Humann FAQs
2026 Packaging Redesign
Why does Humann packaging look different?
Did the product change?

When will the new look be everywhere?
The new design begins rolling out in January and transitions across shelves through April, depending on location.
Why change the look now?

Science & Clinical Studies
What foods can I eat to increase my Nitric Oxide production?
Many foods, such as spinach, nuts, artichokes, beetroot, and certain green teas, are rich in dietary nitrates, which convert in the body to Nitric Oxide. However, one of the known facts about Nitric Oxide is that it gets harder to consume enough of these nitrate-rich foods in order to compensate for the declining Nitric Oxide production levels of your body as you age.
When should I ask my doctor about Nitric Oxide?
As with any nutritional supplement, check with your physician, pharmacist, or qualified healthcare professional when changing up your daily regimen. Note that many practitioners are just now learning about the incredible benefits of Nitric Oxide, and aren’t necessarily aware of products like Neo40. To provide the best information for both consumers and medical professionals, our website includes a plethora of facts, methodology, research and clinical studies. If your healthcare provider isn’t familiar with the latest studies about N-O, simply direct them to Humann.com.

What is NoFraud and why did I get an email from them?
Humann has partnered with NoFraud, a fraud prevention solution for eCommerce businesses. NoFraud screens transactions on our behalf and alerts us if they find a transaction is at high risk for fraud. This protects our customers against unauthorized credit card use.
You may have received an email, call or text from NoFraud because your transaction with us had irregular shopping characteristics and/or elevated risk. NoFraud just wants to confirm the purchase was made by the authorized cardholder. If an order cannot be verified, it is automatically refunded and cancelled within 48 hours of being placed.
