At my most recent appointment with my ophthalmologist, she recommended I start taking Nuretin for lowering my risk of developing retinopathy. I didn’t see any FUD threads on it, so I figured I’d start one.
As she’d explained it (and as I understood her argument), the majority of diabetics don’t eat enough foods with omega 3’s and don’t digest/absorb them optimally.
From a JAMA Opthalmology paper:
In middle-aged and older individuals with type 2 diabetes, intake of at least 500 mg/d of dietary LCω3PUFA, easily achievable with 2 weekly servings of oily fish, is associated with a decreased risk of sight-threatening DR. Our results concur with findings from experimental models and the current model of DR pathogenesis.
Of course, this patient population doesn’t necessarily apply to me (as I’m not middle-aged nor Type 2), but promising results from a credible source (IMO, but please disagree!)
Now, that study supports the idea that omega-3s can be helpful for retinal health.
Information found from the Nuretin brochures I was given: PRN therapeutics argues that the use of Nuretin (a re-esterified omega-3 FA (EPA and DHA marine oil)) is safer than eating fish to gain omega-3 FAs because the supplements are “highly purified” … with a “NSF certified manufacturing process” that removes toxins commonly found in fish (AKA mercury.) PRN also argues that nuretin is more effective than taking other omega-3 supplements (as well as flaxseed) because nuretin is 3x more absorbable (triglyceride/rTG form) than store-bought omega 3 supplements (ester/unpurified form of omega 3 FA) and than flaxseed (plant source of omega-3s (ALA, not very absorbable)); they cited this study for their bioavailability/absorption claims
Anyways, that’s the argument I was given for nuretin. IMO it seems theoretically nice but also based on data that’s been kinda pieced together shakily. I’d love to hear everyone’s opinions
Other papers I’d found:
In an early stage of DR, supplementation with high-dose DHA plus xanthophyll carotenoid multivitamin during 90 days was associated with a progressive and significant improvement of macular function measured by microperimetry.
~apparently there’s a publication in Retina on nuretin specifically but I can’t find it and gtg but will revisit this as there’s a decent amount out there on FAs and DR/retinal health
