Two capsules of a 20% shilajit extract hold 200 mg of fulvic acid. One fluid ounce of a humate-based fulvic liquid holds 180 mg. Those two label lines look alike, yet they come from different raw materials, cost different amounts and have very different research behind them. This guide to the best fulvic acid supplements for energy puts six US products side by side on the numbers that decide a purchase.

Every figure below comes from the product label or the retailer page, read on November 2, 2026. We worked out fulvic acid per day, cost per day at label use and cost per 100 mg of fulvic acid for each bottle. We also checked which products use the same shilajit material as the one human trial that measured fatigue, because that trial is the closest human evidence for an energy-related benefit.

Eternal Elixir makes Shilajit 1000mg; it is our pick, and every figure for the other products is taken from their own labels and retailer pages. If you want the wider shilajit market, including resins, our shilajit supplement comparison covers seven products.

Fulvic acid is a main organic compound in shilajit. The best-studied form is a standardized shilajit extract: 500 mg a day of PrimaVie helped stronger young men keep more strength after fatigue over eight weeks.

Key numbers:

• 8.9% vs 16.0%: drop in maximal strength after a fatiguing test with 500 mg a day of PrimaVie vs placebo, in the stronger half of 63 men (Keller, 2019)
• 250 mg a day of the same extract performed no better than placebo (Keller, 2019)
• 20.7% of 193 Ayurvedic products bought online held detectable lead, mercury or arsenic (Saper, 2008)
• 200 mg to 410 mg of fulvic acid a day across the four capsules compared here (product labels, November 2, 2026)

Best fulvic acid supplements for energy: 6 compared

The table normalizes every product to the lowest daily intake its label suggests. Cost per day is the bottle price divided by the days it lasts at that intake. Prices are the current listed price in USD on November 2, 2026, and shipping terms are the seller’s own. For the Trace liquid, the label lists 250 mg of fulvic acid solution per mL and does not state how much of that solution is fulvic acid, so we did not compute a fulvic figure for it.

Three things stand out in the table. The two cheapest bottles per day are both capsule extracts, and the two liquids cost more per day than every capsule except ours. Only two products, Nature’s Answer and MegaFood, contain PrimaVie, the shilajit extract used in the 2019 fatigue and strength trial. For the bigger picture on what else people use for energy, see our energy supplement comparison.

1. Eternal Elixir Shilajit 1000mg: our pick for a 20% fulvic capsule

Eternal Elixir Shilajit 1000mg is a 20:1 shilajit extract standardized to 20% fulvic acid. Each 2-capsule serving supplies 1,000 mg of extract, which works out to 200 mg of fulvic acid a day at the label serving. The rest of the label is short: a hypromellose capsule, vegetable magnesium stearate and silica, with no added trace-mineral blend or second extract.

The product page labels the evidence by type. It also says plainly that the purified shilajit studied in trials is not established as identical to this product. We think that honesty is worth more than a borrowed claim, and it is why the research section below separates the trial material from what each bottle contains.

Eternal Elixir sells Shilajit 1000mg at $44.99 for 60 capsules, or 30 servings, which is $1.50 a day. That is the highest cost per day of the capsules here, so we do not rank it first on price. It is first because of the 20:1 concentration, the full inactive-ingredient disclosure, a third-party lab test on every batch with the COA available on request, and the option to add Tongkat Ali 200:1 or Korean Panax Ginseng 1600mg to the same order.

If you plan to take shilajit most days, our guide to what happens when you take shilajit daily covers how people build it into a routine and what to watch for in the first weeks. Tongkat Ali and Panax ginseng, covered further down, can ship in the same order.

Key specs:

• Extract: 20:1 shilajit (asphaltum), 20% fulvic acid
• Serving: 2 capsules = 1,000 mg extract = 200 mg fulvic acid
• Bottle: 60 capsules, 30 servings
• Cost: $1.50 per day, $0.75 per 100 mg fulvic acid
• Testing: every batch third-party lab tested, COA on request

Pros:

• High 20:1 concentration with the fulvic percentage declared
• Short label with every inactive ingredient listed
• Stacks in one order with Tongkat Ali and Panax ginseng
• 30-day returns on unopened products

Cons:

• Highest cost per day of the four capsules in this list
• Not the PrimaVie material used in the 2019 trial

Best for: Buyers who want a declared 20% fulvic capsule from a brand that sends a batch COA and sells the rest of an energy stack. Order it with a second product to reach free shipping over $100. Price and where to buy: $44.99 (regular $59.99) for 60 capsules at eternalelixir.com, flat $8 shipping or free over $100.

