The word "Immuno" appears in the product name, but the product information provided does not describe any effect on immunity. It presents the product only as a succinic acid supplement involved in normal cellular energy production, and it makes no mention of immune support. So the "Immuno" part of the name is not explained by the available product text.
In practical terms, if you are considering the product because of the name, base your choice on what the product information actually says. It may be a compact option for nutritional support during demanding periods, after travel, or when meals are irregular. If you have a specific immunity-related goal, ask a doctor or pharmacist whether this supplement is useful in your situation, rather than assuming the name reflects an effect.
It also matters that the product is a food supplement, not a medicine. It is not a substitute for a balanced diet and sensible rest, and it is not a reason to skip other steps you already take for your well-being. If you are pregnant, breastfeeding, taking medication, or have a medical condition, ask a professional before using it, and stop use if an unwanted reaction occurs.
