The world of dietary supplements is rife with an endless array of product offerings, the majority of which tout significant boosts to your health markers and promise to be the end-all to your nutrient deficiency issues.
This trope is even magnified when you narrow in on male health supplements.
Here, you will find hundreds of specific concoctions that claim to increase everything from energy levels to productivity, workout performance, sexual performance, and sexual health.
The Redwood from Umzu is one of the many options on the market that takes a more holistic approach, offering a formulation created to improve blood circulation, and by extension, all aspects of your physical, mental, and sexual health.
However, promising the world in terms of health benefits is one thing. Delivering on that promise is another. Does the Umzu Redwood supplement mix work, and is it the right pick to match your specific needs?
What is Umzu Redwood
Umzu is a natural supplement product company (founded by a graduate of Neuroscience and fitness influencer Christopher M. Walker) that offers a line of wellness supplements that targets comprehensive markers instead of specific functional groups.
With these multi-prong offerings, the company aims to produce supplements that improve your overall health, boost general function, and help you thrive in everyday life activities.
Their Redwood product, their most popular offering, is one such multifaceted supplement mixes that claims to help boost nitric oxide presence in the blood. As a result aids in improving blood circulation, circulatory health, and the release of critical hormones like human growth hormone and insulin.
Nitric oxide is a naturally occurring compound in the body that is partly responsible for the relaxation of the muscles and dilation of the blood vessels, regulating the flow of blood and nutrients through the body.
When the body contains sufficient nitric oxide, the walls of our blood vessels expand, stimulating an increased rate of blood flow and allowing more efficient transportation of oxygen and nutrients to your muscles, organs, and all your body’s extremities.
With Umzu Redwood, this company aims to provide a formula that effectively stimulates the natural production of nitric oxide in the body to help improve circulatory function.
Umzu markets this offering as a possible stimulant of circulatory-related benefits like increased performance with exercise and sex and improved blood vessel and heart health.
However, Umzu Redwood, like most other similar “nitric oxide-boosting” supplements, does not contain any nitrous oxide.
Nitric oxide 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 that line the interior walls of our blood vessels.
However, with Umzu Redwood, you also get a host of other natural extracts that the company touts as the perfect recipe for boosting all other circulatory function aspects. With this product, Umzu aims to provide a formula that helps prevent diseases and boost both circulatory and overall health.
The Active Ingredients (and their effects)
Umzu Redwood contains a blend of natural extracts to stimulate the natural production of nitric oxide by your blood vessels. The active ingredients included in the mix are:
Umzu Redwood also contains purified water and other inactive ingredients like rice powder, milk, and gelatin— that may be possible allergy risk factors.
The smallest entry on the ingredient list by mass may also be the most critical addition to this formulation. While this supplement contains only 75mg of L-leucine per serving, this amino acid’s metabolic importance put it up there as one substantial addition to the mix.
L-leucine is an amino acid that plays a critical role in protein synthesis within the body.
Similar to the role of other amino acids, leucine can also feature in ATP generation, providing energy for the life-sustaining functions of the body’s cell. However, L-leucine’s role extends further still.
L-leucine can help regulate a host of other crucial cellular processes like tissue regeneration, fat production, and metabolism.
There is limited research available on the direct impact L-leucine has on athletic performance and male sexual health. However, one scientific review into the potential effects of L-leucine supplementation indicates promise in its ability to promote fat loss, encourage the development of lean muscle mass, and reduce the incidence of metabolic diseases like diabetes mellitus.
Umzu also suggests that L-leucine may help with overall cardiovascular health and help prevent related diseases. However, there inadequate scientific evidence indicating the amino acid overtly or covertly performs this function.
Each serving (3 tablets) of Umzu Redwood contains 300mg of garlic root odorless powder, a substance with potentially massive health benefits.
Garlic contains a host of compounds that can provide an extensive positive impact in many health areas, help boost various aspects of bodily function, and aid in fighting seasonal ailments like colds and more chronic conditions like hypertension and heart disease.
However, one factor that is key to garlic’s inclusion in the Umzu Redwood formula is its impact on nitric oxide production and regulation.
This research study shows that garlic contains nitrates and polysulfides that can help regulate the deployment of nitric oxide in the blood vessels, which induces muscle relaxation, increases the blood vessels’ dilation, and enhances circulation. These compounds also play a crucial role in hydrogen sulfide production—a vascular gasotransmitter that helps regulate many cellular functions.
Furthermore, one meta-analysis of the effects of garlic on blood pressure in hypertensive subjects found that this superfood can lower cholesterol levels and reduce blood pressure levels.
Other potential benefits attributed to garlic by a host of studies include:
- Boosting white blood cell production and immune function.
- Providing prebiotic properties and promoting healthy gut microbial presence.
- Treating sulfur deficiencies.
While there is no clear scientific evidence on the impact of vitamin C on blood flow or the release of nitric oxide, this vitamin is always an excellent addition to any nutrient mix that promotes improved health and optimal body function.
The impact of vitamin C on health includes its role in:
- protecting and boosting the immune system
- acting as an antioxidant that protects your frame from free radical damage
- and serving essential roles in various critical body functions like bone formation, tissue maintenance, wound healing, metabolism, and cholesterol and amino acids’ processing.
