“It’s now a non-negotiable in my gym bag.”. Oliver W.

That burn in your legs at the end of a sled push. The moment your arms go heavy in a rowing station. The wall you hit in the final 2km of a run. That’s hydrogen ion accumulation, and ENDURE+ is built to push it back.

Using Aquamin marine minerals: one of the most bioavailable forms of Magnesium and Calcium available: alongside Bioperine for enhanced absorption and Ginger for anti-inflammatory support, ENDURE+ helps you hold higher intensity for longer, reduce mid-session cramp, and recover faster between efforts.

No tingling. No nausea. No side effects. Just more of you, in the session that matters.

  • Push Through the Burn: ENDURE+ buffers the hydrogen ion accumulation that causes the burning sensation during high-intensity exercise, helping you maintain pace through Hyrox stations, functional fitness sets, and endurance efforts without blowing up.
  • No Tingling. No Nausea. No Waiting: Traditional lactic acid buffers like beta-alanine take 4–10 weeks to work and cause skin tingling. Sodium bicarbonate loading causes GI distress. ENDURE+ uses Aquamin marine minerals to work within 48–72 hours: with no side effects.
  • Built for Daily Use: Take 8 capsules per day, split morning and evening. The longer you use it, the greater the accumulated benefit. Think of it as a performance vitamin, not a pre-workout.
  • Better Absorption by Design: Bioperine (black pepper extract) enhances the bioavailability of all active ingredients, ensuring every capsule delivers its full effect rather than passing through unused.
  • Recover Faster: Aquamin Calcium (400mg) and Magnesium (189mg) support muscle function and post-session recovery. Selenium (100% RI), Chromium (100% RI), and Ginger Extract reduce inflammation and oxidative stress: so your body is ready to go again sooner.

Description

ENDURE+. Why Your Muscles Burn, and How to Fight Back

Here’s the science in plain English.

When you push hard: a sled push, a rowing sprint, a heavy set of wall balls: your muscles generate energy anaerobically. This process produces hydrogen ions (H⁺) as a byproduct. As these ions accumulate, your muscle pH drops from its resting level of around 7.1 toward 6.4. That falling pH is what you feel as the burn. It’s what forces you to slow down, take a step back, or stop entirely.

Buffering that drop in pH is how you push the wall further back.

The standard approach is beta-alanine: a popular supplement that builds muscle carnosine (an intracellular buffer) over 4–10 weeks of daily loading. The problem: it takes months to work, causes skin tingling in most users, and provides only intracellular (inside the muscle) buffering.

Sodium bicarbonate loading works faster, but frequently causes nausea and GI distress that makes it impractical for race day use.

ENDURE+ takes a different approach.

Aquamin marine-sourced Magnesium and Calcium provide an extracellular buffering action, working in the bloodstream and around the muscle rather than inside the cell. This is why users notice the difference within 48–72 hours rather than waiting weeks. And because Bioperine (black pepper extract) is included in the formula, the active ingredients are absorbed significantly more efficiently than they would be without it.

Ginger Extract (200mg) adds anti-inflammatory support, reducing the oxidative damage caused by high-intensity training. Selenium and Chromium are included at 100% of daily reference intake, supporting antioxidant function and glucose metabolism respectively.

The result: a supplement that helps you hold higher intensity for longer, experience less mid-session cramp, recover faster between efforts, and feel less of the delayed onset soreness that follows a hard session.

Trusted by Hyrox athletes, functional fitness competitors, endurance runners, cyclists, rugby players, and firefighters competing at national level. This is what your body can do when the burn isn’t the limit anymore.

Suitable for: Hyrox, CrossFit, functional fitness, endurance running, cycling, team sports, any high-intensity training discipline.
Not suitable for: Under 18s, pregnant or breastfeeding women, those with kidney conditions (seek medical advice first).

Stack with: Hydro Fuel for pre-session energy, Hydro OG during or after for recovery hydration. The full LyfeLinez performance stack.

Why ENDURE+ Works Better Than Beta-Alanine

  ENDURE+ Beta-Alanine
Time to work 48–72 hours 4–10 weeks
Side effects None Skin tingling
GI distress None Possible
Daily dose 8 capsules 3–6g powder
Absorption Enhanced (with Bioperine) Standard
Buffering action Extracellular Intracellular

Both approaches have scientific merit. But for athletes who need results now, not after a two-month loading phase. ENDURE+ is the smarter starting point.

How to Use ENDURE+

Take 8 capsules per day with water, split into two servings:

  • 4 capsules in the morning
  • 4 capsules in the evening

For maximum benefit, begin 3–7 days before a heavy training block or race. Continue daily throughout your training cycle.

ENDURE+ is a cumulative supplement: the longer you use it consistently, the stronger the buffering effect. Most users notice the difference within the first week, with significant results by weeks 3–4.

Not suitable for under 18s, pregnant or breastfeeding women, or those with a diagnosed kidney condition. Consult a healthcare professional before use if you are taking medication.

★★★★★ “It’s now a non-negotiable in my gym bag.” — Oliver W.
