If you care about your health enough to take supplements then you should also care about what shaker you use. Those cheap BPA free plastic shakers still contain other endocrine disrupting chemicals which can seep into your liquids when exposed to high temperatures or stored for an extended period of time.

That's why we opt for Stainless Steel Shakers. The advanced double-wall insulation will keep your liquids refreshingly cool throughout the day, and provides exceptional strength and durability. They're great for mixing protein powder shakes, supplements, smoothies and more (including the odd margarita, just sayin').
