AltiFuel is the altitude athletes best friend by providing higher Iron content for blood oxygenating red blood cells, pushes back at altitude sickness, hypoxia & increases aerobic support.

AltiFuel3 ES was made for high-level athletes who train, race, and climb at elevation. Of the two AltiFuel formulas, this is the one that carries the Highest Octane label, powered by Mercenaria mercenaria clams instead of desiccated liver. Clams carry more iron, and their iron is heme iron, the form your body absorbs best. Around them, cordyceps supports energy, ginkgo supports healthy blood flow, and rhodiola helps your body settle into altitude.
At 8,000 feet, each breath gives you about 25 percent less oxygen than at sea level. Most athletes feel it within hours. Your heart works harder, sleep gets lighter, and an easy pace starts to feel hard. Over the following days and weeks, your body fights back the only way it can: by making more red blood cells, the cells that carry oxygen from your lungs to your muscles. That process runs on iron, good circulation, and steady cellular energy. AltiFuel3 ES was formulated to support all three.
Clams are the ingredient that sets this formula apart. Most people know littlenecks from clam chowder and nothing else. What most menus never mention is that clams are one of the best natural sources of heme iron.
Where it comes from. Ours are littlenecks, raised in seawater pools beside the open ocean. They grow naturally until harvest, with no antibiotics at any point.
What it does in the body. Iron is the one ingredient your body cannot skip when it builds red blood cells. It sits at the heart of hemoglobin and powers erythropoiesis, the process that makes new red blood cells. Clams deliver plenty. A 3-ounce serving can provide up to 24 mg of iron, about three times the recommended daily amount, and much of it is heme iron, which your body absorbs much better than iron from plants or standard tablets. That absorption edge is the difference between a clean baton pass and one you have to chase down. Research also suggests iron is involved in the way cells sense oxygen, which may help muscle and tissue make use of the oxygen already available. One study associated iron supplementation with up to 65 percent fewer acute mountain sickness symptoms. Clams also provide B12, another nutrient involved in red blood cell formation.
Why it matters to you. Here is where AltiFuel3 ES separates from the liver version. Clams contain more iron than desiccated liver, giving this formula stronger blood oxygen support at altitude. That difference earned it the Highest Octane label. The higher you go, the less oxygen each breath gives you, and the more that extra iron support matters.
Cordyceps handles the energy side of the formula. Muscles demand just as much fuel at altitude as they do at sea level, and researchers have studied cordyceps for both energy support and tolerance to low-oxygen conditions.
Where it comes from. Centuries ago, herdsmen on the Tibetan plateau noticed that cattle grazing certain pastures came back with unusual stamina. The fungus growing in those pastures was cordyceps, and it has been part of traditional practice ever since. The world took notice in 1993, when the Chinese women’s track and field team broke nine world records at their National Games and cordyceps turned out to be part of the athletes’ training diet.
What it does in the body. In the studies cited here, cordyceps increased hypoxia tolerance and improved stamina and red blood cell production (5, 6). Other research points to antioxidant effects and protection of proteins and lipids from cellular damage. For athletes, the practical point is ATP. Every contraction spends ATP, and cordyceps supports the body’s ability to keep making it.
Why it matters to you. Thin air means less oxygen, but nobody shortens the race because the air gets thin. Your muscles still have the same work to do. Cordyceps is in the formula to support your energy while your body adjusts.
Ginkgo is here for circulation. Oxygen in your blood only helps if it reaches your muscles. That takes healthy blood flow, and ginkgo supports the blood vessel relaxation that helps keep blood moving.
Where it comes from. Ginkgo is one of the oldest tree species on Earth, and its leaf extract is one of the most researched botanicals in the world.
What it does in the body. In studies, ginkgo extract and its quercetin component relaxed blood vessel walls, and the effect grew with the dose. That response works through calcium and nitric oxide. Nitric oxide is the body’s natural vasodilator, the same compound your body releases during hard exercise. Ginkgo has also been studied at altitude for its antioxidant activity and its effects on blood flow.
Why it matters to you. Extra red blood cells help only when their oxygen arrives where it is needed. Ginkgo is in the formula to support that delivery.
Rhodiola is for the adjustment period. The first days at altitude feel a bit like the first week of preseason: the fitness is there, but everything is harder until your body finds its rhythm. Rhodiola supports nervous system balance and lung comfort through those first days.
Where it comes from. Rhodiola crenulata grows high in the mountains of Asia, where few other plants survive. Mountain communities there have used it for centuries.
What it does in the body. Researchers gave subjects Rhodiola crenulata together with cordyceps after high-altitude training and found they kept more stamina during exhaustive exercise. They traced the result to better parasympathetic nervous system activity and a smoother adjustment. Rhodiola has also been studied for its effects on free radicals and oxidative stress. In animal research, it reduced water buildup in the lungs and helped keep blood circulating through capillaries in low-oxygen conditions.
Why it matters to you. Those early days set the tone for the whole trip. Rhodiola is here for exactly that stretch.
Follow the oxygen and the formula explains itself. Clams provide the heme iron and B12 that build red blood cells, the carriers. Ginkgo supports the circulation that delivers them to working muscle. Cordyceps supports the energy systems that put the oxygen to use. Rhodiola steadies the body while it adjusts to elevation. Each ingredient has its own job, and together they work synergistically to meet the demands of performing at altitude. No supplement replaces a gradual, sensible ascent.
One important usage note: this is the Highest Octane AltiFuel. Use less at lower altitudes. It was formulated for elevation, and the full directions are on the label.
