Here's the story...

From our customers

★★★★★
I'm 35 weeks pregnant and my ferritin levels have been pretty low the past couple of months. Not crazy low (as I understand it's natural for iron stores to drop during pregnancy), but my doc recommended I start an iron supplement which I very much did not want to do since constipation has already been a real... She briefly mentioned trying a beef liver supplement and I immediately thought of you guys, maybe partly because of being brainwashed by your ads on your podcasts, but also because you guys are just awesome.

You guys helped me get my period back 3 years ago, and I now have a beautiful daughter, so I love you all and will support anything you do. But as a brand you guys are so reliable and credible. I rarely trust supplements, but I love the fact that this one is as real and raw as it gets and owned by girls who actually care about what goes into the body and female health overall.

I noticed a massive difference in my hair and nails on beef liver especially when I STOPPED it for a month. I’m still battling with some acne and hoping that the job switch, actual 8 hours of sleep, + consistency with this supplement will get my skin looking right.

★★★★★
I saw Abby Grimm post about it and have been contemplating starting back taking beef liver for a while. I am currently 25 weeks pregnant and want to make sure I am giving the baby and myself the most nutritious things I can. I have been loving both products so much! My energy feels so much better and my skin and hair feel healthier.

the desiccated oyster drew me in— especially after one of you shared that after consistently taking it you noticed a positive change in your cycle and especially more Cervical mucus, which is something I struggle with. So the main reason I chose the Oyster capsules was in hopes of supporting my cycle and hormone balance!

We're fertility experts that run a practice together.

Years of birth control, over exercising, under-eating and pursuing health and performance in all the wrong ways left us – Ashley, Mishi and Dani – extremely depleted.

On our individual journeys to restore our fertility and bring our entire bodies back to health we discovered that our existing food sources were heavily depleted no matter how hard we tried to eat enough proteins and vegetables.

We needed a therapeutic dose of nutrients. This is where we discovered the value of organ meats.

It turns out that beef liver and oyster as a foundational nutrient for overall health.

We started recommending it to all of our clients and the results have been INCREDIBLE.

The challenge? Sourcing, preparing and even just eating liver and oysters regularly was honestly pretty enough. We needed a solution.

So now there’s Jool Wellness.

Our capsules are the daily solution you need for your longevity, health, energy and more.

Ok cool... what's so good about beef liver and oysters?

We're glad you asked...

Beef liver has approximately 8–10x more vitamin A than a typical multi

and importantly, it’s the preformed, active retinol form, not beta-carotene.
This supports clear, healthy skin and a smooth complexion by promoting cell turnover and reducing inflammation.

Koury, J. M., & Moser, P. B. (1995). "Vitamin A and liver function: a review of the roles and significance of retinol and retinoids in liver function and metabolism."

8x more B12

The B12 from liver and oyster is natural methylcobalamin and adenosylcobalamin — the active forms — while multis vary (some use cheaper cyanocobalamin).
All this b12 boosts energy levels and reduces fatigue by supporting red blood cell production and helping convert food into usable energy.

📖 Reference: NIH Office of Dietary Supplements: Iron, Vitamin B12: Iron and B12

REAL Iron Content That's Better Absorbed from Liver and Oyster

Heme iron is ~3× more usable than iron from a multi (which doesn't contain any heme iron) because it's real and wasn't made in a lab.
Iron from liver and oyster supports healthy energy and focus by helping deliver oxygen to your brain and muscles—key for athletes, and anyone looking to resolve fatigue.

📖 Reference: Reference Hallberg L, Hulthén L. (2000). "Prediction of dietary iron absorption: an algorithm for calculating absorption and bioavailability of dietary iron."

Just as much omega-3 as fish oil

Oysters offer about the same omega-3 as a higher-dose fish oil capsule, depending on the brand. Not bad for a food!
Supports brain health, mood, and inflammation with easily absorbed omega-3s (EPA & DHA) naturally found in oysters.

Unlike plant-based omega-3s (like ALA from flax), the omega-3s in oysters are already in the forms your body needs—no conversion required, making them especially effective for cognitive, heart, and hormone support.

Ultimate Zinc Source

Fresh oysters are the highest natural food source of zinc with ~74 mg of useable zinc per serving – well above daily needs.

Natural zinc strengthens immune function, promotes hormone function and supports clear skin by regulating inflammation and promoting tissue repair.

As seen in...

I love that these supplements are from whole food sources.Youguys also explained so well why beef liver and oyster capsules are beneficial. I had my first ovulation and period after just a few weeks taking them! Maybe just a coincidence with the other changes that had been made prior but I have no doubt that they definitely helped!

- Amber, customer

I have heard before that zinc was good for female health as well as eating liver meats, but I never really dug too much into it. It wasn’t until I discovered you all that I learned a lot more about it! I’ve seen naturopaths and been on a million different supplements, so adding in more was not appealing to me. Then I learned how taking beef liver and oyster could replace a lot of things I was on and I was sold! I’ve only been taking them for a little over a month now, and I will say that my nails have never been this strong. Not sure if it’s related, but can’t think of what else it would be!
