Question 3

Why do ingredient forms matter in Spring Valley Hair Skin & Nails?

Accepted Answer

The form of each ingredient determines how much active compound your body absorbs. Two supplements can list the same ingredient at the same dose, but the form used — such as Glycinate vs Oxide for a mineral — can result in very different amounts reaching systemic circulation. FormulaForge's formulary rates each form by bioavailability tier so you can compare products on ingredient quality, not just dose amounts. These statements are based on structure/function research and have not been evaluated by the FDA. This information is not intended to diagnose, treat, cure, or prevent any disease.

Rather than choosing from pre-made products, you select each ingredient and form individually, with dose ranges drawn from our research-backed formulary. These statements are based on structure/function research and have not been evaluated by the FDA. This information is not intended to diagnose, treat, cure, or prevent any disease.
