UMZU Redwood Review

UMZU Redwood Review


UMZU Redwood is a dietary supplement designed to support circulation and blood flow by boosting nitric oxide levels in the body. The product contains a blend of natural ingredients, including vitamin C, garlic, horse chestnut extract, pine bark extract, and casein hydrolysate. These components work together to provide various health benefits, such as improved energy, sexual stamina, lower blood pressure, better mood, and warmer hands and feet.

Ingredients Breakdown

  • Vitamin C and Garlic exhibit potent antioxidant activity, supporting nitric oxide production and boosting immune system functioning.
  • Horse Chestnut Extract is known for its potential to improve blood circulation and has been used to treat chronic venous insufficiency, although its safety profile requires more research.
  • Pine Bark Extract contains antioxidants that may help manage blood pressure and cardiovascular disease, though evidence is limited.
  • Casein Hydrolysate from cow’s milk may normalize blood pressure, but studies are mixed and depend on the population.
  • L-Leucine, an essential amino acid, supports muscle growth but does not boost nitric oxide and might even block its formation.

1. Vitamin C

Vitamin C is a potent antioxidant that plays a crucial role in the body. It helps protect cells from oxidative stress, contributes to collagen synthesis (important for blood vessel health), and has been shown to improve endothelial function, which is vital for proper blood flow. Vitamin C can also regenerate other antioxidants within the body, including vitamin E. Additionally, high dietary intakes of vitamin C have been associated with a reduced risk of cardiovascular disease, although the evidence on supplementation specifically for improving circulation is more mixed.

2. Garlic

Garlic is well-regarded for its cardiovascular benefits, primarily due to its sulfur-containing compounds like allicin. Research suggests garlic can help lower blood pressure, reduce arterial stiffness, and improve overall cardiovascular health. Garlic has been shown to have a positive effect on nitric oxide synthesis, enhancing vasodilation and thus improving blood flow. Its antioxidant and anti-inflammatory properties also contribute to its heart health benefits.

3. Horse Chestnut Extract

Horse chestnut extract is often used for its venotonic effect, meaning it can increase the tone of veins, improving their ability to push blood back to the heart. It’s particularly noted for its use in treating chronic venous insufficiency (CVI), a condition characterized by pooling of blood in the veins of the lower legs. The active compound in horse chestnut, aescin, has been shown to reduce swelling, pain, and fatigue associated with CVI. While its direct impact on blood pressure and heart health is less clear, its efficacy in enhancing venous circulation is well-supported.

4. Pine Bark Extract

Pine bark extract, particularly from the maritime pine (Pinus pinaster), contains bioflavonoids and proanthocyanidins that have strong antioxidant properties. Studies suggest it can improve blood flow and reduce leg pain and heaviness in individuals with chronic venous insufficiency. There’s also evidence that pine bark extract can lower blood glucose levels and improve endothelial function, further supporting circulation and cardiovascular health. Its benefits in terms of erectile dysfunction and diabetes management also highlight its role in improving vascular health and nitric oxide production.

5. Casein Hydrolysate

Casein hydrolysate contains bioactive peptides with potential antihypertensive effects, likely due to their influence on the angiotensin-converting enzyme (ACE), which plays a role in blood pressure regulation. These lactotripeptides (found in fermented milk products and supplements like casein hydrolysate) have shown blood pressure-lowering effects in some populations, although the research is somewhat mixed, and it appears that response may vary based on genetic factors and existing health conditions.

6. L-Leucine

L-Leucine is an essential amino acid important for protein synthesis and muscle repair. While it’s popular among athletes and bodybuilders for its role in muscle growth, its direct impact on nitric oxide production is less clear. In fact, some evidence suggests that L-leucine might block the formation of nitric oxide, which would not support its inclusion in a supplement aimed at boosting nitric oxide levels. However, its benefits for muscle health could indirectly influence circulation through improved muscle function and metabolic health.

In summary, each ingredient in UMZU Redwood contributes to its overall goal of improving circulation and heart health, though the mechanisms and efficacy can vary. While some ingredients have strong evidence backing their use for vascular health, others may offer more indirect benefits or require further research to fully understand their impact. Always consult with a healthcare professional before starting any new supplement regimen, especially if you have existing health conditions or are taking medication.

How to Take UMZU Redwood

The recommended dosage is three capsules twice a day, ideally taken with food and water. For those who exercise, taking one of the servings before working out can boost endurance and performance. However, the product contains milk protein, making it unsuitable for individuals with a dairy allergy or intolerance.

Efficacy and Safety

While UMZU Redwood may offer benefits in terms of circulation and nitric oxide production, some of its ingredients, like horse chestnut seed extract and pine bark extract, lack extensive evidence for efficacy and safety. The supplement might not be suitable for everyone, especially those with specific health conditions or taking certain medications. Consulting with a healthcare professional before starting any new supplement is always advisable.

Potential Drawbacks

Some users might experience mild side effects due to the ingredients, such as digestive upset, headache, dizziness, and itching. The supplement’s safety for pregnant or nursing women, immunocompromised individuals, and those with dairy allergies or intolerances has not been established.


UMZU Redwood offers a natural approach to improving circulation and nitric oxide production, with some users reporting positive effects on their energy levels, blood flow, and overall well-being. However, the efficacy of some ingredients is not well-supported by research, and there is a potential for side effects. It’s important to weigh these factors and consult with a healthcare professional before incorporating UMZU Redwood into your regimen.
