All about Flush

How it works
- 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’s ingredients take effect upon urination, and deliver immune support.
Directions
- Mix one packet in 8-12 ounces of water. Drink Flush every 3 days and after sex.
What flavor is Flush?
- Flush has 2 flavor options - unflavored and a mild pink lemonade flavor.
How much do I need?
- If you are not having sex: Get 10 packets of Flush and drink every 3 days
- If you are sexually active: Get 20 packets of Flush and drink every 3 days, and immediately after sex.
- If you want maximum support: Get 30 packets of Flush and drink every day.
Flush's science and ingredients

Calcium
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.
Citric Acid
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. *Pink Lemonade Flavor Only
D-Mannose
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.
Magnesium
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).
Potassium Citrate
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.
Vitamin B6
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.
Vitamin C (non-acidic)
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.
Common questions about Flush

Can I drink more than one packet of Flush a day?
Yes, many of our customers drink Flush daily. To be extra safe, we recommend you don’t exceed taking more than 3 individual packets per day.
We do not recommend drinking Flush while on antibiotics because Flush contains potassium and it may be important to limit potassium intake while on some antibiotics. You should begin Flush as soon as you have completed your antibiotics. Keep in mind, Voolast’s products are not a treatment.
Can I drink more than one packet of Flush a day?
Yes, to stay safe, we recommend not exceeding three individual packets per day.
We don’t recommend drinking Flush while taking antibiotics, as it contains potassium, and some antibiotics may require limiting potassium intake. You can begin using Flush as soon as you’ve completed your antibiotics.
Please note that Voolast’s products are not intended as a substitution to antibiotics.
Can I take Flush alongside the other products (Promote and Defend)?
Yes, Defend, Flush and Promote, are meant to be taken together. All together, these products make up our Complete Regimen - our most popular product bundle. Taking all three products together provides you maximum urinary support. Flush (our drink mix) flushes the urinary tract, Defend cleanses biofilm from the urinary tract and supports bladder wall integrity, and Promote helps maintain healthy vaginal bacteria. Get the Complete Regimen
How do I know if Flush is right for me?
Flush is one part of our 3-part proactive regimen because it is beneficial for anyone looking for better urinary health. Our signature drink mix is an easy, effective way to flush your urinary tract on a regular basis. Flush can be taken by itself but we do recommend adding Defend if you’re regularly affected by urinary tract health.
How many carbs are in one serving of Voolast Flush?
There are 3 grams of carbohydrate in one serving of Flush.
D-mannose is a key ingredient in Flush and is classified as a carbohydrate. Flush contains 2 grams of D-mannose. However, because the body uses only minimal amounts of D-mannose, it should not interfere with normal, healthy blood sugar regulation.
When should I drink Flush?
Mix one packet of Flush with 8–12 oz of water and drink it after sex, or at least once every three days. Even if you’re not sexually active, Flush is beneficial for regularly flushing the urinary tract.
Flush can be taken at any time of day. If you’re also using Voolast’s other proactive urinary tract health supplements (Defend and/or Promote), it’s safe to take them together—just swallow each separately.
Why Defend?
Defend is one part of our 3-part proactive regimen, recommended for anyone impacted by urinary health 3 times or more a year. Defend cleanses biofilm, which helps to keep the urinary tract clear on a day-to-day basis. It also supports bladder wall integrity. You can take Defend by itself, but we recommend everyone looking for better urinary health also take Flush (our drink mix).
All about Defend

How it works
- Mechanism research on the ingredients in Defend shows their ability to cleanse biofilm. Defend also supports bladder wall integrity. With these two functions, Defend helps to keep your bladder clean in the face of hard-to-pinpoint things like stress, hormonal changes and holding your bladder.
Directions
- Each bottle includes a 1-month supply (60 capsules). Take 2 capsules together with water daily.
What is biofilm?
- Biofilm is a collection of microorganisms bound together that attaches to surfaces, like the bladder wall. Mechanism research on the ingredients in Defend shows their ability to clean biofilm.
Defend's science and ingredients

Black Pepper Powder
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.
D-Mannose
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.
Green Tea Leaf Extract
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.
Turmeric Root Extract
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.
Vitamin D3
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.
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.
Common questions about Defend

Can I take Defend alongside the other products (Flush and Promote)
Yes, Defend, Flush and Promote, are meant to be taken together. All together, these products make up our Complete Regimen - our most popular product bundle. Taking all three products together provides you maximum urinary support. Flush (our drink mix) flushes the urinary tract, Defend cleanses biofilm from the urinary tract and supports bladder wall integrity, and Promote helps maintain healthy vaginal bacteria.

