EPO tells your bone marrow to produce more red blood cells; more red blood cells raise your <strong>hematocrit<\/strong> (the percentage of your blood that is red cells) and your <strong>hemoglobin<\/strong>, and more hemoglobin means more oxygen reaching working muscle.<\/p>\n<p>Synthetic EPO is a banned drug. A <strong>natural EPO supplement<\/strong> does something completely different: it supplies the plant extracts shown to activate your own EPO-producing kidney cells, together with every nutrient the bone marrow needs to actually build the new red blood cells. Blood Booster Active\u00b9\u2077 does both \u2014 and adds a third layer that lets the extra oxygen translate into performance.<\/p>\n<p>In SCN\u2122 athlete monitoring, this approach increased natural EPO production by 350\u2013480% and hematocrit by 4.1\u20137.4%, with effects persisting 40\u201350 days after the cycle ended.<\/p>\n<\/p><\/div>\n<figure>\n      <img decoding=\"async\" src=\"https:\/\/www.s-c-nutrition.com\/wp-content\/uploads\/2017\/08\/slide_16-768x576.jpg\" alt=\"How a natural EPO supplement works: kidneys release erythropoietin, bone marrow makes red blood cells, hematocrit rises\" title=\"Erythropoietin pathway \u2013 Blood Booster Active\u00b9\u2077 by SCN\u2122\" loading=\"lazy\"><figcaption>Kidney \u2192 erythropoietin \u2192 bone marrow \u2192 red blood cells \u2192 hematocrit \u2192 oxygen delivery<\/figcaption><\/figure>\n<\/p><\/div>\n<div class=\"steps\" style=\"margin-top:2rem\">\n<div class=\"step\">\n<h3>Stimulate \u2014 activate your own EPO<\/h3>\n<p>A 7,050 mg double-Echinacea complex (<em>Echinacea purpurea<\/em> + <em>Echinacea angustifolia<\/em>, both standardised to 4% echinacosides) uses two different gut transporters for synergistic absorption.

Echinacea extract is the botanical shown to activate the specialised kidney cells that produce erythropoietin. We use two species, both standardised to 4% echinacosides (280 mg total echinacosides per day), because they are absorbed through different transporters in the gut wall \u2014 so the two extracts work synergistically rather than competing. Echinacea also supports normal immune function, which matters in heavy training blocks when upper-respiratory issues typically derail athletes.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Cordyceps dry extract 50:1, 15% cordycepic acid <span class=\"dose\">1,750 mg<\/span><\/h4>\n<p>The highest-concentration cordyceps extract on the market, at a dose 200% higher than our previous formula. Most brands use plain mushroom powder (look for the word &#8220;extract&#8221; on any label) or 4\u20135% extracts. Cordyceps supports oxygen utilisation in the blood, ATP production and energy metabolism, and has a long history of use for stamina and respiratory capacity \u2014 exactly the properties an endurance athlete wants once the extra red blood cells are in circulation.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Vitamin C <span class=\"dose\">1,750 mg \u00b7 2188% NRV<\/span><\/h4>\n<p>Up 220% versus the previous formula. Vitamin C increases iron absorption in the gut and helps the body store iron \u2014 the single most important cofactor for making the Lipofer\u2122 iron in the formula count. It also contributes to normal collagen formation for blood vessels, normal immune function during and after intense exercise, protection of cells from oxidative stress and reduction of tiredness and fatigue.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Fructooligosaccharides (FOS) <span class=\"dose\">875 mg<\/span><\/h4>\n<p>A prebiotic fibre that feeds beneficial gut bacteria. A healthier gut environment supports mineral absorption \u2014 including iron and zinc \u2014 and helps the formula sit comfortably in the stomach twice a day for 40 days.