Furthermore, several observational studies indicate that vitamin C supplementation may be associated with better cardiovascular health and a lower risk for developing cardiovascular disease.
A 2003 study conducted on rats also shows a considerable jump in nitric oxide synthase activity after around seven weeks of vitamin C supplementation.
Pine Bark Extract
Pine bark extract is one ingredient of Umzu Redwood with enough scientific evidence to back its direct impact on nitric oxide production.
This plant extract contains bioflavonoids (taxifolin and catechin) which help regulate the release of nitric oxide in the blood vessels. The presence of these bioflavonoids helps to stimulate increased production of nitric oxide by the endothelial cells, which intensifies the dilatory effect of the blood vessels to enhance blood circulation.
Pine bark extract is a plant extract from the bark of French maritime pine. Pink bark extract is available as standardized standalone supplement options like Pycnogenol.
Pine bark extract’s potency in preventing cardiovascular diseases and increasing the circulatory system’s overall health also has some research backing.
In one 2018 review of 5 separate trials, the researchers discovered that sufficient supplementation with pine bark extract consistently helped reduce the levels of several biomarkers of cardiovascular disease presence and onset.
Similarly, in a 2016 study with 70 menopausal women, the researchers ended up with comparable results. After placing the test group of 35 women under pine bark extract supplementation for eight consecutive weeks, the researchers discovered that the participants in this group experienced a marked reduction in cardiovascular disease markers like triglycerides and cholesterol levels, blood pressure, fasting glucose levels, and plasma free radicals compared to the control group.
Horse Chestnut Extract
Horse chestnut is a flowering plant native to Southeast Europe that is a common feature in many oral and topical herbal remedies as an “all-curing wonder plant.” However, its inclusion in the Umzu Redwood formula is most likely due to one particular constituent.
Horse Chestnut Extract contains an active ingredient, escin, which appears to impact blood circulation and vascular health positively.
While there is still limited research into how and why this compound works, the available preliminary studies indicate that it may help seal leaking capillaries, inhibit the release of enzymes, and prevent other physiological occurrences that can damage the blood vessels’ structure, improve the elasticity of arteries and veins.
Casein hydrolysate is a protein present in milk and other dairy products that may provide considerable benefits to circulatory health.
The available clinical research into the effect of this amino acid found that it may help reduce blood pressure and increase nitric oxide expression in the blood vessels.
In one study that involved casein hydrolysate supplementation in hypertensive rats over six weeks, the researchers found that after the test periods, the rats undergoing the treatment showed a marked reduction in blood pressure. The test rats also showed a significant improvement in blood vessel function and other heart and circulatory health markers.
A smaller 2005 (preliminary) study that included 133 volunteer human subjects also produced comparative results.
Note: A considerable amount of human studies is still required to verify any claims of casein hydrolysate’s effectiveness for boosting heart and circulatory health.
Proper blood flow is critical to life. The bloodstream is responsible for transferring oxygen to all parts of the body, and oxygen is key to creating the energy that fuels our living processes.
With their Redwood supplement mix, Umzu claims to provide a formula that helps to supercharge this process, increasing blood flow and oxygen distribution and, consequently, providing more fuel for our daily activities and improving our overall health.
Potential benefits the manufacturer attributes to the use of this formula include:
- Improved blood flow
- Increased stamina during exercise and other strenuous activities
- Bigger “pumps” from exercise due to increased blood flow to the muscles
- Lower levels of fatigue
- Stronger erections and enhanced sexual performance
- Boosted immune function
- Reduced risk factors for circulatory health conditions like hypertension and blood clots
Does Umzu Redwood Work?
Few formulas on the market are effective at improving nitric oxide presence in the blood as Umzu Redwood.
This segment of the market is heavy with hogwash. Redwood does well to set itself apart from the pack by incorporating a lineup of all-natural ingredients with varying levels of scientific evidence to back their efficacy in boosting nitric oxide expression.
Hence, if you want to improve nitric oxide production in your body and, by extension, enhance your blood flow and experience some of the promised benefits, the Umzu Redwood formula is one of the best routes you can take.
Plus, this supplement mix has the reviews to back its claims.
Several users of the product, especially those in their 50s or older, reported a multitude of benefits, including an improved sense of wellness, better mood, lower blood pressure, less fatigue, more stamina, improved joint health, a return of the morning wood, and enhanced bedroom performance.
However, like most supplements of this nature, the degree of results may vary significantly from individual to individual.
Side Effects and Safety Concerns
For a supplement that works to impact blood flow and circulatory health, Umzu Redwood is a markedly low-risk formula. The supplement mix contains an all-natural formulation free from synthetic and proprietary ingredients and fillers.
Hence, there is a meager chance of experiencing any adverse reactions when using the product in the right dosage.
The supplement is generally considered low-risk, safe to use, and an excellent risk-free option for improving blood flow and boosting circulatory function.
However, Umzu Redwood, like other forms of supplements for circulatory health, can pose a risk of excessively lowering your BP when combined with blood pressure meds and other related drugs.
Hence, people with pre-existing cardiovascular issues and those currently undergoing heart-related medication should consult with their health practitioner before incorporating Redwood into their wellness routine.
