Zeroing in on the suitable, effective and safe dietary source of nitrate is as important as understanding its importance in improving ones health.
Although, currently a lot of natural sources of nitrate are available in the market, not all of them have safety and efficacy profiles on par with beetroot extract that make them suitable for human consumption.
A typical example would be the use of Amaranthus dubius, commonly known as red spinach. While this species of spinach is a rich source of nitrates, it also comes with several disadvantages, such as the presence of oxalates and hydrocyanic acid, which are found to be detrimental to health. It is also not a clinically well documented source of nitrate for safe consumption. Beetroot extract, thus remains a preferred and safe nutrient choice for its varied health benefits.
