Why Mineral Form Matters
Minerals are typically bound to a carrier molecule, which can influence how they are absorbed in the digestive tract. Chelated minerals — where the mineral is bound to an amino acid — are generally regarded as highly bioavailable forms. Albion®, a leading mineral research company, holds numerous patents on chelated mineral technologies that are used by several premium supplement brands.
Less expensive forms such as magnesium oxide or iron sulphate are often chosen for cost reasons but may differ in absorption characteristics and tolerability compared with chelated forms.
Magnesium — Understanding the Different Forms
Magnesium Glycinate
Magnesium glycinate combines magnesium with glycine, an amino acid naturally found in the body. It is widely regarded as a well-absorbed form of magnesium and is often chosen by individuals looking for a gentle option suitable for everyday use.
Magnesium Malate
Magnesium malate combines magnesium with malic acid, a naturally occurring compound found in many fruits. This form is commonly selected by individuals seeking a well-tolerated magnesium supplement for daytime use.
Magnesium Citrate
Magnesium citrate is one of the most widely available and commonly used forms of magnesium. It is generally well absorbed and is often chosen by individuals who prefer this established magnesium form. At higher intakes, magnesium citrate may have a laxative effect.
Magnesium Threonate
Magnesium threonate is a newer form developed through academic research. It has attracted scientific interest because of its unique transport characteristics compared with other magnesium forms and is often included in specialised nutritional protocols.
Quick Reference Guide
- Everyday use → Magnesium Glycinate
- Often chosen for daytime use → Magnesium Malate
- Commonly selected magnesium form → Magnesium Citrate
- Used in specialised nutritional protocols → Magnesium Threonate
- Sensitive digestion → Glycinate or Malate (many people prefer these forms over oxide or sulphate forms)
Iron — Gentle Forms for Sensitive Digestion
Traditional iron supplements such as ferrous sulphate are widely used but may not be equally well tolerated by everyone. Chelated forms, including iron bisglycinate, are often selected because of their favourable absorption characteristics and tolerability profile.
If you have previously experienced digestive discomfort with standard iron supplements, you may wish to discuss alternative forms with a qualified healthcare professional. Iron supplementation should ideally be based on individual requirements confirmed by appropriate testing.
Zinc — Forms and Considerations
Zinc picolinate and zinc bisglycinate are among the most commonly used forms of zinc due to their favourable absorption characteristics. Zinc oxide, often found in lower-cost supplements, is generally considered less bioavailable.
When choosing a zinc supplement, it is also worth considering copper balance during long-term use. Many practitioner-grade formulations include both minerals.
Albion® Chelated Minerals
Albion® is a mineral research company whose patented chelation technology is used by leading supplement manufacturers worldwide. Products containing Albion® minerals are typically clearly identified on the label and are often chosen by consumers looking for chelated mineral forms.
Several products in our range utilise Albion® mineral forms.
How to Choose
- Consider chelated forms such as glycinate, malate, picolinate or bisglycinate.
- Compare mineral forms rather than focusing solely on the amount of elemental mineral provided.
- Look for Albion® labelling if you are specifically seeking chelated mineral technology.
- Consider your personal preferences regarding timing and tolerability.
- Consult a qualified healthcare professional before using iron supplements or complex supplementation protocols.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. If you are pregnant, breastfeeding, taking medication or under medical supervision, consult a healthcare professional before use. Iron supplementation should be guided by a qualified healthcare professional.
