Feeling tired and sluggish is a common struggle in today’s fast-paced world. Many of us reach for caffeine or energy drinks for a quick boost, but these solutions often lead to crashes later in the day. Natural energy supplements can provide sustained vitality without the harsh side effects of synthetic alternatives.

I’ve researched the most effective energy supplements that actually work, from B vitamins to adaptogenic herbs like ashwagandha. These natural options work with your body’s systems rather than against them, helping to support long-term energy production instead of just masking fatigue temporarily.
1) Iron supplements – Available at NATURELO

Iron is a crucial mineral that helps our bodies produce red blood cells and transport oxygen throughout the body. When our iron levels are low, we often feel tired and lack energy – a common issue that many of us face.
NATURELO offers an excellent iron supplement with Vitamin C that I find particularly effective. Their formula provides 25mg of iron per serving, which helps boost energy levels naturally.
What makes this supplement special is its gentle formula. Many iron supplements can cause stomach upset, but NATURELO’s version includes vitamin C from organic acerola cherries to improve absorption while being gentle on your digestive system.
I’m impressed by their iron-rich whole food blend that includes organic beet, spinach, and kale. These natural ingredients complement the iron and provide additional nutrients.
This supplement is perfect for vegans, vegetarians, and anyone with increased iron needs like pregnant women or athletes. Many customers report increased energy levels and improved iron counts without the constipation or nausea often associated with iron supplements.
NATURELO offers this supplement in both 90-capsule and 180-capsule bottles. I recommend starting with the smaller size to see how it works for your body.
2) Vitamin B12 oral sprays – Purchase online at BetterYou

Vitamin B12 oral sprays offer a convenient way to boost energy levels. These sprays are absorbed directly through the mouth’s mucous membrane, bypassing digestive issues that can affect pill absorption.
BetterYou makes excellent B12 sprays that deliver this essential vitamin directly into your bloodstream. Their Boost B12 Oral Spray provides 1,200mcg of methylcobalamin, the most bioavailable form of B12.
People who follow vegetarian or vegan diets particularly benefit from B12 supplementation. Others who may need extra B12 include older adults, those with certain digestive conditions, and people experiencing persistent fatigue.
I’ve found that regular use of B12 spray can help combat tiredness and improve mental clarity. The spray format makes it easy to use anytime, anywhere – perfect for busy lifestyles.
BetterYou’s products are well-reviewed for their effectiveness and pleasant taste. Their sprays are also free from artificial preservatives and flavors, making them a healthier choice.
3) Coenzyme Q10 (CoQ10) – Shop at Nature Made®

CoQ10 is a powerful compound our bodies naturally produce that helps generate energy in our cells. As we age, our CoQ10 levels naturally decline, which can leave us feeling more tired and sluggish throughout the day.
I’ve found that supplementing with CoQ10 can help boost energy levels, especially for adults over 40. It works by supporting mitochondrial function—these are the tiny powerhouses in your cells that convert nutrients into energy.
Nature Made offers several excellent CoQ10 options through iHerb. Their CoQ10 100 mg softgels are perfect for beginners looking to support their energy levels. This supplement is easy to take—just one softgel daily with a meal.
For those needing more robust support, I recommend their CoQ10 400 mg softgels. This higher potency formula is especially beneficial for people taking statin medications, which can deplete natural CoQ10 levels.
Nature Made is the #1 pharmacist-recommended supplement brand, and their CoQ10 products are USP verified for quality and purity. This verification means you’re getting exactly what’s on the label—no fillers or contaminants.
The 200 mg version offers a middle-ground option with 80 softgels per bottle, making it a great value for consistent users. Many of my clients report noticeable improvements in energy within 2-3 weeks of regular use.
CoQ10 supplements particularly benefit those with active lifestyles, heart concerns, or anyone experiencing age-related fatigue. It’s also great for supporting overall heart health while boosting your daily energy.
4) Ginseng extract – Find at your local health store

Ginseng is one of my favorite natural energy boosters. This powerful herb has been used for centuries in traditional medicine to fight fatigue and increase stamina without the crash that comes with caffeine.
Asian Ginseng extract helps your body adapt to stress while supporting healthy energy levels. I’ve found it particularly helpful during busy workweeks when I need sustained focus without jitters.
The way ginseng works is fascinating – it helps optimize how your body uses oxygen and supports adrenal function. This makes it especially beneficial for people dealing with mental fatigue or those recovering from illness.
I recommend checking out the alcohol-free Asian Ginseng extract from iHerb. At 840 mg per serving, it provides a potent dose that many users find effective for energy support.
This liquid formula can be easily added to smoothies or other beverages. I appreciate that it’s alcohol-free, making it suitable for more people, including those who avoid alcohol for religious or health reasons.
For those new to ginseng, I suggest starting with a lower dose to see how your body responds. Most people notice benefits within a few days of consistent use.
5) Ashwagandha capsules – Order from Cymbiotika

