About UMZU 

UMZU Natural Supplements Review

UMZU makes effective, natural hormone and wellness supplements that restore healthy balance to the body. Their line of supplements contains clinical doses of quality ingredients tailored to the needs of both men and women. 

One study[1] demonstrated that over half of US adults used some kind of herb or supplement to treat a specific condition they suffered from. That’s a lot of people! If you’re someone who deals with a bothersome condition that isn’t necessary to treat with traditional western medicines, natural supplements might be the route for you.

UMZU has a following of 63k on Facebook and 45k on Instagram. UMZU founder Christopher Walker’s Instagram account, on which he heavily promotes his brand, boosts those more modest numbers with 322k followers

This UMZU natural supplements review will take an in-depth look at the brand and its bestselling supplements, customer reviews, perks, promotions, and more to help you decide if these products are the right choice for you.

Overview of UMZU 

UMZU Natural Supplements Review

UMZU first began taking shape when neuroscience student Christopher Walker was in university. Diagnosed with a tumor on his pituitary gland that caused hormonal imbalances, Walker researched clinical studies to come up with a natural way to combat his condition. 

Although he was not able to get rid of the tumor, Chris eventually devised a method to cure his imbalances. He published his findings and began building a community of men who got results from using the same formula. 

Since sourcing the ingredients proved tricky for many, Chris began getting requests to create a supplement of his own. During this process, he also heard that many women were seeking natural remedies for hormonal imbalances as well. 

UMZU Natural Supplements Review

Partnering with Darren Crawford and Mike Dobson, Chris founded UMZU in Boulder, Colorado, in 2015. UMZU’s natural supplements reflect the brand’s core belief that, “the human body is a self-healing organism that when supported correctly cannot only heal itself but allow itself to thrive.”

Today, UMZU has an expansive product line and its own diet system, the UMZU Thermo Diet. Before we delve into those, this UMZU natural supplements review will give a topline view of the brand’s highlights:


  • A variety of supplements that provide several desired health benefits 
  • Made from natural, high quality, research-backed ingredients
  • Transparent approach
  • Learning center provides more information on their products
  • 15% discount when you subscribe
  • Earn points on every purchase to use towards rewards
  • International shipping options
  • 60-day money-back guarantee 

What is UMZU?

UMZU Natural Supplements Review

UMZU is a natural supplement company that helps men and women reclaim their hormonal balance.

These supplements are born from science and experience, formulated with research-backed ingredients.

UMZU products have brought balance and real results to many people struggling with hormonal and other health issues like testosterone levels, brain function, hair growth, and more. 

Many of their supplements come with one-time purchases of 30-day supplies, which is over 180 tablets/capsules to keep your health issues at bay. But, subscriptions are offered for those interested in long-term use.

Are UMZU products safe? 

UMZU Natural Supplements Review 1

UMZU products are generally considered safe, but you should consult your healthcare professional before starting a new supplement. For example, Redwood increases blood flow, and for that reason should not be used by anyone who uses blood thinners.  

UMZU Vitamins & Supplements Review 

UMZU has created many supplements and pills that work for some unique health issues. From testosterone support, hair growth, and even brain function, this brand has thought of the everyday issues we all face and come up with a healthy solution for each of them. 

This UMZO natural supplements review will now take you through the brand’s most-loved products. So have your credit card ready, some of these supplements may be just what you need to make your everyday health issues a distant memory. 

UMZU Redwood Review

Aptly named for its ability to increase circulation to both the upper and nether regions, the UMZU Redwood blood flow dietary supplement promotes warmer extremities, more energy throughout the day, and increased performance in the bedroom. 

With ingredients including Vitamin C, garlic[2], horse chestnut extract, and pine bark extract[3], UMZU Redwoodpills increase blood flow, therefore improving circulation and helping overall performance.

Flow through your day (and night) better with a 30-day (180-capsule) supply of Redwood for $40 for a one-time purchase, or $34 with a subscription.

UMZU Testro-X Review

Harnessing the power of minerals like zinc and boron with a blend of naturally stimulating vitamins and herbs, this UMZU supplement enhances your energy, stamina, and power

Zinc[4] is required in high enough levels for the pituitary gland to release the hormones responsible for stimulating testosterone production. So don’t be surprised if you suddenly start killing it in the gym. 

