Two labels can list the same plant and very different milligram amounts without giving enough information to rank the products. Before comparing herbal supplements, record the material being described and avoid treating unlike numbers as equivalents.
What does the milligram amount describe?
Read whether the entry identifies plant material, a named extract or a declared raw-material equivalent. If the label does not say, ask the manufacturer. Do not silently change a plain plant entry into an extract or assume a concentration because another brand uses one.
Keep an extract ratio separate
A ratio such as 10:1 is a different piece of information from the ingredient weight. Ask what the manufacturer means by the ratio and which material the declared milligrams refer to. A raw-material-equivalent number is not automatically the actual weight of extract inside a capsule and does not by itself identify the amount of a particular compound.
Understand a standardized percentage
Suppose a hypothetical specification states that 100 mg of an extract contains 20% of a named constituent by mass. The arithmetic gives 20 mg of that constituent. This calculation is valid only for the stated specification; it does not prove that an unrelated product contains the same amount. The example is not the Fat Killer Plus formula.
What is known about Fat Killer Plus?
The composition image supplied for these guides lists ingredient names and quantities per four capsules. It does not provide extract ratios or standardization percentages for green coffee, garcinia, African mango, green tea or mate. We therefore do not calculate chlorogenic acids, HCA, EGCG or total caffeine from those entries.
Build a comparison that keeps unknowns visible
Use columns for ingredient identity, material type, amount, serving basis, declared ratio and standardized constituent. Write “not supplied” where appropriate. A higher milligram number is not a complete basis for a stronger-product or better-result claim.
