With that being said, let’s dive into the article.

Improved circulation in turn can improve your mood, prevent inflammation of blood vessels, and may provide harder erections. UMZU Redwood can also improve your immunity.

Besides the claimed benefits by UMZU for Redwood, we also found some other benefits mentioned by its users. One such benefit was, it helped them deal with cold hands and feet, and they felt warmer after taking it.

Also, UMZU Redwood helped the majority of users with their workout and training in Gym.

UMZU Redwood Manufacturer

Most of you here would be familiar with the manufacture of UMZU Redwood. The manufacturer’s name is UMZU itself.

The company was started by Christopher Walker who was a neuroscience student diagnosed with a tumor in his pituitary gland. This deteriorated his health, which is how UMZU’s story started.

Redwood is the star product of UMZU. Besides this there are UMZU also manufactures, UMZU zuPOO and Floracil50. These products have gained almost equal level popularity as the Redwood.

UMZU zuPOO is a gut and colon cleanse supplement while its Floracil50 is a powerful probiotic formula.

How Does UMZU Redwood Actually Work?

With the help of natural ingredients like garlic and Vitamin C, UMZU Redwood may improve Nitric Oxide levels in your system. 

Nitric oxide causes dilation of your arteries and veins. This dilation leads to improved blood flow in your circulatory system. 

For those who have high blood pressure problems, UMZU Redwood can help lower their blood pressure. High blood pressure is mostly caused due to constricted blood vessels.

In addition to improved circulation,  Redwood can provide some sexual and libido-related benefits. These benefits are also accredited to its ability to improve blood circulation.

That was all about the working of UMZU Redwood.

UMZU Redwood Ingredients 

The UMZU’s Redwood Nitric Oxide booster contains a blend few natural extracts to help improve your circulatory system.

Here’s the list of active ingredients contained in UMZU Redwood. A review of these is what lets you know the real-life efficacy of this circulatory support supplement.

Ingredients in UMZU RedWood:

Vitamin C (as Ascorbic Acid), Garlic (Allium Sativum) Root Odorless Powder, Horse Chestnut (Aesculus hippocastanum) Seed Extract, Casein Hydrolysate (Lactotripeptide VPD, IPP from NZ grass-fed cow’s milk), Pine (Pinus pinaster) Bark Extract, L-Leucine.

Let’s explore the potential of each of these ingredients used by UMZU and know their doses per serving. 

1. Vitamin C (as Ascorbic Acid); 1000mg

The majority of the portion of UMZU Redwood is covered by Vitamin C that acts as an antioxidant and reduces oxidative stress. 

Generally known as Ascorbic acid, Vitamin C is important for some critical functions. It is necessary for wound healing, proper immune functioning, and healthy cartilage, bones, and teeth maintenance.

A 2016 review shows, Deficiency of Vitamin C has an association with increased mortality risks from cardiovascular disease.

Vitamin C administration along with inorganic nitrate may enhance nitric oxide production. However, there’s no inorganic nitrate used in UMZU Redwood.

Small studies have shown Vitamin C can lead to an increase in Nitric Acid bioavailability.

Overall, Vitamin C presence provides UMZU Redwood the ability to reduce oxidative acid and improve Nitric Oxide production. Still, Vitamin c lacks strong evidence for improved NO synthesis.

2. Garlic (Allium Sativum) Root Odorless Powder; 300mg

UMZU on the product page of Redwood mentions Vitmain C in combination with Garlic improves N.O. output drastically (by 200%).

A recent 2020 Review of Garlic on hypertensive patients showed Garlic to be effective at lowering blood pressure. It also showed Garlic was able to improve arterial stiffness and had a higher safety profile.

The presence of Quercitin (active compound) provides garlic with potent anti-inflammatory properties. 

Also, quercetin restores/regulates Nitric Oxide production and protects against heart disease as a result of stress.

Overall, Garlic root in Redwood may induce muscle relaxation, vasodilation and improve circulation.

3. Horse Chestnut (Aesculus hippocastanum) Seed Extract; 250mg

It is a tree native to Southeastern parts of Europe. Traditionally seed of Horse chestnut fruits was used for leg cramps, joint pain, GI problems, and other conditions.

Each serving of UMZU Redwood contains 250mg of Horse chestnut seed extract. UMZU tells this ingredient to help circulatory conditions like varicose veins and poor blood circulation.

Horse chestnut is mostly preferred for conditions like vascular fragility and chronic venous insufficiency(CVI). 

CVI is a condition in which the veins in your legs don’t allow the flow of blood back to your heart. This could lead to swelling and pain due to inflammation. 

Horse chestnut is effective at treating pain and inflammation caused by CVI.

Overall, the working of the Horse chestnut is still not completely clear. But, it can have some benefits related to blood flow improvement and is effective for CVI too. 

4. Casein Hydrolysate (Lactotripeptide VPD IPP from NZ grass-fed cow’s milk); 125mg

Hydrolyzed Casein protein or casein hydrolysate are proteins usually found in cow’s milk as well as other dairy products.

Casein proteins are also high in calcium content which may provide benefits related to vascular, muscle, and bones health. 

These proteins may have significant benefits for normalizing blood pressure. 

A 2011 study found Casein to lower blood pressure in rats with hypertension. Also, it showed, Casein hydrolysate can improve blood vessel functioning and circulatory health.

Though casein still lacks satisfactory evidence showing its efficacy in human subjects.

5. Pine (Pinus pinaster) Bark Extract; 100mg

UMZU Redwood also has 100mg of pine bark extract per serving. 

Generally, pine bark is high in antioxidants and is used for regulating blood sugar levels and improving erectile dysfunction.  

However, most studies say pine bark doesn’t help patients with cardiovascular risk factors, but it may cause small blood vessel dilation in CVD patients.

Animal studies on pine bark found it to have a vasodilatory effect which in turn can improve blood pressure. 

A 2007 study found Pycnogenol (Pine Bark extract), to have a direct impact on increasing Nitric Oxide production. Also, daily intake of pine bark can improve your circulation.

6. L-Leucine; 75mg

UMZU Redwood also contains an essential amino acid L-leucine. Amino acids are critical for protein synthesis in our bodies. 

The l-leucine dietary supplements are mostly taken by bodybuilders as it is believed to support muscle growth. (In case you didn’t remember, it is also available in D-Bal)

L-leucine may stimulate HGH production as per some studies. It may also have some antihypertensive effects that can help patients with hypertension.

However, there’s no link between L-leucine and improvement in Nitric oxide level. in fact the reverse is seen during studies.

It is my healthier pre-workout solution as it makes me energized, focused, alert, clear-minded, and adds a major pump. Yes, you will look vieny guys”– Adrian.

“The product seems to work well for athletic purposes (I could feel it working shortly after taking in increased blood flow to already prevalent areas, warmth, vascularity), however, it has had no effect on the loss of blood flow in my fingers when it gets even remotely cold. Additionally, I’ve noticed no effect on mood, etc”– Andrew C.

“My urine had blood in it every day I took this. I had pain in my abdominal area. The minute I stopped taking this the blood in my urine stopped. I waited three days and took it again and the blood in my urine came back. I suggest you take this at your own risk”– Mark s.