Lift those T levels up where they belong with 30 days’ worth of Testro-X for $55, or get the 15% discount when you subscribe and score it for $47.

UMZU zuPoo Review

Brace yourself: on their website, UMZU cites the fact that the average American carries 5 to 20 extra pounds of poop in their intestines daily. That alone is enough to inspire a colon cleanse, and UMZU’s zuPOO can help you achieve it safely and naturally.

This 15-day cleanse is not for the faint of heart: users typically find themselves going to the bathroom up to 5 times per day for the first 24 to 48 hours, but without any pain or distress.

Using natural ingredients like slippery elm and aloe, zuPOO cleans your digestive tract and supports a newly clean and healthy lifestyle. Slippery elm has been shown in one study[5] to improve symptoms of Inflammatory Bowel Disease.

Make sure to follow up with probiotics to support your intestinal health. Get the ultimate in natural waste removal for $30, or $26 with a subscription. 


A blood sugar imbalance can wreck your energy and mood. Sensolin helps you control your blood sugar levels naturally and reduce appetite and cravings. It accomplishes these things thanks to ingredients like chromium[6], which has been shown to improve metabolism in those with suboptimal chromium levels. 

It can also improve digestion, thanks to ingredients like cinnamon. One study[7] showed cinnamon modulates the insulin response, which helps lower blood sugar levels.

Head off that afternoon crash and save yourself that trip to the vending machine with Sensolin, in a 90-capsule bottle for a one-time purchase price of $50. 


For those who don’t know that our intestines are filled with bacteria, well, now you do.

But that bacteria isn’t all bad: without the good bacteria to help digestion and fight off the harmful bacteria, we may experience constant stomach issues, like bloating and gas. That’s where UMZU’s Floracil50 comes in.

This extra-strength probiotic contains 50 billion CFUs (colony-forming units) from 8 handpicked bacterial strains (which sounds gross if you’re new to probiotics, but please keep reading). These bacteria help to support gut function and digestion[8].

In addition, this product also helps with immune system function. The gut guards against outside offenders, like bad bacteria. Keeping the gut healthy with probiotics can improve its’ natural barrier function.

Once you’ve cleansed your system with zuPOO, show your gut some love with a 30-day supply of Floracil50, which goes for $45 for a one-off purchase and only $39 with a subscription. 


Stress attacks our brain, our immune system, our gut, our skin, our hearts… it’s everywhere, all the time.

But, in addition to heart-healthy exercise, immune-boosting foods, and those small moments of peace, UMZU’s Cortigon can help us fight off this definitive malady of the modern world. 

With its blend of herbs, vitamins, and minerals that are clinically proven to lower cortisol (the stress hormone), Cortigon not only helps naturally lower stress, it also improves brain function, energy levels, and mental clarity.

Among the ingredients in this product are vitamins B6 and B12, which have been shown time and time again to be superpowers when it comes to reducing stress. One study[9] showed vitamin B6, in particular, to be inversely associated with stress symptoms. 

Whatever your stress-reduction routine, you can give it a clinically proven boost with Cortigon for $40. 

UMZU zuACV + Prebiotics Review

Easily affected by stress, food, and medication, our intestinal balance is often compromised, which can lead to several negative health issues[10]

ZuACV + Prebiotics contains gut-boosting apple cider vinegar, which has been shown to help to restore good bacteria[11] to our guts.

This product also helps strengthen our immune system with prebiotic fibers from ingredients like chicory root and fibrous, immune-boosting inulin. Chicory and inulin are important builders of gut immunity by improving gut function. 

Give your gut the right stuff with zuACV + Prebiotics, which goes for $35 for a one-off and $30 for subscribers. 

UMZU Ultimate Hair Restoration Sack Review

For everything you will need for hair growth and some added benefits with all-around health, the Ultimate Hair Restoration Stack provides the brand’s signature supplements including: 

  • Betaine
  • Cortigon
  • Vitamin D3
  • Choline
  • Thyrite

We’ve already gone over the Cortigon supplement earlier in this Umzu Natural Supplements review, so let’s take a closer look at the rest of the products in this bundle in more detail below:


Betaine is a chemical naturally found in the body. A study has shown that betaine supplementation can significantly help with digestion. 

