GLP-1 medications like Mounjaro, Ozempic, Wegovy, Zepbound, Rybelsus, Trulicity, and Saxenda are transforming weight loss and metabolic health.
But they also come with unique side effects — many of which are linked to reduced appetite, lower nutrient intake, slower digestion, and changes in metabolism.

If you're on a GLP-1, understanding these side effects and supporting your body with the right nutrients is crucial.

This guide breaks down:

• The most common GLP-1 side effects

• How GLP-1s affect nutrient absorption

• Why fatigue, hair loss & low energy happen

• The nutrients people often miss on GLP-1s

• And why a clean, bioavailable multivitamin like

  is one of the most important companions to these medications

🔍 What Are GLP-1 Medications?

GLP-1 agonists include well-known brands such as:

• Mounjaro

• Ozempic

• Wegovy

• Zepbound

• Saxenda

• Rybelsus

• Trulicity

• Victoza

All of them work by:

• Slowing digestion (gastric emptying)

• Regulating blood sugar

• Reducing appetite

• Supporting weight loss

And while they are extremely effective, one thing is clear:

➤ Eating less = absorbing fewer nutrients

➤ Digesting slower = reduced nutrient uptake

➤ Rapid weight loss = increased nutrient demand

This creates the perfect storm for deficiencies — even in people who were previously healthy.

⚠️ Common GLP-1 Side Effects — And Why They Happen

1. Fatigue

One of the most reported side effects across Mounjaro, Ozempic, Wegovy, Zepbound.

Fatigue is often linked to:

• Low iron intake

• Low B12

• Low B6

• Low folate

• Low electrolytes

• Slower digestion → slower nutrient absorption

GLP-1s reduce appetite so much that people unintentionally undereat nutrition required for normal energy production.

2. Hair Thinning / Increased Shedding 

Not everyone experiences this — but people who do often ask:

“Is it the medication, or am I under-nourished?”

The answer:
Hair loss is most commonly linked to:

• Low biotin

• Low iron (very common on GLP-1s)

• Low zinc

• Low selenium

• Low protein intake

• Very rapid weight loss

These are some of the exact nutrients TRINITY supports.

3. Muscle Loss & Weakness

GLP-1s help you lose weight — but they don’t distinguish between:

• Fat

• Muscle

• Water

Low appetite = low protein intake → muscle loss accelerates.

Nutrients like magnesium, B vitamins, selenium, and iron help maintain energy production and healthy muscle function.

4. Digestive Issues (Nausea, Constipation)

Because gastric emptying slows down, digestion becomes less efficient — affecting nutrient absorption.

This is another reason a high-quality, bioavailable multivitamin is important.

🧪 Why Nutrient Deficiencies Rise on GLP-1 Medications

GLP-1s lower appetite so dramatically that many people:

• Skip meals

• Eat fewer nutrient-dense foods

• Consume smaller portion sizes

• Reduce protein intake

• Forget to supplement minerals

This leads to deficiencies in:

Most at-risk nutrients:

• Iron

• B12

• B6

• Folate

• Vitamin D

• Magnesium

• Zinc

• Selenium

• Biotin

• Electrolytes

These deficiencies directly contribute to:

• Fatigue

• Hair thinning

• Poor sleep

• Mood changes

• Muscle weakness

• Skin issues

This is where timed nutrient support becomes crucial.

⭐ Why a Multivitamin Like TRINITY Is So Important for GLP-1 Users

Most multivitamins throw everything into one capsule at the same time.
This leads to nutrient competition, especially with:

❌ iron + calcium
❌ magnesium + iron
❌ zinc + copper
❌ fat-soluble vitamins without food

But because GLP-1 users already absorb nutrients less efficiently, this competition becomes an even bigger issue.

TRINITY solves this problem with:

✔ Morning Formula (energy nutrients)

• Iron + vitamin C

• Full B-complex

• Folate

• Biotin

• Magnesium malate

• Turmeric + piperine

Boosts energy, cognition, and iron absorption — perfect for GLP-1 users feeling fatigued.

✔ Day Formula (fat-soluble vitamins + bone + immune)

• Vitamin D3 + K2

• Calcium

• Iodine

• B6 & B12

• Lutein + zeaxanthin

Helps with nutrient gaps caused by appetite suppression.

✔ Night Formula (recovery + repair)

• Magnesium glycinate

• Zinc

• Selenium

• Vitamin E

• B3 (nicotinamide)

Supports sleep, repair, hair health, and recovery.

🧠 Summary

GLP-1 medications like Mounjaro, Ozempic, Wegovy, and Zepbound are incredibly effective — but they naturally increase the risk of:

• Fatigue

• Hair thinning

• Nutrient deficiencies

• Low energy

• Digestive changes

• Muscle loss

A multivitamin that supports bioavailability, nutrient synergy, and AM/PM timing is one of the smartest tools you can use on these medications.

⭐ FAQs

Q: Do GLP-1 medications cause nutrient deficiencies?
Yes — reduced appetite and slower digestion affect nutrient intake and absorption.

Q: Why do GLP-1 users feel tired?
Low iron, B12, B6, folate, magnesium, and electrolytes contribute to fatigue.

Q: Does Mounjaro cause hair loss?
Indirectly — rapid weight loss + low nutrient intake can trigger shedding.

Q: What supplements should I take on GLP-1s?
Iron, B vitamins, magnesium, zinc, selenium, and fat-soluble vitamins are key.

Q: Why is TRINITY good for GLP-1 users?
It separates competing nutrients and supports absorption morning → night.