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Pantothenic acid (vitamin B5) <span class=\"dose\">323.75 mg \u00b7 5396% NRV<\/span><\/h4>\n<p>Vitamin B5 contributes to normal energy-yielding metabolism, normal mental performance, reduction of tiredness and fatigue, and the normal synthesis and metabolism of steroid hormones, vitamin D and some neurotransmitters. It is also central to coenzyme A \u2014 the molecule every fuel source passes through on its way to becoming ATP.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Niacin \u2014 nicotinamide + nicotinic acid (vitamin B3) <span class=\"dose\">262.5 mg NE + 8.75 mg NE<\/span><\/h4>\n<p>Two forms of vitamin B3. The coenzymes NAD and NADP, made from niacin, are required by up to 200 enzymes to carry electrons in the redox reactions that release energy from carbohydrate, fat and protein. Niacin contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function, maintenance of normal skin and mucous membranes, and reduction of tiredness and fatigue. The small nicotinic acid fraction also supports normal blood flow.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Rhodiola rosea \u2014 two extracts (10% rosavins; 6% rosavins \/ 3% salidroside) <span class=\"dose\">175 mg + 87.5 mg<\/span><\/h4>\n<p>Rhodiola is the adaptogen of choice for endurance. Two standardised extracts give the full spectrum of both rosavins and salidroside, the two active families. Taken 30\u201345 minutes before training, rhodiola supports endurance and exercise performance, a lower heart rate at a given intensity, faster lactate clearance after exhaustive effort, and lower markers of exercise-induced muscle damage. It also supports perceived exertion \u2014 you feel and breathe better at pace \u2014 plus antioxidant, cognitive and mood support off the bike or track.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Lipofer\u2122 microencapsulated liposomal iron <span class=\"dose\">87.5 mg \u00b7 7.53 mg iron \u00b7 53% NRV<\/span><\/h4>\n<p>Iron is the heart of every hemoglobin molecule \u2014 no iron, no new red blood cells, however much EPO your kidneys release. Lipofer\u2122 (from Lipofoods) is iron wrapped in a microencapsulated liposomal carrier that bypasses the gut irritation and poor absorption of standard iron salts and delivers iron straight into the cells that need it, with far higher bioavailability than conventional forms. In clinical work, Lipofer\u2122 raised serum ferritin by 30% within 4 weeks and 80% within 16 weeks. Iron contributes to normal formation of red blood cells and hemoglobin, normal oxygen transport, normal energy-yielding metabolism, normal cognitive function and reduction of tiredness and fatigue.

Muscle tissue accumulates senescent cells \u2014 cells that stop dividing but refuse to die \u2014 and the higher their density, the worse the tissue performs. Senactiv\u00ae activates macrophages to clear senescent cells and allows stem cells to migrate into exercised muscle for new muscle cell generation. Younger muscle cells carry more mitochondria, produce more ATP and store more glycogen. In studies Senactiv\u00ae increased endurance via improved glycogen replenishment and citrate synthase activity, and sped recovery by lowering exercise-induced inflammation (TBARS, MDA, IL-6, CK, TNF-\u03b1) and accelerating regeneration (Pax7, Myf5, centrally nucleated myofibres). It is also the ingredient that makes Blood Booster Active\u00b9\u2077 relevant to healthy ageing and masters athletes.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Vitamin B1 (thiamine HCl) <span class=\"dose\">61.25 mg \u00b7 5568% NRV<\/span><\/h4>\n<p>Thiamine pyrophosphate is the coenzyme that lets pyruvate enter the mitochondria as acetyl-CoA \u2014 the gateway between glycolysis and aerobic energy. Vitamin B1 contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function and normal function of the heart, which holds a high concentration of thiamine.