These beef sticks are some of the healthiest, best-tasting snacks on the market. They're not cheap, but they are good value for money. Their compact size makes them easy to pack in you car, backpack or purse for a healthy, protein snack when needed. The fat content is minimal, but certainly adds to the overall flavor. The only issue is the packaging. We've been getting these regularly for more than a year, and nearly every time the "Peel Here To Open" end of the stick is actually sealed. It's like the machine is missing the mark, so you have to use scissors and that makes them way less convenient. Seems like a simple fix.

Reliable product made with care

quality has been consistently excellent every single time. It’s reliable, tastes great, and you can tell it’s made with care. What really stands out is how it makes me feel afterward. Even after working a 12-hour overtime shift, I don’t feel as exhausted. It genuinely helps me keep my energy up. Highly recommend if you’re looking for something dependable and effective. I’ll definitely keep ordering.

Look nice.

These were really nice for canned oysters, way better than what we can get in the stores in our area. Perfect for milk based oyster soup! the ratio is one can of cream of mushroom, one can full of milk, one can of oysters. Add butter, salt, pepper, and bring to a boil.

Does the job

Tastes like boiled oysters, so it has that nailed down. I use it in my shrimp ramen noodles sometimes, sometimes I use it to flavor garnish dishes. Best price I could find, but apparently it is a specialty product.

Unparalleled source of heme iron.

This stuff is medicine if your are anemic or have low serum iron. Elemental iron from veggies or pills must be prepared by your body to carry oxygen in hemoglobin. Not so with iron from animals and oysters are unparalleled in iron content. Even if you don't find them delicious you will find them efficacious.
