If you are highly sensitive to casein, we wouldn’t recommend trying this product.

We always recommend talking to your prescribing physician before using any supplements to ensure that they are safe to take with your medical history.

Can I take Redwood on an empty stomach?

Yes, all of our products can be taken by both men and women. Many women use Redwood for supporting blood flow and circulation.

Can I take Redwood and Vitamin C?

Redwood has 1000mg of Vitamin C per serving. Taking too much Vitamin C can draw water into the stool. If you are already supplementing with Vitamin C, lower your serving to 1-2 capsules twice daily instead of the normal 3 capsules twice a day.

I love this product - Umzu Redwood

I spend my entire work day in front of a computer drafting financial analysis reports. By the end of the day I'm normally hopped up on coffee and junk food and feeling really spent. I've been taking Umzu blood flow support for three weeks now. I only drink one cup of coffee in the morning instead of 10 cups per day. I'm more alert mid afternoon and I'm religiously drinking water. Since the shut down of gyms I've made it a point to walk at least four times per week. This product has changed my life. My energy levels are higher. I'm sleeping well. I don't have that mid-afternoon lull anymore. I'm a customer for life!

My Review of Redwood

I am 65 years old. I am a health fanatic to put it lightly. Anything to give me an extra level of blood flow health would be welcome. That said, I decided to give Redwood a try. After only 10 days of taking the product as instructed (3 pills twice daily), I knew, then, I had found what I had been looking for. I decided to go on a monthly auto-ship. This product delivers! I awake with erections every morning and wake up at night with an ********. Because of the new level of blood flow through my body, I now experience new levels of instense ****** explosions. I am looking forward to seeing my doctor for my blood pressure results, too. Thank you Redwood for your wonderful natural and healthy product that gives me back my so much needed ****** confidence!

Something changed,....

63yo with Multiple Sclerosis from the flu shots that I was forced to take in the Army, now 100% disabled/unemployable,..., but not dead! LOL!!!! In April2020 "something changed" I was beginning to feel a bit better, stronger in ways, and libido was stirring after years of NOT. May2020 I saw my Hormone doc , was taking Testosterone to fight the MS- yes it really has helped me keep a pretty normal life in spite of the MS. BUT I had not had T-therapy since DEC2019 from the C19 keeping me from the doctor. So I did not use the new script of T-gel and the new script of estrogen blocker and both went in the trash when I got home. With no T therapy since Jan2020,.., I was 1200 of 1000 T points and my estrogen was a whopping 138 in the MAY2020 visit! I saw myself entering the Valley of the Dolls and found this great line and took the Test-bundle. Just last week I saw my doc,..., Test was 340T and my estrogen was 34! My last blood pressure was 145 over90 and now it is at 110 over 68. No man boobs, no Testosterone overload, clear head, have finished 13 projects I had started over the past 12 years in the rabbit hole of MS. I feel "good,..., like really good" and when I heard the lab results this last visit I told my doc I was off the T since Jan2020. Told him how I wanted to run the treatment,..., umzu,..., and he agreed and he is a great guy- he helped me figure out the T amounts the past 11 years to battle my MS but my body has started making my own again. I "can not" say enough about this line. The D3 also has cleared up my rare GROVERS Disease and where I was having 2-3 very painful attacks a month, I have not the last 7 weeks of my using the D3 and my back is clear and smooth like it was 4-5 years ago before getting this condition as well. Great Job Christopher! 63yo-MS since 1992. while on (9 weeks now) umzu: from 111KG to 93kg! low Bad cholesterol, Testosterone-estrogen ratio much better, Energy, libido, clarity, "happiness" all out the roof from how the last 12 years have been. AND that new pre-workout drink is just GREAT! (makes the original Jac3D look like Candy Cane Lane with out all teh jitters! LOL!) ZERO BPH in 3 weeks after 6 years of it! (I'm out with the rest of the old Hounds!) LOL!!!!

It has been good. I feel like my BP is slightly better and an improvement in perfomance in the bedroom. I'm 62, no meds, enjoying a healthy relationship with my wife 2 to 3 times a week. Occasionally multiple times in 24hrs. What's to complain about??? Thank you.

Stacking Redwood with Testro RX

Excellent. I’m 51 and I’ve been working out consistently for a long time. I recently started stacking Redwood with Testro RX and it feels like it’s taking my fitness level to a whole new level. My muscles feel more full along with leaner body composition. Great products!

Best Supplement I've EVER Had!!!

I researched this product at nauseum! Finally, I ordered a 3 month supply. I started taking the product and I know more natural energy,better mood,and my blood pressure when down to 104/74! I know results may vary, but if your on the fence about thinking of trying this product. In my opinion, please don't hesitate to try this amazing product! I'm not a believer and a user for life!

Feel good taking this product.

Feel good taking this product. If I ordered the testro-x would I still be able to take the redwood? And if I can what would be the best way to take them?



Hi Carlos, yes you can take both Redwood and Testro-X together. In fact, thousands of our male customers are currently doing that with great results since you're optimizing both your hormones & blood flow at the same time. The double whammy. For taking them, I recommend taking the first dose of Redwood in the morning, then the Testro-X after dinner with the second dose of Redwood. - Chris

Redwood Improves My Qi!

I've been taking Redwood Nitric Oxide Booster for over two months now. Approximately two weeks into the product I noticed an improved sense of wellness and my breathing seemed more alive (if that makes any sense). At any rate, I love that the product is free of fillers and cheap ingredients found with so many so called natural supplements. Give it a try! I think you'll become a quick fan like myself. Blessings, Kevin