Ashwagandha is one of my favorite adaptogenic herbs for natural energy support. This ancient Ayurvedic herb helps the body adapt to stress while promoting sustained energy without the crash you might experience with caffeine.
I’ve found that ashwagandha works by helping to balance cortisol levels, which can reduce feelings of stress and fatigue. It’s particularly beneficial for people experiencing burnout or those who feel “tired but wired” throughout the day.
Zahler Ashwagandha 600 offers a clinically validated dose that supports mental energy and relaxation. I appreciate that it comes in a convenient capsule form with 600mg per serving.
Athletes and busy professionals may notice the most significant benefits from ashwagandha. Research suggests it can help improve physical performance while supporting a calm, focused mind.
For those who prefer a different delivery method, I’ve also seen great results with Phytoral Ashwagandha Complex Gummies, which combine ashwagandha with tart cherry for additional benefits.
The effects of ashwagandha tend to build over time, so consistency is key. I typically recommend taking it daily for at least 2-4 weeks to experience the full energy-enhancing benefits.
6) Green tea extract – Available from Care/of

Green tea extract is one of my top recommendations for natural energy support. This powerful supplement contains caffeine and L-theanine that work together to provide smooth, sustained energy without the jitters or crash associated with coffee.
The key active compounds in green tea extract are polyphenols and catechins, which are known for their antioxidant properties. These compounds help protect your cells from damage while supporting healthy metabolism and energy production.
I find green tea extract particularly beneficial for people who need mental clarity along with physical energy. The L-theanine promotes calm focus while the caffeine provides stimulation—a perfect combination for productive work.
One standout product I recommend is NOW Green Tea Extract, which offers 400 mg per capsule. This concentrated form delivers the benefits of 2-3 cups of green tea in one convenient dose.
For those seeking higher EGCG content (the most potent catechin), I suggest trying NOW’s EGCG Green Tea Extract with 200 mg of EGCG per capsule. Many users report improved energy levels and mental clarity with regular use.
I recommend taking green tea extract in the morning or early afternoon to avoid sleep disruption. Start with a lower dose to assess your tolerance, especially if you’re sensitive to caffeine.
7) Creatine monohydrate – Sold at major supplement retailers

Creatine monohydrate is one of the most researched and effective supplements for boosting energy during workouts. I find it particularly valuable for providing quick energy to muscles during high-intensity exercise, helping many people push through their fitness plateaus.
This supplement works by increasing your body’s phosphocreatine stores, which helps produce more ATP (adenosine triphosphate) – your cells’ primary energy currency. When your muscles have more ATP available, you can maintain higher intensity during workouts.
Athletes and fitness enthusiasts benefit most from creatine, but anyone looking for improved physical performance can see results. It’s especially helpful for short bursts of intense activity like weightlifting, sprinting, or high-intensity interval training.
Creatine Monohydrate from MRM Nutrition is a highly-rated option that can help increase muscle mass quickly. Each serving provides pure creatine to support strength and energy during workouts.
For those who prefer capsules, Nutricost Performance Creatine Monohydrate offers 3g per serving and may help increase strength, endurance, and energy levels.
I recommend taking creatine consistently for best results, as it works through accumulation in your muscles over time. Some research even suggests taking it after workouts may provide slightly better results than pre-workout timing.
8) Tyrosine supplements – Available in sports nutrition shops

