10 Evidence-Backed Supplements for Muscle Soreness Relief and Recovery

1. L-Citrulline for Muscle Recovery

L-Citrulline helps reduce muscle soreness and supports faster recovery.1 This amino acid converts to L-arginine in the kidneys and raises nitric oxide levels more effectively than direct L-arginine.1 Better blood flow improves nutrient delivery and helps clear metabolic waste products like ammonia that drive fatigue.1

A 2010 randomized controlled trial with 41 men found that 8 grams of citrulline malate taken before resistance exercise enabled 53% more repetitions and delivered the 40% soreness reduction at 24–48 hours post-exercise.1 Many lifters use 6–8 grams of citrulline malate or 3–5 grams of pure L-citrulline about 60 minutes before training.

Bucked Up Pre-Workout provides 6,000 mg of citrulline malate (2:1 ratio) with Astragin to support absorption.1 Mother Bucker offers 4,000 mg of pure L-Citrulline with Nitrosigine and Hydroprime Glycerol for people who prefer a pure citrulline base with added pump and hydration support.1

2. Tart Cherry for Muscle Recovery

Tart cherry juice supplies natural compounds that help reduce inflammation and support muscle recovery.1 Research suggests 8–12 oz daily can help reduce muscle soreness and inflammation.1 Anthocyanins in tart cherries provide antioxidant support against exercise-induced oxidative stress.

Tart cherry juice also contains notable amounts of melatonin, and studies show that drinking it twice daily for one week increased total sleep time and sleep efficiency in healthy adults. Better sleep supports muscle recovery and growth hormone release.

Many people use about 240 ml of tart cherry juice twice daily, or a matching amount of concentrate mixed with water. This simple habit pairs well with L-Citrulline for a more complete recovery plan.

3. Curcumin for Muscle Recovery

Curcumin, the main active compound in turmeric, offers strong anti-inflammatory support that can limit exercise-induced muscle damage.1 A common approach is 500 mg daily with black pepper (piperine) to improve absorption.1 Piperine can significantly increase curcumin’s bioavailability.

Curcumin influences inflammatory pathways and can lower markers of muscle damage after hard training. Its antioxidant effects also help protect muscle tissue from free radical damage that slows recovery.

Taking curcumin with a fat source and piperine supports absorption. Many athletes pair curcumin with L-Citrulline so the anti-inflammatory support works alongside improved blood flow and nutrient delivery.

4. Omega-3 Fatty Acids for Muscle Recovery

Omega-3 fatty acids from fish oil help manage inflammation and support muscle recovery.1 Research often uses 2–3 g daily from fish oil to address chronic inflammation.1 EPA and DHA, the main omega-3s in fish oil, support inflammation resolution and muscle protein synthesis.

These fats help your body produce specialized pro-resolving mediators that actively wind down inflammation. This resolution phase supports proper muscle adaptation and recovery after training.

Look for fish oil that provides at least 1,000 mg combined EPA and DHA per serving. Taking omega-3s with meals can improve absorption and reduce digestive discomfort.

5. Whey Protein for Muscle Recovery

Whey protein supplies essential amino acids that drive muscle protein synthesis and repair.1 Its fast digestion makes it a solid choice right after training when muscles are primed for nutrients.

Many lifters aim for 20–25 g of whey protein within about 30 minutes after exercise to support muscle protein synthesis.1 Whey’s high leucine content helps trigger the muscle-building process.

Whey protein pairs well with L-Citrulline. Whey provides the raw materials for repair, while L-Citrulline supports blood flow so those amino acids reach muscle tissue efficiently.

6. Branched-Chain Amino Acids (BCAAs) for Muscle Recovery

BCAAs (leucine, isoleucine, and valine) can help limit exercise-induced muscle damage and support recovery when taken around workouts.1 Some research suggests citrulline malate can improve branched-chain amino acid utilization during exercise, which points to a complementary relationship.

Typical intake ranges from 10–15 g of BCAAs, often in a 2:1:1 ratio that favors leucine.1 You can use them before, during, or after training to support muscle protein synthesis and reduce breakdown.

BCAAs can be especially helpful when training fasted or during long sessions where muscle breakdown may outpace synthesis.

7. Magnesium for Muscle Recovery

Magnesium supports muscle function, protein synthesis, and energy metabolism.1 Intense training and heavy sweating can deplete magnesium, so many athletes benefit from topping up their intake.

Many people use 200–400 mg of magnesium daily. This range works best with highly bioavailable forms such as magnesium glycinate or citrate, which your body can absorb and use more effectively. When magnesium levels stay adequate, muscles contract and relax properly and may cramp less often.

