Overview of UMZU Redwood

UMZU Redwood Review

UMZU was created by Christopher Walker, who was diagnosed with a tumor on his pituitary gland years ago, causing severe hormonal imbalances in his body.

Being a neuroscience student at Duke, Walker used his knowledge and research to create a natural hormone formula that was different from synthetic solutions with numerous side effects. 

After restoring his hormonal health and publishing his findings, he was able to build a trusted community of like-minded people following the path to natural hormonal health.

Partnering with Darren Crawford, Walker founded UMZU in Colorado in 2015, and instead of focusing only on fixing symptoms, they are on a mission to help people by getting to the root cause of their illness, with a thoughtful, trusted, and holistic perspective.

UMZU’s goal is to provide the necessary tools to overcome micronutrient deficiencies and hormonal imbalances for optimal energy production throughout the body. They work towards this goal by providing the knowledge and resources to support their community to thrive.

Walker has a personal Youtube channel with 193k subscribers, where he promotes UMZU products and missions while sharing educational videos.

In this UMZU Redwood review, I’ll look at this naturally sourced supplement that will promote better blood flow and circulation in your body. I’ll walk you through the ingredients, its recommended usage, price and discount options, customer reviews, and more so that you can decide if this blood circulation enhancer is worth it.

UMZU Redwood Review

In the next section of this review let’s take a good look at what it has to offer for your health. I’ll go over the UMZU Redwood ingredients and benefits to better understand their function.

UMZU Redwood Review

UMZU Redwood promises more energy and stamina, warmer hands and feet, increased libido, stronger immunity, and improved mood as it uses a mechanism based on the body’s own nitric oxide production. It takes a holistic approach, created to improve all aspects of your physical, mental, and sexual health.

Christopher Walker promotes UMZU Redwood on his personal Youtube channel as the best supplement to lower blood pressure, increase nitric oxide, and get more vitamin C. He introduces it as a combination of simple and precise but effective ingredients based on nature’s innate wisdom for blood flow. 

Now, the first question that may come to mind might be why someone would consider taking a supplement that supports blood circulation.

According to both traditional and modern medicine, proper blood circulation[1] is one of the most significant role players in achieving health and wellness. Blood, nutrients, and oxygen are able to travel to every part of your body through your circulatory system effectively and efficiently. 

In order for the blood vessels to carry things around smoothly, your body needs nitric oxide. Nitric oxide’s job is vasodilation[2], meaning it relaxes the inner muscles of the blood vessels, causing them to widen and increase circulation

In addition to consuming the building blocks of nitric oxide through a good diet and lifestyle, natural blood-flow-improving supplements are another popular tool to reverse the effects of poor circulation and to achieve and maintain optimal levels of nitric oxide throughout the body.

This UMZU Redwood review found that since nitric oxide is a naturally occurring yet unstable[3] substance, it constantly needs to be replenished. Getting help from antioxidants that fight oxidative stress[4] in the body is one way to do that. 

Antioxidants help decrease the breakdown of nitric oxide and extend its life in your body. Everyone wants more nitric oxide right? I found that the main reason for the use of vitamin C in UMZU Redwood’s formula is to support nitric oxide production and function.

It’s important to bear in mind that most of the vitamin C in this supplement is likely to pass through the body without being absorbed because vitamin C is a water-soluble nutrient. At doses over one gram per day, the absorption of it is lowered to be 50%[5] causing the remaining vitamin C to be excreted from your body.

As you can see on the product’s label, there is also a good amount of garlic in this formula. Garlic[6] has a positive effect on blood pressure and is safe for use in managing high blood pressure. Quercetin[7] in garlic is also another powerful antioxidant that regulates nitric oxide[8] production and protects body organs against stress.

Next up is horse chestnut seed extract. This plant contains compounds that are known to help increase blood circulation. These compounds are specifically beneficial for varicose veins[9] or enlarged, twisted veins[10] on the legs.

Even though the studies are limited regarding the effects of casein hydrolysate on blood circulation, this UMZU Redwood review discovered proteins such as lactotripeptides[11] from cow’s milk are why casein hydrolysate has been considered in this formula. These proteins are believed to normalize blood pressure

Antioxidant-rich pine bark extract[12] is another helpful element in this formula that, as mentioned above, can neutralize the effects of oxidative stress in the body and replenish nitric oxide reserves in your body.

The last UMZU Redwood ingredient I would like to briefly introduce is L-leucine. which is an essential amino acid. Nitric oxide-boosting supplements typically contain amino acids like L-citrulline, L-arginine, and L-leucine that are critical to the synthesis of nitric oxide by the cells of your blood vessels.

Leucine may also help with muscle growth and boosting lean body mass which is the main reason bodybuilders include it in their routine.

