DHA Case Study
Just added this to Omega-3 Fatty Acid Recommendations for Vegetarians at VeganHealth.org:
A 60 year old, male, long time vegan forwarded his fatty acid lab reports to me. In August 2012 his EPA levels were .3% and DHA was 1.0% (of fatty acids in blood). He had been using “a lot of” canola oil but it apparently wasn’t increasing his EPA and DHA levels. After six months of daily supplementation of 320 mg DHA plus 130 mg of EPA (one capsule of Ovega-3 vegan supplement), his EPA levels went to 1.0% (about average for omnivores) and DHA to 4.8% (towards the higher average range for omnivores). It appears that this regimen was adequate.
