The 7 Nutrients You Lose on GLP-1 — And How to Replace Them

A GLP-1 medication doesn't just change how much you eat — it changes what your body has to work with. When portions shrink, so does your intake of the vitamins and minerals that keep your energy, mood, hair and muscles running. Here are the seven that matter most, and how to top them back up.

1. Vitamin B12

B12 powers energy production and nerve function, and it's one of the first to dip when you eat less meat, eggs and dairy. Low B12 shows up as fatigue and brain fog. Look for the methylcobalamin form — it's more usable than cheap cyanocobalamin.

2. Iron

Less food, especially less red meat, means less iron — and iron is what carries oxygen to every cell. Low iron feels like tiredness that sleep doesn't fix. Ferrous bisglycinate is a gentle, well-absorbed form that's easier on a sensitive stomach.

3. Magnesium

Magnesium is involved in hundreds of processes, including muscle relaxation and — importantly for GLP-1 users — regularity. It's one of the most commonly under-consumed minerals even in people eating normally.

4. Vitamin D3

Most people are already low in D3, and eating less doesn't help. D3 supports immunity, mood and bone health. It works best paired with magnesium and K2.

5. Zinc

Zinc supports immunity, skin, hair and taste. If food is tasting flat or your hair feels thinner, low zinc may be part of the story. Zinc bisglycinate absorbs well without the nausea some forms cause.

6. Folate

Folate works hand-in-hand with B12 for energy and cell production. The L-5-MTHF (methylfolate) form is active and usable by everyone, including people with the common MTHFR gene variation.

7. B6

B6 supports mood, sleep and the metabolism of protein. The P-5-P form is the one your body uses directly.

The simplest way to cover all seven

You could buy seven bottles. Or you could take one formula built to replace exactly these nutrients in their bioavailable forms.

That's the entire idea behind Wellura GLP-1 Support: methyl-B12, ferrous bisglycinate iron, magnesium, D3, zinc bisglycinate, methylfolate and P-5-P B6 — plus a digestive-comfort blend and BioPerine® for absorption — in two capsules a day.

How to know it's working

Give it 3–4 weeks of consistent daily use. Most people notice steadier energy first, then better digestion and mood. Replenishment isn't a one-day fix — it's a refill that builds over time.
