FAQ
What differentiates this colloidal chromium from other products on the market?
Our ionic-colloidal chromium is produced using high-precision electrolysis technology and consists of 99.99% pure chromium in ultrapure water (Type 1*). Unlike many other products, we completely refrain from using additives, preservatives, or stabilizers. Each batch undergoes strict quality controls to ensure the highest purity and stability.
How is the product used, and how long does one bottle last?
There is no general consumption recommendation for ionic-colloidal chromium, as it is used individually. A 1000 ml bottle lasts several weeks to months, depending on usage. If you have questions about its use, we recommend consulting a specialist doctor or therapist.
Is the product really completely pure and free of additives?
Yes! Our product contains exclusively chromium in ionic-colloidal form and the purest water – nothing else. It is free from preservatives, binders, or stabilizers. Through strict purity controls and the use of ultrapure water, we guarantee the highest quality.
How should colloidal chromium be stored to maintain its quality?
The product should be stored in a cool, dry, and dark place – meaning not in the refrigerator, but at room temperature. Direct contact with metal should be avoided, as this can affect the ionic structure. After opening, it is shelf-stable for up to 3 months.