2. Nature’s Answer Himalayan Shilajit: the trial dose of PrimaVie

Nature’s Answer Himalayan Shilajit uses PrimaVie, a purified shilajit extract with 50% fulvic acid. Two capsules supply 500 mg of PrimaVie, so a serving carries about 250 mg of fulvic acid. That 500 mg daily amount is the same as the higher dose in the 2019 trial on muscle fatigue, which makes this the closest label match to that study in our list.

The price is $20.99 for 60 capsules on Vitacost, or 30 servings at $0.70 a day. Per 100 mg of fulvic acid it costs $0.28, well under half of our figure. The other ingredients are rice flour, a vegetable capsule and calcium silicate, and the label says it is for adults only.

The listing markets it for muscle, energy and sexual wellness, which goes further than the trial data does. Read those words as positioning and use the research section below for what was actually measured.

Key specs:

• Extract: PrimaVie shilajit, 50% fulvic acid
• Serving: 2 capsules = 500 mg extract = 250 mg fulvic acid
• Bottle: 60 capsules, 30 servings
• Cost: $0.70 per day, $0.28 per 100 mg fulvic acid

Pros:

• Same extract and daily amount as the higher-dose arm of the 2019 trial
• Low cost per 100 mg of fulvic acid
• Vegan, gluten-free, kosher and halal per the listing

Cons:

• Smaller total extract per serving than the 1,000 mg capsules
• Marketing language reaches past the trial results

Best for: Buyers who want the PrimaVie material at the dose studied for fatigue. It is the most direct way to copy the trial. Price and where to buy: $20.99 for 60 capsules on Vitacost (read November 2, 2026).

3. MegaFood Shilajit With Fulvic Acid: the most fulvic acid per day

MegaFood Shilajit With Fulvic Acid blends two extracts in each capsule: 400 mg of a 10:1 shilajit extract at 20% fulvic acid and 250 mg of PrimaVie at 50%. The label serving is one capsule, and the directions say to take it twice daily with food. At that intake you get about 410 mg of fulvic acid a day, the highest computed figure in this list.

Two capsules a day also add up to 500 mg of PrimaVie, the trial amount, with the 10:1 extract on top. The bottle holds 60 capsules, so it lasts 30 days at $24.99, or $0.83 a day and $0.20 per 100 mg of fulvic acid. Other ingredients include microcrystalline cellulose, dextrin, stearic acid, silicon dioxide and maltodextrin.

The twice-daily schedule is the main trade-off. People who forget a second dose get half the fulvic acid on those days.

Key specs:

• Blend per capsule: 400 mg 10:1 extract (20% fulvic) + 250 mg PrimaVie (50% fulvic)
• Label use: 1 capsule twice daily with food
• Bottle: 60 capsules, 30 days
• Cost: $0.83 per day, $0.20 per 100 mg fulvic acid

Pros:

• Most fulvic acid per day at label use in this list
• Includes the trial amount of PrimaVie
• Taken with food, which suits sensitive stomachs

Cons:

• Two doses a day
• Longer list of inactive ingredients

Best for: Buyers who want the most fulvic acid per day and can stick to a twice-daily routine. It also covers the PrimaVie trial dose. Price and where to buy: $24.99 for 60 capsules on Vitacost (read November 2, 2026).

4. Nutricost Shilajit: the lowest cost per 100 mg

Nutricost Shilajit lists the same headline as ours: 1,000 mg of a 20:1 shilajit extract with 20% fulvic acid in two capsules. That gives 200 mg of fulvic acid a day. The difference is price. At $14.95 for 120 capsules, a bottle lasts 60 days and costs $0.25 a day, or $0.12 per 100 mg of fulvic acid, the lowest in this list.

The label also lists 30 mg of calcium and 3 mg of iron per serving, which is 14% of the daily value for iron. That small iron amount matters for anyone told to limit iron, so read the panel before you buy. The listing says the product is third-party tested and made in the USA with globally sourced ingredients.

For pure cost per milligram, nothing here beats it. It does not use PrimaVie, so it shares the same research gap as our own capsule. At this price, a two-month trial costs less than one month of most other options here.

