Random conversation at a gym in LA changed how I think about ecom niches. Guy next to me between sets mentioned he sells a prostate supplement. Doing $2.1M/month. I almost laughed. Prostate supplements. Not exactly the sexiest product. Then he showed me his margins. 41% net. Over $860K/month in actual profit from one product that nobody in his social circle knows about. He said: "Everyone wants to sell the cool product. Pre-workout. Collagen. Greens powder. Those categories have 500 brands fighting over the same 25-year-old gym bro. Prostate health? My customer is a 55-year-old man with money who doesn't price shop. He sees an ad that speaks to his exact problem, he buys, and he reorders every 3 months like clockwork." His US subscription retention rate: 71% at 6 months. Average customer lifetime value: $430. He's now expanding into Germany and Japan — two countries with rapidly aging populations and almost zero competition in the prostate supplement space on Meta. But with a different model for Europe. No subscriptions. High-AOV bundles (3-month and 6-month supply packs), post-purchase upsells, and email reorder flows timed to when the product runs out. He said the European margin model is different but the profit per customer ends up similar because the upfront AOV is so much higher when you force bundles instead of single units with a subscription checkbox. He found both markets by scanning competitor activity on GetHookd — searched prostate supplements in Germany and Japan and saw almost zero brands running. That empty search result was all the validation he needed. The lesson: the "boring" health niches that nobody wants to talk about on Twitter — prostate, menopause, blood pressure, joint pain, vision — are where the real money is. High AOVs, loyal customers, zero competition from the influencer brands. Stop chasing the trendy supplement categories. The unsexy niches print harder and longer.
