In this brief video, Brigid Titgemeier explains that many people mistakenly assume that eating a nutrient‑rich, “healthy” diet guarantees full nutrient absorption. She argues that persistent nutrient deficiencies, even among those who consume wholesome foods, are usually caused by poor digestion, leaky gut, and chronic stress, which impair the body’s ability to absorb nutrients. Consequently, she advocates a holistic, upstream approach that addresses gut health and stress management rather than relying solely on supplementation from practitioners.

When it comes to nutrient deficiencies, most people think because they're eating a nutrient-rich diet that that means that they're absorbing all of those nutrients. When you have a high need for support for a number of different nutrients, which we see all the time, even in people that are eating quote unquote healthy, it's either a result of poor digestion or low nutrient absorption. It's rarely a consumption issue. It's usually that people are eating good sources of these foods that would theoretically increase their nutrient levels, but they are having digestive issues, leaky gut, high levels of stress that are impacting their underlying nutrient absorption. So it's not just about working with a practitioner that will give you supplements for those nutrient deficiencies. It's about taking a holistic approach to understanding how you can work upstream to support your body in absorbing those nutrients.