Tyrosine is an amino acid that plays a key role in producing neurotransmitters that help with energy and focus. I’ve found it particularly useful when I need mental alertness during demanding tasks or stressful situations.
This supplement works by helping your body produce important brain chemicals like dopamine, adrenaline, and noradrenaline. These chemicals are crucial for maintaining energy levels and supporting brain function throughout the day.
L-tyrosine supplements can be especially beneficial for people who experience mental fatigue or need to stay alert during high-pressure situations. Many athletes and professionals use it to maintain concentration when tired.
For those looking for a quality option, NOW Foods L-Tyrosine offers 500mg capsules that are well-regarded by many users. These capsules provide an effective dose that can help support mental performance.
Another excellent choice is Doctor’s Best L-Tyrosine, which comes in veggie caps for those with dietary preferences. Their formula is designed to support brain function and enhance mental performance.
I recommend taking tyrosine supplements on an empty stomach for best absorption, ideally in the morning. This timing helps maximize the energy-supporting benefits throughout the day.
9) Protein powder with branched-chain amino acids
Protein powder with branched-chain amino acids (BCAAs) offers excellent energy benefits for active people. These supplements provide the essential amino acids our bodies need for muscle recovery and growth, which directly impacts energy levels.
I’ve found that BCAAs are particularly valuable during workouts as they help reduce fatigue and muscle soreness. When your muscles recover faster, you naturally have more energy for daily activities and future exercise sessions.
Athletes and fitness enthusiasts benefit most from these supplements, but anyone experiencing energy slumps might find them helpful. BCAAs work by providing a readily available source of amino acids that support muscle protein synthesis.
Optimum Nutrition’s Instantized BCAA 5000 Powder is a highly-rated unflavored option that many users report enhances workout performance and energy levels. Its unflavored formula makes it versatile for mixing with different beverages.
For those who prefer flavored options, EVLution Nutrition’s BCAA Energy in Green Apple combines BCAAs with natural energizers. It dissolves easily in water and can be enjoyed during workouts or throughout the day.
I recommend looking for products that contain a 2:1:1 ratio of leucine, isoleucine, and valine for optimal results. The quality of ingredients matters, so check product labels carefully before purchasing.
BPI Sports Best BCAA is another excellent choice, with many customers praising its effectiveness for enhancing workout performance. It’s designed to support fat loss while aiding in muscle growth and recovery.
I encourage you to explore iHerb’s complete selection of BCAA products to find the one that best suits your specific energy needs and taste preferences.
10) Multivitamin for energy – Check VitaBright products
Multivitamins can fill nutritional gaps that might be leaving you tired throughout the day. I find that VitaBright multivitamins contain essential B vitamins, iron, and other nutrients that directly support energy production in our cells.
These supplements work by providing the key nutrients your body needs to convert food into usable energy. When you’re deficient in even one essential vitamin, your energy systems may not function optimally.
VitaBright Multi-Energy is particularly popular among customers for its balanced formula. It’s great for busy adults, athletes, and anyone experiencing afternoon slumps.
Morning fatigue often improves within a few weeks of consistent use. I recommend taking it with breakfast to maximize absorption and energy benefits throughout the day.
You can find VitaBright products on iHerb with competitive pricing and frequent discounts. Their multivitamins typically include energy-supporting ingredients like CoQ10 and green tea extract alongside traditional vitamins and minerals.
Understanding Natural Supplements for Energy
Natural supplements can provide a reliable energy boost without the crash often associated with caffeine or sugar. These products work with your body’s natural processes to improve energy production at the cellular level.
How Supplements Enhance Energy Levels
Energy supplements work through several mechanisms in the body. Many target mitochondria—our cells’ power plants—to improve ATP production, which is the energy currency of our cells.
Some supplements, like Vitamin D, play a key role in breaking down food into usable energy. This helps with sugar metabolism, potentially supporting more consistent energy levels throughout the day.
Adaptogenic herbs like ginseng help the body resist physical and mental fatigue. Research shows ginseng can significantly reduce overall fatigue symptoms.
Other supplements enhance oxygen delivery to tissues or support adrenal function, which regulates our stress response and energy levels.
Common Ingredients in Energy Supplements
Coenzyme Q10 (CoQ10) is essential for energy production in every cell. As we age, natural CoQ10 levels decline, making supplementation potentially beneficial for maintaining energy levels.
B vitamins (especially B12) are crucial for converting food into energy. Deficiencies often manifest as fatigue and weakness.
Adaptogenic herbs include:
- Ashwagandha – reduces stress while improving mental clarity
- Rhodiola – fights physical and mental fatigue
- Ginseng – enhances physical performance and mental focus
Amino acids like L-carnitine transport fatty acids into mitochondria for energy production. This makes them particularly useful for physical performance.
Berberine and quercetin are also gaining popularity for their energy-supporting benefits.
Safety and Efficacy of Natural Energy Supplements
Natural energy supplements can vary widely in both safety and effectiveness. When considering these products, it’s crucial to understand quality indicators and potential health concerns.
Choosing Quality Supplements
When I look for energy supplements, I check for third-party testing and certifications first. Reputable brands like those found on iHerb often have USP, NSF, or GMP certifications that verify ingredient quality and manufacturing standards.
The supplement form matters too. Some nutrients are better absorbed as capsules, while others work well as powders or liquids. I always check the ingredient list for fillers, artificial colors, and unnecessary additives.
Dosage is another critical factor. Some energy supplements like B vitamins and CoQ10 have established effective ranges, while herbal products may vary. I’ve found that supplements containing standardized extracts typically provide more consistent results.
Price doesn’t always indicate quality. Many excellent supplements are reasonably priced, especially when purchased from trusted online retailers.
Potential Side Effects to Consider
Even natural supplements can cause unwanted effects. Caffeine-containing products like guarana may cause jitteriness, insomnia, or increased heart rate. I’ve noticed that taurine and other common energy boosters can provide quick energy but sometimes lead to crashes afterward.
Herbal energy supplements like ashwagandha and Rhodiola may interact with certain medications. I always check with my doctor before starting any new supplement, especially if I take prescription drugs.
Some people experience digestive issues with certain supplements. For example, B vitamins on an empty stomach can cause nausea in sensitive individuals.
Detox-promoting supplements might cause temporary headaches or fatigue as the body adjusts. This is why I start with lower doses of detoxifying supplements and gradually increase as tolerated.
