I ordered these to take on a golf trip to the desert as i get drained when in a dry climate. when did rice flour keto become keto friendly?

It’s trace amounts so you just gotta do your own benefit/risk analysis :)

Where is this sourced from? And where is it produced?

A simple reading of the product description would have answered your question. It clearly states that the product is a "blend of hydrolyzed grass-fed beef, wild marine, chicken and eggshell membrane collagen, providing types I, II, III, V and X. We also include a healthy dose of biotin". It further states that the product is "sourced and manufactured in the USA at an FDA registered, NSF & GMP certified facility."

How many grams of protein per serving

1 scoop = 1 serving= 7grams of protein

Will this product help with extreme hair loss?

Highly unlikely. It will simply supply the integumentary system with needed nutrition. There are various causes for hair loss, none of which will be reversed by adding collagen to your diet. The hair that you still have might get stronger/thicker, though.