Key specs:

• Extract: 20:1 shilajit (asphaltum), 20% fulvic acid
• Serving: 2 capsules = 200 mg fulvic acid
• Bottle: 120 capsules, 60 servings
• Cost: $0.25 per day, $0.12 per 100 mg fulvic acid

Pros:

• Lowest cost per day and per 100 mg of fulvic acid here
• Two-month supply in one bottle
• Third-party tested per the listing

Cons:

• Adds 3 mg of iron per serving
• Not the PrimaVie material from the trial

Best for: Budget buyers who want a 20% fulvic capsule and do not need a matched trial extract. It is the cheapest way to try shilajit. Price and where to buy: $14.95 for 120 capsules on Vitacost (read November 2, 2026).

5. Trace Ionic Fulvic Acid: liquid drops with trace minerals

Trace Ionic Fulvic Acid is a concentrated liquid. Each 1 mL serving lists 250 mg of fulvic acid solution plus 300 mg of ConcenTrace trace minerals, including 15 mg of magnesium and 75 mg of chloride. The label does not say what share of that solution is fulvic acid, so its true fulvic dose is unknown from the panel.

The directions call for 1 mL three times a day, taken straight or in water about 30 minutes before a meal on an empty stomach. At that rate the 2 fl oz bottle, which holds 59 mL, lasts about 20 days. At $20.59, that is $1.05 a day, or about $0.35 per mL.

The listing says it supports energy production, hydration and stamina, among other things. None of the human trials cited here tested this liquid, so treat those words as marketing. The appeal is format: drops are easy to mix into water for people who dislike capsules.

Key specs:

• Per 1 mL: 250 mg fulvic acid solution + 300 mg trace minerals
• Label use: 1 mL three times daily
• Bottle: 2 fl oz (59 mL), about 20 days at label use
• Cost: $1.05 per day

Pros:

• Liquid format with no capsule to swallow
• Adds magnesium and other trace minerals
• Third-party tested per the listing

Cons:

• Fulvic acid content of the solution is not stated
• Three doses a day on an empty stomach

Best for: People who prefer drops in water and want trace minerals in the same serving. Check the fulvic content with the maker before comparing doses. Price and where to buy: $20.59 for 2 fl oz on Vitacost (read November 2, 2026).

6. Vital Earth Minerals Fulvic Minerals: a humate-based liquid

Vital Earth Minerals Fulvic Minerals is a ready-to-drink liquid with 180 mg of fulvic acid per 1 fl oz serving. The label says the fulvic acid comes from vegetal biomass humate and lignite, a plant-derived deposit, rather than from shilajit. The bottle cap doubles as the 1 oz measure, and the directions allow 1 to 3 servings a day with food.

A 32 fl oz bottle costs $34.49, which is $1.08 a day at one serving and $0.60 per 100 mg of fulvic acid. Taking three servings a day would cut the bottle to about 11 days. The Vitacost listing also carries a California Prop 65 warning for reproductive harm, which buyers should read before ordering.

None of the shilajit trials below used a humate or lignite liquid. That leaves this product with a clear fulvic number on the label but no direct energy research behind its source material.

Key specs:

• Source: vegetal biomass humate/lignite
• Serving: 1 fl oz = 180 mg fulvic acid
• Bottle: 32 fl oz, 32 servings at one a day
• Cost: $1.08 per day, $0.60 per 100 mg fulvic acid

Pros:

• Clear fulvic acid figure per ounce
• No capsules, with the cap as a measure
• Taken with food

Cons:

• Different raw material from the studied shilajit extracts
• Prop 65 warning on the listing
• Large bottle to store and ship

Best for: People who want a liquid with a stated fulvic dose and do not mind a different source material. It is the simplest liquid to dose. Price and where to buy: $34.49 for 32 fl oz on Vitacost (read November 2, 2026).

Fulvic acid per dollar, and which labels match the research

Most fulvic acid listings quote a percentage or a solution weight and stop there. The table below turns each label into the same two numbers, then adds where the fulvic acid comes from and whether the bottle contains the material from the human fatigue trial. Cost per 100 mg uses the lowest daily intake on each label.

Shilajit extracts carry the research

Shilajit is a mineral-rich resin from mountain rock, and fulvic acid is one of its main parts. Every human trial in the next section used a shilajit extract, and most used PrimaVie. That is why the last column matters more than the cost column for anyone buying on the strength of a study.

Humate liquids carry a clean number

Fulvic liquids made from humate or lignite give a plain milligram figure per serving, which makes dose math simple. What they lack is trial data on energy for that source material. If a liquid suits you better, choose one that states fulvic acid in milligrams, as Vital Earth does, rather than a solution weight.

