All 4 NO Pathways
Works across all four nitric oxide pathways at once — dietary nitrates, your body's own production, antioxidant protection, and critical minerals. Most supplements target just one..
⚛️
Built to Actually Absorb
L-Citrulline bypasses the liver — where up to 70% of direct L-Arginine gets wasted before it reaches your bloodstream. What goes in, gets to work.
🌿
Shields What Your Body Makes
CoQ10, Vitamin C, Grape Seed Extract, and Resveratrol neutralise the free radicals that destroy nitric oxide before it can relax your arteries.
🔬
Clinically Dosed
Every ingredient is dosed to match the exact amounts used in human clinical studies. Not inspired by the research. Built from it.

Did you know that by age 40, your body produces about one-half of the nitric oxide it produced at age 20?
What is nitric oxide and why is it critical to your health?
Nitric oxide is a vasodilator — it helps relax and expand your veins and arteries, promoting healthy blood pressure and blood flow throughout your body. This keeps blood circulating smoothly, delivering nutrients and oxygen to the brain, muscles, and organs, including sexual organs and the skin.
The drop in nitric oxide production that occurs as we age can lead to unhealthy blood pressure levels, an increased risk of heart problems, and poor blood flow to the heart, brain, and sexual organs. Low nitric oxide levels are also associated with stiffened blood vessels and impaired blood vessel function.
Signs of Low Nitric Oxide for Men & Women
Unhealthy Blood Pressure
Poor Sexual Function
Impaired Insulin Responses
Memory Loss
Loss of Exercise Capacity

Your arteries need nitric oxide to relax.
HOW IT WORKS
PowderMAX works across all 4 nitric oxide pathways.
Most blood pressure supplements target just one. That's why they barely move the needle.
01
Nitrate Supply
530mg of NO3-T® patented nitrates per scoop. Human clinical studies show 400mg is the level needed to meaningfully support healthy blood pressure. We went further.
To get this from beet capsules, you'd need 56 of them. Every single day.
One scoop handles it.
• NO3-T® PATENTED NITRATES 530MG
One scoop handles it.
02
Your Body's Own Production
As you age, your body gets less efficient at making its own nitric oxide. Think of it like a bearing in an engine — it slowly wears down.
Most supplements try to solve this with L-arginine. The problem: up to 70% of L-arginine gets processed out by the liver before it reaches your bloodstream. At higher doses it also causes stomach cramps and digestive upset.
PowderMAX uses 3,000mg of L-citrulline instead. It bypasses the liver entirely, travels straight to the kidneys, and converts into L-arginine there — then into nitric oxide. No waste. No stomach issues.
• 3,000MG L-CITRULLINE
03
Nitric Oxide Protection
Here's the part almost every supplement skips.
Even when your body produces nitric oxide, free radicals eat it up before it can reach your arteries. We include four potent antioxidants — each backed by human clinical studies — to stop that from happening.
Grape Seed Extract 300mg. CoQ10 100mg. Vitamin C as Amla Fruit Extract 200mg. Resveratrol 150mg.
Four ingredients. One job. Keep the nitric oxide alive long enough to actually work.
• GRAPE SEED + COQ10 + VITAMIN C + RESVERATROL
04
Critical Minerals
Over 80% of US adults are low in the three minerals most important for heart health: magnesium, potassium, and zinc.
Most supplements use cheap forms the body barely absorbs. We use the most bioavailable forms of all three — Magnesium Bisglycinate, Potassium Citrate, and ZinMax® Zinc — so what goes in actually gets used.
• MAGNESIUM + POTASSIUM + ZINMAX® ZINC
