [23]
Biotin is stable at room temperature and is not destroyed by cooking. The dietary biotin intake in Western populations has been estimated to be in the range of 35 to 70 μg/day. Nursing infants ingest about 6 μg/day. [4] Biotin is available in dietary supplements, individually or as an ingredient in multivitamins. [1] [3]
Data from the Third Health and Nutrition Survey in the United States revealed that only 42.5% of adults over 71 years old met adequate zinc intake levels, with many suffering from zinc deficiency. To reach the upper tolerable limit of 40 mg per day, zinc intake from both food and supplements must be considered to help normalize serum zinc ...
Biotin is an essential B vitamin that helps the body convert food into energy and supports skin and hair health. Add these 7 biotin-rich foods to your diet for benefits.
However, having too much or too little zinc can compromise these functions. Zinc is a critical component of the catalytic site of hundreds of kinds of different metalloenzymes in each human being. In its structural role, zinc coordinates with certain protein domains, facilitating protein folding and producing structures such as 'zinc fingers'.
Experiments show that soil and foliar application of zinc fertilizer can effectively reduce the phytate zinc ratio in grain. People who eat bread prepared from zinc-enriched wheat show a significant increase in serum zinc, suggesting that the zinc fertilizer strategy is a promising approach to address zinc deficiencies in humans.
Eating more than 2 grams of protein per kilogram of bodyweight is likely too much, unless your lifestyle or a health condition requires it, says Gans. ... whether you're eating too much or too ...