Magnesium also supports sleep quality, which plays a major role in recovery and growth hormone release. Taking magnesium in the evening can support deeper sleep and overnight muscle repair.

8. Creatine for Muscle Recovery

Creatine monohydrate supports recovery by helping regenerate ATP stores quickly and by limiting exercise-induced muscle damage.1 Many people follow a loading phase of 20 g daily for 5 days, then move to 3–5 g daily for maintenance.

Research links creatine use with lower markers of muscle damage and inflammation after intense exercise. Faster ATP regeneration also supports higher training volume and better recovery between sets.

Creatine often pairs well with L-Citrulline. Improved blood flow from L-Citrulline can support creatine delivery into muscle cells.

9. Beta-Alanine for Muscle Recovery

Beta-alanine helps delay muscle fatigue by buffering acid buildup during high-intensity efforts.1 Studies associate this amino acid with better endurance and high-intensity performance, which can support recovery between sessions.

Effective intake usually falls between 3–5 g daily, often split into smaller servings to limit the tingling sensation many users notice. Several weeks of consistent use are needed to raise muscle carnosine levels.

Beta-alanine works alongside L-Citrulline by targeting a different part of fatigue. Beta-alanine buffers acid buildup, while L-Citrulline supports nutrient delivery and waste removal.

10. Vitamin D for Muscle Recovery

Vitamin D supports muscle function, protein synthesis, and immune health.1 Many athletes, especially those training indoors or living in northern regions, have lower-than-ideal vitamin D levels.

Many protocols use 1,000–4,000 IU daily, with higher intakes sometimes needed to correct deficiency. Vitamin D3 (cholecalciferol) is often preferred because it tends to have better bioavailability than D2.

Adequate vitamin D supports testosterone production, muscle strength, and recovery from exercise-related inflammation. Regular blood work helps dial in the right dose for each person.

Why L-Citrulline Stands Out for DOMS and Muscle Soreness Relief

L-Citrulline offers recovery support through its metabolic pathway and several mechanisms of action. Unlike L-arginine, which intestinal enzymes can degrade, L-Citrulline bypasses that step and converts to L-arginine in the kidneys. This process supports sustained nitric oxide production and better blood flow, which helps clear waste products that drive soreness.

Research also shows L-Citrulline supplementation improved physical performance in cyclists by 12% and reduced post-exercise fatigue. This metabolic advantage, which avoids the intestinal breakdown that limits L-arginine, helps explain why L-Citrulline often outperforms direct arginine in studies.

Bucked Up offers several L-Citrulline options. Mother Bucker provides 4,000 mg of pure L-Citrulline with Nitrosigine, while Woke AF includes 6,000 mg of citrulline malate for users who prefer a high-stimulant pre-workout. Bucked Up promotes science-backed ingredients, including citrulline malate and pure L-Citrulline. Find your preferred L-Citrulline formula at buckedup.com.

Smart Stacks and Timing for Post-Workout Muscle Soreness Relief

Strategic supplement stacking can amplify recovery benefits compared with using single ingredients alone. A popular soreness stack combines L-Citrulline with tart cherry and omega-3 fatty acids. L-Citrulline supports ammonia clearance, reduces lactic acid buildup, and improves nutrient delivery, while tart cherry and omega-3s address inflammation through different pathways.

Many athletes take 6–8 g of L-Citrulline about 60 minutes before training, then use tart cherry juice and omega-3s after the workout. Citrulline malate combines L-Citrulline with DL-malate, which supports energy production during exercise, so it fits well as a pre-workout choice.

Bucked Up Non-Stimulant Pre-Workout provides 6,000 mg of citrulline malate for evening or caffeine-sensitive users. The standard Bucked Up Pre-Workout offers the same citrulline dose with 200 mg caffeine for daytime training. Both formulas include beta-alanine for added acid buffering and broader recovery support.

Recovery Supplements for Athletes Over 40

Athletes over 40 often face slower recovery because of lower hormone levels, reduced protein synthesis, and higher baseline inflammation. L-Citrulline remains a practical option in this group because research supports its safety at commonly used doses. Studies have used 10–15 g per day of L-Citrulline with good tolerance and few reported side effects.

People with low blood pressure should talk with a healthcare provider before using L-Citrulline, since its vasodilating effects can sometimes cause dizziness.1 Anyone scheduled for surgery should stop use at least two weeks beforehand. Doses above 10 g can cause mild gastrointestinal discomfort for some, so many users stay in the 6–8 g range.1

This focus on transparent, evidence-based formulation can make Bucked Up products appealing for athletes who want reliable recovery support. Find the right L-Citrulline option to support your performance and recovery.
