Here is a video from Robert Yang, nutritionist from Titleist Performance Institute. I have seen Robert speak a few times a TPI certifications and Summits. He is always one of the most knowledgeable and informative speakers.
Golf takes a long time, you are out there for a while and it's really important to make sure you are maintaining energy levels. Many golfers think that using sports drinks will help them on the course.
In this video, he explains why you should stay away from typical sports drinks and start using Celtic Sea Salt.