How to read a 20:1 or 50% label

An extract ratio such as 20:1 describes how concentrated the raw material is. The fulvic acid percentage describes how much of the finished extract is fulvic acid, so 1,000 mg at 20% means 200 mg. Compare products on fulvic milligrams per day, then on cost per 100 mg, and only then on ratio. Our report on trial doses versus US label doses shows how often those numbers drift apart across categories.

What the energy research on shilajit and fulvic acid measured

The best human evidence comes from a 2019 trial by Keller and colleagues in the Journal of the International Society of Sports Nutrition. Sixty-three recreationally active men took PrimaVie shilajit at 250 mg or 500 mg a day, or a placebo, for eight weeks. In the stronger half of the group, the 500 mg arm kept more of its maximal leg strength after a fatiguing exercise test, and a marker of connective tissue breakdown was lower.

The 250 mg arm did no better than placebo. So the trial supports a dose of 500 mg a day of one specific extract for strength that holds up under fatigue. It did not measure everyday tiredness, mood or alertness, and it tested young men only.

A 2016 study by Das and colleagues in the Journal of medicinal food gave adults with overweight 250 mg of a purified shilajit extract twice a day for eight weeks, then four more weeks with exercise. Muscle biopsies showed higher activity in genes linked to the muscle’s supporting matrix, and blood sugar and lipids did not change. One author listed an affiliation with the research and development unit of Natreon India, a commercial link readers should weigh.

A 90-day trial by Pandit and colleagues in Andrologia gave healthy men aged 45 to 55 purified shilajit at 250 mg twice a day. Total and free testosterone rose compared with placebo. Men who want more on that angle can read our guide to shilajit benefits for men, and women can see what shilajit trials show for women.

Some of the energy story comes from animals. A rat study by Surapaneni and colleagues in the Journal of ethnopharmacology used a processed shilajit with about 57% fulvic acids and found less fatigue-like behavior after repeated forced swimming, along with preserved activity of mitochondrial enzymes. That is a rat result and may not carry over to people.

A 2014 review by Stohs in Phytotherapy research : PTR summed up the field. It says the safety of shilajit is well documented in animal and human studies, names fulvic acid and related compounds as likely active parts, and notes that relatively few well-controlled human studies exist. None of the trials above tested a humate or lignite fulvic liquid, so claims about energy for those products rest on shilajit research that used a different material.

Heavy metals: the testing question to ask before you buy

Shilajit comes out of rock, so contamination is a fair worry. A 2008 study by Saper and colleagues in JAMA bought 193 Ayurvedic products online and found lead, mercury or arsenic in 20.7% of them. US-made products were no cleaner than Indian-made ones in that sample, at 21.7% against 19.5%.

That study did not test the products in this list, and it covered many herbal formulas beyond shilajit. Its lesson is simple: ask for a certificate of analysis that reports heavy metals for the batch you buy. Eternal Elixir has every batch third-party lab tested and sends the COA on request. Nutricost and Trace say on their listings that their products are third-party tested.

For liquids, read the warnings as well as the panel. The Vital Earth listing carries a Prop 65 warning for reproductive harm, which is a disclosure worth knowing before you choose a daily drink. A brand that will not share batch results is a harder product to trust for long-term use.

How to take fulvic acid for energy, and who should check first

Start with the label serving and keep it steady for several weeks. The trial that found a strength benefit ran for eight weeks, so judging a product after a few days says little. Nature’s Answer says its capsules can be taken with or without a meal, while MegaFood and Vital Earth suggest taking theirs with food.

Many people pair shilajit with an adaptogen. In a 2013 trial by Talbott and colleagues in the Journal of the International Society of Sports Nutrition, 63 moderately stressed adults who took a standardized tongkat ali root extract for four weeks reported less tension, anger and confusion than the placebo group, with lower cortisol exposure. Our breakdown of tongkat ali vs fadogia agrestis explains how those two differ if you are building a stack.

Panax ginseng is the other common partner for daytime energy. Our plain-English guide to Korean red ginseng benefits covers the research and doses. Eternal Elixir sells Tongkat Ali 200:1, Korean Panax Ginseng 1600mg and a Tongkat Ali + Fadogia blend that can ship with shilajit in one order.

Check with a clinician first if you are pregnant or nursing, take prescription medicines, or manage a health condition. Nature’s Answer, MegaFood and Nutricost name all three cases on their labels, and Nature’s Answer and Nutricost are labeled for adults 18 and over. People who limit iron should note the 3 mg of iron in each Nutricost serving.