Each 180 capsule bottle of UMZU Redwood contains 60 servings and costs: 

  • One time-purchase currently costs $40
  • You can also save 15% if you subscribe to auto-delivery every 30, 60, or 90 days

UMZU offers a 60-day money-back guarantee on the first purchase of all their supplements.

Who Is UMZU Redwood For?

UMZU Redwood Review

All UMZU products can be taken by both men and women. If you are looking for better performance at the gym, increased energy, immunity against disease and focus, improved sexual life, reduced recovery time and fatigue, UMZU Redwood is for you.

What Are the Benefits of UMZU Redwood? 

UMZU Redwood Review

As a nitric oxide booster, UMZU Redwood can support more efficient transportation of oxygen and nutrients to organs and your muscles. This will benefit conditions like high blood pressure and varicose veins.

Other noteworthy benefits of the product are enhanced sexual performance, increased stamina during exercise, more blood flow to muscles during exercise, and reduced fatigue.

How Does UMZU Redwood Work?

UMZU Redwood Review

Your body needs to make nitric oxide with the help of antioxidants like vitamin C and nitrates. Without enough of these building blocks, you will not be able to produce enough nitric oxide[13]. This can directly affect your immunity, circulatory system, and muscle performance. 

UMZU Redwood is a natural research-based solution made with high antioxidant ingredients such as vitamin C, garlic, and isoleucyl-prolyl-proline to increase nitric oxide production, blood flow leading to better bedroom performance, healthy blood pressure, warmer extremities, strong immunity, more endurance, and improved mood. 

What Are the Ingredients In the UMZU Redwood?

UMZU Redwood Review

UMZU Redwood contains: 

  • 1,000mg of vitamin C in the form of ascorbic acid
  • 330mg of garlic root odorless powder
  • 250mg of horse chestnut seed extract
  • 125mg of casein hydrolysate
  • 100mg of pine bark extract
  • 75mg of L-leucine in each serving

Other ingredients on the label are: rice powder, gelatin, and purified water.

Vitamin C is a water-soluble vitamin found in various foods and dietary supplements. It is an essential micronutrient involved in the formation of collagen, and vital for the healing process.

The ascorbic acid used in this formula is a form of vitamin C found naturally in food. Some people with a sensitive gut may find it too acidic and can’t tolerate it in higher doses even though it absorbs well.

Garlic is a bulb-shaped veggie that is a member of the onion family. When cut or crushed, this powerful vegetable releases its potent sulfur compounds that give raw garlic its strong odor and flavor.

Horse chestnut is likely effective in treating some symptoms of chronically decreased blood flow from the feet and legs back to the heart which results in leg pain, varicose veins, swelling, and itching in the legs.

Casein hydrolysate is another name for hydrolyzed casein peptides. Cow’s milk is made up of around 80% casein and this protein gives milk its white color. To make Casein hydrolysate, casein is broken down into its constituent amino acids.

Pine bark extract has been used by indigenous peoples of North America as medicine. Pine trees are native to Portugal, Spain, France, and Morocco. The extract[14] itself is used as an herbal supplement for its antimicrobial, antioxidant, and anti-inflammatory effects on the human body. 

L-leucine is an essential amino acid commonly used in fitness supplements. This amino acid (a building block of protein) cannot be made by your body and you need to get it from your diet. It is important for managing your blood sugar[15], as well as repairing[16] and building muscle.

How to Take UMZU Redwood and Dosage

UMZU Redwood Review

They recommend taking three capsules of UMZU Redwood with food and water in the morning and three in the evening, with about 12 hours in between. People who exercise can take one dose before working out for more stamina, energy, and muscle growth. 

UMZU Redwood Side Effects

Umzu Redwood contains milk protein in the form of casein hydrolysate, so it’s not safe for anyone with a dairy allergy. One other important UMZU Redwood side effect is related to the safety of horse chestnut seed extract and pine bark extract.

These have not been extensively studied. Some side effects linked to horse chestnut seed extract include digestive upset, headache, dizziness, nausea, and itching.

Three capsules twice a day will give your body 2,000mg of vitamin C, which is unlikely to cause issues. But it is important to note that excess vitamin C above an individual’s tolerance will cause digestive upset and diarrhea.

Since some of the ingredients in UMZU Redwood may have a blood pressure-lowering effect, anyone taking blood pressure medication or with cardiovascular disease should absolutely speak with their physician before taking it. 

UMZU Redwood should be avoided by pregnant and nursing women and immunocompromised individuals as some of its ingredients are not 100% risk-free.

It’s always a good idea to check the proper dosing, and risks of a new supplement with your healthcare professional especially if you are on medication.
