What are the side effects of long-term consumption of deep-sea fish oil?

Long-term consumption of deep-sea fish oil may cause some side effects, mainly including the following aspects:

1. Increased risk of bleeding: Deep-sea fish oil has anticoagulant effects, and long-term excessive intake may increase the tendency to bleed, such as gum bleeding, gastrointestinal bleeding, etc.

2. Bad breath and nausea: Deep-sea fish oil may cause bad breath or a "fishy odor" in the breath. This is mainly due to the odor produced during the oxidation and decomposition of fish oil in the body.

3. Allergic reactions: People allergic to fish or seafood may experience allergic reactions to deep-sea fish oil. If symptoms such as rash, swelling, or difficulty breathing occur, discontinue use immediately and seek medical attention.

4. Impact on blood pressure: Although deep-sea fish oil is beneficial for cardiovascular health, excessive intake may affect blood pressure stability, so individuals with hypertension should be cautious.

5. Impact on lipid metabolism: Although deep-sea fish oil helps lower blood lipids, excessive intake may disrupt lipid metabolism balance, leading to lipid abnormalities.

However, as a nutritional supplement, when used appropriately and correctly, the benefits of deep-sea fish oil generally outweigh the risks.
