Why Beef & Tallow?
-
100% Grass-Fed Beef
Packed with essential amino acids to repair muscle, boost hormones, and support natural energy. Unlike soy or whey isolates, grass-fed beef provides complete, bioavailable protein your body actually recognizes and uses.
-
Rendered Beef Tallow
A clean fat source that fuels endurance, brain power, and fat-burning metabolism. No seed oils. No inflammatory vegetable fats. Just pure, stable animal fat that humans have thrived on for thousands of years.
-
Zero Sugar & Carbs
Keeps insulin low, supports ketosis, and prevents energy crashes. Unlike sugar-loaded bars that spike and crash your blood sugar, NuProtein delivers steady, sustained power throughout your day.
-
Lab Tested & EHO Approved
Verified for safety, purity, and quality with official EHO registration. Every batch is tested before it reaches you. No sketchy ingredients, no corners cut - just legitimate, certified nutrition you can trust.
Born from Belief. Built by Lions.
NuProtein was created with one purpose - to fuel the human body with real strength.
While others use fillers and seed oils, we chose nature's original performance fuel: beef and tallow. Lab-tested, EHO approved, made in Britain.
Every bar is a commitment to strength. For the focused. The disciplined. The unstoppable.
Frequently Asked Questions
What do they taste like?
Rich, savoury, and satisfying. Original has a pure beef flavour with a hint of salt. Blueberry and Strawberry add a subtle natural fruit taste without sweetness - they're not like traditional protein bars. This is real food, not candy disguised as nutrition.
What's the texture like?
Dense and satisfying, not dry or chewy like jerky. The tallow gives a smooth, rich mouthfeel. If stored at room temperature, they're softer; if refrigerated, they're firmer. Both are perfectly fine - it's personal preference.
What are the ingredients?
- Original: 100% Grass-Fed Beef, Rendered Beef Tallow, Himalayan Salt
- Blueberry: 100% Grass-Fed Beef, Rendered Beef Tallow, Blueberry Powder, Himalayan Salt
- Strawberry: 100% Grass-Fed Beef, Rendered Beef Tallow, Strawberry Powder, Himalayan Salt
That's it. No seed oils, no preservatives, no fillers, no junk.
How much protein is in each bar?
Each 60g bar contains approximately 25g of complete animal protein - all the essential amino acids your body needs for muscle repair, hormone production, and sustained energy.
Are there any additives or preservatives?
None. Only natural ingredients: beef, tallow, salt, and fruit powder (for flavoured bars). We don't use preservatives, seed oils, or synthetic additives. Just real food.
Are NuProtein bars keto or carnivore friendly?
Absolutely. Original has zero carbs. Blueberry and Strawberry have 1g of carbs from natural fruit powder - still firmly keto-friendly. All bars are 100% carnivore-compatible with zero sugar.
Are they halal?
Yes. All beef and tallow are sourced from certified halal suppliers. Every ingredient meets halal standards.
Are they suitable for athletes / Can I use these for workout fuel?
Yes. The combination of complete protein (25g) and clean fat (30-34g) provides sustained energy without crashes. Perfect for pre-workout fuel (1-2 hours before), post-workout recovery (within 30 minutes), or as a meal replacement when you're on the move.
How long do they last?
Each bar has a minimum shelf life of 6 months when stored properly. Check the best-before date on your package.
Do they need refrigeration?
No. You can store them at room temperature in a cool, dry place. Refrigeration is optional - it extends freshness and firms up the texture if you prefer a firmer bar.
What if the bars become soft?
If your bars soften (usually from warmth), just pop them in the fridge for 5 minutes to firm them back up. Texture may change with temperature, but quality and nutrition remain the same.
Can I mix flavours in a pack?
Currently, each multi-pack contains a single flavour. If you'd like to mix flavours, simply order different flavour packs separately. We're exploring mix-and-match options for the future.
How long does delivery take?
We ship within 1-2 business days of your order. Standard UK delivery takes 3-5 working days. Express delivery (1-2 working days) is available at checkout.
You'll receive tracking information via email once your order ships.
Is NuProtein lab-tested and approved?
Yes. Every batch is lab-tested for purity and safety. We're registered and approved by the Environmental Health Authority (EHO). Quality and safety are non-negotiable.