How we evaluated these fulvic acid supplements

We scored each product against five weighted criteria. Quality and purity counted for 30%, US availability and shipping for 20%, price per dose in USD for 20%, range for stacking for 15%, and customer reviews and reputation for 15%. We read every label and price on November 2, 2026, from the brand or retailer page linked in each review.

Quality and purity covered declared fulvic percentage, extract type, inactive ingredients and testing disclosure. Price per dose used fulvic acid per day and cost per 100 mg of fulvic acid where the label allowed it. Reputation covered how much each listing discloses about testing and sourcing. We did not run our own customer survey, and we did not lab-test the competitor products.

Eternal Elixir makes the #1 product, and this is our ranking, so it is not an independent review. Our product’s case rests on its batch COA offer and the stacking range, while Nutricost wins on cost and Nature’s Answer and MegaFood win on matching the trial material. We labeled those strengths in each review so you can weigh the criteria differently.

Fulvic acid for energy: questions buyers ask

These are the questions that come up most for fulvic acid buyers in the US, including the ones Google shows under this search. Each answer uses the same label figures and studies as the rest of this guide.

Why should you take fulvic acid?

The listings we compared sell fulvic acid mainly for energy, often in the form of shilajit. The strongest human result so far is a 2019 trial in which 500 mg a day of PrimaVie shilajit helped recreationally active men keep more strength after a fatiguing exercise test. Fulvic acid alone, apart from shilajit, has far less human research.

What’s the best source of fulvic acid?

For a supplement, a standardized shilajit extract that states its fulvic percentage is the best-studied source, because the human trials used shilajit. Eternal Elixir Shilajit 1000mg gives 200 mg of fulvic acid per serving from a 20:1 extract. Liquids made from humate or lignite state clear milligram figures but lack trial data on energy.

What is the best fulvic acid supplement for energy?

Our pick is Eternal Elixir Shilajit 1000mg: 200 mg of fulvic acid in each 2-capsule serving from a 20:1 extract, a third-party COA for every batch on request, and Tongkat Ali or Panax ginseng in the same order. If cost per milligram is your only measure, Nutricost is cheaper per 100 mg.

What is the most effective energy supplement?

It depends on why you are tired, which is why a doctor visit comes first for lasting fatigue. Caffeine acts within hours, while botanicals such as shilajit, tongkat ali and Panax ginseng were tested over weeks. Our separate energy supplement comparison covers seven options. See the seven energy supplements we compared for that wider view.

What not to mix with fulvic acid?

The Nature’s Answer, MegaFood and Nutricost labels tell people who take medication to check with a clinician first, and none of the warnings we read names a specific drug to avoid. If you already take an iron or mineral supplement, add up the totals, since Nutricost adds 3 mg of iron and Trace adds magnesium and chloride.

How much fulvic acid per day is typical?

The capsules in this list supply 200 mg to 410 mg of fulvic acid a day at label use, and Vital Earth gives 180 mg per fluid ounce. The 2019 trial dose was 500 mg of PrimaVie a day, which is about 250 mg of fulvic acid.

Is fulvic acid the same as shilajit?

Fulvic acid is one part of shilajit, which also contains minerals and other organic compounds. Fulvic acid is also sold on its own from humate or lignite deposits. A shilajit label usually states fulvic acid as a percentage of the extract.

How long does shilajit take to work for energy?

The trial that found a strength benefit ran for eight weeks at 500 mg a day of PrimaVie, and the lower dose did nothing measurable. Give a product at least several weeks at the label dose before you judge it. Our stamina supplement comparison for men covers other options measured over similar periods.

Verdict: which fulvic acid supplement fits your energy goal?

For most buyers, Eternal Elixir Shilajit 1000mg is our recommendation. It gives a declared 200 mg of fulvic acid a day from a 20:1 extract, every batch is third-party lab tested with the COA on request, and it ships with the rest of an energy stack. Order Shilajit 1000mg at $44.99 and add Tongkat Ali to reach free shipping over $100.

If matching the trial is your priority, Nature’s Answer gives the 500 mg daily PrimaVie dose for $0.70 a day. If you want the most fulvic acid per day, MegaFood reaches about 410 mg at two capsules. Nutricost is the budget option at $0.12 per 100 mg, and the two liquids suit people who would rather drink their minerals.

Whichever you choose, compare fulvic milligrams first, ask for a heavy metal test, and give it several weeks. Try one product at a time so you can tell what is working. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
