Is there sufficient evidence to supplement omega-3 fatty acids to increase muscle mass and strength in young and older adults?

What is your doctors' prescription to stop your muscle atrophy? ANYTHING AT ALL? Or head in the sand behavior by your doctor?

Maybe something in  these muscle atrophy posts?

  For each day a patient is in hospital lying in bed with minimal activity approximately 13% of muscular strength is lost (Ellis, Jackson, Liu, Molloy, & Paterson, 2013).

 

I have 69 posts on Omega-3s with lots of benefits. Ask your doctor for an analysis. Followup needed which will never occur since we have NO STROKE LEADERSHIP to go to for anything.

 

Is there sufficient evidence to supplement omega-3 fatty acids to increase muscle mass and strength in young and older adults?




Summary

Omega-3 (ω-3) is a polyunsaturated fatty acid with anti-inflammatory properties that presents three main forms: alpha-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid. Recently, studies performed in both young and older adults suggest that ω-3 may improve gains in muscle mass and/or enhance physical function. Thus, the aim of this narrative review was to evaluate the current evidence of ω-3 intake/supplementation on muscle/lean mass (LM) and physical function in young and older adults, and draw research-based conclusions as to the practical implications of findings. We first assessed whether ω-3 intake is associated with muscle mass and strength (observational studies), and then sought to determine whether evidence shows that supplementation of ω-3 increases muscle protein synthesis, LM and strength in adults and older adults (interventional studies). The search was carried out in PubMed and Scopus databases for the periods between 1997 and November 2018. The following keywords were used alone and in combination: ω-3, fish oil, muscle protein synthesis, muscle mass, lean mass, body composition, and physical function. In general, ω-3 supplementation does not seem to promote increases in muscle mass in sedentary young and older adults; the hypertrophic effects of supplementation when combined with resistance training remain equivocal. Moreover, there is conflicting evidence as to whether supplementation confers a beneficial effect on muscle function in older adults. Importantly, this conclusion is based on limited data and more studies are needed before ω-3 supplementation can be recommended as a viable strategy for such purposes in clinical practice.
