I've started doing keto (more specifically a power keto where you put it in water).. anyways can my powder keto pass security and a bigish plastic bottle (with a metal ball to help shake it up)?
The answer may depend on which airport(s) you’re travelling through and/or the size of the containers. The TSA website says:
Powder-like substances greater than 12 oz. / 350 mL must be placed in a separate bin for X-ray screening. They may require additional screening and containers may need to be opened. For your convenience, we encourage you to place non-essential powders greater than 12 oz. in checked bags.
