Nitratena
Also known as: Nitratena, Nitrate supplements, Beetroot nitrate, Dietary nitrate, Nitrate
Overview
Nitrate is a naturally occurring compound predominantly found in leafy green vegetables and beetroot. As a dietary supplement, it is utilized for its potential health benefits, especially in enhancing athletic performance and supporting cardiovascular health. In the body, nitrate is converted to nitric oxide, a significant vasodilator that promotes increased blood flow. Research backing nitrate supplementation is robust, highlighted by systematic reviews and meta-analyses demonstrating its efficacy. The most common form of nitrate supplements is derived from beetroot juice due to its high nitrate content, making it a popular choice for athletes and those seeking cardiovascular improvement.
Benefits
Nitrate supplementation is linked with several well-supported benefits, notably in enhancing exercise performance, particularly among individuals with chronic obstructive pulmonary disease (COPD). Studies indicate a clinically significant improvement in incremental shuttle walk test (ISWT) distance by approximately 30 meters with nitrate use. Early evidence also suggests that dietary nitrate may bolster cardiovascular health, although variations exist depending on specific conditions. Observations typically occur within days to weeks after supplementation, appealing to those looking for improved physical exertion capacity.
How it works
Nitrate's primary mechanism involves its conversion to nitric oxide in the body, acting as a potent vasodilator that relaxes vascular smooth muscle. This relaxation enhances blood flow and reduces blood pressure, yielding benefits for cardiovascular health. Nitrate activates guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP) levels, which subsequently promotes vasodilation. The efficiency of nitrate and its derivatives is contingent upon proper absorption and conversion, influenced by dietary habits and gut health.
Side effects
Nitrate supplementation is generally safe when consumed in appropriate dosages. Common side effects, occurring in more than 5% of users, include gastrointestinal discomfort, taste intolerance, and beeturia, the latter being a benign condition causing reddish urine. Less common adverse effects affect 1-5% of users, with rare side effects documented in fewer than 1% of cases. Caution is advised for individuals taking phosphodiesterase type 5 inhibitors, as this combination may unexpectedly lower blood pressure. Health consultations are recommended for those with severe hypotension or under certain medications, and pregnant or breastfeeding women should seek healthcare advice before usage.
Dosage
The commonly recommended dose of nitrate supplementation ranges from 500-1000 mg per day, primarily sourced from beetroot juice or other nitrate-rich supplements. For COPD patients, specific recommendations suggest daily doses of around 250-300 mg. Nitrate is best taken prior to physical activity to maximize its effectiveness. While no established maximum safe dose exists, high doses should be monitored by a healthcare professional. Nitrate’s absorption from dietary sources is generally efficient, with no particular cofactors required, although maintaining good hydration and a balanced diet is encouraged.