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Zincnova\u2122 microencapsulated liposomal zinc <span class=\"dose\">26.25 mg \u00b7 5.25 mg zinc \u00b7 52.5% NRV<\/span><\/h4>\n<p>Zinc sits inside hundreds of enzymes. Zincnova\u2122 is a non-reactive zinc microencapsulated in a food-grade lipid carrier that protects it from interacting with other ingredients, preserving bioavailability. Zinc contributes to normal immune function, normal cognitive function, normal protein synthesis, normal testosterone levels in the blood, maintenance of normal bones and vision, and protection of cells from oxidative stress. In trained athletes, zinc supplementation has been associated with improved muscle strength and endurance. Want the full-dose version? See <a href=\"https:\/\/www.s-c-nutrition.com\/product\/zinc-liposmal\/\" data-wpel-link=\"external\" rel=\"noopener\">LipoZinc\u00b9\u00b2\u2075<\/a>.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Vitamin B6 (pyridoxal-5\u2032-phosphate, P5P) <span class=\"dose\">12 mg \u00b7 857% NRV<\/span><\/h4>\n<p>The already-active coenzyme form of B6 \u2014 no liver conversion required. P5P contributes to normal red blood cell formation, normal protein and glycogen metabolism, normal energy-yielding metabolism, normal homocysteine metabolism, normal cysteine synthesis, normal functioning of the nervous system and psychological function (it is required to make dopamine, noradrenaline, serotonin and GABA), normal immune function, regulation of hormonal activity and reduction of tiredness and fatigue.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Vitamin B12 (methylcobalamin) <span class=\"dose\">175 \u00b5g \u00b7 7000% NRV<\/span><\/h4>\n<p>Methylcobalamin is the most bioavailable, body-ready form of the &#8220;blood vitamin&#8221;. Vitamin B12 contributes to normal red blood cell formation, normal energy-yielding metabolism, normal homocysteine metabolism, normal functioning of the nervous system, normal psychological function, normal immune function and reduction of tiredness and fatigue. Without adequate B12 and folate, red blood cells grow large and immature \u2014 a classic cause of unexplained fatigue in endurance athletes.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Vitamin B2 (riboflavin) <span class=\"dose\">17.5 mg \u00b7 1250% NRV<\/span><\/h4>\n<p>Riboflavin is required for hemoglobin synthesis and for mobilising stored iron from ferritin \u2014 iron metabolism is impaired without it. In its coenzyme forms FAD and FMN it drives the citric acid cycle. Vitamin B2 contributes to maintenance of normal red blood cells, normal metabolism of iron, normal energy-yielding metabolism, normal functioning of the nervous system, maintenance of normal vision, skin and mucous membranes, protection of cells from oxidative stress and reduction of tiredness and fatigue.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Biotin (vitamin B7) <span class=\"dose\">17,500 \u00b5g \u00b7 35000% NRV<\/span><\/h4>\n<p>Biotin is the cofactor for five carboxylase enzymes, including pyruvate carboxylase (making glucose from non-carbohydrate sources, vital in long events) and acetyl-CoA carboxylase (fatty-acid metabolism). It contributes to normal energy-yielding metabolism, normal macronutrient metabolism, normal functioning of the nervous system, normal psychological function and maintenance of normal hair, skin and mucous membranes.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>BioPerine\u00ae \u2014 black pepper extract 95% piperine <span class=\"dose\">17.5 mg \u00b7 16.6 mg piperine<\/span><\/h4>\n<p>Patented piperine extract that increases the absorption of many nutrients and botanicals by slowing their breakdown in the gut and liver. In a formula this dense, BioPerine\u00ae makes sure the vitamins, minerals and herbal actives actually reach the bloodstream.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Copper <span class=\"dose\">0.73 mg \u00b7 73% NRV<\/span><\/h4>\n<p>The forgotten blood mineral. Copper is needed for ceruloplasmin, the enzyme that lets iron be released from storage and loaded onto transferrin for transport to the bone marrow \u2014 without copper, iron is stuck. Copper contributes to normal iron transport, normal energy-yielding metabolism, normal immune function, normal functioning of the nervous system and protection of cells from oxidative stress.