“…These important observations demonstrate the efficacy of fish oil, providing both EPA+DHA, to be translated from the laboratory (Hingley et al 2017) to the elite cyclist preparing and competing in a Grand Tour. Maintaining this optimal state of the O3I >8% supports of optimal skeletal muscle incorporation of EPA and DHA (Macartney et al 2019) cardiac protection (Macartney et al 2020), anti-inflammation and proresolution (Calder et al 2010), whilst achieving the personalised carbohydrate and protein nutritional goals for training, racing and recovery.…”

Background: Modifying the Omega-3 Index (O3I) in the elite endurance cyclist is desirable for cardiovascular and anti-inflammatory effects. This case study evaluated the effect of evidence based fish oil supplementation, providing long chain omega-3 eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), on three elite riders taking part in the Tour de France (TdF). Methods: The O3I of three riders was evaluated using a finger prick blood sample at the start of the season. Riders were then advised to consume daily fish oil supplements (NAMEDsport) according to their initial O3I to achieve >8% membrane EPA+DHA. Follow up blood samples were collected before and after the TdF. Results: At baseline, the O3I of rider one (R1: 6.23%) and two (R2: 6.77%) were categorised as sub-optimal (<8%) whereas rider three (R3: 9.66%) was >8%. Two daily fish oil capsules (1118 mg EPA/458 mg DHA) increased the O3I to in both R1 (8.40%) and R2 (9.69%) by the start of the TdF and this was maintained upon completion of the race (R1: 8.81%; R2: 9.37%). The O3I of R3 (9.24%) was maintained by consuming one daily fish oil capsule (559 mg EPA/229 mg DHA) in the lead up to the TdF and upon completion their O3I was similar (9.52%) despite increasing their intake to two daily capsules during the TdF. Conclusion: This case study demonstrates that an elite cyclist, consuming 1-2 daily fish oil capsules, can achieve and maintain a high O3I, in the favour of cardio-protection and anti-inflammation during arduous competition.

“…Nevertheless, athletes are cautioned against indiscriminate use of these supplements, since long-term studies on the effect of enhancing NO bioavailability are lacking. Furthermore, athletes are advised to refrain from the uncontrolled use of nitrate and nitrite salts as dietary supplements due to the potential toxicity from large doses 27. Indeed, their use is strictly regulated in the UK for this reason.…”
