Manganese supplements with the fewest additives

Manganese (not to be confused with magnesium, as I often do when skimming) is important for bones, skin, and blood sugar control. However, many manganese supplements contain more than just the manganese. I try to avoid such excipients when possible. If you want to do the same, my recommendations are:

Minimal-additives manganese capsule recommendations:

Pure Encapsulations Manganese Aspartate/Citrate (Veggie Capsules)
Positives:
  • silica-free / silicon-dioxide-free
  • sorbitol-free
  • free of gums
Negatives:
  • may contain hypromellose / hydroxypropyl methylcellulose
All ingredients:

Manganese (as manganese aspartate and 50% as manganese citrate), hypo-allergenic plant fiber (cellulose from pesticide-free Southern pine, probably hydroxypropyl methylcellulose), vegetarian capsule (cellulose from pesticide-free Southern pine, probably hydroxypropyl methylcellulose, water).

Temporarily excluding NutraBio's Manganese from recommendation because of possible misrepresentation of its ingredients by their supplier.

NutraBio Chelated Manganese (Veggie Capsules)
Available on nutrabio.com
Positives:
  • silica-free / silicon-dioxide-free
  • sorbitol-free
  • free of gums
Negatives:
  • contains hypromellose / hydroxypropyl methylcellulose
All ingredients:

Manganese (as TRAACS manganese glycinate chelate), rice flour, vegetable capsule (hydroxypropyl methylcellulose).

Pure manganese powder recommendations

The serving sizes on these powders is extremely small, and manganese can be dangerous if mismeasured. Make sure to use a milligram scale for safe and accurate doses.

BulkSupplements Manganese Gluconate (Powder)
Available on Bulk Supplements
Positives:
  • hypromellose-free / hydroxypropyl methylcellulose-free
  • silica-free / silicon-dioxide-free
  • sorbitol-free
  • free of gums
  • made the the US
Negatives:
(none)
All ingredients:

Manganese gluconate powder.

A Certificate of Analysis is available.

All ingredients:

Manganese citrate, cellulose. The capsules are probably hydroxypropyl methylcellulose. The cellulose filler is derived from alpha cellulose wood pulp.
