Why One-a-Day Multivitamins Don’t Work for GLP-1 Users
If you’re taking Ozempic®, Mounjaro®, Wegovy® or another GLP-1 medication, you’ve probably been told to “take a multivitamin” to help fill any nutritional gaps.
But here’s the problem: most multivitamins are one-size-fits-all — and one-a-day pills are especially limited.
For people on GLP-1s, whose appetite, digestion, and nutrient absorption are all being actively altered, you need a smarter approach. Here’s why standard one-a-day multivitamins fall short — and what to use instead.
🕒 1. Your Body Doesn’t Need All Nutrients at Once
Let’s start with physiology. Your body doesn’t use all vitamins and minerals at the same time of day. Some are best taken with food, some without. Some energise, others relax.
A one-a-day tablet forces everything — iron, magnesium, B12, calcium, fat-soluble vitamins, stimulants, and antioxidants — into a single dose. That can lead to:
-
Poor absorption due to nutrient clashes (e.g. calcium blocks iron)
-
Digestive irritation when heavy minerals or B-complexes are taken at the wrong time
-
Wasted nutrients, as your body excretes what it doesn’t need right then
GLP-1 users are especially sensitive to this — your system is already under nutritional pressure. A multivitamin that works with your body's rhythm is far more effective.
🚫 2. One-a-Days Often Use Incompatible or Ineffective Forms
Most one-a-day tablets are mass-produced with cost-cutting in mind. That means:
-
Synthetic versions of nutrients (like folic acid instead of methylfolate)
-
Non-chelated minerals, which are harder to absorb
-
Megadoses of some nutrients, none of others
-
Fillers, bulking agents, and binders — which GLP-1 users often can’t tolerate
For example, iron is frequently included alongside calcium — a known interaction that blocks absorption of both. Fat-soluble vitamins are often included with no co-factors or delivery system, making them near useless.
⚠️ 3. Poor Timing Can Make Side Effects Worse
Many GLP-1 users already experience:
-
Nausea
-
Stomach discomfort
-
Low energy or fatigue
-
Digestive irregularities
Taking a poorly formulated multivitamin at the wrong time can worsen all of these. B-complex vitamins, for example, should be taken in the morning to support energy — not at night when they can interfere with sleep.
TRINITY: A Multivitamin Designed to Work With Your Body, Not Against It (and perfect for Mounjaro or Ozempic users)
At Arbor Vitamins, we created TRINITY to address everything that’s wrong with generic multivitamins — especially for people on GLP-1 therapies.
Instead of one big tablet, TRINITY is a three-part system: Morning, Day, and Night capsules, each carefully paired with compatible nutrients, in optimal forms, at the right time of day.

🧠 The Science of Nutrient Timing
TRINITY supports your body’s natural circadian rhythm, which governs everything from energy to digestion to detoxification. By distributing nutrients throughout the day, TRINITY:
-
Improves absorption
-
Reduces digestive load
-
Maximises benefit at the time your body actually needs the nutrient
This is especially important for GLP-1 users, where the timing of meals — and medication — often varies.
💡 Summary: Ditch the One-a-Day, Upgrade to Trinity
If you're taking Ozempic, Mounjaro, or any GLP-1 medication, your nutritional needs are unique — and dynamic. A one-a-day vitamin isn’t just inadequate — it can actively work against what your body is trying to do.
TRINITY offers a clean, intelligent solution with:
-
No fillers or bulking agents
-
Vegan-friendly, gut-conscious capsules
-
Bioavailable, active forms of all key nutrients
-
Full B-complex, all fat-soluble vitamins, and chelated minerals
-
Timed delivery for better absorption and support
✅ Key Takeaways:
-
One-a-day multivitamins can block absorption and disrupt digestion
-
GLP-1 users benefit from nutrient timing, clean ingredients, and synergistic formulations
-
TRINITY is designed for those on modern weight loss medications — supporting your health, energy, and metabolism
