Bovine Colostrum Capsules - 500mg – 30% IgG Immunoglobulin Formula

Bovine Colostrum Capsules 500mg with 30% Immunoglobulin G (IgG) — a daily supplement for adult immune, gut, and recovery support.

Looking for a real-dose colostrum supplement that tells you exactly how much IgG you are getting? This is a 500 mg bovine colostrum formula standardized to 30% Immunoglobulin G, made in the USA for adults who want a straightforward daily source of colostrum's natural bioactive compounds. No filler-heavy blends, no vague "proprietary" math — just transparent dosing on the label.

Colostrum is the first milk produced by mammals in the hours and days after birth. It is naturally dense with antibodies, growth factors, and bioactive compounds — the biological starter kit that helps newborns get their immune and digestive systems online. For decades, bovine (cow) colostrum has been studied as a food supplement for adults, and it has found a steady place in the routines of athletes, older adults, and people focused on gut wellness.

The key marker people look for on a colostrum label is IgG — Immunoglobulin G — because that is the antibody fraction most research has focused on. Our formula is standardized to 30% IgG, which is a meaningful, labeled percentage, not a "trust us" claim.

What is this for?

This supplement is for adults who want a clean, honestly-labeled source of bovine colostrum as part of a daily wellness routine. It is a common pick for three overlapping groups: people focused on immune wellness, people working on gut health, and people with active lifestyles who want support for post-exercise recovery.

Colostrum's naturally occurring immunoglobulins help support the body's own immune defenses. Its bioactive compounds are associated with gut lining support and normal digestive function. And its growth factors are the reason many active adults reach for it after training sessions — to help maintain normal recovery as part of their routine.

Put simply: this is a single-ingredient colostrum supplement built for people who want the real thing, clearly dosed, without extras they did not ask for.

What is inside?

No proprietary blends. No hidden math. One active ingredient, clearly listed — exactly the way it should be.

Each one-capsule serving delivers:

1. Bovine Colostrum — 500 mg, standardized to 30% Immunoglobulin G (IgG). Sourced from dairy cattle, the same origin used in virtually all quality colostrum supplements on the market.

What else is in the capsule: Gelatin (bovine) for the capsule shell, Vegetable Magnesium Stearate (a processing aid), and Silicon Dioxide (a flow agent). That is it. Nothing hidden.

What you will not find inside: artificial colors, synthetic dyes, GMO ingredients, or proprietary blends that hide the real numbers.

Please note: this product contains milk (colostrum is a dairy-derived ingredient) and the capsule shell is bovine gelatin, so this formula is not suitable for vegan, vegetarian, or dairy-free diets.

Can I trust it?

Fair question. Here is what we do to earn that trust.

1. Made in the USA in a facility that follows current Good Manufacturing Practices (cGMP).
2. Clearly labeled IgG content. 30% IgG is printed on the label — not hidden in a blend.
3. Single-ingredient formula. No "boosters," "activators," or mystery co-factors that let us charge more without adding real value.
4. Certificate of Analysis available on request. We test our batches, and we are happy to share the paperwork. Contact us and we will send you the CoA summary for this product under a standard confidentiality agreement.

We believe supplements should be held to the same standard as the food on your kitchen counter. That means nothing to hide on the label and nothing complicated to explain to your doctor.

What this formula is built for:

1. Muscle Recovery — colostrum contains growth factors studied for their role in post-exercise recovery
2. Gut Microbiome — naturally occurring bioactive compounds support the gut environment
3. Immunity Boosting — IgG antibodies support the body's natural immune defenses
4. Holistic Health — a whole-food–style bioactive ingredient with a long history of use
5. Men's Health — suitable for daily use by adult men
6. Women's Health — suitable for daily use by adult women
7. Non-GMO

A note on what this formula is not: this product is not vegan, not vegetarian, and not dairy-free. The colostrum itself is bovine (dairy-derived), and the capsule is bovine gelatin. If you follow a plant-based diet or have a dairy allergy, this is not the right supplement for you.

How do I take it?

One capsule, one to three times daily, preferably with meals. Most people start with one capsule a day alongside breakfast, and some adjust upward based on how they feel and how they are using the product (for example, active adults often take more around training days). If your healthcare provider has suggested a different schedule for you, follow their lead.

The capsules are a standard size, easy to swallow, and have no taste or aftertaste.

One bottle contains 60 capsules — a 20 to 60-day supply depending on your chosen daily serving.

Why choose this one?

There are a lot of colostrum supplements on the shelf right now. Here is where ours stands apart.

Many colostrum products on the market list just "colostrum" with no IgG percentage — which is a red flag, because IgG content can range widely from one product to another. Ours is clearly labeled at 30% IgG on 500 mg of colostrum. You know what you are buying.

A lot of brands also bundle colostrum with five or six other ingredients, then charge a premium for the combination. We went the other direction. This is a single-ingredient colostrum supplement, priced for daily use, giving you the flexibility to stack it with other products if you want to — or keep it simple.

You are also not paying the premium that trending wellness brands often charge just because colostrum has become popular on social media. We priced this where we believe a clean-label, transparently-dosed formula should sit: fair for what is in the bottle, sustainable for daily use.

Clean label. Full disclosure. Made in the USA. That is the whole offer.
