Whether it's thinking more clearly, improving mood, strengthening immunity, losing weight, or having more energy, Greene Nutraceuticals™ offers ultra-high quality supplements that we give to our own families. 

All of our supplements are manufactured in the USA, in cGMP, FDA-approved labs to the highest standards of quality. We will never manufacture or sell a supplement or health product that doesn't meet our rigorous standards. 

But here's what truly separates us from other supplement companies:

You can try our products below our cost.

And, if you like them, you'll get them at a monthly discount.


If you don't, you can cancel your subscription after the second month

and pay nothing else.


In fact, if we accidentally bill you after you cancel,

you can keep the product as our gift to you!


We hope you find this approach to purchasing supplements new and reassuring. It's the way we would want a company to do business with us, too.

I'm Errol Greene, the Founder of Greene Nutraceuticals™ and this is my pledge to you:

I couldn't find the supplements I needed so I started my own company to produce them. I personally take and use every single item you see on this website.


Every product we manufacture and promote is something we take ourselves and give to our families.


They've all passed rigorous testing, are manufactured in the USA a cGMP certified facilities, and all have Certificate of Analysis guaranteeing what you are buying is what you actually get.

I believe you should be able to try whatever you are buying and see if it's right for you. Many supplements work well for some people and not others.


I've tried supplements that some people raved about felt nothing. You need to know if they are right for you, so we will always offer heavy discounts on initial purchases and refund options if the products  are, for any reason, not for you.

I also know that not all supplements are for all people. If you watch my videos, I always explain who are supplements are designed to help, and who they are not for. Who will benefit, and who might not. It's the right way to do things.

If you cancel a subscription with us, that means you've canceled it. If we make a mistake and bill you again, that's not your fault, it's ours and we'll eat it. As long as you cancel following your second month delivery, you will not be charged again. And if we send it to you by accident, you can keep the product.

I believe in treating you like you would want to be treated. Maybe you love everything we make, maybe you don't, but as a customer of Greene Nutraceuticals™, you'll always be treated like we value your business, because we do.

I hope you'll give us a try and let us show you our commitment to offering the highest quality products.


If you have any questions, please reach out to and we'll be glad to help any way we can.

Keeps me sharp all day!

Reviewed in the United States on March 3, 2020

Verified Purchase

I've been reading about nootropics and stumbled upon this product and I figured it was worth a try. I am more than impressed! I usually have a 3-4 pm crash but with this product, I have sustained energy and alertness all day. I'm a chiropractor and I am on my feet all day, physically active and mentally stimulated all day long. Instant Clarity keeps me sharp all day. I definitely recommend this product.

Clarity & energy- no crash feeling

Reviewed in the United States on June 26, 2020

Verified Purchase

It definitely works!!! Gives me clarity and energy without the jitters! I drink it instead of my afternoon coffee! Also it doesn’t give you the crash feeling like other products! I would love it in a berry or grape flavor!!

It works

Reviewed in the United States on December 16, 2019

Verified Purchase

It does give me clarity! I like it better than coffee in the morning. No jitters. I personally don’t like the taste. Strong artificial sweetness and some citrusy notes. If you don’t mind diet drinks you may like it.
Arrived quickly, nicely packaged.

Instant Clarity is a must for a clear brain!

Reviewed in the United States on November 18, 2019

Verified Purchase

A friend of mine gave me a jar of Instant Clarity to try and boy was I surprised how quickly my foggy brain cleared. I was a little skeptical at first but am definitely a believer. I have already purchased my 2nd jar and will continue using it going forward. It is truly a must try!

Real energy without a sugar crash

Reviewed in the United States on August 12, 2019

Verified Purchase

What I like most about Instant Clarity is that it keeps me steady and energized throughout the day, all day. It really, seriously works on the energy front, with no caffeine jitters.

The chromium and B12 I would take any way so I’m happy to skip taking those supplements separately. It does make me more alert (and slightly smarter). I feel a real difference when I don’t drink it. Coffee just doesn’t stack up!

One note, some natural sweeteners can sometimes upset my stomach, but no problems at all with Instant Clarity.

Overall, 100% recommend.

My “go to” for lifting the brain fog!

Verified Purchase

Instant Clarity has really made a difference in my daily life. It lifts the brain fog and helps me focus much more clearly on my task at hand . My whole sense of well being has changed for the better. I gave it a try for a month so that I could give an accurate review. Now it’s part of my daily routine!

Instant Clarity Delivers on Its Promise for Boosted Energy, Mood and Focus!!!

Reviewed in the United States on August 19, 2019

Verified Purchase

I have been looking for an energy drink that would give me a boost for daily work outs without the jitters of coffee and tea – When I read about Instant Clarity I was enamored with the promise of more energy, mood and focus. After trying it for the first time I can honestly say that this product delivers on its promise – I had so much energy I had to force myself to get off the treadmill after a solid hour of jogging! I love the taste and that it is a sweet, refreshing drink, yet sugar free without using artificial sweeteners. If you want more energy, give Instant Clarity a shot – It’s the real deal and perfect in the morning or late afternoon as a natural pick me up!

An Amazing Surprise

Reviewed in the United States on July 12, 2020

Verified Purchase

I have long been skeptical of the whole "nutraceuticals" trend, having been suckered by outrageous claims, but I have to say Instant Clarity was an amazing surprise. Like many of us who are staying at home due to Covid-19, I've been busying myself with home improvement projects. I've been taking Instant Clarity for 3 days now, and I've gotten more done in those 3 days than I did in the previous 2 weeks ! The increase in my energy level is remarkable, and there is no crash at the end of the day. Thank you for making a product that actually delivers on it's promises. I am happy to rate this 5-Stars.
