Supplement Needs H2Out Diuretic

Like all Supplement Needs products, H2Out is a fully transparent, non-proprietary water balance product. H2Out includes 14 ingredients, all well dosed, in a berry flavoured powder drink, part of the Supplement Needs Performance range. It’s the perfect addition when you need that extra edge for water manipulation in competitive sport, whether that’s for visual display in bodybuilding or weight class management for combat sport.

H2Out is formulated by Dean St Mart, using 9 natural herbal ingredients alongside Vitamin B6, PurCaf, Potassium, Magnesium, Calcium and Calcium D-Glucarate. Combined, these ingredients help to support water loss from the kidneys, help with electrolyte balance and support phase 2 estrogen metabolism.

This product has been specifically designed to stack well with Electrolyte+ and Astra G-Flow powder to create a comprehensive stack that serves water manipulation goals while ensuring electrolyte balance and kidney function is supported.

Please note, H2Out is designed to be used for brief periods of water balance manipulation only. Do not use 3 servings per day for more than 5 consecutive days.
