Recommended Daily Allowance

For children, pregnant people, adults older than 75 years and adults with high-risk prediabetes, the guideline recommends vitamin D higher than the IOM recommended daily allowance.

The recommended daily allowance of 0.36 grams of protein per pound of body weight per day is not enough, as that’s the amount needed to avoid a protein deficiency.

Today in Nature Plants, a team led by Cathie Martin, a plant metabolic engineer at the John Innes Centre, reported that knocking out a single gene created tomatoes which could each provide 20% of the recommended daily allowance of vitamin D in the United Kingdom.

Q. What is 18 hours short of the recommended daily allowance?

Kids in the treatment arm were given daily vitamin D supplements of 4000 international units, or seven times their recommended daily allowance, and some reached serum levels above 100 ng/ml.
