Various supplements have shown potential benefits for improving working memory:

1. Citicoline: This compound may enhance human vigilance and visual working memory. It is believed to achieve this by enhancing neuronal activation and reducing oxidative stress¹.

2. Ginkgo Biloba and Bacopa Monnieri: These botanicals are commonly used as nootropics due to their potential effects on memory, concentration, and cognitive health. However, more research is necessary to fully understand their efficacy².

3. Omega-3 Fatty Acids: These essential fatty acids are thought to support cognitive function, including working memory. The combination of multivitamins, zinc, and omega-3 fatty acids has been noted to improve cognitive performance³.

4. Wasabi (6-MSITC): A study found that 6-MSITC, a compound found in wasabi, significantly improved working and episodic memory in older adults⁴.

5. Phosphatidylserine: This phospholipid may improve memory and cognitive function, although results can vary depending on individual circumstances².

These supplements are generally used with the intent of enhancing cognitive function and working memory, but it's important to consider individual health conditions and consult with a healthcare provider before starting new supplements.

When comparing omega-3 supplements to eating canned sardines, there are several considerations regarding bioavailability and nutritional benefits:

1. Nutritional Content: Omega-3 supplements, often in the form of fish oil pills, provide a concentrated dose of omega-3 fatty acids, primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Canned sardines naturally contain omega-3s and are also packed with other nutrients such as protein, calcium, and vitamin D¹².

2. Bioavailability: The bioavailability of omega-3 fatty acids varies between sources. Natural food sources like sardines often have better bioavailability due to the presence of other nutrients that aid absorption. A study comparing fish samples and cod liver oil supplements found that the bioavailability of EPA and DHA from fish was generally stable, whereas excessive quantities of oil supplements could impair absorption due to lower lipolysis³.

3. Health Benefits: Both omega-3 supplements and sardines provide cardiovascular benefits. The American Heart Association suggests consuming fish at least twice per week for optimal heart health benefits. Foods, including sardines, provide a holistic package of nutrients that might have synergistic effects beyond what supplements offer⁴.

4. Convenience and Dietary Preferences: Omega-3 supplements can be a convenient choice for those who do not consume enough fish or have dietary preferences that limit fish intake. However, it's important to consider potential differences in results as some studies suggest that consuming whole fish might have added benefits not fully replicated by supplements⁵.

In conclusion, while both options can increase omega-3 intake, consuming fish like sardines provides a broader range of nutrients and may offer better absorption and synergistic health benefits compared to supplements alone.
