Proof it works!
I feel the energy right away! Its a clean type energy: like I have drunk a good cup of coffee, yet without the jitters or "crash" 3-4 hours later! I took this one morning I needed to be up & going starting at 5 a.m. to 5p.m. and it kept me going and clear headed; super-focused! And, it don't interrupt my sleep. I have slept great thr following nights after taking this supplement. Definitely going to keep these on hand for those days i need an extra boost but its too late for an extra coffee.

Nitric oxide capsules
I have been taking nitric oxide capsules for approximately 3 months now. I’m 75 years old and in reasonably good health. I believe I have more energy and less tiredness since taking this supplement. I recommend this product, especially to anyone in my age group.

Energy to spare
I have been enjoying the energy boost I get with my new program on Berkeley Life. I am 69 and live in the mountains of Montana and hike many wilderness trails with my dog Tel.
-
So Impressed!
My doctor recommended these after my test strip was almost white ... just a faint tinge of pink. After taking two capsules daily, I can see the improvement (almost normal), and I can feel the results. Thank you!
-
I have more energy
I am on my third week of taking the Berkeley Life N.O. supplement. Within the past six months, I have had three surgical procedures requiring two hospitalizations. Being 74 years, I found myself left with fatigue and weakness. Since starting the N.O. I am now able to attend church, do my own cooking and cleaning. I plan to continue taking this!
-
More Energy
A friend told me about this and he said it was a game changer. Right away I started enjoying my busy days again.
-
I was a doubter!
Waited 6 months before submitting this review because I wanted to make sure of the long term outcomes first. Now, six months later I know Nitric Oxide really has improved my health. My energy level is up and my overall feeling of well being is better. Highly recommend this product to anyone of any age. I’m 70 years old and it has made an improvement in my daily feeling of well being.

Amazing pruduct
I have used these pills for approx 4 months. My strips initially showed a very pale pink. Now? It almost as dark as it can get. I am a heart patient. Cad and pad. Plus arteriosclerosis. I shall not stop purchasing this product for as long as I can afford it. Thank you so much Berkeley Dalia Tauber

Sample pack
I felt significant improvement in mood and energy levels after taking only 1 capsule daily for a week. Daily dose is two capsules. I have tried a lot of vitamins and various supplements, most without any noticeable change. This NO is different, it feels like it improves my heart health. For that reason, I am ordering more.

Berkeley life review
Hi, I waiteda little while to give this Berkeley life some time. And it is a terrific product. It does up my energy. I'm a 78 year-old woman with fibromyalgia and adrenaline and thyroid issues. I can definitely feel the difference with this product and encouraged that it is helping my blood vessels.
-
Great opportunity to try Berkeley Life!
I tried the sample pack, and the results were exactly as advertised. I tested before taking it and then 90 minutes later and saw a significant improvement. Can't go wrong trying Berkeley Life NO. Truly appreciate the opportunity to try the product before purchasing it for long term use.
-
Noticed a difference right away
I found that this really boosts my energy unlike anything else I have tried. I also know it is impacting my body based on the test strips.
-
Amazing results
I literally feel 20 years younger using "NO". I recommend it to everyone. Especially this product to all my friends and people I meet over 50. Thank you Berkeley for a healing product to give me my life back and in the best condition I couldnt 've done better on my own and I've tried. ❤️

Renewed Energy
I love the way I feel. Berkeley makes me feel my energetic! Someone said my skin looks bright. I thank God for Berkeley!

Energy in a capsule
I’ve had issues with my energy for many years, starting in my mid forties. After a lot of research and trial and error I’ve come across a few supplements that have made a real difference, and the Berkley Life product is one of them.
-
Excited so far!
I am intrigued by my results from the ten day trial. In the first few days I felt warmth in my fingers and toes that I haven't had in years. I also suffer from ME/CFS and chronic pain, by the end of the 10 day trial I felt energy starting to return that I thought I had no hope of ever feeling again and I realized I hadn't felt leg pain in maybe a week. I am a huge fan of this nitric oxide supplement and hope to be a life long customer.
-
Positive Improvement!
I am sooo excited about feeling stronger during the day. I have especially noticed that when working out I have felt less fatigue, easier breathing and more stamina. I am 67 years old and love to hike, bike, strength training and play Pickleball during the warmer months and cross country ski and kick box in the winter. Even though my husband and I have only been taking the dietary N.O. for a little over a month we have noticed feeling better. Thank you for making it available for us all.

Better now!
I’ve used Berkeley’s nitric oxide for about 3 years now. I have a long history of high blood pressure as well as fatigue and weakness. I did try another product about a year ago. My blood pressure increased and so did the fatigue. Needless to say, I’m back with Berkeley Life. All is well. In the summer, I cycle on average of 14 miles a day and I’m 70 years old.
-
Fascinating!
The test strips are so interesting and the supplement has improved My NO levels — and my energy! Will definitely be ordering more.
-
Better Energy
I have taken my nitric oxide for 8 days now. I have definitely noticed an increase in my energy!
-
No longer have afternoon fatigue
I have only been taking it for a week, but I notice I have more energy for my afternoon workouts and don't have as much fatigue at 3 pm at work. I will keep on taking this for the benefits.
-
Test rather than guess your NO levels
Profound system to not only but know supplement is impacting your health. Has been completely life-changing for my husband, and I will definitely spread the word to others. Amazing products.
-
4 Stars
I did notice that I felt good overall. I liked that I didn't have that jittery or nervousness feeling while using this supplement. But I felt amazing doing my every day tasks like work. Also loved that I didn't have a harsh crash.
-
Berkey Life
So far this has been the only product that moves my levels to appropriate ranges. Other products I have tried only moved me to the low range when tested.

I switched to Berkley Nitric Oxide and noticed a difference in my energy after a couple of weeks. The other product that I had used didn't really make a difference. This is an excellent product. Highly recommend!

Questions women ask before they start
Does this contain hormones?
No. There are no hormones of any kind in this formula. It works on a different pathway entirely, supporting your body's own Nitric Oxide production through dietary nitrate.
Can I take this alongside HRT?
Yes. It is compatible with hormone therapy. There are no hormones of any kind in this formula, so it is not doing the same job. Estrogen is one road to Nitric Oxide and dietary nitrate is the other, and this takes the second one. As with anything you add while you are on a prescription, it is worth telling your prescriber.
I already take several supplements. Does this replace them?
No, and it is not meant to. Keep taking what you take. This addresses one specific pathway that most routines do not cover.
How soon will I see something on the strip?
Most people see a color change on the same day, about 90 minutes after the first dose. That tells you the conversion is working in your body. Where your level settles over the following weeks is the more useful number.
What if my strip doesn't change color?
The most common reason is antiseptic mouthwash, which removes the tongue bacteria the conversion depends on. Switch to a non-antiseptic rinse for a few days and test again.
When should I take it?
Two capsules once a day with water, after food. Most people take them in the morning.
What if it doesn't work for me?
Every order is covered by a 30-day money-back guarantee. The strips mean you will know where you stand well inside that window.
