Choosing a supplement is also a question of trust. Understanding what has been studied, what was observed, and what those observations mean helps make that choice more informed.
Sanbera’s case study with Dr. Mark D. Emerson explored changes in blood biomarkers in ten healthy adults taking Sanbera supplements daily. The published summary reports findings relating to iron status, cholesterol, and other blood parameters.
Here, we take a closer look at the findings and the context needed to understand them.
Who is Dr. Mark D. Emerson?
Dr. Mark D. Emerson works in nutrition-based lifestyle medicine, with an approach that brings together nutrition, physical activity, sleep, and stress management.
His work places everyday habits at the centre of health, considering how these different aspects of life work together.
What did the Sanbera case study examine?
The case study examined thirteen biomarkers commonly included in routine blood testing in ten healthy adults, including women and men, taking our Daily Essential Women and Daily Essential Men supplements daily.
Blood biomarkers offer a measurable way to explore changes within the body. Interpreting them requires attention to starting values, the size of any change, and each person’s health context.
What were the main findings?
The published Sanbera summary reported the following results:
| Biomarker | Reported finding |
| Ferritin | Increased in 80% of participants |
| Total cholesterol | Lower in 70% of participants |
| Serum iron | Improved in 50% of participants |
| Homocysteine | Reduced in 70% of participants |
These percentages describe how many participants experienced a reported change. They do not describe the size of that change: an increase in ferritin in 80% of participants does not mean ferritin increased by 80%.
Understanding ferritin and serum iron
Iron supports essential functions throughout the body. It is a component of haemoglobin, the protein in red blood cells that carries oxygen from the lungs to the tissues.
Ferritin and serum iron provide different information. Ferritin helps assess stored iron, while serum iron measures iron circulating in the blood.
A rise in ferritin can be relevant when iron stores are low. However, higher ferritin is not automatically a better result: inflammation can also raise ferritin levels. This is why iron status is assessed using several measurements and an individual’s clinical context. [NIH Office of Dietary Supplements: Iron]
For readers considering nutritional support, the useful question is whether their intake meets their needs. Blood test results can help inform that conversation with a healthcare professional.
How should the cholesterol findings be interpreted?
The reported cholesterol changes are a reason to investigate further. On their own, they do not establish that Sanbera lowers cholesterol or reduces cardiovascular risk.
To understand the significance of a result, we would need to know participants’ starting and final values, how long they took the supplements, and how their results compared with a suitable control group.
What can this case study tell us?
A small case study can identify observations that deserve closer investigation. It offers an initial view of what happened within a particular group.
Stronger conclusions require a fuller picture: the study protocol, exact formulations and doses, participant-level results, statistical analysis, and information about other factors that could have influenced the findings.
The Sanbera summary should therefore be read as an account of reported observations. It does not establish that every person taking the supplements will experience the same changes, or that those changes will persist over time.
Bringing the findings into everyday life
When considering a supplement, start with what you need to know: what it contains, the recommended daily intake, and how it fits alongside your diet and any other products you take.
At Sanbera, we make Swiss-made vegan, plant-based supplements for women and men. Our product pages clearly outline each formula’s ingredients and recommended use, helping you decide if they’re right for your daily routine.
Frequently asked questions
Has Sanbera been studied?
Sanbera published a case study with Dr. Mark D. Emerson. It offers preliminary observations; the summary alone does not establish broad clinical efficacy or safety.
Are ferritin and serum iron the same thing?
No. Ferritin helps assess the body’s iron stores, while serum iron measures circulating iron. They are interpreted alongside other results to understand iron status. [NIH: Iron]
Does this study prove that Sanbera lowers cholesterol?
No. This study does not establish a causal effect. A reported change in a small participant group cannot predict an individual result.
Were the current Sanbera formulas used in the study?
The study uses the Daily Essential Women and Daily Essential Men.
