What the Label Data Shows

With 29 ingredients on the label, Essential 1 with 1000 IU Vitamin D3 is one of the more extensive other combinations supplement formulas from ProCaps in the NIH Dietary Supplement Label Database (DSLD), sold in capsule form. These ingredients span 5 nutrient categories, vitamin, mineral, non-nutrient/non-botanical, fiber, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 29-ingredient formula, 29 of 29 sit outside the FDA's reference-intake system entirely -- common at this scale, since multi-ingredient blends tend to accumulate botanicals, amino acids, and specialty compounds the FDA has never benchmarked. That's expected breadth, not a red flag on its own.

A product's market status is worth checking before relying on this label. This product is currently listed as on-market in the DSLD, with its label first entered into the database on 2025-06-25. This product is actively distributed in the U.S. right now. As with every DSLD entry, that listing reflects the manufacturer's self-declared label, not an independent safety or efficacy review.
