The difference between naming an ingredient and disclosing exactly how much is in each serving.
A long ingredient list looks impressive. A short list with exact doses tells you more. Here's the difference.
A "named ingredient" tells you what's present. A "dosed ingredient" tells you exactly how much. HoneyFil's Supplement Facts panel states a specific milligram amount for all seven of its ingredients — Tongkat Ali at 200mg down to Grape Seed at 50mg.
Studies on an ingredient like Ashwagandha are typically conducted at specific dosages. Knowing the exact amount in a product lets you compare it against what's actually been studied.
A proprietary blend lists a combined total weight for several ingredients without breaking out individual amounts, which makes this kind of comparison impossible.
Look for a Supplement Facts panel with a per-ingredient dose, not just an ingredient list. If a product only lists names with no milligram amounts, that's worth asking about.
