Beta Alanine, 100% and nothing else. 300g, 100 servings, 3g per scoop. 

Beta alanine helps buffer lactic acid and delay muscle fatigue during high-intensity exercise. It builds up over time, so take it daily and give it 4 weeks before you judge it.

Built for

  • The 1 to 4 minute efforts where lactic acid does the damage
  • Sled push, ski erg, wall balls, and the back half of a Hyrox
  • Anyone already taking creatine daily who wants the endurance side covered

How to use

  • 100 servings per pouch, 3g per level scoop
  • 6g daily, split into 2 servings: one morning, one evening
  • Mix one scoop with 200 to 400ml cold water, shake well and drink
  • Take with a meal or before exercise
  • Unflavoured, so it mixes into anything
  • Suitable for vegetarians and vegans. Allergen free.

About the tingling

Beta alanine can cause a temporary harmless tingling sensation (paraesthesia). It's normal and subsides within 30 to 60 minutes. Splitting your 6g across the day keeps it manageable.

Beta alanine is the rate-limiting building block for carnosine, the compound your muscles use to buffer acid during hard efforts:

  • Lactic Buffering:

    Raises muscle carnosine, the intracellular buffer that soaks up hydrogen ions during hard efforts

  • Muscular Endurance:

    Strongest effect on efforts lasting roughly 30 seconds to 10 minutes, where acidosis limits output

  • Stacks With Creatine:

    Different energy system, same daily habit. Modest additive benefit when both are taken at full dose

Interval is manufactured in a facility that is certified by GMP, FDA, ISO 22000 & ISO 9001:2015.

Usage: Mix one level scoop (approximately 3g) with 200 - 400ml of cold water, shake well and consume. Consume 1-2 servings daily, preferable with a meal of before exercise.

Split dosage across the day to reduce tingle effect (paraesthesia).

Storage: Keep sealed and store in a cool dry place, away from direct sunlighht.

REACH OUT

Start with 3g daily for 5 days, then take 6g daily. Some people choose to "load" with 20g per day (split into 4 doses) for 5-7 days to saturate muscles faster, but it's not necessary - the daily dose will get you there in 3-4 weeks.

Timing doesn't matter much. Take it whenever fits your routine - pre-workout, post-workout, or with breakfast. Consistency matters more than timing.

Take it with carbohydrates (juice, smoothie, or a meal) to slightly improve absorption, but it works fine on its own too. Just avoid taking it with caffeine immediately before training as it may reduce effectiveness.

There's insufficient research on creatine during pregnancy and breastfeeding, so we recommend avoiding it during these periods. Speak with your doctor for more information.

Creatine draws water into muscle cells, which can add 1-2kg initially. This is intramuscular water (inside the muscle), not bloating. It's part of how creatine works and contributes to the fuller, stronger muscle feeling.

No. Creatine can be taken continuously without cycling. Your body doesn't build tolerance, and long-term studies (up to 21 months) show it's safe for ongoing use.

Most people notice strength and performance improvements within 1-2 weeks. If you load (20g/day for 5-7 days), you'll see results faster - typically within the first week.
