1. Nuun Sport Electrolyte Tablets – Best Overall

Nuun Sport is the most popular electrolyte supplement among hikers and backpackers for good reason — the lightweight, portable tubes fit easily into any pack and deliver five essential electrolytes with minimal sugar.

Each effervescent tablet dissolves in 16 ounces of water and provides 300mg sodium, 150mg potassium, 40mg chloride, 25mg magnesium, and 13mg calcium. Dehydration and electrolyte imbalance are the most common performance-limiting issues on the trail, and many hikers unknowingly develop hyponatremia (dangerously low sodium) by drinking large amounts of plain water during hot-weather hikes without replacing electrolytes lost through sweat. Nuun’s compact tube design weighs almost nothing in your pack, and multiple flavor options prevent taste fatigue on multi-day trips. Vegan, non-GMO, and gluten-free.

• Pros:
• Ultralight tube design adds virtually no pack weight
• Balanced electrolyte profile prevents hyponatremia during long hikes
• Only 1 gram of sugar per tablet — no energy crashes on the trail

• Cons:
• Lower sodium than some heavy-duty rehydration solutions
• Needs 2-3 minutes to fully dissolve in cold stream water

Best for: Day hikers and backpackers who need lightweight, effective hydration support on every trip

2. PurePremium Beet Root Capsules 14-in-1 – Best for Trail Endurance

This comprehensive 14-in-1 beet root formula boosts nitric oxide production for improved oxygen efficiency on steep climbs and high-altitude trails where every breath counts.

PurePremium combines concentrated beetroot powder with hawthorn berry, garlic, green tea extract, CoQ10, and grapeseed extract in a single capsule. Dietary nitrates from beet root reduce the oxygen cost of physical exertion, which is particularly valuable when hiking at elevation where oxygen is already limited. The addition of hawthorn berry and garlic supports cardiovascular function during sustained uphill efforts. The capsule format is trail-friendly — no measuring, mixing, or refrigeration required. Made in a GMP-certified USA facility.

• Pros:
• 14-in-1 formula covers endurance, circulation, and antioxidant support
• Especially valuable for high-altitude hiking where oxygen delivery matters most
• Shelf-stable capsules require no special storage on the trail

• Cons:
• Multi-ingredient blend makes individual dosing less transparent
• Best results come from consistent daily use, not just day-of supplementation

Best for: Hikers tackling high-altitude trails, long ascents, or multi-day treks where sustained endurance is critical

3. Nordic Naturals Ultimate Omega – Best for Joint Health

With millions of steps over uneven terrain, hiking puts tremendous stress on knees, ankles, and hips — Nordic Naturals delivers the anti-inflammatory omega-3 dosing that helps keep hikers on the trail instead of reaching for ibuprofen.

Each two-softgel serving provides 1,280mg of combined EPA and DHA in highly absorbable triglyceride form. Fish oil’s anti-inflammatory properties have made it a natural alternative to the ibuprofen (nicknamed “Vitamin I” on the trail) that many hikers over-rely on. Long-term NSAID use damages the stomach lining and impairs muscle recovery — problems omega-3 supplementation avoids while providing comparable anti-inflammatory benefits. Nordic Naturals is Friend of the Sea certified, non-GMO verified, and tested for 400+ environmental contaminants. Lemon flavoring minimizes fish burps on the trail.

• Pros:
• Natural anti-inflammatory alternative to ibuprofen overuse
• Triglyceride form provides superior absorption over ethyl ester alternatives
• Supports joint, heart, and brain health simultaneously

• Cons:
• Softgels can soften in extreme heat on summer hikes
• Premium price compared to budget fish oil options

Best for: Hikers prone to knee pain, joint stiffness, or those wanting to reduce reliance on ibuprofen on the trail

4. Snap Supplements Nitric Oxide Beet Root Gummies – Best Trail-Friendly Snack

These beet root gummies double as a tasty trail snack while delivering nitric oxide support for better circulation and endurance during long hiking days.