<\/p>\n<\/p><\/div>\n<div class=\"ing\">\n<h4>Folate <span class=\"dose\">875 \u00b5g \u00b7 438% NRV<\/span><\/h4>\n<p>Folate partners with B12 in DNA synthesis \u2014 the rate-limiting step when the bone marrow is dividing rapidly to produce new red blood cells. It contributes to normal blood formation, normal amino acid synthesis, normal homocysteine metabolism, normal psychological function, normal immune function, reduction of tiredness and fatigue and the process of cell division.<\/p>\n<\/p><\/div>\n<figure>\n    <img decoding=\"async\" src=\"https:\/\/www.s-c-nutrition.com\/wp-content\/uploads\/2019\/10\/blood_site_1.png\" alt=\"Blood Booster Active\u00b9\u2077 EPO supplement \u2013 erythropoiesis infographic showing red blood cell production\" title=\"Erythropoiesis \u2013 Blood Booster Active\u00b9\u2077 by SCN\u2122\" loading=\"lazy\"><figcaption>Erythropoiesis: from EPO signal to oxygen-carrying red blood cells<\/figcaption><\/figure>\n<\/section>\n<p><!-- ================= HOW TO USE ================= --><\/p>\n<section class=\"sec\">\n  <span class=\"eyebrow\">Suggested use<\/span><\/p>\n<h2>How to use Blood Booster Active\u00b9\u2077 \u2014 the 40-day cycle<\/h2>\n<div class=\"grid g2\" style=\"align-items:start\">\n<div>\n<ul class=\"check\">\n<li><strong>Daily dose:<\/strong> 2 servings per day = 14 g (4 scoops).

It contains no erythropoietin, no hormones and no prohibited substance, combination or derivative. Every ingredient is a natural extract, vitamin or mineral and the formula fully complies with the 2027 prohibited lists of all sports anti-doping agencies. It is safe to use in and out of competition and safe for doping control at any time.<\/p>\n<\/details>\n<details>\n<summary>How does a natural EPO supplement increase hematocrit?<\/summary>\n<p>It works on both ends of the process. Echinacea extracts stimulate the kidney cells that release your own erythropoietin, and bioavailable iron, B12, folate, B6, B2 and copper give the bone marrow the raw materials to build the red blood cells that EPO calls for. More red blood cells = higher hematocrit and hemoglobin = more oxygen to working muscle.<\/p>\n<\/details>\n<details>\n<summary>How long does it take to see results?<\/summary>\n<p>Red blood cells take roughly 3\u20134 weeks to mature, which is why the protocol is a 40-day cycle. Most athletes notice easier breathing and better repeatability within the first 2\u20133 weeks; blood-marker changes are typically visible by the end of the cycle. In SCN\u2122 monitoring, effects persisted 40\u201350 days after stopping.<\/p>\n<\/details>\n<details>\n<summary>Why two tubs?<\/summary>\n<p>One tub (280 g) is 20 days at the full 14 g daily dose \u2014 a Half Cycle. The recommended Full Cycle is 40 days, so two tubs. The 4-tub and 12-tub options give 20% and 25% off for athletes running back-to-back cycles through the season.<\/p>\n<\/details>\n<details>\n<summary>Can I take it with my other SCN\u2122 products?<\/summary>\n<p>Yes \u2014 it is designed as the foundation of the endurance stack. If you already take MicroIron, LipoZinc\u00b9\u00b2\u2075 or a multivitamin, check your total daily intake of iron and zinc and adjust as needed, or ask our team.<\/p>\n<\/details>\n<details>\n<summary>Does it contain caffeine or stimulants?<\/summary>\n<p>No. Blood Booster Active\u00b9\u2077 is stimulant-free. Its energy effect comes from improved oxygen delivery and mitochondrial energy production, not from central nervous system stimulation \u2014 so it will not affect sleep or heart rate at rest.<\/p>\n<\/details>\n<details>\n<summary>Who should not use it?<\/summary>\n<p>Food supplements should not replace a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. Not intended for children or during pregnancy or breastfeeding. If you take medication, have a medical condition, or your blood values are already outside the normal range, consult your physician before use.
