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').

• Rugged and durable
• Double-wall insulation to keep your liquids hot or cold for up to 25 hours
• 500ml capacity
• Leak proof screw on lid (BPA-free plastic which is protected from heat by the Stainless Steel bottle which holds your liquids)
• Wide mouth for easy filling of liquids and ice, and easy cleaning
  
• Includes mixing ball to help completely dissolve powder
  
• Add ice, or refrigerate, or freeze before use (optional)
  

*Please take care with hot liquids and we recommend washing by hand.
