Top 10 Supplements for Energy 2027

Direct Answer

The Best Overall energy supplement for 2027 is Thorne Creatine, about $45 for 90 servings, which delivers 5 g of Creapure creatine monohydrate per scoop — the most-researched compound for cellular energy and exercise capacity — from an NSF Certified for Sport brand.

The Best Value pick is Nature Made Vitamin B12, roughly $10 for 150 tablets, which supports normal energy metabolism at a few cents per serving with USP verification, ideal for anyone low in B12. This guide is built for readers chasing steady physical and mental energy — athletes, busy professionals, and anyone fighting afternoon slumps — who want evidence-backed, third-party-tested products rather than mega-dosed stimulant blends.

Budgets here run from about $10 to $50. These supplements support normal energy-yielding metabolism; they do not treat fatigue caused by medical conditions, and you should consult a clinician before starting, especially if pregnant, on medication, or persistently tired.

How We Ranked the Top 10

We weighted each supplement against what evidence-minded buyers actually care about, drawing on Examine.com, Healthline, the NIH Office of Dietary Supplements, ConsumerLab, and manufacturer certificates of analysis. The weighting:

• Effectiveness and evidence — 25%
• Quality and third-party testing — 20%
• Form and absorption — 15%
• Value and price per serving — 15%
• Purity and safety — 15%
• Brand transparency and support — 10%

A supplement with strong human evidence and clean third-party testing rises; a proprietary stimulant blend with vague dosing and no testing drops fast. The winners balance all six, and several work through nutrition rather than stimulation.

1. Thorne Creatine 🏆 BEST OVERALL

Type: Supplement (powder) | Price: $45 / 90 servings | Best for: Anyone wanting research-backed physical and mental energy support

Thorne Creatine provides 5 g of Creapure creatine monohydrate per scoop — the gold-standard German-made form — supporting the body's ATP energy system for both muscle performance and, in growing research, cognitive output under demand. Creatine is among the most-studied supplements in existence, with consistent evidence for strength, power, and recovery.

Thorne carries NSF Certified for Sport, screening every lot for banned substances and label accuracy, and the unflavored powder mixes cleanly with no fillers. Reviewers and practitioners rank Thorne among the most trusted brands for tested, single-ingredient products.

Pros:

• 5 g Creapure creatine monohydrate, the most-researched energy compound
• NSF Certified for Sport with per-lot banned-substance screening
• Unflavored, filler-free powder that mixes cleanly
• Backed by extensive human evidence for performance and recovery

Cons:

• Requires daily consistency to build muscle saturation
• Mild water-weight gain is common early on

Verdict: Thorne Creatine wins on the deepest evidence base, an elite tested form, and broad energy and performance support.

2. Nature Made Vitamin B12 💎 BEST VALUE

Type: Supplement (tablet) | Price: $10 / 150 tablets | Best for: Buyers low in B12 who want energy-metabolism support cheaply

Nature Made Vitamin B12 delivers 1,000 mcg per tablet and carries USP verification, confirming identity, potency, and purity. Vitamin B12 supports normal energy-yielding metabolism and red blood cell formation, and supplementation is especially useful for vegans, older adults, and anyone with low B12 status, where deficiency genuinely causes fatigue.

At under $0.07 per tablet, it is by far the cheapest serving here. Reviewers note that B12 only boosts energy when you are actually low — but for those people the effect is meaningful and the value unbeatable.

Pros:

• Lowest cost per serving on the list at under $0.07
• USP Verified for identity, potency, and purity
• Supports normal energy metabolism and red blood cell formation
• Especially valuable for vegans and older adults

Cons:

• Little benefit for people who are not deficient
• Tablet form absorbs slightly slower than sublingual versions

Verdict: Nature Made B12 is the value champion — a USP-verified, energy-metabolism nutrient at pennies per serving.

3. Optimum Nutrition Micronized Creatine

Type: Supplement (powder) | Price: $30 / 114 servings | Best for: Buyers who want proven creatine at the best price per gram

Optimum Nutrition Micronized Creatine offers 5 g of Creapure monohydrate per serving with 114 servings per tub, one of the best costs per gram available. The micronized powder dissolves easily, and Optimum Nutrition is Informed Choice tested for banned substances on many products.

It pairs the same proven, well-researched compound as our top pick with a lower price, making it the smart choice for buyers who want creatine's energy and performance benefits on a budget. Reviewers consistently rate it a dependable staple.

Pros:

• 5 g Creapure creatine at a very low cost per serving
• Micronized for easy mixing and fast dissolution
• Informed Choice banned-substance testing
• 114 servings per tub for excellent long-term value

Cons:

• Larger brand with less granular published testing than Thorne
• Unflavored powder can be gritty if under-mixed

Verdict: Optimum Nutrition is the budget creatine pick — the same proven compound as our winner at a lower cost per gram.

4. Nature Made CoQ10

Type: Supplement (softgel) | Price: $20 / 60 softgels | Best for: Older adults and statin users supporting cellular energy

Nature Made CoQ10 provides 200 mg of coenzyme Q10 per softgel, a compound involved in mitochondrial energy production within cells. Natural CoQ10 levels decline with age and can be lowered by statin medications, making supplementation relevant for older adults and statin users.

