Frequently Asked Questions

  • What is the Jacob Bar?

    A protein bar made with real food.

    Sweetened with organic honey & dates, with grass-fed beef tallow & almond butter for fat.

    No seed oils. No artificial sweeteners. No natural flavors. No gums.

  • What makes Jacob "The World’s Cleanest Protein Bar”?

    Two things:

    1. What we put in. Grass-fed protein. Organic honey and dates. Grass-fed beef tallow. Real cocoa, real vanilla, real berry powders. Every ingredient has a purpose.
    2. What we leave out. No seed oils. No artificial or non-nutritive sweeteners. No "natural" flavors. No gums. No emulsifiers. No preservatives.

  • What kind of protein do you use?

    • A grass-fed, animal-based blend: whey protein isolate, milk protein isolate, and collagen.
    • Animal proteins absorb more efficiently than plant proteins.
    • Clean, highly absorbable fuel to support your muscle growth and function, alongside collagen to promote skin, hair, and joint health.

  • Why do you use beef tallow?

    • Nutrient-dense fats keep you satiated and energized.
    • Beef tallow is packed with important fat soluble vitamins A, D, E, and K, along with choline and CLA to support brain function, anti-inflammation, and overall energy.

  • Why is there sugar in your bar?

    • Organic honey and dates are the only sugars in our bar. There are ZERO artificial, refined, or processed sugars.
    • Although it is a healthier, more natural option, honey is still considered an "added sugar" to the FDA.
    • Most protein bars hit a low sugar number by using sucralose, stevia, monk fruit, or sugar alcohols.
    • We use organic honey and dates. Your body knows what to do with these. It does not know what to do with artificial sweeteners.

  • What are "natural" flavors and why do you avoid them?

    • We don’t use “natural” flavors, which in our opinion, is anything but natural. While food manufacturers must list all of the ingredients on a food label, "natural” flavor manufacturers do not have to disclose their ingredients.
    • They can add synthetic solvents, preservatives, and other additives to create flavor compounds that trick your brain and taste buds into craving a flavor more than it should.
    • We opt for transparent flavoring, using pure extracts and powders from whole food ingredients.
