IN-HOUSE CHELATION
IN-HOUSE CHELATION
Chelation is a chemical reaction between a mineral, like magnesium, and a ligand, like glycine. With our mag gly, we achieve chelation with only magnesium, glycine, heat, and water (no additional materials or carriers) in our GMP facility certified by NSF in Utah.
To our knowledge, we are the only U.S. supplement finished product manufacturer with its own in-house proprietary chelation process. This allows us to control and test the inputs and outputs, and triple verify for the right ratio, right process, and right bonds, to produce a truly excellent magnesium supplement.

Frequently Asked Questions
What is Solaray Colostrum+ with ImmunellTM?
Solaray Colostrum+ with ImmunellTM is a convenient, once-daily powder supplement that combines responsibly sourced, bovine colostrum from grass-fed cows and ImmunellTM, a unique nucleotide complex derived from dried brewer’s yeast to give you the daily support you need.
What is bovine colostrum?
Bovine colostrum is the milk produced by cows during the first few days after birth.
Why is colostrum called nature’s superfood?
Colostrum is called nature’s superfood because it is a rich source of bioactive molecules including macro- and micro-nutrients. It is also naturally able to maintain its bioactivity until it reaches the gut region.
What are nucleotides, and why are they added to Colostrum+?
Nucleotides are the basic building blocks of nucleic acids (RNA and DNA). They are essential for cellular functions that govern growth, reproduction, and the storage and transmission of genetic information. We added them to Colostrum+ to complement the bioactive molecules found in bovine colostrum.
Why combine colostrum with ImmunellTM?
Colostrum already contains multiple components including nucleotides. An additional nucleotide component, like ImmunellTM, provides a higher supplemental dose of these essential building blocks.

Who should talk to a healthcare professional before taking colostrum supplements?
Always ask your healthcare provider before starting a new supplement, especially if you are pregnant, nursing, or are on daily medications. If you’re taking prescription medications, consult your healthcare provider in advance to avoid any potential interactions.
Colostrum supplements are not suitable for individuals with allergies to cow’s milk. Because its effects on fetal health are still unknown, colostrum should not be taken while pregnant or breastfeeding.
