Objectifs de l’étude
Dans cette étude transversale, nous avons examiné les avantages de 20 ans et plus d’utilisation des suppléments Shaklee. Nous avons comparé les usagers de suppléments Shaklee avec ceux qui n’en ont pas pris et ceux qui ont utilisé une seule multivitamine d’autres marques en évaluant le taux de nutriments dans leur sang, ainsi que des biomarqueurs reflétant divers aspects de la santé.
Cette étude a permis de suivre les personnes ayant participé à l’Étude Historique 1 pour déterminer si les bienfaits sur la santé qu’elles avaient ressentis au départ étaient toujours présents 10 ans plus tard. Elle a également permis d’explorer de nouveaux marqueurs de santé pour améliorer notre compréhension des effets de l’utilisation à long terme des suppléments.
Détails de l’étude
Pour comprendre la relation entre la supplémentation et la santé, l’Étude Historique a été menée en collaboration avec des chercheurs de l’Université de Californie à Berkeley.
Gladys Block, PhD., chercheure de renom et professeure d’épidémiologie et de nutrition en santé publique à School of Public Health de l’Université de Californie, Berkeley, a aidé à diriger l’équipe de recherche dans ses efforts.
En utilisant un plan d’étude transversal, les chercheurs ont obtenu des renseignements à partir de questionnaires en ligne, d’examens physiques sur place et de tests sanguins auprès d’un échantillonnage de 278 usagers à long terme de plusieurs suppléments alimentaires fabriqués par Shaklee Corporation. Les données sur les non-usagers et les usagers de suppléments multivitaminés uniques jumelés ont été obtenues à partir de la plus importante et la plus ancienne enquête nationale sur la santé et la nutrition, connue sous le nom d’Enquête nationale sur les examens en matière de santé et de nutrition (NHANES) 2001-2002 et NHANES III 1988-1994.
Les chercheurs ont ensuite comparé les niveaux de nutriments dans le sang, les biomarqueurs de santé et l’état de santé auto-évalué entre les trois groupes. Les résultats ont été ajustés pour tenir compte de quelques variables potentielles comme l’âge, le sexe, la scolarité, le revenu et l’indice de masse corporelle (IMC).
Les suppléments alimentaires consommés quotidiennement par plus de 50 % des usagers multiples comprenaient une multivitamine/minéraux, un complexe B, des vitamines C et E, des caroténoïdes, du calcium avec de la vitamine D, des acides gras oméga 3, des flavonoïdes, du coenzyme Q10 avec du resvératrol, de la glucosamine, un supplément immunologique à base de plantes, un supplément probiotique (femmes) et un supplément protéique de soja (hommes).
Les chercheurs ont examiné les biomarqueurs de santé et l’utilisation des médicaments chez 156 personnes qui avaient pris des suppléments Shaklee pendant plus de 30 ans (soit 10 années supplémentaires d’utilisation de multiples suppléments) comparativement à 806 personnes qui n’avaient pas utilisé de suppléments.
Higher Levels of Key Nutrients in BloodIron, folate, and vitamins A, C, and E levels compared to non-Shaklee multivitamin users and supplement non-users.
Shaklee supplement users had:
Why this matters
There's a common belief that when people take supplements the nutrients aren't absorbed. Since the people who take Shaklee supplements have higher nutrient levels in their bloodstream, this shows that the nutrients were effectively absorbed by their bodies.
Based on NHANES data, many people have sub-optimal levels of most vitamins and minerals. But Shaklee supplement users do not, which means that supplementation is an effective way to fill nutrition gaps.
Better Markers of Heart Health
Shaklee supplement users had:
Why this matters
LDL is often called "bad" cholesterol because it can build up in the walls of arteries, increasing the risk of heart disease and stroke.
HDL is known as "good" cholesterol because it helps remove LDL cholesterol from the blood, reducing the risk of heart disease.
Triglycerides are a type of fat. When you eat, your body converts excess calories into triglycerides for storage. High levels can increase your risk of heart disease.
Better Markers of Cognitive Health and Inflammation Shaklee supplement users had:
Why this matters
Homocysteine is formed when our bodies break down methionine, an amino acid found in food. High levels of homocysteine can be harmful and are associated with heart disease and cognitive decline.
C-reactive protein (CRP) is a protein produced by your liver in response to inflammation. Elevated levels in the bloodstream indicate inflammation or infection in the body.
Healthier Markers of Blood Sugar Control and Weight Management Shaklee supplement users had:
Better Glycemic Control
Healthier Weight
Why this matters
Blood glucose (blood sugar) is the main sugar found in your blood. It comes from the food you eat, and it’s your body's primary source of energy. High levels of glucose in your blood can lead to health issues like diabetes and complications such as cardiovascular disease and nerve damage.
Insulin is a hormone produced in response to the food you eat that helps regulate blood sugar levels. When your body doesn't respond properly to insulin, it has to make even more insulin to keep your blood sugar levels in check.
HbA1c (hemoglobin A1c) is a measure of average blood sugar levels over the past 2–3 months. It is a measure of long-term blood sugar control and is used to monitor diabetes management. Lower HbA1c levels indicate better blood sugar control and reduced risk of diabetes-related issues.
BMI (Body Mass Index) uses height and weight to assess body fat levels and classify individuals as underweight, normal weight, overweight, or obese. A higher BMI generally suggests higher body fat levels.
Very Good to Excellent Health 
of Shaklee supplement users rated their health as “very good” to “excellent”
How does that compare?
56% of non-Shaklee multivitamin users rated their health as “very good” to “excellent.”
49% of supplement non-users rated their health as “very good” to “excellent.”
A Lower Risk of Elevated Blood Pressure and DiabetesShaklee supplement users had:
Why this matters
Lowering the risk of elevated blood pressure and diabetes is important for maintaining good health. It helps reduce the likelihood of developing various chronic health conditions.
Significantly Lower Medication UsageWhy this matters
Low medication use is a meaningful indicator of health and wellness because it shows the effective management of health through lifestyle choices.
