Bilberry Leaf in PureLung: Leaf, Not Berry
The label says bilberry leaf powder, not the berry. It is listed sixth in the PureLung blend, so it can weigh at most 100 mg per serving, and the real amount is not printed. Most bilberry research uses berry extract for the eye, and leaf has been studied far less, with a caution for people on diabetes medicine.

Which part of the plant is it?
Bilberry is a European relative of the blueberry. The fruit is dark and rich in pigments called anthocyanins, and most supplement research uses fruit extract. The PureLung label names leaf powder, which is a different part of the plant with a different profile.
Many pages blur the two. When you read about bilberry benefits, check whether the study used berries or leaves.
Where does it sit in the blend?
Sixth of eleven. The ceiling is 600 divided by 6, so 100 mg per serving. The actual amount may be much lower. For comparison, the studies of berry extract often used amounts of 80 to 480 mg of a standardised extract, and such products state their strength, which this label does not.
What research covers
Berry extract has been studied for eye strain and circulation with mixed results, and leaf has been studied mainly in small trials and animal work, with a focus on blood sugar (MSK, Bilberry Fruit). None of it asked about breathing or the lungs.
A page that cites bilberry berry studies to support a leaf powder ingredient has swapped one thing for another.
Safety notes
Bilberry leaf may lower blood sugar. If you take diabetes medicine, a change in dose may be needed, so tell your pharmacist. Large amounts of leaf over a long time have been linked to harm in older reports, which is why most references suggest short, moderate use.
- People on insulin or tablets for diabetes should ask first.
- People about to have surgery should say they take it, since blood sugar control matters.
- People who are pregnant or nursing should avoid it unless a clinician agrees.
- Stop if you notice shakiness, sweating or confusion, which can be low blood sugar.
