The ability to direct clients to consume more healthy foods.
I learned a lot more about Vitamin D and how it is converted in the body. I will start ensuring my clients are being tested for Vitamin D levels is necessary and recommending D3 & K2.
More insight into Vitamin D. I will apply the content when counseling clients on nutritional needs and helping to formulate meal plans.
I learned additional biological key points about the synthesis of Vit. D in the body. Also, I learned about old and current research data on the multiple possible benefits of Vit. D. I have a better understanding of the pro and cons of the daily recommended intake as I know that many athletes take too much and recreational people take too little. For a Professional Trainer Instructor, the course was very well constructed and relevant to our needs in discussing the benefits of Vit D with our students.
An understatement of Vit D and it’s role in the body and the Supporting players needed for maximum benefit. To be able to speak/counsel a bit when the topic comes up
