How does CranShield 36 work?

Most recurring urinary discomfort starts when E. coli bacteria stick to the bladder wall. Cranberry PACs (type-A proanthocyanidins) and D-mannose each help keep bacteria from latching on, in two different ways, and the big glass of water you drink with every stick helps flush them out. Together, they support a healthy urinary tract every day.*

Why 36 mg of PACs?

In cranberry research, the benefit shows up at 36 mg of PACs per day or more. Below that, studies don't see a meaningful difference. Many cranberry pills and juices don't say how many PACs they contain. We measure ours with the DMAC method and print it on the box.

How do I take it?

Once a day, stir one stick into a big glass of water (16 oz) and drink it. Many women take it in the evening or after sex. Keep drinking water through the day.

Can I take it during an active infection instead of antibiotics?

No. CranShield 36 is a daily support supplement, not a treatment. If you have symptoms right now, especially fever, chills, back or side pain, or blood in your urine, contact your healthcare provider. You can use CranShield 36 alongside the care your doctor recommends.

How quickly will I notice a difference?

This is a daily habit, not a quick fix. In cranberry studies, women took it every day for 6 to 12 months. Give it at least 2 to 3 months of daily use. That's why every order comes with our 60-day money-back guarantee.

The dose that counts. Nothing you don't need.

Why it keeps coming back

It's not your hygiene. It's bacteria that stick.

Most recurring urinary trouble starts the same way: E. coli bacteria latch onto the bladder wall and won't let go.

How CranShield 36 helps keep bacteria from sticking to the bladder wall

Peeing after sex, wiping front to back and drinking water all help, but they can't stop bacteria from gripping the lining of your bladder. CranShield 36 works on that grip, every day. Cranberry PACs and D-mannose each help keep bacteria from sticking, in two different ways, and the big glass of water you drink with every stick helps flush them out.*

1. Anti-stick, two ways

Type-A cranberry PACs and D-mannose each help block a different way bacteria hold on to the bladder wall.*

36 mg PACs2 g D-mannose

2. A daily flush

Every stick goes into a big 16 oz glass of water, so drinking more becomes part of the routine.*

16 oz waterOnce a day

Sugar-free. No hibiscus. No high-dose vitamin C.

What's inside

Two studied ingredients. Doses on the label.

No mystery blends, no 'biofilm' buzzwords. Just the amounts research uses.

CranShield 36 ingredients: cranberry extract 36 mg PACs, D-mannose 2 g, water, natural berry flavor
Main active

Cranberry extract, 36 mg PACs

Standardized to 36 mg of type-A proanthocyanidins (PACs), measured by the DMAC method. Helps keep bacteria from sticking to the urinary tract wall.*

In a 2023 Cochrane review of 50 trials, cranberry products were linked to about 30% fewer symptomatic UTIs. A 2024 meta-analysis found the effect at 36 mg of PACs per day or more, not below.

Support

D-mannose, 2 g

A simple sugar that passes into urine and helps maintain a healthy urinary tract.*

In a 2020 double-blind trial, women taking D-mannose with cranberry PACs had fewer E. coli UTIs than with PACs alone. On its own, D-mannose has shown mixed results, which is why we pair it with PACs.

The ritual

A big glass of water

Each stick is made to be stirred into 16 oz of water, once a day.

In a 2018 trial, women who drank an extra 1.5 L of water a day had about half as many bladder infections over 12 months.

Sugar-free

Natural berry flavor + stevia

A light, refreshing taste with zero sugar. No hibiscus, no high-dose vitamin C.

Study results refer to individual ingredients, not to the CranShield 36 formula.

Why nothing has worked so far

Most cranberry products don't tell you the dose. We print it.

If you've tried juice, cranberry pills and plain D-mannose and you're still stuck in the cycle, here's why.

Frequently Asked Questions

How long does one box last?

One box of 30 stick packs lasts 30 days at one stick a day.

What does it taste like?

A light, natural berry taste, sweetened with stevia, with zero sugar. It's not sour like cranberry juice.

How is it different from Uqora or plain D-mannose?

D-mannose alone has shown mixed results in studies. CranShield 36 pairs 2 g of D-mannose with cranberry extract standardized to 36 mg of PACs, the daily amount used in cranberry research, and prints that dose on the box.

Who should not take it?

If you take warfarin or another blood thinner, have diabetes, kidney disease, kidney stones or interstitial cystitis, or are pregnant or nursing, ask your healthcare provider before use. D-mannose can loosen stools in some people.

Can I take it with my other medications?

CranShield 36 contains no antibiotic. If you take prescription medication, especially a blood thinner, check with your pharmacist or healthcare provider.