Vitamin D3

Vitamin D3, provided in liquid form by UMZU, is not only a sunshine vitamin but also one used for bone health[12], immune-boosting[13], and hormonal function[14]

Many like to use it for its positive effects on wellbeing, especially during the cold winter times when we are most deprived of the sun’s happy rays. Vitamin D3 is a well-rounded supplement for mental and physical health.


Choline is a nutrient found naturally in some foods, but why would you consume it as a supplement? Choline is converted to a neurotransmitter[15] called acetylcholine in the body, which is responsible for essential nervous system functions like muscle control, mood, and memory. 


Thyrite is for your thyroid, a powerful gland[16] in your neck. Along with thyroid support, Thyrite can prevent hair loss. It is well known that some endocrine disorders, like hypothyroidism, can result in dry, coarse hair and even hair loss[17].  Having a healthy thyroid can also aid in weight loss.


Last but not least, zuCOLLAGEN is UMZU’s special protein powder. Collagen is a natural protein in your body, and when there isn’t enough, your skin elasticity, joints, hair, and nail health can all suffer the consequences. zuCOLLAGEN specifically is a blend of 5 types of collagen to give you a comprehensive protein supplement for your inside and outside beauty.

These supplements are all useful to your health in their own way, but all together they make the perfect hair-growth system.

The brand recommends using all of this daily to provide the body with all of the nutrients needed for stronger, thicker hair and restoring hormonal balances[18], gland functions, and supporting gut health.

Coming with options of different flavors and the ability to leave out the Vitamin D3, the Ultimate Hair Restoration Stack comes for $176 for a one-time purchase and $150 at the subscription price.

UMZU Reviews: What Do Customers Think?

UMZU Review

This UMZU natural supplements review took to the internet to find out what customers are saying about UMZU products.

Below, you will find reviews from the company website, Reddit, and Amazon discussing the brand’s various supplements, their results and side effects, and their prices. 

Cortigon is rated an average of 4.3/5 stars based on309 ratingson the company website. Commenters praised the product’s immediate and lasting results in combating stress.

One UMZU supplement review describes the user’s experience with the product:

Before taking cortigon I had very bad anxiety…I noticed a massive difference after the first day of using it and by the third day my anxiety had pretty much disappeared…[after a month], I am still noticing a continuing and consistent change in how I feel and my energy levels.” 

As far as negative reviews go, the main concern was that although they were pleased by the results, many customers feared that they wouldn’t be able to sustain the treatment due to the high price. 

UMZU Sensolin reviews on the brand website give the blood sugar support a stunning 4.2/5 stars from 474 ratings, none giving less than 3 stars.

UMZU Testro X reviews return that same sterling rating with an astonishing 66% 5-star rankings out of 2,694 total.

A Reddit thread discussed the effects of UMZU Redwood pills, noting how they remedied issues with cold extremities and aided in weight loss:

I’ve been using Redwood for 2 months and it works…I chronically suffered from cold extremities and that is a thing of the past. Also paired with some mild bodyweight exercise and some diet modifications it will help the fat melt off.” 

On Amazon, 8,168 UMZU Redwood supplement reviews give the product an average of 4.3/5 stars.

One customer spoke about how it helped increase his circulation and boost his energy levels: “I also feel like my blood is flowing well and feel a little fatigue when not using it.” 

We say it all the time: body chemistry is a tricky thing, and especially where dietary supplements are concerned, not everyone is going to experience the same benefits.

Even the most highly touted products may not have what your body needs, so it’s always about finding what works for you.

Is UMZU Worth It?

UMZU Natural Supplements Review

This UMZU natural supplements review has read enough customer reviews to see that, for many users, UMZU supplements are making a huge difference in their lives.

The convenience factor is also a huge plus, as the combined supplements eliminate the necessity of sourcing five or six different vitamins and minerals yourself.

Does Redwood actually work? According to thousands of customers, yes. Although these UMZU supplements can be pricey to keep consistently, if you can afford them and they improve your life, this UMZU natural supplements review says they are worth the buy. 

One possible pricing solution is a subscription, which helps you save money on UMZU products and which you can cancel at any time. If you’re still on the fence, UMZU also offers a 60-day money-back guarantee.
