36 ingredients studied for effects on Energy — sorted by research relevance.

Weak Evidence

Spermidine

Natural polyamine from wheat germ and legumes. Robustly induces autophagy in cell and animal models; early human trials show positive signals for cognition and heart function.

Likely safe
Weak Evidence

L-Carnitin

L-Carnitine shuttles fatty acids into mitochondria. Sounds like a fat burner, but typically delivers less than marketing promises for healthy people.

Likely safe
Strong Evidence

Calcium

Essential mineral for bones, muscles, and nerves. Meta-analyses show moderate bone effects in deficiency; high-dose supplements carry cardiovascular risks.

Likely safe EFSA ✓
Weak Evidence

Astaxanthin

Astaxanthin is a membrane-spanning carotenoid antioxidant. Small RCTs show consistent benefits for skin protection and visual fatigue; cardiovascular and longevity data remain limited.

Likely safe
Weak Evidence

Cordyceps

Cordyceps is marketed for energy and endurance. The evidence is intriguing but mixed—no strong support for major performance claims.

Likely safe
Strong Evidence

Vitamin C (Ascorbic Acid)

Vitamin C is essential for collagen synthesis and other normal body functions, with approved EFSA claims. Megadoses show no clear benefit beyond adequate intake.

Likely safe EFSA ✓
Strong Evidence

Vitamin B6

Vitamin B6 is essential for amino acid metabolism, nerve function, and blood cell formation. Useful for deficiency—chronic high doses can cause nerve damage.

Caution EFSA ✓
Moderate Evidence

EGCG (Grüntee-Extrakt)

EGCG is green tea's most abundant catechin, studied for metabolism and cellular protection. High-dose supplements carry documented liver toxicity risks.

Caution
Strong Evidence

Vitamin B12 (Cobalamin)

Vitamin B12 is essential for nerve function, DNA synthesis, and homocysteine metabolism. Deficiency is common in vegans, older adults, and metformin users and causes irreversible nerve damage.

Safe EFSA ✓
Weak Evidence

Gynostemma (Jiaogulan)

Gynostemma (Jiaogulan) is an adaptogenic herb from Southeast Asia that activates AMPK like metformin, and is associated with longevity in Chinese populations.

Likely safe
Strong Evidence

Vitamin B1 (Thiamin)

Vitamin B1 (thiamine) is essential for energy metabolism and nerve function. Supplements address deficiency and help high-risk groups—not a general anti-aging compound.

Safe EFSA ✓
Strong Evidence

Beta-Alanin

Beta-alanine elevates muscle carnosine and improves high-intensity exercise performance in 60–240-second efforts; it's a sports tool, not a longevity supplement.

Likely safe
Animal Studies Only

Shilajit

Shilajit is marketed for energy, testosterone, and mitochondrial health, but human data is limited and product quality issues are a genuine concern.

Caution
Moderate Evidence

L-Citrullin

L-citrulline may boost nitric oxide production and is linked in studies to improved blood flow and endurance performance during physical exertion.

Likely safe
Weak Evidence

Maca

Marketed for libido, energy, and hormonal balance. Human data exist but are modest in size and strength—weaker evidence than typical promotion suggests.

Likely safe
Strong Evidence

Iron

Essential for oxygen transport, energy metabolism, and immune function. Clearly effective when deficiency is confirmed — do not supplement without a lab diagnosis.

Caution EFSA ✓
Moderate Evidence

Glycin

Glycine is the smallest amino acid, required for glutathione, collagen, and creatine. In GlyNAC form, it shows promise for aging markers in older adults.

Safe
Weak Evidence

Ginseng (Panax)

Ginseng is a classical adaptogen for energy and stress, but evidence is mixed and highly extract-dependent. More serious than trend ingredients, yet less effective than marketing suggests.

Caution
Weak Evidence

Pterostilben

Pterostilbene is a resveratrol analogue from blueberries with superior bioavailability (~80% vs 20%). Similar mechanisms (SIRT1, AMPK) but fewer human studies to date.

Likely safe
Strong Evidence

Caffeine

The world's most widely consumed psychoactive substance. Hundreds of RCTs confirm effects on alertness, reaction time, endurance, and short-term cognition.

Likely safe
Moderate Evidence

Vitamin B3 (Niacin)

Vitamin B3 is essential and a NAD+ precursor. While deficiency correction matters, high-dose niacin causes side effects—benefits for aging in healthy adults remain unclear.

Caution EFSA ✓
Moderate Evidence

Vitamin B2 (Riboflavin)

Vitamin B2 is essential for energy metabolism and antioxidant defence. Most relevant for deficiency correction and potentially for migraine prevention in susceptible individuals.

Safe EFSA ✓
Strong Evidence

Creatine (Creatine Monohydrate)

Creatine is one of the most thoroughly studied supplements for high-intensity muscular work. The strongest evidence is from strength and power sports; further applications are still being explored.

Likely safe EFSA ✓
Strong Evidence

Magnesium

Magnesium is involved in over 300 enzymatic reactions. Low intake is common. The form significantly affects bioavailability and tolerability.

Safe EFSA ✓
Strong Evidence

Phosphor

Phosphorus is essential for bones, ATP and cell membranes. Deficiency is rare, and supplements are unnecessary for most people.

Likely safe EFSA ✓
Strong Evidence

Mangan

Manganese is an essential trace element for enzyme function, bone metabolism and antioxidant systems. Deficiency is rare; supplementation in healthy adults lacks clear evidence of benefit.

Caution EFSA ✓
Moderate Evidence

NMN (Nicotinamide Mononucleotide)

NMN is a direct precursor to NAD+. Animal studies are promising — robust human trials are still lacking, and the EU regulatory status is unclear.

Likely safe
Strong Evidence

Vitamin B5 (Pantothensäure)

Vitamin B5 is essential for CoA and energy metabolism. Deficiency is rare—extra supplements bring little with adequate intake.

Safe EFSA ✓
Strong Evidence

Kupfer

Copper is essential for enzymes, iron metabolism, and connective tissue. Justified for deficiency—but high-dose supplementation isn't advisable for otherwise healthy individuals.

Caution EFSA ✓
Moderate Evidence

Rhodiola Rosea (Rosenwurz)

Rhodiola rosea is an adaptogen with RCT evidence for mental fatigue and stress relief. Data are promising but show some heterogeneity across studies.

Likely safe
Moderate Evidence

Lutein & Zeaxanthin

Xanthophyll carotenoids that concentrate in the macula. Strong evidence for slowing AMD progression (25% reduction in AREDS2). Also studied for contrast sensitivity, glare, and cognitive function.

Safe EFSA ✓
Moderate Evidence

Urolithin A

Urolithin A is a gut microbiome metabolite from pomegranate polyphenols, emerging in aging research as a mitophagy inducer.

Likely safe
Animal Studies Only

Alpha-Ketoglutarat (AKG)

AKG is popular in healthy aging circles, especially as Ca-AKG, but human evidence for anti-aging effects remains extremely limited.

Likely safe
Strong Evidence

Jod

Iodine is essential for thyroid hormones and cognitive development. Germany faces structural deficiency despite salt iodization. EFSA-approved claims.

Caution EFSA ✓
Moderate Evidence

L-Tyrosin

L-Tyrosin is an amino acid precursor of dopamine, noradrenaline, and adrenaline. Studies show cognitive benefits under acute stress and sleep deprivation.

Likely safe
Moderate Evidence

Multivitamin

Multivitamins are the world's best-selling supplements. Evidence for health benefits in well-nourished individuals is surprisingly weak.
