Is 5-methyltetrahydrofolate an alternative to folic acid for the prevention of neural tube defects?
Obeid R, Holzgreve W, Pietrzik K. Obeid R, et al. J Perinat Med. 2013 Sep 1;41(5):469-83. doi: 10.1515/jpm-2012-0256. J Perinat Med. 2013. PMID: 23482308 Free article. Review.
Unmetabolized FA appears in the circulation at doses of >200 mug. Individuals show wide variations in their ability to reduce FA. ...In contrast to FA, 5-methylTHF has no tolerable upper intake level and does not mask vitamin B12 deficiency. Supplementatio …

Micronutrient profiles in HIV-1-infected heterosexual adults.
Skurnick JH, Bogden JD, Baker H, Kemp FW, Sheffet A, Quattrone G, Louria DB. Skurnick JH, et al. J Acquir Immune Defic Syndr Hum Retrovirol. 1996 May 1;12(1):75-83. doi: 10.1097/00042560-199605010-00011. J Acquir Immune Defic Syndr Hum Retrovirol. 1996. PMID: 8624765
There is compelling evidence that micronutrients can profoundly affect immunity. We surveyed vitamin supplement use and circulating concentrations of 22 nutrients and glutathione in 64 HIV-1 seropositive men and women and 33 seronegative controls participatin …

An unusual case of autoimmune agranulocytosis with total absence of myeloid precursors: demonstration of diverse sources of R binder for cobalamin in plasma and secretions.
Carmel R. Carmel R. Am J Clin Pathol. 1983 May;79(5):611-5. doi: 10.1093/ajcp/79.5.611. Am J Clin Pathol. 1983. PMID: 6837526
During agranulocytosis, levels of the R binder for cobalamin in the blood were greatly diminished (20-60 pg/mL unsaturated binding capacity). ...This confirms that granulocytes are responsible for most of the circulating R binder in humans. In contrast, salivary R b …
