Premier Research Labs Max B-ND is a high-potency, probiotic-fermented liquid B-complex designed to support energy production, stress resilience, and overall cellular health. Unlike most synthetic B vitamins, Max B-ND is made using proprietary probiotic fermentation, providing naturally sourced, highly bioavailable B vitamins for optimal absorption. This advanced formula provides active, end-chain forms of B vitamins—including methylated B12, 5-MTHF folate, and coenzyme forms such as riboflavin-5-phosphate and pyridoxal-5-phosphate—alongside supportive nutrients like amino acids, glutathione, and beta glucans. Together, these nutrients help nourish the nervous system, support adrenal and liver function, and promote brain clarity, mood balance, cardiovascular health, and healthy aging, making it especially beneficial for individuals experiencing fatigue, stress, or increased nutritional demands.
