Lean Casein

Genetix Nutrition Lean Casein is a casein that SuppSaver tracks. 1 Australian retailer carries this product. The best price we're currently tracking is $79.95 at Nutrition Warehouse, which works out to $11.74/100g protein — the true-cost figure we rank every casein protein supplement on. That comes to roughly $3.63 per serve. At 77% protein by weight, the cost per 100g of actual protein — not just powder — is what decides whether it's good value.

Retailer prices shift week to week, so we re-check every listing nightly and rank by true cost per 100g of protein rather than sticker price. That lets you see whether Lean Casein is genuinely the cheapest casein protein supplement on the market or simply discounted right now. It's listed in 880g. Shoppers rate it 4.5 out of 5 from 25 reviews. Use the price history, the per-store breakdown and the alternatives below to confirm you're getting the best deal before you buy.