The product is USP verified and uses a softgel for better absorption of the fat-soluble nutrient. Reviewers value the verification and the targeted use case, though evidence for energy in healthy younger people is more limited.

Pros:

• 200 mg CoQ10 supporting mitochondrial energy production
• USP Verified for identity, potency, and purity
• Softgel form aids absorption of the fat-soluble nutrient
• Relevant for older adults and statin users

Cons:

• Limited benefit for healthy younger people
• Ubiquinol forms may absorb better for some users

Verdict: Nature Made CoQ10 is the cellular-energy pick — most useful for older adults and those on statins.

5. Klean Athlete Klean Caffeine

Type: Supplement (tablet) | Price: $18 / 100 tablets | Best for: Buyers wanting a clean, precisely dosed caffeine source

Klean Athlete Klean Caffeine delivers a precise 100 mg of caffeine from green tea per tablet, giving controllable, measured stimulation without the sugar of energy drinks. Caffeine has the strongest evidence of any energy compound for alertness and performance, and a measured tablet avoids the guesswork of pre-workout blends.

Klean Athlete is NSF Certified for Sport, so each lot is screened for banned substances. Reviewers like the clean, single-ingredient approach and the ability to dial dosing precisely. Avoid late-day use and watch total daily caffeine.

Pros:

• Precise 100 mg caffeine dose from green tea per tablet
• NSF Certified for Sport, screened for banned substances
• Strong evidence for alertness and exercise performance
• No sugar, calories, or proprietary stimulant blends

Cons:

• Stimulant effect is temporary, not a baseline fix
• Late-day use can disrupt sleep

Verdict: Klean Caffeine is the clean-stimulant pick — measured, tested caffeine without energy-drink baggage.

6. Thorne Iron Bisglycinate

Type: Supplement (capsule) | Price: $13 / 60 capsules | Best for: Buyers with low iron — a real and common cause of fatigue

Thorne Iron Bisglycinate provides 25 mg of gentle, well-absorbed iron per capsule in a chelated form that is easier on the stomach than ferrous sulfate. Iron deficiency is one of the most common nutritional causes of genuine fatigue, especially in menstruating women, and correcting it can meaningfully restore energy — but only when you are actually low.

Thorne carries NSF Certified for Sport and publishes its testing. Reviewers praise the gentle form, but the key is to test iron levels with a clinician first, since excess iron is harmful.

Pros:

• 25 mg gentle, well-absorbed iron bisglycinate
• NSF Certified for Sport with published testing
• Easier on digestion than standard ferrous sulfate
• Addresses a real, common cause of fatigue when deficient

Cons:

• Should only be taken if blood tests confirm low iron
• Excess iron is harmful, so self-dosing is risky

Verdict: Thorne Iron is the deficiency-correction pick — powerful for fatigue only when blood tests confirm you are low.

7. Momentous Vital Aminos (EAAs)

Type: Supplement (powder) | Price: $50 / 30 servings | Best for: Active buyers supporting recovery and sustained training energy

Momentous Vital Aminos delivers a full spectrum of essential amino acids (EAAs) per scoop to support muscle recovery and reduce training-related fatigue across demanding schedules. Better recovery translates to more consistent day-to-day energy for active people. Momentous is NSF Certified for Sport and Informed Sport certified, a dual standard trusted by pro and collegiate athletes.

The powder mixes easily and is sugar-free. Reviewers value the rigorous testing, though the per-serving cost is the highest on this list.

Pros:

• Full essential amino acid profile for recovery support
• NSF Certified for Sport and Informed Sport certified
• Sugar-free powder that mixes easily
• Trusted by professional and collegiate athletes

Cons:

• Highest cost per serving on the list at around $1.67
• Benefit is indirect, via recovery rather than acute energy

Verdict: Momentous Vital Aminos is the recovery pick — sustained energy for active people through better recovery.

8. Nature Made Iron-Free Multivitamin

Type: Supplement (tablet) | Price: $12 / 90 tablets | Best for: Buyers covering nutrient gaps that can quietly sap energy

Nature Made Multi For Him/Her provides a broad base of vitamins and minerals — including B vitamins, vitamin D, and magnesium — that support normal energy-yielding metabolism. A daily multivitamin won't create energy out of nothing, but it insures against the micronutrient gaps that quietly cause sluggishness in people with imperfect diets.

The product is USP verified and affordably priced. Reviewers see it as sensible nutritional insurance rather than a stimulant, and the verification gives confidence in the label.

Pros:

• Broad B-vitamin and mineral base for energy metabolism
• USP Verified for identity, potency, and purity
• Affordable daily nutritional insurance
• Covers gaps common in imperfect diets

Cons:

• No acute or noticeable energy boost
• Whole-food diet may make it redundant for some

Verdict: Nature Made Multi is the nutrient-insurance pick — covers the gaps that quietly drain energy.

