MCHC (mean corpuscular hemoglobin concentration) measures the average concentration of hemoglobin within a given volume of red blood cells. This marker reflects how densely each red blood cell is packed with hemoglobin, the protein that carries oxygen. MCHC is used to classify anemias and assess the quality of hemoglobin loading in red blood cell production (source).
Low MCHC indicates each red blood cell carries a lower concentration of hemoglobin than optimal. This is most commonly driven by iron deficiency, which limits hemoglobin synthesis during red blood cell production in the bone marrow and spleen (source).
Potential Performance Impact:
Prioritize iron-rich foods: Low iron levels are associated with low MCHC (source). Iron is a key component of hemoglobin; increased iron intake provides the raw material for hemoglobin synthesis, increasing MCHC (source).
Protocol: Consume at least two servings of iron-rich foods weekly. Examples: Liver (3 oz), Oysters (3 oz), Lentils (1 cup), Pumpkin Seeds (1 oz)
Supplement with spirulina: Spirulina supplementation has been shown to increase MCHC (source). Spirulina contains a high concentration of bioavailable iron that increases hemoglobin synthesis, raising MCHC (source).
Protocol: Supplement with at least 1 g of spirulina daily.
Elevated MCHC indicates red blood cells carry a higher-than-normal hemoglobin concentration, often driven by factors affecting red blood cell production in the bone marrow and spleen. Vitamin B12 and folate status can influence MCHC levels (source).
Potential Performance Impact:
Incorporate matcha tea: Matcha tea consumption has been shown to decrease MCHC levels (source). Matcha contains tannins, primarily EGCG, that reduce iron absorption, potentially decreasing hemoglobin concentration and MCHC (source, source).
Protocol: Consume at least 2 g of matcha tea daily, steeped in hot water.
Resistance training: Resistance training has been shown to decrease MCHC (source). Resistance training increases plasma blood volume, which dilutes hemoglobin concentration in red blood cells and lowers MCHC (source).
Protocol: Follow a structured resistance training program with moderate to heavy loads at least twice per week. The final set of each exercise should be taken within two repetitions of failure.
Supplement with a vitamin B complex: High MCHC is associated with B vitamin deficiency (source). B vitamins encourage cell division and maturation in the bone marrow, maintaining regular hemoglobin concentrations and MCHC levels (source).
Protocol: Supplement with a vitamin B complex that has at least 50% of daily recommendations for each B vitamin.
