Core Minerals™ is iron-free for several important reasons.

First, many adults don't need supplemental iron—especially men and post-menopausal women—and excess iron can cause oxidative stress and digestive upset.

Second, iron can interfere with the absorption of other minerals like zinc and calcium.

Third, this formula is designed to work alongside detox protocols where iron could interact with binding agents.

If you need iron supplementation, you can add a separate iron supplement at a different time of day based on your healthcare provider's recommendation.

Chelated minerals are bound to amino acids or organic acids, which dramatically improves how well your body absorbs them.
Think of chelation as giving each mineral a protective carrier that escorts it through your digestive system.
For example, magnesium glycinate (magnesium bound to the amino acid glycine) is much better absorbed and gentler on your stomach than magnesium oxide.
The chelated forms in Core Minerals™ cost more to produce but provide significantly better bioavailability and fewer digestive side effects.

Taking 2 capsules twice daily (instead of all 4 at once) provides two key benefits.
First, your body can only absorb a certain amount of minerals at one time—spreading the dose maximizes absorption efficiency.
Second, split dosing maintains more stable mineral levels throughout the day, which is especially important for minerals involved in energy production, muscle function, and stress response.
This approach mimics how you'd get minerals from food throughout the day rather than all at once.

Core Minerals™ can generally be combined with most supplements, but timing matters for optimal absorption.
Take it with food to enhance absorption of fat-soluble vitamin D3 and improve mineral uptake.
If you're using binders for detoxification (like activated charcoal, clay, or products like ToxinPul), take Core Minerals™ at the opposite time of day—binders can grab onto minerals and reduce their absorption.
Space Core Minerals™ at least 2 hours away from thyroid medications, antibiotics, or bisphosphonates to prevent interactions.
