Episode Description from the Publisher

In this episode of The Bodybuilding Dietitians Podcast, we cover the four nutrient deficiencies we see most commonly across our clients and in clinical practice. We discuss vitamin D, iron, magnesium, and omega-3, including how prevalent they are, why they matter specifically for active individuals, how to test for them properly, and what adequate intake actually looks like beyond standard reference ranges. We also cover how to address each through food first and where supplementation makes sense, including which forms and doses are worth using. As always, we wrap up with what we learned this week.   Whether you are a physique athlete, a recreational lifter, or someone looking to optimise their health and performance through nutrition, this episode is for you.   ⸻   Links & Resources Coaching Services – https://www.thebodybuildingdietitians.com/enquirenow  Website – https://www.thebodybuildingdietitians.com/   Instagram The Bodybuilding Dietitians – https://www.instagram.com/thebodybuildingdietitians/?hl=en Team TBD – https://www.instagram.com/_teamtbd_/?hl=en Jack Radford-Smith – https://www.instagram.com/jack.radfordsmith/?hl=en  Damien Cox – https://www.instagram.com/dietitian_damiencox/?hl=en Lauren Stevens – https://www.instagram.com/thephysiquedietitian_/?hl=en   ⸻   Enjoying the podcast?
