Simple Ways to Boost Nitric Oxide (Including Humming!)
Nitric oxide (NO) is a powerful molecule that supports blood vessel health, circulation, and heart function—but it’s not just influenced by diet. Certain daily habits can naturally increase NO levels, helping blood vessels function optimally and reducing the risk of heart disease.

Here are science-backed ways to increase nitric oxide naturally:
1. Eat NO-Rich Foods
Some foods naturally stimulate nitric oxide production, promoting better circulation and heart health. Beets, kale, garlic, and citrus are among the best choices.
  • Beets provide dietary nitrates, which the body converts into NO. They also contain betalains, antioxidants that help fight inflammation and support brain function.
  • Kale is an NO superfood—it’s rich in vitamin C, which plays a vital role in efficiently converting nitrates into NO. This makes kale one of the best leafy greens for supporting vascular health.
  • Citrus and bell peppers provide extra vitamin C, which helps convert nitrates into nitric oxide. They also block harmful nitrosamines that can form when nitrates interact with certain proteins.
2. Exercise Regularly
Physical activity is a natural way to boost nitric oxide and enhance circulation.
 ✅ Aerobic exercise improves NO production and keeps blood vessels flexible.
 ✅ Resistance training supports NO levels, reducing inflammation linked to heart disease.
 ✅ Even short daily walks make a difference in stimulating NO release.

3. Humming—Yes, Humming!
Surprisingly, humming can increase nitric oxide production in the sinuses, helping with oxygen delivery and circulation.
Studies show that humming for a few minutes boosts NO levels, which can help:
 ✔ Clear airways 
 ✔ Improve oxygen exchange
 ✔ Support vascular health
A simple habit with surprising benefits!

4. Prioritize Sleep
Restorative sleep is essential for maintaining optimal NO levels. Poor sleep disrupts vascular repair processes and increases inflammation, which can lower nitric oxide availability.
  • Deep, consistent sleep helps stabilize NO production and protects cardiovascular health.
  • Sleep deprivation reduces NO levels, making blood vessels more prone to stiffness and inflammation.
By combining nutritious foods, regular movement, and simple daily habits, you can naturally restore nitric oxide levels, supporting long-term heart health and circulation. 

Next time you're out for a power walk, try humming your favorite songs—it’s an easy way to boost nitric oxide and support your health while you move!

This blog is dedicated to Irl Flanagan, who was my friend and grammar mentor. Over the last 20 or so years, he spent countless hours editing my manuscripts and teaching me the intricacies of sentence structure and the true meaning and the proper usage of words. 

Irl passed 4 months before his 100th birthday. He held my writing to a high standard, and I honor him by doing the same.

About Me

Most people want to feel better, live lighter, and get their numbers moving in the right direction — weight, blood sugar, blood pressure, cholesterol, energy. But lasting change doesn’t come from willpower or restriction. It comes from small, doable habits practiced day after day.

Peggy Kraus, MA, RCEP, CDCES, is a clinical exercise physiologist and diabetes care specialist who has spent nearly three decades helping people improve their health through simple, evidence‑based lifestyle changes. Her programs are grounded in research and built around habits that lower inflammation, support heart health, balance blood sugar, and make weight loss sustainable.

Peggy has worked with thousands of people, guiding them toward meaningful improvements in their health — from weight loss and lower glucose to better blood pressure, cholesterol, and energy. Her approach is practical, encouraging, and rooted in the belief that anyone can change their health by changing their daily habits.