Snap Supplements combines organic beet root extract with pomegranate powder in a chewable gummy format that requires no water for consumption — a real advantage when trail water sources are limited or you’re on the move. The nitric oxide boosting properties of beet root improve oxygen utilization during sustained uphill effort, while pomegranate’s polyphenols provide additional antioxidant protection against the oxidative stress of prolonged outdoor exercise. No artificial colors or flavors.

• Pros:
• Chewable format requires no water — perfect for on-the-go trail use
• Pleasant taste makes compliance easy during multi-day hikes
• Pomegranate adds antioxidant protection for extended outdoor exposure

• Cons:

5. Thorne Magnesium Bisglycinate – Best for Cramp Prevention

No products found.

Magnesium is the single most important mineral for hikers to supplement, and Thorne’s NSF Certified bisglycinate form prevents the leg cramps, muscle spasms, and poor sleep that plague long-distance trekkers.

Hikers lose significant magnesium through sweat, and trail diets heavy on processed carbohydrates rarely replace what’s lost. Low magnesium leads to the muscle cramps and spasms that many hikers attribute to general fatigue but are actually addressable through proper supplementation. Thorne’s bisglycinate form provides the highest bioavailability of any magnesium supplement without the digestive issues (read: emergency bathroom stops on the trail) that plague magnesium citrate and oxide. NSF Certified for Sport ensures purity and potency.

• Pros:
• NSF Certified for Sport with guaranteed purity and potency
• Bisglycinate form is gentle on the stomach — critical for trail comfort
• Supports both daytime muscle function and nighttime recovery sleep

• Cons:
• Premium pricing compared to generic magnesium
• May need 2-3 capsules daily for optimal athletic dosing

Best for: Long-distance hikers and backpackers who experience leg cramps, muscle tightness, or poor sleep on the trail

6. Garden of Life Sport Organic Multivitamin – Best Multivitamin

No products found.

When trail meals consist primarily of energy bars, instant noodles, and trail mix, a comprehensive whole-food multivitamin fills the micronutrient gaps that sustained exertion and limited food variety create.

Garden of Life Sport provides 30+ vitamins and minerals from organic whole-food sources, including the B vitamins critical for energy metabolism, iron for oxygen transport, zinc for immune function, and vitamin D for bone health. The formula includes a 500mg organic turmeric blend for anti-inflammatory support and a probiotic blend to maintain gut health — a common issue on extended hiking trips where food quality and hygiene conditions decline. NSF Certified for Sport and USDA Organic.

• Pros:
• Whole-food sourced vitamins and minerals for better absorption
• Includes probiotics for trail gut health support
• NSF Certified for Sport and USDA Organic dual certification

• Cons:
• 4 tablets per serving adds to daily pill count on the trail

Best for: Thru-hikers and multi-day backpackers whose trail diets lack nutritional variety

7. Iron Brothers Nitric Oxide Supplement – Best for Altitude

Iron Brothers’ nitric oxide formula enhances blood flow and oxygen delivery through L-arginine, L-citrulline, and beet root extract — a combination that proves especially valuable on high-altitude trails where thin air limits performance.

At elevation, your body’s ability to deliver oxygen to working muscles is compromised. Nitric oxide supplementation supports vasodilation, improving blood flow and potentially mitigating some of the fatigue and reduced performance associated with altitude hiking. L-citrulline has been specifically studied for reducing perceived exertion during sustained physical activity, and the stimulant-free formula means no unwanted heart rate spikes on exposed alpine terrain. The capsule format packs easily into any first aid or supplement kit.

