Cranberry Juice Powder
Vaccinium macrocarpon
A concentrated source of proanthocyanidins (PACs) and antioxidant polyphenols from the American cranberry — best known for urinary tract health but also valuable for cardiovascular protection, gut health, and reducing oxidative stress.
What Is It?
Cranberry Juice Powder is made by spray-drying or freeze-drying concentrated cranberry juice, preserving its active polyphenol content in a stable, concentrated form. American cranberries (Vaccinium macrocarpon) are native to North America and one of the richest sources of a unique class of antioxidants called A-type proanthocyanidins (PACs) — not found in most other fruits.
Beyond their well-known role in urinary health, cranberry polyphenols have demonstrated meaningful cardiovascular benefits, antioxidant activity, and gut microbiome support in emerging research.

How It Works
Cranberry's health benefits come primarily from its unique A-type proanthocyanidins and other polyphenols:
- Urinary health — A-type PACs have a unique anti-adhesion effect, preventing E. coli bacteria from attaching to the walls of the urinary tract — reducing UTI frequency
- Cardiovascular — cranberry polyphenols improve HDL function, reduce LDL oxidation, improve endothelial function, and reduce arterial stiffness
- Antioxidant — cranberries rank among the highest antioxidant capacity of commonly consumed fruits
- Gut microbiome — emerging research shows cranberry polyphenols selectively promote beneficial gut bacteria while inhibiting harmful strains
- Anti-inflammatory — inhibits multiple inflammatory pathways including NF-κB

Side Effects & Considerations
Cranberry is a food-derived supplement with an excellent safety record:
- Very well tolerated by most people
- High doses may cause digestive upset or diarrhea in sensitive individuals
- Naturally high in oxalates — those with calcium oxalate kidney stones should moderate intake
- May enhance the effects of warfarin (blood thinner) — consult your doctor
- Acidic nature may aggravate acid reflux in some individuals
- Cranberry juice (not powder) is high in sugar — powder form avoids this concern
- Safe for most populations including during pregnancy at food-equivalent doses

Typical Dosage Range
500mg – 1,500mg daily (standardized extract)
Effective doses vary by standardization. Look for products standardized to PAC content — 36mg of PACs per day is the amount shown effective for urinary tract health in clinical research. Whole cranberry powder doses of 500-1,500mg provide meaningful antioxidant and cardiovascular benefits. Can be taken with or without food at any time of day.
