The PureLung 600 mg Proprietary Blend and the Ceiling Math

Quick answer

The label lists eleven names inside one 600 mg blend, in descending order of weight. That order sets a ceiling for each: the nth name weighs at most 600 divided by n, so the first can be up to 600 mg and the fifth at most 120 mg. Ceilings are limits, not amounts, and the real doses are unknown.

What is a proprietary blend?

A proprietary blend is a mix whose total weight is printed but whose parts are not. Companies use the format to keep a recipe private. Rules require the names to be listed in order from most to least by weight (FDA, FDA 101: Dietary Supplements).

That order is a clue, and you can turn it into a ceiling using arithmetic any reader can check.

How the ceiling works

Each name must weigh no more than the name before it. Suppose the nth name weighs x. Every earlier name weighs at least x, so n times x is at most 600 mg, which means x is at most 600 divided by n.

What the ceilings do not tell you

They are upper limits. The real weights could be far lower. A name in 3rd place might weigh 20 mg, and the rest sit with the first two. The math cannot find the real split, and it never shows that an ingredient is present at a helpful dose.

Why this still helps

Use ceilings as a sanity check. A page that claims a precise amount of an ingredient in this blend has invented it.

The weight of the first names

Himalayan pink salt is first, so it is the heaviest. It could be up to 600 mg of the serving. Cinnamon extract is second, and so on. The label does not say how large the leaders are. If the salt were heavy, the capsule would carry more sodium than one would guess from a "natural" label.

What to ask a seller

  • Can you provide the per-ingredient amounts for my lot?
  • Which extract ratios and plant parts are used?
  • Is there a certificate of analysis that confirms the amounts?

A seller that provides them is making the blend more open. A seller that refuses has told you something.

What does the PureLung label say?

The label shows 60 capsules, a serving of 2 and a 600 mg Proprietary Blend of eleven names with no single amount; it names no disease.

Why this matters for safety

Ginkgo is eighth and green tea extract is eleventh, so each is at most 75 mg and about 55 mg per serving respectively. That is a ceiling, not a dose, and it is reassuring only in the sense that the figures cannot be larger. The proprietary blend page shows the full workings, and the facts page shows the panel.

FAQ01

PureLung questions people ask

Is 600 mg the dose of each name?

No. It is the total for all eleven in a serving.

Can I trust the order?

The rules require descending order, so it is reliable as a ceiling.

Are the bottom names tiny?

They may be, but the label does not say.

Why do companies use blends?

To keep recipes private.

Can I get the real amounts?

Ask the retailer. Do not accept guesses.
