Unlocking Nature's Secrets: The Science Behind Our Ingredients
Explore Tract Tonic's Ingredients: naturally effective and expertly blended for proactive urinary health.
Urinary Tract Heroes
D-Mannose
Nature's UTI Blocker: D-Mannose is a naturally occurring sugar found in fruits and vegetables like apples, blueberries and broccoli. It plays a crucial role in urinary health by preventing bacteria, such as E. coli, from sticking to the urinary tract walls. By helping to flush out bad bacteria during urination, D-Mannose is a powerful, natural defence against UTIs.
Cranberry
UTI Defence Hero: Cranberries are rich in antioxidants and proanthocyanidins (PACs), known for their anti-adhesion properties that help prevent harmful bacteria from adhering to the urinary tract walls. By disrupting bacterial adhesion, cranberries support your body and urinary tract health in reducing the risk of cystitis flare-ups and recurring UTIs.
Fennel Seed Extract
Natural Diuretic & Anti-Inflammatory: Fennel Seed Extract enhances urinary health by acting as a gentle diuretic, increasing urine flow to flush out toxins. Its anti-inflammatory properties soothe discomfort while its antimicrobial properties protect against cellular damage, making it a natural ally to fight, soothe, protect against urinary tract issues.
Nutritional Powerhouses
Vitamin C (Non-Acidic)
Immunity Booster: The non-acidic form of Vitamin C, known as ascorbate, supports your immune system and acts as a potent antioxidant. It not only helps your body fight off infections but also promotes overall urinary health by maintaining a balanced internal environment.
Magnesium
Inflammation Fighter & Hydration Helper: Magnesium is an essential mineral with anti-inflammatory properties that helps reduce inflammation in the urinary tract and support immune function, which is crucial for fighting off infections. It also maintains electrolyte balance in the body, which is vital for hydration and kidney function and is involved in DNA synthesis to help regulate calcium levels, crucial for muscle and nerve function related to urinary health.
Vitamin B6
Metabolic & Mood Support: Vitamin B6 is essential for processing proteins, fats and carbohydrates, supporting overall body health. Found in foods like pistachios and cacao, this water-soluble nutrient plays a role in nerve function, mood regulation, and immunity, all of which are vital for maintaining a healthy urinary system.
Calcium
Electrolyte & Bone Support: Calcium is an essential electrolyte that supports bone health, nerve transmission, and muscle function. In the context of urinary health, maintaining proper calcium levels helps ensure hydration balance in the body and is necessary to offset the diuretic effects of other ingredients.
Vitamin D3
Bone & Immune Health: Vitamin D3 is essential for calcium absorption and a powerhouse for your health, playing a vital role in urinary, bone and immune function. It helps fortify your immune system to reduce the risk of UTIs and ease conditions like interstitial cystitis with its anti-inflammatory properties. It also strengthens bladder wall integrity by boosting tight junction proteins, crucial for maintaining a healthy urinary system and overall well-being.
pH & Comfort Balancers
Potassium Citrate
Balancing Urinary Acidity: Potassium Citrate is your go-to for maintaining the right pH balance in your urine. By alkalising the urine, it reduces acidity, which eases discomfort associated with cystitis and UTIs. Plus, it replenishes potassium lost during urination, ensuring proper hydration, supporting kidney function and overall urinary health.
Citric Acid
Natural Urine Alkaliser: Despite being an acid, Citric Acid has an alkalising effect on urine, helping to neutralise acidity. This property can ease the burning sensation during urination, making it an essential ingredient for those prone to urinary discomfort.
Other Ingredients
Beetroot Extract
Beetroot extract is used as a natural colouring agent, adding a pink hue to our product. Sourced from beetroots, it provides a beautiful, natural colour without the need for artificial dyes.
Natural Lemon Flavouring
Natural lemon flavouring enhances our products with a refreshing, zesty citrus note. Made from real lemons, it delivers a bright and tangy flavour that perfectly complements our product.
Inulin
Inulin is a prebiotic fiber that supports urinary health by promoting beneficial gut bacteria, which help strengthen immunity and reduce harmful bacteria linked to UTIs. It also aids digestion and bowel regularity, indirectly benefiting the urinary tract.
The unflavoured version excludes beetroot extract, natural lemon flavoring, and stevia, replacing them with inulin.
Stevia
Stevia is a naturally derived, allergen-free sweetener sourced from the Stevia rebaudiana plant. It delivers sweetness without the calories of sugar, making it an excellent choice for those looking to manage their sugar intake. Additionally, stevia is suitable for individuals with glucose allergies or intolerances, offering a safe and natural alternative for sweetening.
