The potential side effects associated with 'Mega Man' depend entirely on which product is being referenced: the widely available GNC Mega Men multivitamin or the recalled MegMan Performance Booster. The confusion between these similarly named products highlights the importance of scrutinizing health supplements and understanding their contents.
Side Effects of GNC Mega Men Multivitamin
GNC Mega Men is a dietary supplement containing a blend of vitamins and minerals intended to support overall health. As with any multivitamin, it can cause mild to moderate side effects, especially as the body adjusts to the intake of various nutrients.
Common side effects
- Gastrointestinal Upset: Some individuals may experience mild stomach discomfort, constipation, or diarrhea. This is often temporary and can be minimized by taking the supplement with food.
- Nausea: Feelings of nausea are a reported side effect for some users, which can also be addressed by taking the supplement at mealtime.
- Urine Discoloration: High doses of B vitamins, particularly riboflavin (Vitamin B2), can cause urine to become a bright, fluorescent yellow color, which is a harmless, temporary effect.
Rare or severe side effects
- Allergic Reaction: In rare cases, a serious allergic reaction can occur. Symptoms include rash, itching, swelling of the face or throat, severe dizziness, or trouble breathing. Immediate medical attention is required.
- Fatigue: Some users have reported experiencing unusual fatigue, which may subside after discontinuing the supplement.
- Abdominal Cramping: In more severe cases, some individuals have experienced significant abdominal cramping and bloating.
Drug interactions
Multivitamins can interact with other medications, potentially affecting their efficacy. It is crucial to consult a healthcare professional, especially when taking prescription drugs for conditions such as heart disease or kidney issues, as some vitamins and minerals can pose risks at high doses.
Side Effects of Recalled MegMan Performance Booster
In stark contrast, the product known as "MegMan Performance Booster" was the subject of an FDA recall because it contained undeclared drug ingredients. It is crucial to understand the severe and potentially life-threatening side effects associated with this adulterated supplement.
Recall information
- Hidden Ingredients: The product was found to contain Tadalafil, a phosphodiesterase (PDE-5) inhibitor used in FDA-approved prescription drugs for erectile dysfunction. Some similar products have also been found to contain Sildenafil (Viagra's active ingredient).
- Unapproved and Unsafe: Because these prescription ingredients were undeclared, the safety and efficacy of the product were never established. The FDA issued warnings urging consumers to avoid such products.
Serious and life-threatening side effects
- Dangerous Drop in Blood Pressure: PDE-5 inhibitors like Tadalafil and Sildenafil can interact with prescription drugs containing nitrates (used for heart conditions) to cause a severe and life-threatening drop in blood pressure.
- Cardiovascular Risks: The hidden ingredients pose serious health risks for people with diabetes, high blood pressure, high cholesterol, or heart disease.
- Allergic Reactions: Like the multivitamin, the undeclared ingredients could trigger allergic reactions.
- Other Serious Effects: Since the ingredient levels were unregulated, the risk of serious side effects like heart attack, stroke, prolonged erection, or mood swings was also present, as seen with prescription versions of these drugs.
Comparing GNC Mega Men and Recalled MegMan Booster
| Feature | GNC Mega Men Multivitamin | Recalled MegMan Performance Booster |
|---|---|---|
| Product Type | Dietary Supplement (multivitamin) | Sexual Enhancement Supplement (adulterated) |

Conclusion
The most important takeaway is to distinguish between the legitimate GNC Mega Men multivitamin and the recalled, dangerous MegMan Performance Booster. While the GNC multivitamin carries the standard risk of mild side effects common to such supplements, the recalled booster represents a serious health hazard due to its undeclared prescription drug content. Always read product labels, purchase from reputable sources, and consult a healthcare provider before taking any new supplement, especially if you have pre-existing health conditions or are on other medications.

Important Safety Measures for Supplement Use
- Read Labels Carefully: Always check the ingredient list to ensure you know exactly what you are consuming.
- Consult a Professional: Speak with a doctor or pharmacist before starting any new supplement regimen, especially if you have underlying health conditions.
- Buy from Reputable Sources: Avoid buying supplements from unverified online sellers or other sources where adulterated products are more likely to be sold.
- Recognize Red Flags: Be wary of products with suspiciously fast-acting or extraordinary health claims, as these may contain hidden drug ingredients.
- Report Adverse Effects: If you experience a negative side effect from a supplement, report it to the FDA through their MedWatch program.
By following these precautions, consumers can protect themselves from the risks associated with unregulated and potentially harmful products.
Symptoms of Multivitamin Overdose
Exceeding the recommended dosage of any multivitamin, including GNC Mega Men, can lead to nutrient toxicity. Symptoms can include stomach pain, nausea, vomiting, and diarrhea. In severe cases of mineral toxicity, particularly with iron, the effects can be more serious. Always follow the recommended dosage instructions.
Importance of Professional Advice
Dietary supplements are not a substitute for a balanced diet and are not strictly regulated by the FDA in the same way as medications. A healthcare professional can help you determine if a supplement is appropriate for your individual needs and can check for potential drug interactions.
