Coconut Water Endurance Performance Randomized Trial: What the Evidence Says

Quick Answer

Coconut Water Endurance Performance Randomized Trial has 2 source documents in the current Migaku evidence database. The strongest available sources in this first pass are mixed biomedical and public-health sources, so conclusions should be framed as evidence-aware guidance rather than medical advice.

Key Takeaways

• This page is generated only from sources stored in the Migaku evidence knowledge base.
• Current evidence mix: 2 research article.
• Claims should be interpreted with the source type, study design, population, and publication date in mind.
• This article is educational and does not replace care from a qualified clinician.

Evidence Map

What The Sources Report

• Rockwell and colleagues found that vitamin D supplementation (vitamin D3 5000 IU/day for 12 weeks) increased fat-free mass and enhanced performance in deadlift (< 0.01) and vertical jump (< 0.01) tests compared to controls. [Jayawardena Ranil (2025); evidence level 4]
• A systematic review of 12 randomized controlled trials reported that iron supplementation in athletes improved performance in endurance sports. [Jayawardena Ranil (2025); evidence level 4]
• Several studies have reported decreased exercising HR and reduced whole-body oxygen consumption during submaximal exercise, leading to the suggestion of an improved exercise efficiency; for a review of these studies see Thielecke and Blannin 2020. [Blannin Andrew (2025); evidence level 4]
• Despite these enhanced endurance adaptations, research into whether Omega-3 fatty acid supplementation adaptations improve endurance performance is still inconclusive and could be a result of large amounts of study heterogeneity such as differences in: dose, supplementation duration, EPA: DHA ratio, training status, Omega-6 in placebo, measure of bioavailability, and performance measure (time trial (TT) vs. [Blannin Andrew (2025); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

For coconut water endurance performance randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
