What Umzu Redwood Claims Did We Find?

what umzu redwood claims did we find

Redwood is an N.O. supplement that allegedly boosts your body’s nitric oxide levels. It claims this will support blood flow and heart health while increasing your energy and kicking your immune health to a higher degree of function. These purported Umzu Redwood benefits include lower blood pressure, a boost in circulation, better digestion, improved cognitive function, and fat loss.


What are the Umzu Redwood Ingredients?

Redwood by Umzu comes in capsule form. Each three capsule serving provides you with the ingredients listed below, along with the following: Rice Powder, Gelatin, and Purified Water (Capsules).

  • Vitamin C 1,000mg
  • Garlic Root Odorless Powder 300mg
  • Horse Chestnut Seed Extract 250mg
  • Casein Hydrolysate 125mg
  • Pine Bark Extract 100mg
  • L-Leucine 75mg

There is no established %DV (Daily Value) for any of the ingredients except for Vitamin C, which is 1,111% for each serving of Umzu Redwood ingredients.


Does Umzu Redwood Work? Benefits

Vitamin C is the most abundant nutrient in Redwood, at 1,000mg per serving. According to Functional Foods in Health and Disease, this vitamin has numerous health applications at optimal doses between 90-500mg daily, and the risks of higher doses are negligible.

Umzu Redwood contains 300mg of garlic root powder. The Journal of Pharmacognosy and Phytochemistry observed that garlic displays similar antioxidant activity to Vitamin C. That could help boost your immune system.

One of the advertised claims of Umzu Redwood is that it improves circulation. There is 250mg of horse chestnut seed extract in each serving, and this particular ingredient might help with those circulation claims. An article in the Cochrane library found that horse chestnut seed extract proved efficacious and safe when used for short-term treatment of some cardiovascular issues.

Casein hydrolysate is a mix of amino acids, calcium, phosphate, vitamins, and microelements. There is 125mg of casein hydrolysate in each serving of Umzu Redwood. It is a protein found in cow’s milk that is supposed to lower blood pressure by enlarging blood vessels.

Nutrition Research Reviews looked at the current evidence of the effect of milk proteins on blood pressure and vascular function. While concluding that growing evidence demonstrates a positive influence on vascular health, it also identified concerns with the data. The conclusion is that more robust testing is needed before this claim is verifiable.

Umzu Redwood also contains 100mg of pine bark extract. It is an herbal supplement ingredient that purportedly has anti-inflammatory, antimicrobial, and antioxidant properties. Food Science & Technology performed a systematic review of pine bark extract in 2019. That journal’s article highlights pine bark extract’s potential use as an antioxidant in the meat industry and as therapeutic potential because of its anti-inflammatory and antioxidant nature.

Weight Loss

What About Umzu Redwood and Weight Loss?

One of the ingredients in Umzu Redwood is garlic root powder. While it might not burn fat directly, the opinion of Current Nutrition & Food Science is that garlic could potentially lower several lipid metabolism markers associated with obesity.

According to Acta Medica Iranica, the 100mg of pine bark extract in each serving of Umzu Redwood could improve the body composition of obese individuals. A two-month study of 38 obese women demonstrated body composition improvement after using pine bark extract. That includes markers for central obesity as well as several metabolic syndrome indicators in participants.
