Article Synopsis
- The study assessed serum folate concentrations in the fasting US population from 2011-2016 to evaluate the effects of folic acid fortification, focusing on various folate forms and their associations with demographic and lifestyle factors.
- Significant findings showed that age, sex, and race/ethnicity influenced folate levels, with differences observed in non-Hispanic whites, blacks, and Asians regarding specific folate types like 5-methyl-THF and unmetabolized folic acid (UMFA).
- The results indicated that older adults had a higher prevalence of UMFA, particularly those with chronic kidney disease, while factors like alcohol consumption and smoking were linked to lower folate concentrations.*
Article Synopsis
- Serum folate forms, particularly tetrahydrofolate, are prone to oxidation, but their stability can improve with the addition of ascorbic acid (AA).
- In a study analyzing serum with and without AA over various storage times at -70°C, results showed consistent recovery of folate forms, with most experiencing less than 10% loss over four years.
- The presence of AA was critical for achieving nearly complete recovery of tetrahydrofolate during sampling, indicating that AA helps maintain the stability of serum folate compounds over time.
