Common Gastrointestinal and Other Mild Side Effects
For most people, any side effects from taking Conzace are mild and temporary, often resolving as the body adjusts to the supplement. The most frequently reported issues involve the digestive system.
Common side effects may include:
- Gastrointestinal discomfort: Nausea, vomiting, abdominal pain, intestinal cramps, and diarrhea are some of the most frequently cited adverse reactions. Taking the supplement with a meal, as recommended, can help minimize this discomfort.
- Headache: Some individuals report experiencing headaches after starting Conzace.
- Metallic or unpleasant taste: The zinc content can sometimes cause a temporary, metallic, or altered sense of taste.
- Drowsiness or insomnia: While less common, some users experience changes in their sleep patterns, including drowsiness or difficulty sleeping.
- Loss of appetite: Alterations in appetite have been reported in some instances.
- Skin rash: Skin-related reactions like a rash can occur, and while often minor, should be monitored.
Serious Adverse Reactions and Overdosage
While rare with proper use, serious side effects and reactions to overdosing can occur, often due to the high potency of certain vitamins in the supplement.
Allergic Reactions
Like any medication or supplement, a severe allergic reaction is possible. You should seek immediate medical help if you experience signs of an allergic reaction, which include:
- Rash, hives, or itching
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing or tightness in the chest
- Severe dizziness
Effects of High-Dose Vitamins and Zinc
Conzace contains high concentrations of certain vitamins, and prolonged intake or exceeding the recommended dose can lead to potential toxicity.
- Vitamin A (Retinol Palmitate): Chronic daily intake of excessive amounts of Vitamin A can lead to hypervitaminosis A. Symptoms can include fatigue, irritability, lethargy, blurred vision, headache, nausea, vomiting, abdominal pain, and in severe cases, liver damage. Pregnant women especially must avoid excessive Vitamin A due to the risk of birth defects.
- Vitamin E (dl-alpha Tocopheryl Acetate): High doses of Vitamin E can act as an anti-vitamin K agent, increasing the risk of bleeding. This is particularly concerning for those on anticoagulant medications like warfarin.
- Vitamin C (Ascorbic Acid): Prolonged intake of very high doses of Vitamin C can lead to severe diarrhea, abdominal cramps, and may increase the risk of oxalate-containing kidney stones in individuals with pre-existing kidney disease.
- Zinc (as Sulfate): Signs of acute zinc toxicity from excessive doses include severe GI pain, nausea, vomiting, and diarrhea. Long-term, high-dose zinc supplementation can lead to copper or iron deficiency, anemia, and reduced HDL cholesterol levels.
Drug Interactions with Conzace
The vitamins and minerals in Conzace can interact with various medications, affecting their absorption or effectiveness. It is crucial to inform your doctor about all medications and supplements you are taking.
- Anticoagulants (e.g., Warfarin): High doses of Vitamin E and Vitamin A can increase the risk of bleeding in patients taking blood thinners.
- Antibiotics (e.g., tetracyclines, quinolones): Zinc can interfere with the absorption of certain antibiotics. To minimize this, take the antibiotic at least 2 hours before or 4 to 6 hours after taking the zinc supplement.
- Retinoids (e.g., isotretinoin): Avoid using Conzace with other retinoid medications, as it can lead to additive toxic effects from the Vitamin A.
- Antacids: The concomitant use of Vitamin C and antacids can increase the risk of aluminum toxicity, especially in patients with renal insufficiency.
Who Should Avoid Taking Conzace?
Certain populations should avoid or use Conzace with extreme caution and under strict medical supervision due to the risks associated with its ingredients.
- Pregnant and Breastfeeding Women: The product is contraindicated during pregnancy due to the high dose of Vitamin A, which can cause birth defects. Women who become pregnant while taking Conzace should stop immediately and consult their doctor.
- Individuals with Allergies: Anyone with a known allergy to any of the ingredients in Conzace should not take the supplement.
- People with Specific Health Conditions: Caution is advised for those with kidney disease, liver failure, hemochromatosis, or glucose-6-phosphate dehydrogenase (G6PD) deficiency.

| Vitamin E | Rash, nausea, diarrhea. | Increased bleeding risk, especially with anticoagulants like warfarin. |
| Zinc | Nausea, vomiting, upset stomach, diarrhea, metallic taste, headache. | GI pain, nausea, vomiting, long-term copper/iron deficiency, anemia, reduced HDL cholesterol. |
Conclusion
While generally safe and effective for immune and skin health, understanding what are the side effects of taking Conzace is vital for safe supplementation. Most side effects are minor and related to gastrointestinal issues, especially with zinc and vitamin C intake. However, exceeding the recommended dosage or ignoring contraindications can lead to serious adverse effects, including vitamin toxicities and dangerous drug interactions. Always consult a healthcare professional before starting or altering your supplement regimen, particularly if you have pre-existing health conditions or are taking other medications, as highlighted by resources like the Philippine Drug Monograph. Your doctor is the best source for personalized medical advice to ensure the supplement is appropriate for your specific health needs.
