Vitamin B6 in PureLung: Seventh of 11, and the Limits That Matter
Vitamin B6 (as pyridoxine) is the seventh name in the PureLung blend, so it can weigh at most 85.7 mg per serving of 2 capsules, with no amount printed and no percent Daily Value. The NIH sets an upper level of 100 mg a day from food and supplements, and very high long-term intakes can injure nerves. No lung benefit was found in the NIH fact sheet.

What it is01
What is vitamin B6?
Vitamin B6 is a water-soluble vitamin that helps the body handle protein and make brain chemicals and red blood cells. It is found in fish, poultry, potatoes, chickpeas and fortified cereals. The label lists it "as Pyridoxine", the common supplement form.
The NIH Office of Dietary Supplements gives the tolerable upper intake level for adults as 100 mg a day from food and supplements together (NIH ODS, Vitamin B6). The page does not say B6 supplements help lung health. The only respiratory mention it makes is that people who take the drug theophylline often have low B6, which is a point about a medicine, not about a benefit.
On the label02
What does the PureLung label show for it?
It is the seventh of eleven names in the blend, with no amount printed and no percent Daily Value, though B6 is a nutrient that has one in most labels. The weight order means it weighs at most 600 divided by 7, about 85.7 mg (FDA, Q&A on Dietary Supplements).
| Name on the label | Vitamin B6 (as Pyridoxine) |
|---|---|
| What it is | vitamin |
| Place in the list | 7 of 11 in the Proprietary Blend (heaviest name first) |
| Amount | inside the 600 mg blend; no separate amount printed |
| Most it could weigh | 85.7 mg per serving of 2 capsules |
| Usually sold for | Needed in small amounts for normal metabolism |
| Lung benefit in a trial of this capsule | None. No study of PureLung found |
| Main caution | Very high long-term intakes can injure nerves; the NIH upper level is 100 mg a day from food and supplements together. |
That ceiling is below 100 mg, so one serving of PureLung could not exceed the upper level on its own. But the true amount is unknown, and many people take B6 in multivitamins and B-complex products, so the total across products can add up.
Lung evidence03
Is there evidence for B6 and the lungs?
No. The NIH fact sheet covers many topics and does not give a lung benefit for B6 supplements (NIH ODS, Vitamin B6). We found no trial of B6 for asthma, COPD or lung function in the sources we read.
B6 is a nutrient the body needs in small amounts. A person with a low level may need more, which a blood test and a clinician can find. Taking extra when you are not low has not been shown to help the lungs. That is a common pattern with vitamins in lung products.
Safety04
What are the cautions?
Very high long-term intakes injure nerves. The NIH says chronic intakes of 1 to 6 g a day have caused severe, progressive sensory neuropathy (NIH ODS, Vitamin B6). That is many times the upper level, and a capsule blend is far below it. The point is that "more" is not always better, and that B6 sits in several products people take at once.
Symptoms of nerve trouble include numbness, tingling and unsteady walking. If you notice them, stop all B6 products and call a clinician. If you take theophylline, ask a pharmacist about B6.

Adding up05
How do you add up B6 from several products?
Read each label for B6 and write it down: multivitamins, B-complex, energy drinks, protein bars and fortified cereals often hold it. Add them with what you get from food, which is small. If the total is near 100 mg, talk to a pharmacist.
PureLung does not print a B6 amount, so you cannot add it. That is one more reason to ask the order desk for the figure if you take other B6 products. A ceiling of 85.7 mg is a worst case, not a likely one, but you cannot rule it out from the label.

What should you ask?
Ask the order desk how many milligrams of B6 are in a serving. Ask a pharmacist to add up your products. If you have numbness or tingling, tell a clinician. And remember the label lists B12 too, covered on the vitamin B12 page.
Forms07
Is B6 the same as the form on other labels?
Pyridoxine is the most common form in supplements. Another form, pyridoxal 5'-phosphate, is sold as the active form. The label here says pyridoxine, so we use that. The forms differ in how the body handles them, and the upper level applies to B6 from all forms. If you use another product with a different form, add them together.
Role08
What does B6 do in the body, in plain words?
It helps enzymes that break down and build amino acids, supports the making of brain chemicals and helps form hemoglobin, the part of red blood cells that carries oxygen. That last role is why B6 sometimes gets named in breathing-related ads, since oxygen is carried by blood. A vitamin that helps make the carrier is not a vitamin that changes how the lungs work, and the NIH page makes no such claim (NIH ODS, Vitamin B6). A person with a low level feels tired, and a doctor can test for it. That is the proper path, not a guess from a capsule label.
Overlap09
What if you take a multivitamin as well?
Most multivitamins hold B6 at around the daily need, and B-complex or "stress" formulas hold more. Add PureLung to that and the unknown part grows. Keep a list of every product with its B6 amount, and ask your pharmacist to add the totals. If the sum is high, drop one product, and favor the one with a printed amount and a clear purpose. A blend with no B6 figure is the easiest one to drop.
