Alternatives to Azo Active Ingredient Products

Urinary tract infections (UTIs) are common among women, and sometimes men, too. Some of the most common symptoms include persistent pain, burning sensation, and frequent urge to urinate, and blood in urine. While the azo active ingredient is widely popular in treating UTIs, some people may experience side effects like dizziness, nausea, headache, and upset stomach. If you prefer to avoid these side effects or if azo-based products are not working well for you, you may explore the following alternatives:

1. D-Mannose

A naturally occurring sugar molecule, D-mannose has been known to effectively combat UTIs by stopping bacteria from sticking to your urinary tract. D-mannose is a type of sugar that does not get absorbed by the body, which means it can pass through the kidneys and eventually the urinary tract. This prevents bacteria from sticking to the bladder walls, allowing you to flush them out of your system. You can purchase D-mannose supplements in health stores or online. However, before taking any supplements, it’s important to talk to your healthcare provider first.

2. Probiotics

Probiotics are microorganisms that can offer several health benefits. They are bacteria that are similar to the ones that naturally occur in your body. These beneficial bacteria help to promote a healthy urinary tract, making it difficult for harmful bacteria to multiply. Also, some strains of probiotics actively produce hydrogen peroxide, which helps to control the growth of bacteria and restore balance to your urinary tract. You can take probiotics in supplement form or eat foods that are naturally high in probiotics, such as yogurt, kefir, and fermented vegetables.

3. Cranberry Supplements

Cranberry is often used as a natural remedy for UTIs. The fruit is high in compounds known as proanthocyanidins, which prevent bacteria from adhering to the urinary tract lining. Cranberry supplements are available in various forms, including juice, capsules, and tablets. Research suggests that taking cranberry extracts can help prevent UTIs among women who have a history of recurring infections. However, it’s important to note that cranberry supplements should not replace antibiotics used to treat active infections.

4. Drink Plenty of Water

Drinking plenty of water is crucial for maintaining a healthy urinary tract. Water helps to flush out bacteria and toxins that may cause UTIs. It’s important to drink enough water every day and to keep your urine light in color. If you’re sweating a lot or if you’ve been urinating frequently, try to increase your water intake accordingly.

5. Avoid Irritants

Certain irritants can increase your chances of developing UTIs. Some of the most common irritants include:

• Bubble Baths
• Feminine Sprays
• Spermicidal Jelly
• Douches
• Tight Clothing

Bubble baths and feminine sprays can irritate your urinary tract and increase the risk of developing an infection. Also, spermicidal jelly and douches can alter the pH balance of your vagina, which could cause an overgrowth of bacteria and increase the risk of developing a UTI. Tight clothing like jeans, leggings, and tights can add pressure to the urinary tract leading to UTIs. Wear loose-fitting clothing and cotton underwear to prevent UTIs.

In conclusion, there are many effective alternatives to azo active ingredient products that can help prevent UTIs and relieve symptoms. D-mannose, probiotics, cranberry supplements, drinking plenty of water, and avoiding irritants can all play a role in maintaining a healthy urinary tract. However, if you continue to experience symptoms, it’s important to contact your healthcare provider right away to avoid any complications.
