I have a collagen issue and so googled for studies about omega 3 and collagen the other day. Was surprised to find a strong negative result for wound healing and collagen formation (in mice, but the effect size means something)
It’s interesting to note the anti-inflammatory effect seems directly responsible for slowing healing (where you want it), and that this may be broadly applicable. We don’t always want less inflammation, everywhere.
For anybody without any specific issues like yours, surely this effect would be hardly observable? They administered 2 g/kg every day for four weeks, which is absolutely massive, whereas most people eating a lot of fish might be eating at most 0.05 g/kg of EPA/DHA, and that would probably only be a couple of days days a week… I take “high strength” fish oil supplements (for an autoimmune condition), and that only has 900 mg of triglycerides per capsule (1.5g of fish oil), which for me is 0.01 g/kg. I usually take two, except on days I eat salmon, when I only have one.
