Ingredient science

Cross-referenced with PubMed & Examine.com

✓No flagged ingredients detected
Vitamin B6 (as Pyridoxal-5-Phosphate)5mg
~ Likely

Involved in energy metabolism and making neurotransmitters; supplementing helps only if intake is low.

Vitamin B12 (as Methylcobalamin)100mcg
~ Likely

Needed for red blood cells and nerve function; especially relevant for vegans and vegetarians.

Zinc (as Zinc Chelate)10mg
~ Likely

Zinc supports immune function and tissue repair; athletes lose some in sweat. Helpful if your diet is low in it.

Sodium (as Himalayan Rock Salt)180mg
✓ Proven

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

Potassium (as Potassium Chloride)130mg
~ Likely

An electrolyte involved in muscle and nerve function; sweat losses are much smaller than sodium's.

Citrulline Malate 2:18000mg
~ Likely

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

Beta-Alanine4000mg
✓ 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.

Betaine Anhydrous (BetaPure)2500mg
Disputed

Studied for strength and power; results are mixed.

Taurine1300mg
~ Likely

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

L-Tyrosine1000mg
~ Likely

An amino acid that may help maintain focus under stress or sleep loss; effects on endurance are inconsistent.

AlphaSize 50% Alpha-Glyceryl Phosphoryl Choline (Alpha-GPC)300mg
Disputed

A choline source studied for focus and power output; results are mixed.

PurCaf Organic Caffeine (from Green Coffee Bean) (Coffea arabica) (fruit)200mg
~ Likely

A natural source of caffeine; count it towards your total caffeine intake. Caffeine at around 3mg per kg of body weight improves endurance.

L-Theanine200mg
~ Likely

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

Theobromine50mg
Disputed

A mild stimulant from cocoa; weaker than caffeine, with little evidence for performance.

Senactiv (Panax notoginseng (root), Rosa roxburghii (fruit))50mg
Disputed

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

Bioperine (Piper nigrum) (Black Pepper (Fruit) Extract)5mg
~ Likely

Black pepper extract that can increase absorption of some compounds, such as curcumin.

Boron (as Boron Citrate)3mg
Disputed

A trace mineral studied for bone and joint health and hormones; human evidence is limited and mixed.

Senactiv Tienchi Ginseng (Panax notoginseng) (Root) Extract & Chestnut Rose (Rosa roxburghii) (Fruit) Extract50mg
Disputed

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