Colostrum supplements are usually made from bovine colostrum, the early milk produced after calving. People typically take them for immune support, gut health, athletic recovery, and intestinal permeability support.
Colostrum products vary more than the front label often suggests. Some are simple bovine colostrum powders, some are capsules that require several pills per serving, and some call out immunoglobulin or IgG content as a quality marker. That makes the cost-per-month view more useful than comparing bottle price alone.

Check the actual colostrum amount per serving. Many labels list 1 g, 1.5 g, 2 g, or 3 g per serving, and capsule products may require two to six capsules to reach that serving. A bottle with a high capsule count can still be expensive at a 3 g/day target if each serving is small.
Look for clear IgG or immunoglobulin information. Colostrum is often marketed around immunoglobulins, especially IgG. Better labels may state the colostrum amount and the IgG percentage or amount, such as 20-30% immunoglobulins or a stated IgG milligram amount. This helps distinguish a transparent product from one that only says "colostrum" without potency context.
Do not confuse IgG with an extra ingredient. Some labels list bovine colostrum first and then show immunoglobulins or IgG underneath it. In that case, IgG is usually a component of the colostrum, not a separate added ingredient. The key comparison number for this page is the bovine colostrum amount, while IgG details are useful quality context.
Powder is not always cheapest, but it is often easier to dose flexibly. Powders can make it simpler to hit a 3 g/day target without swallowing several capsules. Capsules are more convenient, but the cost depends heavily on how many capsules make one serving and how much colostrum each serving provides.
Sourcing and processing claims matter, but price still needs normalization. Common claims include grass-fed, pasture-raised, New Zealand or Australia sourcing, no fillers, gluten-free, GMP manufacturing, and early-harvest or "6-hour" colostrum. These can be useful quality signals, but they do not replace checking dose, servings, and monthly cost.
Watch for extra ingredients. Most colostrum products are straightforward, but some include small supporting ingredients such as black pepper extract. That does not automatically make the product bad, but it is worth noting if you want a simple bovine colostrum supplement or if you avoid certain additives.
IgG is one of the most common quality signals on colostrum labels. A product that lists both total colostrum and IgG content gives you a clearer view of what you are buying. For example, a 2 g serving standardized to 30% IgG implies about 600 mg of IgG, while a 1 g serving standardized to 25% IgG implies about 250 mg.
That does not mean the highest IgG label is automatically the best choice for everyone. Total dose, price, sourcing, form, and tolerance all still matter. But when two products have similar monthly cost, a clearer IgG disclosure is a useful tie-breaker.
Colostrum has moderate evidence compared with many supplement categories. Human studies are strongest around immune function and gut permeability in athletes, with growing but still more limited evidence for general immune support. The tables use 3 g/day as a consistent comparison point, not as a guarantee that this is the right dose for every person.
Colostrum is milk-derived, so people with milk allergy should avoid it unless a clinician says otherwise. People who are pregnant, immunocompromised, managing autoimmune conditions, or using complex medication regimens should talk with a healthcare professional before using colostrum. Claims around immunity, gut repair, or athletic recovery should be treated as context for why people buy it, not as a guarantee that a supplement will produce those effects.
