A Functional Supplement for Kidney Health During OCT and PCT Cycles

This article explores a powerful supplement for kidney health, especially during steroid and post-cycle therapy (PCT) cycles.

 

Cranberry: The Kidney's Best Friend Cranberry is a fruit packed with flavonoids, with its most abundant compounds being proanthocyanidins and anthocyanins. This isn't surprising, given its vibrant red color and tart taste. 

 

A small warning: Due to its high soluble fiber content, excessive consumption may lead to diarrhea.

How It Works: The Magic of Proanthocyanidins One of the most valuable properties of proanthocyanidins is their ability to reduce lipid oxidation and protein glycosylation. This is a big deal because it reduces oxidative stress in the mitochondria, which is incredibly important for individuals with diabetes and those on steroid cycles. 

This valuable isoflavone can also bind to microbes on the walls of the urinary tract, helping to flush out harmful agents. The power of cranberry extract in this regard is so strong that it can provide a better response than the antibiotic fosfomycin in treating urinary tract and bladder infections! 

 

A Supercharged Combination!  You can get an even better response by combining it with D-mannose sugar. While cranberry supplements have many more benefits, there's one key feature particularly relevant for steroid cycles:

This supplement can lower the pH of urine, converting quinic acid into hippuric acid. This mechanism prevents bacteria from binding to a receptor on the mucosal membrane of the upper and lower urinary tracts, which helps reduce kidney toxicity. This effect is so significant that it can be useful in cases of chronic kidney failure and may help decrease blood creatinine and urea levels. This makes it a great option to consider alongside steroids that carry a risk of kidney toxicity. 

 

Final Note: Some sources suggest that cranberry extract consumption might increase oxalate accumulation, raising the risk of kidney stones. However, other sources refute this claim. As with any supplement, it's always wise to consult a healthcare professional.

Best time to consume: Right before bed!
