Ingredient science

Cross-referenced with PubMed & Examine.com

✓No flagged ingredients detected
Caffeine200mg
✓ Proven

Around 3mg per kg of body weight reliably improves endurance performance and focus; count all caffeine sources across the day.

Magnesium25mg
~ Likely

Magnesium supports muscle and nerve function and sleep; many athletes fall short of the recommended intake. Supplementing helps mainly when intake is low. Glycinate and malate forms are well absorbed and gentle on the stomach.

Sodium200mg
✓ Proven

Sodium is the main electrolyte lost in sweat; replacing it supports fluid balance in long or hot sessions.

EAA Blend (as Amino9)7355mg
~ Likely

The amino acids the body can't make; they drive muscle repair, though a full protein serving provides them too.

L-Leucine2790mg
~ Likely

The amino acid that most strongly switches on muscle protein building; about 2–3g per meal, usually from protein, is enough.

L-Lysine1070mg
Disputed

Amino acids used to build collagen; evidence for supplementing them for recovery is limited.

L-Threonine750mg
~ Likely

One of the amino acids in a complete amino acid formula; it contributes to muscle repair alongside the others, as a full protein serving would.

L-Isoleucine614mg
Disputed

A branched-chain amino acid; it adds little on top of an adequate protein intake.

L-Valine580mg
Disputed

A branched-chain amino acid; it adds little on top of an adequate protein intake.

L-Phenylalanine398mg
~ Likely

One of the amino acids in a complete amino acid formula; it contributes to muscle repair alongside the others, as a full protein serving would.

L-Methionine284mg
~ Likely

One of the amino acids in a complete amino acid formula; it contributes to muscle repair alongside the others, as a full protein serving would.

L-Histidine239mg
~ Likely

One of the amino acids in a complete amino acid formula; it contributes to muscle repair alongside the others, as a full protein serving would.

L-Tryptophan40mg
~ Likely

One of the amino acids in a complete amino acid formula; it contributes to muscle repair alongside the others, as a full protein serving would.

Vitacherry Sport (Montomorency Tart Cherry Powder)500mg
~ Likely

Tart cherry has good evidence for reducing muscle soreness after hard exercise and some for sleep quality, mostly from studies using juice or concentrate.

AstraGin (Panax notoginseng Root Extract, Atragalus Root Extract)50mg
Disputed

Ginseng-type herbs are studied for energy, stress and recovery; results are mixed and many studies are small.

Elemin (Ancient Peat Trace Minerals)25mg
Disputed

A source of minerals such as calcium and magnesium; the small amounts add little beyond a normal diet.

Calcium (as Tricalcium Citrate)40mg
~ Likely

An electrolyte and bone mineral; sweat losses are small compared with sodium.

L-Citrulline Malate 2:14000mg
~ Likely

Raises nitric oxide and may modestly improve high-intensity performance at 3–6g; lower doses are less studied.

Beta Alanine2100mg
✓ Proven

Raises muscle carnosine, which buffers acid; around 3–6g a day for at least 4 weeks improves efforts of roughly 1–4 minutes. Harmless tingling is common; split doses reduce it.

Taurine660mg
~ Likely

May reduce exercise-related oxidative stress and modestly improve endurance performance; results are mixed.

Caffeine Anhydrous200mg
✓ Proven

Around 3mg per kg of body weight reliably improves endurance performance and focus; count all caffeine sources across the day.

L-Theanine100mg
~ Likely

An amino acid from tea that promotes relaxation without sedation; 200mg is the typical studied dose and may help sleep quality.