Does Voolast have caffeine in it?
Green tea leaf extract is an ingredient in Defend, but the caffeine is removed during the extraction process, leaving only a small amount. This small amount is unlikely to have a stimulating effect, but individuals who are highly sensitive to caffeine may prefer to take Defend earlier in the day.
How do I know if Defend is right for me?
Defend is one part of our 3-part proactive regimen. It’s designed to keep the urinary tract clear on a day-to-day basis by regularly cleansing biofilm, and it also supports bladder wall integrity. You can take Defend by itself, but we recommend that everyone looking for better urinary health also take Flush (our drink mix).
How is Defend different from Flush?
Defend and Flush contain different active ingredients. While the two products are complementary, they don’t have the same function. Defend is designed to keep the urinary tract clear on a day-to-day basis by regularly cleansing biofilm, and supporting bladder wall integrity. Flush (our drink mix) flushes the urinary tract when you need support, like after sex, with the right amount of effective ingredients. For more support, we recommend bundling the two
Is it vegan?
Voolast Defend is not vegan because the vitamin D is sourced from sheep's wool. We chose this source because it is the same version used in clinical research, and we wanted to ensure the maximum efficacy. We apologize for how this may affect our vegan customers.
What if I'm already taking Vitamin D?
The recommended daily upper limit for vitamin D is 4000 IU. Most vitamin D supplements have <2000 IU, and Voolast Defend now includes 1500 IU. So, most people should be in the clear, but if you are currently taking other vitamin D sources be sure to check the volume. We've included that amount to be close to the clinical research amounts but not have a full 2000 IU in case people are supplementing with vitamin D that goes up to 2000 IU to stay at a lower dosage of 3,500 per day.
What is biofilm?
Biofilm is a collection of microorganisms bound together that attaches to surfaces, like the bladder wall. Mechanism research on the ingredients in Defend shows their ability to clean biofilm.
Why are Voolast Defend capsules orange?
The orange color you're seeing is curcumin powder, one of the ingredients in Defend. Due to the natural properties of curcumin, slight color variations can occur from month to month — this is completely normal!
Why Promote?
Promote is one part of our 3-part proactive regimen, recommended for anyone including those who are sexually active, perimenopausal, and/or postmenopausal. Since vaginal health is tightly linked to urinary tract health, maintaining a balanced vaginal microbiome is crucial.
Our specialized vaginal probiotic, with clinically studied ingredients, helps maintain healthy vaginal bacteria and yeast levels. Plus, just 1 capsule per day for 15 days reduces itching and discharge for the entire month. †
You can take Promote by itself, but if you’re here for proactive urinary solutions, you should also take Flush—which is crucial for our maximum support.
All about Promote

Promote's science and ingredients

Lactobacillus Acidophilus & Lacticaseibacillus Rhamnosus
Lactobacillus Acidophilus & 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
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. †
Other ingredients
Provides Promote’s capsule and consistency
Hypromellose – This is a vegan polymer used to make the capsule.
Magnesium Stearate – This is a common ingredient in food and supplements to safely keep powders from clumping.
Microcrystalline cellulose - Microcrystalline cellulose is purified plant polymer. Cellulose composes most of the dry weight of most plants. Used as a bulking agent to keep the capsules tightly packed without extra air.
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 Promote, silica safely maintains the powder’s texture and keeps it from clumping together.
Common questions about Promote

Can I take Promote alongside the other products (Flush and Defend)?
Yes, Defend, Flush and Promote, are meant to be taken together. All together, these products make up our Complete Regimen - our most popular product bundle. Taking all three products together provides you with our maximum support. Flush’s (our drink mix) D-mannose works to flush the urinary tract. Flush also delivers immune support. Ingredients in Defend cleanse biofilm according to mechanism research and includes vitamin D to help support bladder wall integrity. Promote’s ingredients supply “good” lactic acid bacteria plus lactoferrin that support vaginal health. This is key since vaginal health and urinary health are connected. Get the Complete Regimen.
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.
Does Promote help with digestion?
No. Promote is a probiotic designed for vaginal health, not digestive health. Not all probiotics are the same, and there are many different types of lactobacillus, and they live in different parts of the body. The types of lactobacillus in Promote are specific to the vagina
What is lactoferrin?
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.
Why aren't there more strains in Promote?
We’ve included the strains shown to maintain vaginal health and have decided to not include anything extra. Why? Microbiomes are sensitive ecosystems, and we believe it is better to not include strains with unknown impact.

From our founder: I had 8 UTIs in one year…
“I was stuck in the cycle of UTIs for years. I was desperate for a way to get ahead, but was told there was little I could do. This inspired my husband and I to start Voolast, alongside doctors & scientists. Now, we’ve been able to help over 500,000 people and counting. Ready to give us a try?”
