Understanding the Complexities of Nutrition Supplements and MLMs

Chapter 1: The Disillusionment with Direct Sales in Nutrition
My personal journey in the world of nutrition has led me to a disappointing realization about the direct sales and multilevel marketing (MLM) models prevalent in the nutrition supplement sector. This approach often turns wellness into a rather “toxic” phenomenon.
When people inquire about my academic background, I often mention my studies in “Nutrition.” Their responses frequently highlight the immense financial potential of this “multimillion-dollar industry,” likely pointing to the businesses engaged in selling nutritional supplements. However, as a nutrition scientist, I’ve found that we do not earn substantial incomes, and ethical dilemmas abound in this field, particularly regarding the direct sales and MLM practices seen in companies like Amway (Nutrilite), Herbalife, and USANA. While a handful of their products may be beneficial, many make exaggerated claims unsupported by scientific evidence.
Recently, an old acquaintance reconnected, now involved in this business model. My experiences with various individuals in this field have shaped my perspective, especially following my rigorous training during my PhD in clinical nutrition. Here, I voice my discontent with some prevalent assertions about nutritional supplements:
The Universality of Supplement Needs
The primary aim of such businesses is to sell products, often irrespective of whether individuals genuinely require them. While some may have specific deficiencies due to allergies or intolerances, nutrient shortages are surprisingly uncommon among those who can afford such supplements. I prefer consuming delicious, whole foods rich in natural vitamins and minerals instead. If health is a priority, focus on nutrient-dense foods such as tofu, soy, eggs, dairy, nuts, and vibrant fruits and vegetables. Remember, moderate consumption of meat is also valuable. Most importantly, maintaining a healthy weight is crucial for overall well-being.
Claims of Nutrient-Depleted Soil
It is often claimed that “The soil is now lacking micronutrients, you cannot get enough nutrients just by eating foods.” This fear-mongering tactic is frequently utilized to promote multivitamin and multimineral supplements. While it is true that about 2 billion individuals globally face micronutrient deficiencies, it doesn’t imply that all supplement users are deficient. The body’s ability to absorb nutrients is highly regulated by the gut. If certain minerals are lacking, the gut typically enhances absorption and reduces excretion. Nutritional studies that only evaluate dietary intake through records or recall may overestimate deficiency levels unless blood samples are analyzed. If nutrient status is a concern, it’s advisable to consult a physician for blood tests before purchasing supplements.
Research-Backed Claims
“Oh really?” When purchasing products, we naturally seek assurance that they deliver on their promises. The first question to consider is whether the supplement has undergone testing in humans or animals. Many supplements may show efficacy in animal studies but fail to translate to human applications, regardless of marketing hype. It is essential to ascertain whether the supplement has been tested on healthy individuals, those with early or late-stage diseases, young or elderly populations, and at what dosages.
Probiotics, in particular, can be problematic. As highlighted by Sam Westreich, PhD, commercial probiotics often contain ingredients that may not be beneficial, raising concerns about their effectiveness.

The Myth of Cure-All Supplements
A single supplement cannot resolve every health issue. If a product claims to prevent diabetes, weight gain, or promote cell regeneration, it’s likely misleading. Salespeople often target a broad audience with the same product, which is ethically questionable. Health professionals recognize that different patients with similar symptoms often require individualized assessments. Ethical practitioners prioritize your health by objectively evaluating your condition before suggesting any products.
Concluding Remarks
It’s crucial to understand what you are purchasing. The marketing strategies that imply everyone needs supplements are somewhat unethical, as only a small percentage of individuals truly require them. If presented with a case study of miraculous recovery linked to a supplement, it’s essential to recognize that other treatments may have played a role in the outcome.
As a nutrition scientist engaged in research on human nutrition, I advocate for informed decision-making regarding supplements. Nutrition products are not as strictly regulated as pharmaceuticals, allowing companies to market items without rigorous clinical trial validation. Most importantly, supplements should not serve as substitutes for a balanced diet, healthy lifestyle choices, or traditional medical treatments.
