What Supplements Should You Take On A GLP-1?
A multivitamin and creatine cover the usual gaps.
Naked Creatine
Pure creatine monohydrate, a single-ingredient powder, plus a few flavoured versions.
Creatine is one of the best-studied aids for holding on to strength and lean mass, which matters most exactly when you are losing weight quickly on a GLP-1.

Naked Lean Creatine HCl
Creatine hydrochloride (Con-Cret) with prickly pear extract and added electrolytes, unflavoured or flavoured.
An HCl form of creatine that some people find easier on the stomach than monohydrate, at a smaller per-serving dose.

Life Extension Prenatal Advantage
A comprehensive multivitamin-and-mineral formula with iron, folate, iodine and other micronutrients.
When you eat much less, the vitamins and minerals that normally ride in with food shrink too. A broad multivitamin covers the gaps a smaller plate leaves behind.

Magnesium bound to glycine, a gentle, well-absorbed form of the mineral.
Magnesium is one of the minerals that runs short when appetite drops. The glycinate form is calming and is usually taken as a night-time dose.
View on AmazonLife Extension Magnesium L-Threonate
Magnesium bound to threonic acid (Magtein), a form studied for crossing the blood-brain barrier.
Another way to top up magnesium when food intake is low. The L-threonate form is usually taken as a morning dose.

A GLP-1 does not change what nutrients your body needs — it changes how much food you eat to get them. Vitamins and minerals arrive dissolved in meals, so when portions fall by a third or a half, so does the steady supply of iron, folate, B12, vitamin D, calcium, iodine and the rest. Nothing about the medication removes those needs; the shortfall is simply a side effect of eating less, and it builds slowly enough to miss.
A broad multivitamin is the simple insurance policy. It will not make up for a diet of nothing, but it covers the everyday gaps that open up when your plate shrinks, and it does so in one dose rather than a cabinet full of single-nutrient bottles. Comprehensive formulas that include iron, folate and iodine are worth looking for, since those three are among the easiest to fall short on when food intake drops and among the most consequential to miss.
Magnesium deserves its own mention because it is one of the first minerals to run short and it drives several of the symptoms people notice — cramps, poor sleep, low mood. The glycinate form is gentle and calming, which is why it is usually taken at night, while the L-threonate form is studied for crossing into the brain and is usually taken in the morning. Both are simply ways to top the same mineral back up.
Creatine sits in a different role. It is not there to fill a vitamin gap; it is there to protect performance and lean mass. Creatine monohydrate is one of the most researched supplements in existence, with a long record of supporting strength and training output. During rapid weight loss, keeping training quality up is one of the levers that protects lean tissue — and creatine helps you train harder. A few grams a day is the usual approach, and it mixes into the same shake as your protein.
Order of operations still matters. Food first, then protein to hit your daily target, then supplements to cover what is left. Supplements are the smallest lever of the three, useful for closing gaps rather than building the foundation. And if blood work shows a real deficiency — low iron or low B12, for instance — that is a medical issue to correct with your clinician, not something to self-treat with a general multivitamin.
What Do People Ask?
Why would a GLP-1 cause nutrient gaps?
Vitamins and minerals arrive with food. When appetite falls and portions shrink, the steady supply of iron, folate, B12, vitamin D and others shrinks with it.
Do I need a special GLP-1 multivitamin?
No. A comprehensive multivitamin that includes iron, folate and iodine covers the common gaps. The label matters more than the marketing.
Which magnesium should I take?
The glycinate form is calming and usually taken at night; the L-threonate form is studied for crossing the blood-brain barrier and usually taken in the morning. Both top up the same mineral.
What does creatine do here?
Creatine supports strength and training output, which helps protect muscle during rapid weight loss. It is one of the most researched supplements available.
How much creatine should I take?
A few grams of creatine monohydrate daily is the usual approach. It mixes easily into a protein shake.
Can supplements replace eating properly?
No. Food first, then protein, then supplements to cover what is left. Pills round off the edges; they do not build the foundation.
