Plain English summary of protocol
Background and study aims
Recognizing the potential neuroprotective effect of omega-3 fatty acids administration was the foundation of the current study. The typical American diet is scarce in omega-3 fatty acids with an estimated combined intake of about 100 mg/day. As such, we sought to examine the effect of supplemental omega-3 fatty acids on changes in a surrogate biological marker of neurological injury, serum Nf-L, over the course of a competitive season in American football athletes. We hypothesized that those American football athletes supplemented with omega-3 fatty acids throughout the duration of their competitive season would exhibit lower levels of serum Nf-L throughout the course of the season compared to their counterparts not supplementing with omega-3 fatty acids.
Who can participate?
NCAA players from the selected teams
What does the study involve?
American football exposes athletes to subconcussive repetitive head impacts (RHI). Subconcussive RHI elevate serum neurofilament light (Nf-L), a biomarker of axonal injury. This study involves if Omega-3 fatty acid supplementation in American football athletes blunt the symptoms of RHI through decreasing Nf-L biomarker
What are the possible benefits and risks of participating?
Since this study does not impact the nature of American Football, there is no additional risk to be expected. Potential benefits could be that Omega-3 fatty acids improve RHI symptoms
Where is the study run from?
1. Texas Christian University, USA
2. Wisconsin La Crosse University, USA

| Scientific title | Effect of a nutritional, proprietary omega-3 fatty acid formulation on serum Nf-L levels in NCAA football athletes over the course of a season |
| Study objectives | NCAA college football athletes supplemented with omega-3 fatty acids throughout the duration of their competitive season would exhibit lower levels of serum Nf-L throughout the course of the season compared to their counterparts not supplementing with omega-3 fatty acids. |

| Intervention | Multicenter, non-randomized, interventional study design examining the effect of daily supplementation with highly bioavailable omega-3 fatty acids on plasma fatty acids levels, and peripheral levels of Nf-L over the course of an NCAA American football season. This study recruited participants from two geographically distinct NCAA American football teams. The team that received supplementation was a NCAA Division I team, while the control team competed at the NCAA Division III level. One team received treatment of omega-3 FA and the other team was control and received placebo. Blood was sampled at specific times before, during and after the during pre-season and regular season that coincided with changes in sport intensity, physical contact, and likely changes in incidence and severity of head impacts. |
| Intervention type | Supplement |
| Primary outcome measure | Serum Nf-L levels. Blood was obtained from participants at various time points chosen to coincide with changes in practice intensity, the amount of physical contact, and the number and magnitude of head impacts |
| Secondary outcome measures | Plasma fatty acids levels sampled as above |
