The Overuse of Vitamin D – Why More Isn’t Always Better
Vitamin D has long been seen as a “must-have” nutrient—especially in northern countries like Sweden, where sunlight is limited during much of the year. Known for supporting bone health, immunity, and mood, Vitamin D has found its way into millions of supplement routines. But what if we told you that many people may be taking it unnecessarily? And that overuse can actually do more harm than good? An article from SVT Nyheter features insights from Professor Martin Bergö at Karolinska Institutet, who warns that Vitamin D supplements have no proven benefit for healthy individuals. In fact, the article highlights a growing concern: Vitamin D is being overused, often without scientific need or personal context. At Min Vitamix, this confirms what we’ve believed from the beginning, supplements should be tailored to the individual, not taken just in case.
Why Everyone’s Taking Vitamin D
The message over recent years has been loud and clear: Vitamin D is essential. And it’s true—it supports calcium absorption, bone density, immune function, and even mood regulation. In countries with long, dark winters (like Sweden), deficiency can occur, especially in those who spend little time outdoors or have darker skin tones. But the growing awareness has led to a surge in use, often without testing or professional guidance. In fact, according to the SVT article, some pharmacy chains in Sweden have seen a 17% increase in Vitamin D supplement sales. The problem? Most healthy people don’t need extra Vitamin D, and taking it without knowing your levels can have unintended consequences.
The Risks of Overusing Vitamin D
Vitamin D is a fat-soluble vitamin, which means that unlike water-soluble ones (like Vitamin C), it’s stored in the body rather than excreted. When taken in high doses over time, it can accumulate and lead to toxicity, especially when combined with other supplements or fortified foods.
According to Professor Bergö, high levels of Vitamin D can lead to elevated calcium levels, which puts strain on the kidneys, blood vessels and heart. In extreme cases, this could lead to:
Kidney stones
Calcification of soft tissue
Impaired kidney function
Nausea, vomiting, and weakness
And perhaps more importantly, there’s no clear evidence that healthy people benefit from supplementing with Vitamin D at all.
The Smart Way to Supplement
One of the biggest problems with how we take supplements today is a lack of context. Most people don’t know their current Vitamin D levels, how much they’re getting from food or sun exposure, or whether their body even needs more.
We don’t believe in guessing. We believe in understanding. Every Min Vitamix blend is created using a detailed lifestyle questionnaire that looks at factors like diet, sun exposure, activity level, and health goals. We also offer the option to integrate your blood test results, so you know exactly where you stand before taking anything. If your Vitamin D levels are already sufficient, we won’t add unnecessary amounts. If you do need support due to low sun exposure, absorption issues, or dietary gaps, we’ll include it in a safe, balanced dose that works with your body, not against it. What the SVT article reminds us is simple but powerful: Supplements should not be taken without purpose. They are tools, not trends. And like any tool, they must be used correctly or they can cause more harm than good.
At Min Vitamix, we help you supplement with intention. Our formula gives you only the vitamins, minerals and extracts you actually need, based on your unique profile. We don’t believe in megadoses, and we don’t believe in one-size-fits-all. We believe in balance. We believe in science. And we believe your health deserves better than guesswork. Each Min Vitamix blend includes 29 high-quality micronutrients customised to your exact needs. You simply mix one scoop into water, juice, or a smoothie each day. No more pills. No more uncertainty.
