Ten star quality and hands down the best I've ever had
Flavor Name: Venison Sticks - Original
I had a health practitioner suggest I increase protein intake and add in some game meats (venison, bison, elk) along with beef. I found Paleo Valley venison and beef sticks as a great solution to add these to my diet without a big bite in my budget. Paleo Valley provides several beef sticks that are all tasty and will appeal to a variety of consumer preferences though my personal favorite is the venison. All their sources are grass fed and finished, pasture raised and finished. You can instantly taste the difference in quality with your first bite. The sticks are firm and moist, nicely flavored and are simple to carry around as a quick snack or extra protein boost. I found I have less interest in sugary or carb-filled snacks by eating a quality protein source. Many other brands I've tried are hard, dry, heavily spiced and don't really taste natural. Not so with Paleo Valley. As a company, I found them to be very health conscious and have other supplements available, along with really useful educational tips for a healthier lifestyle. I think it's important to leave good reviews when I find something that's exceptional quality and Paleo Valley fits that bill.

BEST GLUTEN FREE BEEF STICKS!
Flavor Name: Beef Sticks - Original
I have bought these mulitple times and now have decided to become a monthly subscriber. I love the fact of the "natural" ingredients, these are truly GLUTEN FREE with no hidden ingredients. The taste is amazing and has the perfect amount of spices, not to much but by NO means bland either. They are always fresh and last a long time. They are never dry, not one single time.

Half a bad batch?
Flavor Name: Venison Sticks - Original
Unsure if I got a bad batch, ill explain why I gave it a 3.
First four I had had the consistency of a banana and just tasted extremely off. It was oily, greasy, and the texture was just not something I ever experienced, and ive had venison/beef sticks before. It was pretty disgusting
I brought them to work to ensure they didnt go to waste and kept one
The one I had was perfect flavor, texture, non greasy and exactly what I had expected. Checked with the coworkers I shared them with and theirs were fine.
It leads me to believe maybe it was a bad batch? If they were all like the first few id say 0 stars, if they were all like the last id say 5

Good tasting, healthy snack that is high in protein and low in fat. But can be a pain to open.
Flavor Name: Beef Sticks - Original
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.
