About the Formulas

Nesi is comprised of two proprietary magnesium formulas: Boost for morning consumption, and Calm for evening consumption. Together, these two formulas are designed to boost your day by supporting energy production, cognitive function and heart health, and to calm your night by supporting relaxation, and deep, restorative sleep. 

 

Nesi Boost also contains a special ingredient called Brainberry®, which is a natural extract derived from Aronia berries. This compound crosses the blood-brain barrier, enhancing cognitive performance by improving focus, psychomotor speed, and maintaining optimal levels of brain-derived neurotrophic factor (BDNF), which is essential for brain health.

Ingredients

Boost (morning formula): DiMagenesium Malate, Magnesium Bisglycinate Chelate, SolarSea® AC (magnesium + trace minerals), and Brainberry® (for cognitive support). 

 

Calm (evening formula): Magnesium Pidolate, and Magnesium Bisglycinate Chelate, and SolarSea® AC (magnesium + trace minerals).

Why You Feel Constant Stress No Matter What

Chronic stress depletes key minerals your body needs to stay calm. Without enough magnesium, your nervous system struggles to relax, leaving you feeling wired, tense, and on edge. Magnesium is often the missing piece to feeling your best during the day, without the stress.

Why Nesi is different

Here's why Nesi is different than cheap single-source magnesium brands:

Multiple forms of magnesium to support energy during the day, and relaxation, and deep sleep at night.

SolarSea® AC Magnesium + Trace Minerals (improves absorption so your body actually uses it)

Includes Brainberry® in the morning formula, to support mental energy and improved cognitive function.

Our Story

A Passion-Driven 
Health Journey 

Nesi was born out of our own personal health journeys. We are a team who is dedicated and passionate about our health, and committed to becoming just a little bit healthier and better each day. When we discovered how critically important magnesium is to overall health we immediately started taking it regularly. We then realized that magnesium is a rather ambiguous product category, with so many different types to choose from, and so many different brands.

 

Our mission is simple: to simplify magnesium supplementation into one complete product, for morning and evening consumption. Made from the highest quality ingredients, with high bioavailability, we wanted to build a product that we ourselves wanted to take. We built this for us, and for people like us, those who want to be their healthiest and feel their best.
