Muscle-Energy Support

Aspartate-led formula feeds directly into the Krebs cycle where your muscles convert fuel into usable energy.

Daily Repletion

Restocks the systemic magnesium reserves that hard training draws down over weeks.

Clean Absorption

Three chelated forms working together for complementary bioavailability.

Why This Ratio?

1. Magnesium Aspartate (250mg — 81%)

The lead form. Feeds the Krebs cycle (cellular energy production). The magnesium form with the most direct link to muscle function and reducing exercise-induced fatigue.

2. Magnesium Citrate (40mg — 13%)

Supports repletion. Highly bioavailable and well tolerated. Contributes to the daily magnesium restock that hard training draws down over weeks.

3. Magnesium Glycinate (20mg — 6%)

Supporting form. Bonded with the amino acid glycine for gentler absorption. Rounds out the formula alongside the other two chelates.

How to Take

One Scoop With A Meal

Mix with water and take with a meal. Dinner is a good default for consistency, but any meal works.

Every Day

Take it daily, not just during training days. Magnesium stores build over weeks. A day-off dose still counts.

Space from Iron

If you also take iron or Beef Liver, separate by at least two hours — the two minerals compete for absorption.

Tested. Transparent. Trusted.

What Athletes Are Saying

Verified Athlete

"I started taking this for my training and within a month my legs felt less trashed on hard days. Recovery between sessions just got noticeably easier. Not a magic pill — but you can feel the difference."

"Why lead with aspartate? Because it works. This is the first magnesium that actually feels like it was built for athletes, not for people trying to fall asleep."

Frequently Asked Questions

One scoop. That's 310mg of magnesium, about 74% of what you should get in a day. If you're a bigger athlete or training in real heat, two scoops are fine — split them across two meals instead of dumping both at once.

With a meal. Dinner works well for most people because it's the last meal of the day and easy to remember. Food helps absorption and keeps your stomach happy. Rest days count too — magnesium works over weeks, not hours, so missing a day here and there isn't the end of the world. Just take it.

Most magnesium products are built for people who want to sleep better. This one is built for people who train hard. Aspartate is the form with the strongest connection to how your muscles make energy — it delivers the magnesium and feeds directly into the process your cells use to produce ATP. Citrate and glycinate round out the formula. If you're shopping for sleep support, there are better options out there. If you're shopping to support your training, keep reading.

Probably not the way you're hoping. This isn't a sleep formula. Some athletes do sleep better on it — but usually because they were low on magnesium to begin with and being low messes with sleep. If sleep is your main goal, look at a high-dose glycinate product or something with L-threonate.

Shouldn't. One scoop with food is fine for almost everyone. If your stomach runs sensitive, take it with a bigger meal instead of a snack. Two scoops on an empty stomach can loosen things up.

Yeah. Those three are for during training. This one is for the rest of your day. Different jobs, different timing.

Electrolytes handle what you sweat out during a workout — sodium, potassium, and enough magnesium to keep you going through the session. Magnesium ACG restocks the deeper reserves your training draws down over weeks. One’s for the workout. This is for the long game. Most GOODLIFE athletes run both.

Creatine is fine — take them together, they don't fight each other. Beef Liver is different. It's a natural iron source, and iron and magnesium compete for absorption if you take them at the same time. Space them by two hours and you're good.

Depends on how low you were to start. Some athletes feel a difference in a couple weeks — legs less trashed on hard days, better recovery between sessions. For most people, magnesium is a quiet supplement. You don't feel it kick in like caffeine. You just notice, a month in, that things feel a little easier than they should. Give it 30 days before deciding.

Of course. Here are the results here.
