Product Overview

NOW Magnesium 400 mg Enzyme Function Nervous System Support is a great product for anybody wanting to increase their magnesium intake. It contains 400 mg of magnesium, so it s sure to provide the necessary amount of magnesium for those looking to support their energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization. It s also a required cofactor for an estimated 300 enzymes and can help with fatty acid synthesis, protein synthesis, and glucose metabolism.

The NOW brand has been around since 1968 and has been known for providing quality products. This product is no exception it is certified Kosher, Vegan, Soy Free, Keto Friendly, Non GMO, and Halal. It is also GMP Quality Assured with an NPA A rated GMP certification meaning that every aspect of the NOW manufacturing process has been examined.

The capsules are easy to swallow and are a great value for money due to the 180 count bottle it comes in. I did not experience any change in sleep quality from taking this product but I can definitely tell that my body is absorbing the magnesium as I can feel its effects throughout my body. The capsules do not have any flavor so if you don t like taking pills then this isn t the best product for you.

I would recommend this product to anybody who wants to increase their magnesium intake but doesn t want to take unpleasant tasting liquid supplements or gummies that are full of sugar or questionable ingredients. It is a great option for anyone looking for a quality supplement at an affordable price point especially vegans or people with dietary restrictions as this product fits all of those requirements!
