Reflex Nutrition Colostrum Review

Colostrum is from UK based company Reflex Nutrition. The description of this supplement states that it can boost the immune system. This review will aim to examine each ingredient within this supplement to understand how it can achieve this claim.

Freeze dried bovine colostrum

Colostrum is a form of milk that is produced by mammals at late pregnancy. The benefits of colostrum include maintenance of the immune system, reduced upper respiratory tract infection post strenuous exercise (1, 2).

Microcrystalline cellulose

Micro Crystalline Cellulose is a non-active ingredient which is made up of refined wood pulp. This substance doesn’t degrade during digestion and is preferable in tablets due to it being able to form hard but dissolve quickly.

Magnesium stearate

Magnesium stearate does not induce any nutritional benefits. The main reason for this substance being in the supplement is that it is a lubricant for the machinery that manufactures the product.

Silicon dioxide

Silicon Dioxide doesn’t add any nutritional benefits to this supplement. The main reason for silicon dioxide in this supplement is that it aids in the even distribution of the active ingredients in this supplement.

The claim of this supplement was that it can boost the immune system.
