Learn about each item below.

All about Flush
Flush's ingredients work quickly to gently flush the urinary tract. Special ingredients alkalize the urine, making it less acidic, unlocking the power of d-mannose. At the same time, Flush delivers immune support.
-
D-Mannose
Binds to microorganisms in the urine
D-Mannose is a type of carbohydrate that occurs naturally in small quantities in many fruits and vegetables including apples, peaches, green beans, and broccoli. D-Mannose is an important part of human metabolism and urinary health. It has been shown to bind to microorganisms and flushes them from the urinary tract.
-
Potassium Citrate
Alkalizes the urine, unlocking the power of D-Mannose
Citrate is the salt form of citric acid. In Voolast Flush, we have potassium citrate. When mixed in water, potassium citrate dissolves into potassium and citrate ions. Potassium citrate has an alkalizing effect on the urine, meaning it makes the urine less acidic. Potassium ions are required for proper hydration and replace the potassium lost during urination.
-
Citric Acid
Alkalizes the urine in a similar way to Potassium Citrate
Citric acid is a weak acid commonly found in many fruits. Despite being an acid, it has an alkalizing effect on the urine, meaning it makes the urine less acidic. Citric acid, along with the natural lemon flavor, gives Voolast Flush its sour citrus taste.
-
Vitamin C (non-acidic)
Immune system function
The form of Vitamin C found in Voolast Flush is called ascorbate. Ascorbate is the non-acidic salt of ascorbic acid. Vitamin C is also an essential nutrient, and is required for many processes in the body, including immune system function. It is an antioxidant, which provides protective benefits in the human body and is excreted in the urine. Vitamin C has been studied for its positive effects on the immune
system. -
Vitamin B6
Foundational to whole body health
Vitamin B6 refers to a group of compounds that enable proper protein, carbohydrate, and fat metabolism. The form of Vitamin B in Voolast Flush is called pyridoxine hydrochloride. Pyridoxine is found in many common plant foods like pistachios and cacao. Vitamin B6 is an essential nutrient, meaning that people need to obtain it from the diet to live. Vitamin B6 is water-soluble and excreted in the urine. Its involvement with many interactions in the body, make it foundational to whole body health.
-
Magnesium
Essential nutrient lost during urination
Magnesium is another essential nutrient lost during urination. It is required for hundreds of functions in the body, including the creation of DNA. The magnesium in Voolast Flush is in the form of magnesium ascorbate (the magnesium salt of Vitamin C) and magnesium carbonate (the salt of magnesium and carbonate, which is used to carbonate water).
-
Calcium
Acts as an electrolyte, aiding in hydration
Calcium is an ion that acts as an electrolyte. Calcium comes from our diet, and is required for a range of things, including bone production and strengthening, proper nerve function, and muscle function. In Voolast Flush, calcium is included in a salt form with ascorbate, called calcium ascorbate. When in fluid, these salts dissolve into calcium and ascorbate ions. Calcium intake needs to keep up with or exceed calcium loss in the urine in order to maintain proper bone mineralization and hydration.

Other ingredients
Provides Flush's color, taste, and texture.
Beet root - This extract from beet roots gives Voolast Flush its bright pink color and added flavor. *Pink Lemonade Only
Natural lemon flavor - Made from dehydrating real citrus, our natural lemon flavor gives Voolast Flush its lemonade taste. *Pink Lemonade Only
-
Other ingredients
Provides Flush's color, taste, and texture.
Rebaudioside A (from stevia leaf extract) - Stevia is a natural, zero-calorie sweetener from the stevia rebaudiana plant, which is native to South America. Rebaudioside A is purified from the leaf and is responsible for the sweet taste. It is purified to remove things like oxalates and other compounds.

