About Us

Greene Nutraceuticals™

Greene Nutraceuticals was created out of our founder Errol Greene's struggle with a severe case of brain fog. You can read his full story below or watch it here:














"Saved" (his words), by a variety of nootropic substances, he realized that others might be helped the same way he had been.


At the same time, he recognized that buying nine nootropics separately was not only expensive, but required a lot of pills which weren't a lot of fun to take.


From this challenge, our first product, Instant Clarity™ Nootropic Cocktail was born. 


Since then, we have expanded our supplement line to assist people seeking greater immunity during the Covid-19 pandemic (Immune Gummies), and will soon be releasing a Keto diet product that can assist with reducing weight and associated health challenges related to metabolic challenges. 


Our Founder's Story:

"It was while trying to board a flight from Atlanta to Los Angeles in 2017 that I knew I was in trouble."

My name is Errol Greene, and I'm the founder of Greene Nutraceuticals. I was only in my early 50's at the time, but I knew something was wrong—for the past year, my ability to think and remember had reached a critical point.


How would I continue my career? Or travel without someone to help? What was going on inside my brain, and… did I really want to know?

You may have experienced something similar in your own life. We all have good and bad days, but those of us in our 40’s and above can occasionally have scary bouts of brain fog. Days that make us question if it's just a bad day, or something more serious.

How it started

While traveling through airport security two years ago, I placed my laptop, tablet, and phone in the x-ray tray like everyone else in line. Lucky me, a TSA agent pulled my carry-on aside and asked to examine it.


“Sure, that’s fine,” I said. I knew nothing in the bag was problematic. I dutifully went back to the TSA table and let them scour my bag.  Nothing found, they thanked me for my cooperation, gave my bag back, and sent me on my way. 


It was only as I was about to board my flight... that I realized I had left my laptop at security.

Now, if you've ever experienced this yourself, you know how this feels. The realization of what you've done provides a severe shock to the brain, followed by a horrific sensation in the pit of your stomach. You see your work, personal, and financial life— and loss thereof— all flash before you.

My flight was scheduled to leave in twenty minutes, and I was approximately two miles from security (it's a big airport in Atlanta). Having no choice, I left my seat, explained the situation to the flight attendant, and proceeded to go back into one of the largest airports in the world and navigate my way back to security.


Without my computer I had no way to function once I got to LA. If I didn't have a computer, there was no reason to even go.

After running what seemed like miles, I eventually retrieved my laptop- after it had been sent to the airport lost and found – and as you've probably guessed, missed my flight.


Fortunately, a late flight that evening was still available, which I took. I arrived in LA past midnight and finally got to my hotel... at 2:20 am.

I laid in the hotel bed realizing something was very, very wrong my my cognition. But what, if anything, could I do about it?

The brain fog continues

But my brain fog was far from done with me. That year, I left my cell phone in my car at the airport, lost countless pairs of reading glasses, sunglasses, notebooks, umbrellas, and a few other items that, surprise, I didn’t even realize I had lost until I needed them.

I often forgot names of new business associates within a minute of the introduction. Organizing my thoughts for presentations was difficult. I couldn’t present effectively because I often couldn’t find the basic words I needed to make my points and stay focused.

Fearing the worst, I finally reached out to my doctor for testing. To say I was nervous was an understatement, but I gathered my courage, made the appointment and steeled myself for the news, whatever it was.

Diagnosis and treatment plan

I requested an Alzheimer’s test, but based on our recent interactions, my doctor said she didn’t think that was the problem. Instead, she asked about my diet, age- related issues, and lifestyle.

Based on that conversation, she decided that I should first try a variety of nootropic supplements. Nootropics are substances designed to improve cognitive function, memory, creativity, or motivation in otherwise healthy individuals. I'd never heard of them, but was open to trying anything if that meant I didn't have Alzheimer's and would think more clearly.

Recommended nootropic supplements


The first and most important supplement she suggested was vitamin B12. My diet is a more plant-based and she believed a B12 deficiency might be a contributing factor. Many people don’t realize the critical role B12 plays in the function and development of the brain, nerve cells, and the myelin sheaths that protect nerves and blood cells – or how common it is to be deficient in it. This vitamin is often used to treat memory loss, poor concentration, Alzheimer’s disease, and to boost energy levels and mood. In short, you can’t go wrong making sure you’re getting enough B12.


Secondly, she suggested taking Phosphatidylserine. After asking her to pronounce and spell it several times, she told me that it is a phospholipid that covers and protects brain cells. It enables and supports synapses, allowing them to interact and communicate effectively.


NIH studies report this supplement can help older people with memory issues as well as younger people with ADHD. It even helps the body recover from the stress of exercise. As a result, Phosphatidylserine plays an important role in keeping our minds and memories sharp. It’s believed that as we age, our levels of this important phospholipid decrease, so supplementing can lead to a marked increase in cognition, especially in those over 40.


The third supplement recommended was Huperzine A. She explained it is used by some doctors as an early-stage Alzheimer’s supplement, supporting memory and learning enhancement and fighting age-related memory impairment. It is known for increasing alertness and energy, and for protecting nerve damage. The key however, is not taking too much, so she prescribed a small daily dosage.


Ginkgo is a supplement well known for its antioxidant and anti-inflammatory properties. It is believed to increase blood flow and support better processing of neurotransmitters in the brain. This was one with which I was familiar with as I had taken it previously, but hadn't noticed much effects. She told me that by combining it with phosphatidylserine it would become more effective.

Vitamin C

Most people don't realize that the first recognized nootropic substance was... Vitamin C. Vitamin C plays a critical role in brain health by aiding in nerve impulse transmission, making it crucial to cognitive performance. Several enzyme reactions including catecholamine synthesis and collagen production are all enabled by having enough vitamin C. 

That may sound complicated but it essentially means your brain has the foundational building block chemicals it needs to function properly.


Her final suggestion was chromium picolinate. “Chromium? How does that help the brain?” I asked. She said many people aren’t aware they have low-blood sugar sensitivity and how that sensitivity can lead to bouts of brain fog. I agreed with her, remembering some of my worst issues occurred when I was especially hungry and hadn't had time to eat.

My results

Anxious to get started, I ordered all of the above and within just a few days I felt substantially better. The best way I can explain it is that if felt like a squeegee had cleaned the dirt off my brain's windshield; what had been murky was suddenly… clear.


Really clear.

I also had more energy. My mood had improved. People said I seemed more optimistic. Life was not only back to normal, it felt better. 

In some ways, I'm now able to think even more clearly than I had in my 20’s and 30’s when I dealt with ADD.


I now remember names easily. I no longer leave important pieces of my life at restaurants and airports. In fact, I’m the one who now catches others leaving their things behind. I’m able to communicate effectively again. I no longer search for my words.


In short, I’m me again.

The bottom line

I learned from my experience that while it’s difficult to have a high quality of life with brain fog, there is hope for cases even as bad as mine. I know now to periodically monitor my health benchmarks and make sure my brain has the essential nutrients it needs to function properly.


We can all play an active role in leading better, more productive lives if we proactively address our cognitive issues. And as we age, we will likely all experience them at one time or another.


But hopefully you'll do be able to do it without having to run through an airport to find a lost laptop.


Always consult your personal physician for specific medical advice.
