Hematogen's Dark Secret: A Sweet Treat with a Bloodline

Hematogen, the sweet treat created in Switzerland during the late 19th century, remains popular today. Though often linked to health benefits, its modern recipe has shifted from the original. Now made with sugar, starch syrup, and condensed milk, it still includes a key ingredient: dried cattle blood powder. The original formula for hematogen was quite different. Over time, manufacturers adjusted the recipe, keeping only the blood-derived powder as a nod to its past. This powder provides a small amount of iron, but nutritionists note that better sources exist.

The treat is now roughly 80% fast-acting carbohydrates and sugars. Two standard 50-gram bars deliver between 350 and 400 kilocalories. Because of this, it can cause sharp rises in blood sugar levels.

Health experts warn that certain groups should avoid hematogen entirely. Those with type 2 diabetes, insulin resistance, or metabolic disorders face risks from its high sugar content. Allergies to any of its ingredients also rule it out for some people.

Doctors suggest treating hematogen like any other sweet. They advise eating it occasionally, preferably after a full meal rather than on an empty stomach. Hematogen’s mix of sugar and blood-derived iron makes it a unique snack. While it offers a quick energy boost, its nutritional value is limited. For most people, moderation remains the safest approach.
