What the Label Data Shows

L-5-MTHF 25,500 mcg DFE is a compact, 4-ingredient vitamin supplement from Seeking Health, sold in capsule form, cataloged in the NIH Dietary Supplement Label Database (DSLD). These ingredients span 3 nutrient categories, other, vitamin, amino acid, reflecting a multi-component formula rather than a single-nutrient product.

With only 4 ingredients on the label, 4 of 4 fall outside the FDA's reference-intake system -- a tight formula built mostly from botanicals, amino acids, or specialty compounds without a set Daily Value benchmark, which is routine for a focused label like this one.

Market status matters for supplement research. This product is currently listed as on-market in the DSLD, with its label first entered into the database on 2024-11-22. An on-market listing means the product is currently sold in the United States; the DSLD catalogs the label as submitted but does not independently verify the claims or evaluate safety or efficacy.
