The Real Root Cause Nobody Checks: Your Gut Lining

Your gut lining is a wall just one cell thick. Stress, medications, processed food and age wear it down until tiny gaps open and it starts to leak. Toxins slip into your blood. Inflammation never shuts off. Nutrients pass right through. That's the bloating that never leaves, the 3 PM crash, every bug, the tired skin and hair. It's not your age or your willpower. It's a leaking wall, and fiber or probiotics can't seal it.

Seals the Gut That's Connected to "Everything"

Your gut lining is just one cell thick, held together by tight junctions. When those junctions loosen, LPS toxins from gut bacteria slip into your blood and spark inflammation everywhere. Colostrum's IgG binds those toxins before they cross, while its growth factors rebuild the junctions and seal the wall. Creating a domino effect on your entire body. About 70% of your immunity lives in your gut, so once it's sealed, your energy, skin, hair and nails follow.

Colostrum Is the First Food Your Body Ever Knew

Every mammal on earth starts life on colostrum. It's nature's design to seal a newborn's wide-open, permeable gut in the first hours of life, which is why your body recognizes it instantly. First-day bovine colostrum carries 400+ bioactives in their natural ratios: 20% IgG to neutralize toxins and pathogens, lactoferrin to starve bad bacteria of iron, and IGF-1 and EGF growth factors to rebuild the lining cell by cell. In research, it cut stress-induced gut permeability by about 80%.

Most Colostrum Is Collected Too Late. Ours Isn't.

The compounds that rebuild your gut peak on the very first day of milking, then drop 70%+ within 3-4 days. Most brands mix in later milkings to get more volume, so your scoop is a watered-down fraction. We collect on the first day only, from 650+ farms, and only after every calf is fed first. That's why every gummy delivers 20% IgG at full strength, the way nature made it.

  • Whole first-day colostrum, never later milkings
  • 300mg per gummy, 2-4 gummies a day
  • 650+ farms, calves always fed first
5ReasonA Routine You'll Keep

The Easiest Health Habit You've Ever Had

Your gut lining renews itself every few days, so it needs colostrum every day to rebuild stronger each time. Skip days and the repair stalls. That's the problem with powder. It clumps, tastes like a barn, and ends up forgotten in the pantry. Our gummies taste like a soft vanilla treat. No scooping, no stirring. Just 2-4 a day straight from the bag, so your gut never misses a day of repair.

The $186,000 Formula.

We spent over $186,000 and 14 months getting this formula right. First-day colostrum carries up to 4x more gut-rebuilding compounds than colostrum collected days later. We deliver it whole, with nothing removed, unlike a skimmed powder or a tiny capsule. And in a published human trial, bovine colostrum reduced gut leakiness. Every batch is third-party tested for purity, heavy metals and potency before it ships.

Frequently Asked Questions

Is this a laxative or a harsh cleanse?

No. Sunday Market colostrum gummies don't force anything out of your body. There's no rushing to the bathroom and no "detox" days. They work by feeding and strengthening your gut lining, the thin wall that decides what gets absorbed and what stays out. Colostrum gives that wall the building blocks it uses to rebuild: immunoglobulins (20% IgG), lactoferrin, natural growth factors and 400+ bioactive nutrients. As the lining gets stronger, digestion becomes calmer and more regular on its own, the gentle way your body was built to work.

Why a gummy instead of colostrum powder?

Because the best supplement is the one you actually take. Powder clumps, floats on top of your water, won't blend into coffee and has a strong farm taste, so most people quit within a few weeks. A gut lining rebuilds over weeks of steady use, so quitting means losing the benefit. Our gummies hold a full 300mg of whole first-day colostrum each, taste like soft vanilla (natural vanilla flavor, pectin instead of gelatin, only 3g of sugar), and come in a resealable bag you can take anywhere. Nothing to scoop, stir or rinse. That's why our customers stay consistent, and consistency is where the results come from.

How many do I take, and when?

Take 2-4 gummies a day. That's 600mg to 1,200mg of whole first-day colostrum. Lean toward 4 during sick season or when your gut needs extra support. They work best on an empty stomach, so a lot of our customers keep the bag next to the coffee maker and take them first thing. The routine takes about ten seconds, and because they taste like a treat, it's the one step of your day you won't skip.

How long until I notice a difference?

Most customers notice their digestion settling in the first 2-3 weeks: less bloating, calmer evenings, more predictable mornings. Energy usually follows in weeks 3-6 as your body absorbs more from the food you already eat. Skin, hair and nails are the last to show it, usually around months 2-3, because they grow on the nutrients a healthy gut delivers. That's exactly why we give you a full 90 days. Take 2-4 gummies a day, every day, and give your gut lining the time it needs to rebuild.

What makes Sunday Market colostrum different from other brands?

Three things. First, timing. Key bioactives in colostrum drop 70%+ in just 3-4 days, so we collect on the first day only, never later. Second, how it's collected. Our colostrum comes from 650+ farms, and the calves are always fed first. We only collect what's left after they've had their fill. Third, proof. Every batch is third-party tested for purity, heavy metals and potency, and every batch delivers 20% IgG. We spent over $186,000 and 14 months getting this formula right, so you get whole, full-strength colostrum in every 300mg gummy.

Will it upset my stomach when I first start?
Not likely. Colostrum is a gentle whole food your gut was made for, and most people feel nothing but good.

Colostrum is nature's first food, made to be gentle on a brand-new gut, which is why it's so easy on yours. Most people take their 2-4 gummies a day and just feel great. If your stomach is sensitive, take them with a meal.

Is it safe if I'm lactose intolerant or sensitive to dairy?
Yes for most people. Colostrum is naturally much lower in lactose than regular milk.

Colostrum is nature's first food, the first milk a cow makes after giving birth. It's richer in protein and fat than regular milk and carries much less lactose. Although it's a small amount, Sunday Market does contain lactose and milk proteins, so if you have a milk allergy, this is not for you. If you're lactose intolerant, it's always a good idea to check with your doctor before you start.

Can I take it with my medications or other supplements?
Colostrum is a whole food that's generally well tolerated. If you take prescription medication, check with your doctor first.

Sunday Market is a whole-food supplement made from real cow's colostrum, taken as 2-4 gummies a day. If you take prescription medication or have questions about your other supplements, show your doctor or pharmacist the Supplement Facts in the product images above. They can tell you how it fits with your routine.

Do the calves still get the colostrum they need?
Yes. We only collect colostrum on the first day after the calves are fed and full.

The calf always drinks first. Only after the calves have had their fill is the first-day colostrum collected, and that rule holds on every one of the 650+ US farms we source from, all with grass-fed, pasture-raised cows. It's the old-fashioned way of farming: take care of the animals first, and they take care of you. No newborn ever goes short so you can take colostrum. We wouldn't have it any other way.

What if it doesn't work for me?

Then you don't pay. Every order is backed by our 90-day money-back guarantee, and no return is required. Take 2-4 gummies a day for up to 90 days. If you don't feel the difference in your digestion, energy, skin or hair, contact our team and we'll refund every penny. Keep the bag, no questions asked. We can offer this because 20,000+ women already take Sunday Market every day, and we know what a stronger gut lining does for them. The only risk is waiting another season to feel like yourself again.
