Zinc Picolinate vs Gluconate
Which form is actually better absorbed?
Picolinate absorbs slightly better. Gluconate is cheaper and well-studied. For cold lozenges, gluconate is the standard. For daily supplementation, picolinate is slightly superior but not dramatically so.
Head-to-Head Comparison
Nausea if taken without food (less than other forms)
Key Fact: Studies show ~20% better absorption than gluconate. Picolinic acid is a natural mineral chelator.
Nausea if taken without food, metallic taste in lozenges
Key Fact: Most studied form for cold prevention. Cheaper and works fine for most people.
Which One For Your Goal?
| Your Goal | Winner |
|---|---|
| Best absorption | Picolinate |
| Cold prevention lozenges | Gluconate |
| Budget option | Gluconate |
| Stomach sensitivity | Picolinate |
| Correcting deficiency | Picolinate |
| General maintenance | Either |
Myth vs Reality
Myth: "Zinc oxide is just as good." Reality: Zinc oxide has poor absorption (about half of picolinate/gluconate). It's the form in cheap multivitamins and diaper cream. Skip it for supplementation.
Why Zinc Picolinate Wins
Picolinate absorbs about 20% better in comparative studies. But practically? Both work. If you're mildly deficient, either will fix it. Picolinate is worth the small premium if absorption matters (like treating deficiency).
Common Questions
Good middle ground. Better absorbed than gluconate, similar to picolinate. All three work.
The Bottom Line
Picolinate if you want the best absorption. Gluconate if you want to save money. Both beat oxide. Don't overthink it.
