Breathizen lists five ingredients and a total blend weight of 154 mg, but does not disclose how those milligrams are divided. This is known as a “proprietary blend” and it is one of the most debated practices in the supplement industry.
Under FDA labeling rules, supplement makers can list ingredients in descending order by weight without disclosing the exact amount of each one. The total blend weight must be stated (154 mg in Breathizen’s case), but the split is proprietary.
The stated reason is competitive protection: they do not want competitors to copy the exact formula. Critics argue it also allows brands to use minimal amounts of expensive ingredients while listing them prominently on the label.
At 154 mg total across five ingredients, simple division gives an average of roughly 31 mg per ingredient. Studied doses for ginger start at 250 mg, for bromelain at 500–1,000 mg, and for cordyceps at gram-level. Even if one ingredient dominates the blend, the 154 mg ceiling means no single ingredient can carry a full studied dose.
We do not think this makes Breathizen worthless — many people report positive experiences with supplements at sub-clinical doses. But we do think this is the single most important piece of information to understand before ordering, and that full dose transparency would strengthen the product’s credibility significantly.
