The hustle is a badge of honor these days, but if you don’t give yourself the time and tools to recover, the rewards will come at the cost of your mental and physical health. Listen to your body – it’ll tell you that it needs 7 to 9 hours of sleep every night to function at its best. This Earth Fed Essential – an advanced combination of zinc, magnesium, vitamin B6, choline and vitamin C – will help you zero in on your one true superpower: a good night’s sleep.

    1. Zinc L-carnosine is more bioavailable, and helps to balance the immune system and normalize hormone levels.
    2. Vitamin B6 Increases Serotonin - the happy hormone
    3. Contains bio-available vitamin C for nervous system recovery and immune system health
    1. Take bout 30 minutes before bedtime
    2. 150 lb adults take 2 pills
    3. 200+ lbs adults take 3 pills
    1. Immunity Boost
    2. Brain Health
    3. Reduces Inflammation
    4. Naturally increase your testosterone!

Spin on classic ZMA improved sleep quality

Surprised that changing the forms of the minerals had such an impact on sleep quality.

I was skeptical at first but after my first night I became a believer

Sleep + immunity = AMAZING PRODUCT

Before I bought this product, I loved using magnesium for a sleep aid. I regularly drank “Calm” magnesium drink..but It was lacking zinc and other vitamins this product is packed with. This is the right kind of magnesium for my sleep and it absorbs fantastically into my system. I notice I sleep poorly when I don’t have it and I make sure I take it on any trip I’m headed to if it is an overnighter.

Sleep improvement

My REM and deep sleep is improving greatly. It has gone from 20 minutes each to 1 hour or more each for the night!

Our nutritionist at my college recommended this supplement, and it's helped my sleep and foot cramps.

Works great!

Having used other ZMA's before, I was curious how this would compare. I definitely have noticed a positive shift in the quality of my sleep using this. Shipping was fast and customer service was very good. I will definitely order again!

Deeper Sleep!

Overall my sleep is deeper using this stuff and it’s actually quantified using my whoop strap. Never had any issues with it