9. NOW Foods Rhodiola

Type: Supplement (capsule) | Price: $16 / 60 capsules | Best for: Buyers seeking an adaptogen for stress-related fatigue

NOW Foods Rhodiola provides 500 mg of Rhodiola rosea standardized to 3% rosavins and 1% salidroside per capsule, an adaptogenic herb studied for stress-related and mental fatigue. Some human research suggests rhodiola may help reduce perceived fatigue during demanding periods.

NOW operates GMP-certified facilities with an in-house analytical lab and discloses standardization. Reviewers value the disclosed actives and low price, though the evidence base is smaller than for creatine or caffeine. It is a non-stimulant option for stress-driven tiredness.

Pros:

• 500 mg standardized Rhodiola rosea with disclosed actives
• GMP-certified facilities with in-house testing
• Non-stimulant adaptogen for stress-related fatigue
• Low cost per capsule and vegan-friendly

Cons:

• Smaller evidence base than creatine or caffeine
• Effects on fatigue vary considerably between people

Verdict: NOW Rhodiola is the adaptogen pick — a non-stimulant option for stress-driven mental fatigue.

10. Liquid I.V. Hydration Multiplier

Type: Supplement (powder packet) | Price: $25 / 16 packets | Best for: Buyers whose low energy is really mild dehydration

Liquid I.V. Hydration Multiplier uses an electrolyte and glucose blend to speed fluid absorption, addressing the mild dehydration that frequently masquerades as low energy. Each stick adds sodium, potassium, and a touch of B vitamins to water.

For people who simply aren't drinking enough — common during travel, heat, or exercise — better hydration can restore alertness more effectively than any stimulant. Reviewers like the taste and convenience, though the added sugar and sodium mean it is best used situationally, not constantly.

Pros:

• Electrolyte blend that speeds fluid absorption
• Addresses dehydration, a common hidden cause of low energy
• Convenient single-serve travel packets
• Added B vitamins and pleasant flavor

Cons:

• Contains added sugar and significant sodium
• Best used situationally, not as a daily habit

Verdict: Liquid I.V. Is the hydration pick — restores energy when the real problem is simply being under-hydrated.

Which One Is Right for You?

What to Look For in an Energy Supplement

• Real human evidence — Favor compounds with strong research like creatine, caffeine, and correcting B12 or iron deficiency. Be skeptical of proprietary "energy blends" with undisclosed doses.
• Third-party testing — Look for USP, NSF Certified for Sport, Informed Sport, or a published certificate of analysis to confirm purity and label accuracy.
• The right mechanism for you — Energy problems differ: deficiency, dehydration, poor recovery, or simply needing alertness. Match the supplement to the actual cause.
• Sensible stimulant levels — If using caffeine, track total daily intake and avoid late-day doses that wreck sleep — the most common real energy thief.
• Clean formulas — Skip mega-dosed blends, excessive added sugar, and undisclosed ingredients in favor of single, well-dosed actives.
• Sustainable use — The best long-term energy comes from sleep, nutrition, and movement; supplements fill specific gaps rather than replace fundamentals.

What matters less than marketing implies: flashy "energy formula" branding, towering caffeine doses, and long proprietary ingredient lists. Correcting a genuine deficiency or hydration gap beats any stimulant blend, and sleep beats them all.

FAQ

Which energy supplement is the best overall for 2027? Thorne Creatine at about $45 earns our top spot — 5 g of Creapure creatine is the most-researched compound for cellular energy and performance, from an NSF Certified for Sport brand.

What is the best value energy supplement? Nature Made Vitamin B12 at roughly $10 is the value leader, supporting normal energy-yielding metabolism at pennies per serving with USP verification — especially useful if you are low in B12.

Do energy supplements actually work? Some do, when matched to the cause. Caffeine reliably boosts alertness, creatine supports performance, and correcting a B12 or iron deficiency restores energy in deficient people. They do not treat fatigue from medical conditions — see a clinician for persistent tiredness.

Are stimulant-free energy options available? Yes. Creatine, B12, iron (if deficient), CoQ10, rhodiola, and hydration all support energy without caffeine. Match the choice to whether your issue is deficiency, recovery, stress, or hydration.

Is it safe to take caffeine supplements daily? Moderate caffeine — up to about 400 mg per day for most healthy adults per FDA guidance — is generally considered safe, but it disrupts sleep if taken late and can cause jitters. Consult a clinician if you are pregnant, have heart issues, or are sensitive.

Why am I still tired despite taking supplements? Supplements only help if they target your actual cause. Persistent fatigue often stems from poor sleep, stress, dehydration, or an underlying medical condition. If tiredness continues, see a clinician rather than adding more supplements.

Bottom Line

For 2027, Thorne Creatine is our Best Overall energy supplement — about $45 for 5 g of Creapure creatine, the most-researched compound for cellular energy and performance, backed by NSF Certified for Sport testing. Nature Made Vitamin B12, near $10, is our Best Value, supporting normal energy metabolism at pennies per serving with USP verification.

If your low energy comes from caffeine cravings, low iron, stress, dietary gaps, or dehydration, use the decision tree above to route yourself to Klean Caffeine, Thorne Iron, NOW Rhodiola, Nature Made Multi, or Liquid I.V. Match the supplement to the real cause, prioritize sleep and nutrition, and consult a clinician before starting anything new.