• Pros:
• Stimulant-free formula safe for high-altitude exertion
• Multiple nitric oxide pathway support for enhanced oxygen delivery
• Capsule format is lightweight and trail-ready

• Cons:
• Not a substitute for proper acclimatization at altitude
• Clinical evidence for altitude-specific benefits is limited

Best for: Hikers who frequently trek above 8,000 feet or in mountain environments where oxygen delivery is a limiting factor

8. Effective Nutra Creatine Gummies – Best for Multi-Day Recovery

Creatine helps hikers recover between consecutive hard days on the trail, reducing muscle damage and supporting the energy production needed to keep moving day after day.

Effective Nutra’s vegan creatine gummies provide 1 gram per gummy in a sugar-free, portable format. While creatine is most associated with gym-based training, its benefits extend to any sustained physical activity: improved cellular energy production, reduced muscle damage markers, and faster recovery between bouts of exercise. For multi-day hikers covering 15-25 miles daily, the cumulative recovery benefit of consistent creatine supplementation can mean the difference between fresh legs and forced rest days. GMP-certified and third-party tested.

• Pros:
• Sugar-free gummy format is easy to take on the trail without water
• Supports recovery between consecutive high-mileage hiking days
• Vegan-friendly for plant-based hikers

• Cons:
• Need 3-5 gummies daily for effective dose — adds to pack weight on long trips
• Less studied specifically for hiking compared to gym-based exercise

Best for: Multi-day hikers and thru-hikers who need to recover quickly between consecutive days on the trail

9. NatureBell Vitamin D3 + K2 – Best for Bone Support

Despite spending time outdoors, many hikers are still vitamin D deficient — and the repetitive impact of hiking demands strong bones that D3 and K2 work together to support.

NatureBell combines 5,000 IU of vitamin D3 with 100mcg of vitamin K2 (MK-7) for comprehensive bone health support. Vitamin D3 enhances calcium absorption for stronger bones, supports immune function (critical when hiking in remote areas far from medical care), and maintains muscle strength. Vitamin K2 directs calcium to bones where it’s needed rather than allowing deposits in arteries and soft tissues. The tiny softgel format adds virtually no weight or bulk to a hiking supplement kit, and a single bottle lasts nearly a year.

• Pros:
• Synergistic D3 + K2 combination for optimal bone health
• Tiny softgel format is ultralight for backpacking
• Exceptional value at 300+ servings per bottle

For hikers who want focused beet root supplementation without the complexity of a multi-ingredient blend, this 3-in-1 combines beet root with CoQ10 and grapeseed extract for clean endurance support.

This streamlined formula pairs concentrated beet root powder with CoQ10 for cellular energy production and grapeseed extract for antioxidant protection against UV and environmental exposure during outdoor activity. The simplified formula makes it easy to understand exactly what you’re getting, and the combination targets the specific needs of sustained moderate-intensity exercise like hiking: improved oxygen utilization, enhanced mitochondrial energy production, and protection against the oxidative stress of prolonged outdoor exertion. GMP-certified USA manufacturing.

• Pros:
• Clean 3-ingredient formula with transparent dosing
• CoQ10 supports the sustained energy production hiking demands
• Grapeseed antioxidants complement outdoor UV and environmental exposure

• Cons:

Best for: Hikers who want a simple, focused endurance supplement without complex multi-ingredient formulas

How to Choose the Best Supplements for Hikers

Electrolytes are the most immediately impactful supplement category for hikers. Dehydration and electrolyte imbalance cause fatigue, muscle cramps, dizziness, and impaired cognitive function — all dangerous on the trail. Look for electrolyte products that provide meaningful sodium (200-300mg per serving), potassium, and magnesium. Avoid products loaded with sugar, which can cause GI distress during sustained physical activity. Portability matters for hikers: lightweight tablet or powder formats that fit in a hipbelt pocket are far more practical than heavy bottles of electrolyte drinks.

Joint health supplements become increasingly important for hikers covering high mileage, especially with a loaded pack. Omega-3 fatty acids from fish oil or algae-based supplements reduce inflammation and support joint mobility — a safer long-term strategy than the chronic ibuprofen use common among thru-hikers. A dosage of 1,000-2,000mg combined EPA/DHA daily provides meaningful anti-inflammatory benefits. Magnesium in the bisglycinate or glycinate form prevents cramps and supports the recovery sleep that fuels the next day’s miles.

