Blue Horse Ingredients

Quick Answer

Blue Horse contains seven named actives with exact doses — L-Arginine 400 mg, L-Arginine AKG 400 mg, L-Citrulline HCL 200 mg, L-Citrulline Malate 200 mg, Beta-Alanine 80 mg, Niacin 15 mg NE and Calcium 36 mg — for blood flow and performance.

Seven blood-flow actives, every dose on the label

Blue Horse names every ingredient and its exact amount — no hidden proprietary blend. Here's the full line-up per two-capsule serving and what each one contributes to blood flow and performance.

🩸
400 mg · Nitric-oxide precursor

L-Arginine

A key amino acid your body uses to make nitric oxide, the signal that tells blood vessels to relax and widen for healthy circulation and better pumps.

⚡
400 mg · Enhanced uptake

L-Arginine AKG 2:1

L-Arginine bound to alpha-ketoglutarate for efficient cellular uptake, so more of it is available to support nitric-oxide production and blood flow.

🔄
200 mg · Sustained NO

L-Citrulline HCL

Converted back into L-Arginine in the body, bypassing first-pass breakdown to keep nitric-oxide support going for hours.

💪
200 mg · Endurance

L-Citrulline Malate

The malate form pairs sustained nitric-oxide support with cellular energy, helping fuel stamina and workout endurance.

🔥
80 mg · Buffers fatigue

Beta-Alanine

A performance amino acid that supports muscular endurance and helps buffer the fatigue that builds during effort.

💧
15 mg NE · Circulation

Niacin (Vitamin B3)

Supports healthy circulation, energy metabolism and normal blood flow, helping deliver oxygen and nutrients where they're needed.

🦵
36 mg · Muscle function

Calcium

An essential mineral that supports healthy muscle function and contraction as part of everyday performance.
