Three different things sharing a shelf. Bee pollen is the pellet a forager carries on her legs, about 20 to 30% protein with a flavonoid load like good fruit ¹. Propolis is the resin bees use to caulk the hive; its polyphenol content swings by ten times between products carrying the same word ². Royal jelly is the secretion nurse bees feed the queen, marked by 10-HDA, a fatty acid nearly absent from a diluted product ³.

Propolis is the only one that clears the bar. In type-2 diabetes, eight to twelve weeks at 900 to 1500 mg a day drops fasting glucose by about 13.5 mg/dL and HbA1c by half a point ⁴. That is roughly half of what metformin does, small but real for a borderline number.

Royal jelly shifts LDL about 8% down in a four-week, fifteen-person trial ⁵. Bee pollen is thinnest of all: antioxidant markers move in the lab, and no large healthy-adult trial of any marketed claim exists ¹.

The immune claim is where the evidence collapses. No randomised trial shows that eating bee products cuts the colds or flus a healthy adult catches in a year. The inflammation biomarkers move a little, sometimes not at all ³. "Supports immunity" is the label, not the data.

This is a buy-or-skip call, and mostly a skip.

What the money does elsewhere. The cabinet runs $100 to 200 a year, a thousand-plus over a decade. Pointed at things with real effect sizes, that is a gym membership held past March, the dental cleaning you keep rescheduling, or a statin conversation with your GP that costs nothing and moves the needle far harder than any jar on the bee shelf.