For multi-day trips, a quality multivitamin compensates for the nutritional deficiencies inherent in typical trail diets. Look for whole-food sourced formulas that include B vitamins for energy metabolism, vitamin D for bone health and immune support, iron for oxygen transport, and probiotics for maintaining gut health under challenging dietary conditions. Beet root supplements provide an edge on demanding trails by improving oxygen efficiency, which is especially noticeable at elevation or during sustained climbs.

Pack weight is a real consideration for backpackers. Choose capsule or tablet formats over heavy bottles and powders when possible. Many supplements can be repackaged into small ziplock bags to reduce container weight. Shelf stability also matters — avoid supplements that require refrigeration or degrade in heat, as trail conditions can include temperature extremes.

Frequently Asked Questions

What supplements should hikers take?

The most important supplements for hikers are electrolytes for hydration, omega-3 fish oil for joint health and inflammation, magnesium for cramp prevention and recovery, and a quality multivitamin to fill the nutritional gaps in typical trail diets. Beet root supplements provide additional endurance support for demanding trails. For multi-day trips, probiotics help maintain gut health, and vitamin D supports bone strength and immune function when dietary variety is limited.

How do I prevent muscle cramps while hiking?

Muscle cramps during hiking are most commonly caused by electrolyte depletion (especially sodium and magnesium) and dehydration. Consume electrolyte tablets or powder mixed into water throughout the day, not just when you feel crampy. Supplementing with magnesium bisglycinate (300-400mg daily) addresses the mineral deficiency that causes most exercise-related cramps. Staying ahead of hydration by drinking small amounts frequently rather than large amounts infrequently also helps prevent cramping.

Should hikers take electrolytes?

Electrolyte supplementation is one of the most beneficial things hikers can do for trail performance and safety. Drinking plain water during heavy sweating can actually worsen electrolyte imbalance by diluting remaining sodium levels — a condition called hyponatremia that can become medically serious. Electrolyte tablets or powders containing sodium, potassium, and magnesium should be consumed during any hike lasting more than 60 minutes or in hot conditions. This is especially critical for high-altitude hikes where dehydration occurs faster.

What is the best anti-inflammatory supplement for hikers?

Omega-3 fish oil is the best anti-inflammatory supplement for hikers. It provides natural anti-inflammatory benefits without the stomach damage, kidney stress, and impaired muscle recovery associated with chronic NSAID (ibuprofen/naproxen) use. A daily dose of 1,000-2,000mg of combined EPA/DHA provides meaningful anti-inflammatory effects. Turmeric with black pepper extract (for bioavailability) is another evidence-based option that can be combined with fish oil for enhanced anti-inflammatory support.

Are supplements worth the extra pack weight for backpacking?

The weight penalty of essential supplements is minimal — a month’s supply of electrolyte tablets, multivitamins, fish oil, and magnesium weighs only a few ounces total. Given the significant performance, recovery, and injury-prevention benefits, supplements offer an excellent weight-to-benefit ratio for backpackers. Repackage supplements from heavy bottles into small ziplock bags to minimize weight. Focus on the highest-impact categories: electrolytes, a multivitamin, magnesium, and omega-3s provide the greatest return for the lightest pack weight impact.

Do hikers need probiotics?

Probiotics are particularly valuable for multi-day hikers and thru-hikers whose diets shift dramatically toward processed, shelf-stable foods lacking the fiber and fermented foods that support healthy gut bacteria. Over 80% of immune function is linked to gut health, making a healthy microbiome essential when hiking in remote areas far from medical care. Choose a shelf-stable probiotic formula that does not require refrigeration — soil-based or spore-forming probiotic strains are the most trail-friendly options as they survive heat and don’t need cold storage.
