Transfer Factor Classic is built around cow-colostrum-derived Transfer Factor material in a vegetable-capsule format. It is the simpler original formula compared with Tri-Factor and Plus.
The current U.S. label should be checked because ingredient statements and capsule details may change.
Primary ingredient
The defining ingredient is cow-colostrum-derived Transfer Factor.
Colostrum contains many proteins and peptides. The proprietary ingredient should not be assumed to be identical to ordinary whole-colostrum powder.
What Classic does not center on
Compared with newer formulas, Classic does not center on:
- OvoFactor from egg yolk;
- NanoFactor;
- zinc;
- a mushroom blend.
This simpler profile can make comparison easier.
Other ingredients
Vegetable capsules still require additional manufacturing ingredients.
Check the label for:
- capsule material;
- flow agents;
- stabilizers;
- any regional differences.
Milk allergen
Because the product is colostrum based, milk allergy is a central concern.
Processing should not be assumed to remove all allergenic proteins.
Is there lactose?
The current label should answer the practical question. Lactose intolerance and milk-protein allergy are not equivalent.
Ingredient transparency
A consumer should be able to identify:
- amount per capsule or serving;
- serving size;
- source;
- other ingredients;
- allergen statement;
- manufacturing information.
Classic vs ordinary colostrum
A generic colostrum powder may emphasize total grams or immunoglobulin content. Classic emphasizes proprietary Transfer Factor material.
The products should not be treated as dose-equivalent.
Classic vs Tri-Factor
Tri-Factor broadens the proprietary system with egg-yolk-derived and small-molecule components.
That does not make one universally better. It makes the formulas different.
Bottom line
Classic is the simplest cow-colostrum-focused core product. Its main ingredient questions are source, amount, milk allergen, capsule materials, current directions, and evidence for the finished product.
