For a 64-year-old individual with diabetes, the dosage of fish oil seems to vary based on different studies and health guidelines:

1. General Recommendation: The U.S. Food and Drug Administration (FDA) recommends a daily dosage of 2 to 4 grams of EPA and DHA (the active components of fish oil) for general cardiovascular health¹.

2. Specific Studies on Diabetic Patients:

   • Study 1: A study involving type 2 diabetic patients with abdominal obesity found that taking 4 grams/day of fish oil (containing 2.4 grams of n-3 PUFA) for 6 months improved triglycerides and HDL cholesterol without significantly affecting glycemic control².
   • Study 2: A meta-analysis of various studies concluded that fish oil supplementation in doses varying from 1 to 4 grams per day can help manage lipid profiles without adversely affecting glucose levels³.
   • Study 3: The National Institutes of Health (NIH) states that an adequate intake (AI) of omega-3 fatty acids for adults older than 51 years is 1.6 grams/day for males and 1.1 grams/day for females, derived mainly from ALA (alpha-linolenic acid)⁴.

Given the data, a common dosage for a 64-year-old diabetic could be around 2 to 4 grams per day, focusing on EPA and DHA-rich fish oil, to manage lipid profiles and potentially provide cardiovascular benefits⁴¹²³.

As always, it is crucial that any changes to supplement intake be discussed and monitored by a healthcare provider, especially considering individual health conditions and medications.
