A systematic review and meta-analysis published in 2020 found that supplementation with nitrate did not increase the length of time people with heart failure could exercise or the distance they could walk.[1] However, currently only three randomized controlled trials have examined this topic,[1] so further research is needed to make conclusions about the effect of nitrate on exercise capacity in people with heart failure.
