Balance of Nature is a major advertiser on Kevin McCullough Radio, where Howard has a weekly segment. McCullough is a conservative commentator who frequently appears on Fox News. Kevin McCullough Radio airs on WMCA (AM 570) and WNYM (AM 970) in New York City (he also hosts a video version of his show called Radio Night Live).

McCullough has previously promoted Balance of Nature as a potential treatment for cancer and other medical problems. He stated in June 2017: “If you’re struggling with some health areas, and Dr. Howard, I don’t think there’s any limit on what these things can really help, at least not in the overwhelming amount of response that you’ve had. I mean, if you’ve got -- if you’re struggling with cancer, if you’ve got hep-C, if you’ve got other types of deficiencies, get this stuff going. What can it hurt if it gives you that relief or begins to help you in that way that is really powerful?”

In May 2017, he promoted a segment with Howard and wrote: “Literally did more to cure my flu this year than any anti-viral or antibiotic Ive ever used.” In September 2017, McCullough wrote: “Whether you struggle with skin irritations, diabetes, Hep C, cancers, lower abdominal, prostate issues, low energy, and literally tons of other areas, the power of whole fruit and vegetables and their tens of thousands phytonutrients to improve every cell in your body has been peer-reviewed, and medically observed. ... They radically changed my life. I used to get sick every time the weather changed, but now taking fruits and veggies I haven't had even one bronchial, asthmatic, allergy, cold or flu.”

McCullough and Howard are now turning their sights to the coronavirus and pitching Balance of Nature as a solution.

During McCullough’s February 27 show, he and Howard discussed ways to protect against the coronavirus. After talking about aspects related to health, Howard concluded by telling listeners that “the key is, for example, I do take Balance of Nature. That’s what I take.” McCullough then went for the sale, stating: “To reiterate, and I want to be very clear, doc’s not saying fruits and veggies will cure anything. He’s not saying that it'll cure you from anything. What he’s saying is it will help your immune system be the fighters that your body needs when it is attacked and this is the kind of best defense that we’ve got against corona and those other, even the flu, and other things right now.” McCullough added that people should “order more than just the basic dosage so that you can boost that immune system and be ready in the event that you come into contact with something that you shouldn’t be.”

On March 5, Howard dismissed the hypothetical coronavirus vaccine, stating: “I’ll be honest, I’m not going to run out and do this vaccination anyways because I’ve been working on this for weeks and months and years of my own immune system and it’s not too late for everybody to start, and we briefed on this last time a little bit, but I’d like to hit a little bit more on what can you do to take away some of this hysteria.”

Later while discussing ways to fight the coronavirus, Howard said: “If you feel a symptom, then you have to hit it extra hard. And so I’m talking to all of our, all of our -- the people who have listened to me in the past that are taking Balance of Nature, for example, and living by this health triad, which is what I call this. If you’re living by the health triad and you start to feel a symptom, then you hit it back hard. Double up. Triple up. There’s nothing, you know, with Balance of Nature -- there’s no toxicity.” McCullough followed up by asking, "You can’t overdose on it, is what he’s saying?” to which Howard replied: “No.”

During a March 19 segment about the coronavirus featuring Balance of Nature, McCullough concluded by stating that he’s “upped my dosage the last couple of weeks because I am the one person in the house that’s been going out and having contact with the public, even at the grocery stores and stuff. So, I’ve got to tell you, it’s working for me. I think it will work for you.”
