FAQ

What is colloidal silver?

Colloidal silver is a suspension of tiny silver particles in ultra-pure water. It’s promoted for its natural cleansing and antimicrobial properties and is also used as a topical application for wound healing.

How do I use Nature’s Greatest Secret colloidal silver products?

Usage depends on the product:

  • Colloidal silver sprays, creams, and gels can be applied directly to the skin.
  • Colloidal silver dropper solutions offer precise application for topical use or diluted solutions.
  • Eye drops are specifically formulated for eye care and should be used following the directions provided on the packaging.
What does PPM mean?

PPM stands for ‘parts per million.’ It’s used as a unit of concentration and measures the amount of silver in a solution. A larger PPM means larger silver particles. Nature’s Greatest Secret believes 20ppm to be the optimal particle size for effective, safe colloidal silver products.

Can colloidal silver be used on pets?

Many people do use colloidal silver for pet care, and Nature’s Greatest Secret has developed a specific range for pet owners. However, it’s always best to speak to a vet before applying any product to animals.

Are Nature’s Greatest Secret products vegetarian and vegan?

Yes, their products are 100% natural, vegan-friendly, and cruelty-free.
