Frequently Asked Questions
How much EPA/DHA do I need for heart health?
For general heart health many experts recommend at least 250–500 mg combined EPA+DHA per day. Clinical trials for triglyceride lowering or therapeutic uses often use higher doses (1,000–4,000 mg), so check with your clinician before using high‑dose supplements.
Will fish oil give me fishy burps or indigestion?
Some people experience fishy burps with standard fish oil. Choose triglyceride‑form oils, coated 'burp‑less' capsules, or emulsified flavored liquids to reduce aftertaste. Customer reviews show these formats cut burpiness for most users.
Are third‑party tests important?
Yes. Independent testing (IFOS, USP, NSF, or similar) verifies purity and contaminant levels, ensuring low mercury and PCB content. Look for batch certificates or purity claims on the label when choosing a product.
