A small RCT says DHA during breastfeeding boosts infant brain development. A 16× larger trial disagrees.

A June 2026 Frontiers in Nutrition RCT (Gupta et al.; n=60) found that DHA supplementation during lactation significantly improved infant neurodevelopmental scores at 6 months. The far larger DHANI trial (n=957; 400 mg/day algal DHA) found no benefit at 12 months. The article breaks down both studies, explains the contradiction, and closes with a concrete recommendation: meet the 200–300 mg/day DHA threshold through fatty fish 2–3×/week or an algal supplement — but don't treat supplementation as a guaranteed developmental intervention.

Beetroot juice raises VO₂max in recreational exercisers — a 38-trial meta-analysis finally isolates the effect

A June 2026 systematic review and meta-analysis in Frontiers in Nutrition (Qin & Kim; 38 trials, 703 participants) is the first study to isolate VO₂max as a primary outcome for beetroot juice supplementation. The pooled effect is small but significant (SMD = 0.24; moderate GRADE certainty), and it concentrates almost entirely in recreational exercisers (SMD = 0.38) — highly trained athletes show no significant benefit (SMD = 0.07). Effective protocol: ≥ 6.4 mmol nitrate/day for at least 3 consecutive days, from a dose-verified source.
