Ingredient science

Cross-referenced with PubMed & Examine.com

✓No flagged ingredients detected
Sodium110mg
✓ Proven

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

Proprietary Blend5.87g
~ Likely

A blend whose individual ingredient amounts aren't disclosed on the label, so the dose of each can't be checked against the research.

L-Citrulline DL-Malate3g
~ Likely

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

Arginine Nitrate (as NO3-T°)1.4g
Disputed

Arginine taken by mouth raises nitric oxide less reliably than citrulline or dietary nitrate; performance benefits in trained people are small or absent.

Careflow Mango Fruit Powder100mg
Disputed

A plant extract marketed for energy or focus; evidence is limited to a few small, industry-funded trials.