All about Defend
Defend cleanses biofilm and supports bladder wall integrity. Biofilm is a collection of microorganisms bound together that attach to surfaces, like the bladder wall. Mechanism research on the ingredients in Defend shows their ability to cleanse biofilm.
-
Turmeric Root Extract
Cleanses biofilm
Turmeric Root Extract (95% Curcuminoids) is the “active” compound in turmeric, a flowering plant commonly used as a spice that is a member of the ginger family. Turmeric Root Extract gives Voolast Defend its yellowish color. Biofilm can build-up in the urinary tract and turmeric root extract (along with the polyphenols from green tea) has been shown to cleanse biofilm in preliminary laboratory research. The curcumin in Voolast Defend is extracted from the turmeric root.
We recommend talking with your physician if you’re pregnant, nursing, take blood thinners or have a history of liver or gallbladder issues. If you take blood thinners, curcumin, an ingredient in Defend, may cause additional blood thinning. Stop use and see your physician if you develop symptoms of liver problems, such as fatigue, jaundice, and dark urine.
-
Green Tea Leaf Extract
Contains EGCG & EGC, catechins that cleanse biofilm
This extract is mostly (95%) made up of micronutrients in green tea leaves called catechins, like EGCG and EGC. These have been the subject of much research on various health benefits and have antioxidant properties. Along with curcumin, catechins have been shown to cleanse biofilm in preliminary laboratory research. The green tea extract in Voolast Defend is from the leaves of green tea plants.
-
D-Mannose
Binds to microorganisms in the urine
D-Mannose is a type of carbohydrate that occurs naturally in small quantities in many fruits and vegetables including apples, peaches, green beans, and broccoli. D-Mannose is an important part of human metabolism and urinary health. It has been shown to bind to microorganisms and flushes them from the urinary tract.
-
Vitamin D3
Supports bladder wall integrity
42% of all adults in the U.S. are Vitamin D deficient. The vitamin D in Defend is vitamin D3, also called cholecalciferol, the form of vitamin D made by the skin when exposed to sunlight. New research shows that Vitamin D supplementation increases tight junction proteins in the bladder. Essentially, these proteins connect cells that are next to each other.
-
Black Pepper Powder
Increases the bioavailability of curcumin by 2,000%
Piperine is the “active” compound in black pepper. Oddly enough, Piperine can increase the bioavailability of curcumin by 2,000%! Typically, curcumin has poor bioavailability, meaning our bodies don’t absorb the ingredient well on its own. Voolast Defend includes black pepper powder in a small dose to enable our bodies to better absorb curcumin.
-
Other ingredients
Provides Defend's capsule and consistency
Hypromellose – This is a vegetarian polymer used to make the capsule.
Rice Flour – This is used to keep the space packed tightly to secure the ingredients.
Magnesium Stearate – This is a common ingredient in food and supplements to safely keep powders from clumping.
Silica – Also known as silicon dioxide, silica is one of the most common compounds on earth and is found in many plants. Commonly used in food products, in Voolast Defend, silica safely maintains the powder’s texture and keeps it from clumping together.

All about Promote
Promote is a vaginal probiotic blend with clinically studied ingredients to balance your vaginal microbiome. This is key since vaginal health and urinary health are connected.
-
Lactobacillus Acidophilus & Lacticaseibacillus Rhamnosus
The "good" bacterial strains that helps maintain healthy vaginal bacteria.
Lactobacillus Acidophilus and Lacticaseibacillus Rhamnosus are 2 specific types of “good” bacteria that support vaginal health. When consumed orally, these bacteria travel from the gut to the vagina, where they can populate. Promote helps maintain this healthy vaginal bacteria, which is a key component of urinary tract health.
-
Lactoferrin
A protein that supports a healthy vaginal microbiome.
Lactoferrin is a protein that works together with good lactic acid bacteria to support a healthy vaginal microbiome. By promoting a balanced vaginal environment, lactoferrin aids lactic acid bacteria in reducing itching and discharge, providing month-long comfort for your vaginal health. †
Can I use Promote if I am lactose intolerant?
One ingredient in Promote, Lactoferrin, is derived from milk. Reactions to different milk-derived ingredients may vary based on a person's sensitivity to lactose. Promote has never been specifically studied in those with lactose intolerance. Therefore, we recommend that individuals with lactose intolerance concerns speak to their healthcare practitioner before taking Promote.Have a question?
