More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give limits on both standard and optimal (or target) ranges.
One way to differentiate between folate deficiency and vitamin B 12 deficiency is by testing for methylmalonic acid (MMA) levels.

Folic acid, which is the synthetic form of the vitamin folate, is critical both in pre- and peri-conception. [7] Deficiencies in folic acid may cause neural tube defects (NTDs). Women who had 0.4 mg of folic acid in their systems due to supplementing 3 months before childbirth significantly reduced the risk of NTDs. [29]
