Doctor's Best 5-HTP Enhanced w/Vitamins B6 and C - 120 Vcaps
Science-based nutrition Dietary supplement Helps maintain mental & emotional well-being 5-HTP (5-hydroxy L-tryptophan) is a naturally-occurring metabolite of the amino acid tryptophan. 5-HTP is converted in the brain to serotonin, a neurotransmitter substance found at the junctions (synapses) between neurons. 5-HTP helps maintain mental and emotional well-being and promotes healthy sleep. Doctor's Best 5-HTP is extracted from the seeds of the Griffonia simplicifolia plant.As low as:$21.15 -
Doctor's Best Best Brain Magnesium 150 mg - 60 Vcaps
Science-based nutrition Dietary supplement Unique delivery of magnesium into the brain Vital for memory, learning, concentration Promotes stability and adaptability of brain connections (synapses) Best Brain Magnesium supplies magnesium l-threonate (Magtein), a unique magnesium compound for delivering magnesium to the brain. Magnesium is essential for the brain connections (synapses) that facilitate learning, memory, attention, and all other brain functions. The l-threonate salt extends the action of magnesium. In preclinical studies, Magtein performed better than other magnesium compounds for synapse support. Best Brain Magnesium is a breakthrough for brain health.As low as:$24.40 -
Doctor's Best Best D-Ribose - 250 Grams
Science-based nutrition Dietary supplement Supports healthy energy levels in heart and muscle tissue Maintains normal heart function Decreases free radical formation during exercise Ribose is an essential pentose (5-carbon) sugar utilized by the body to synthesize DNA, RNA and produce energy. Ribose is a fundamental building block of adenosine triphosphate (ATP – the substance in which the body stores intracellular energy), the preferential source of energy for skeletal muscle and heart tissue. Studies have shown that ribose supplementation can enhance cardiac energy levels and support cardiovascular metabolism. Further studies suggest that ribose plays a role in supporting energy recovery after exercise. Exercise increases free radical production in muscle tissue. Ribose may strengthen and support the body's crucial antioxidant defenses.As low as:$29.11 -
Doctor's Best Best Fucoidan 70% 300 mg - 60 Vcaps
Science-based nutrition Dietary supplement Enhances immune system function Potent antioxidant protection Best Fucoidan 70% contains the gluconutrient fucoidan derived from brown algae. Seaweeds are a part of the diet in many cultures and fucoidan-containing species have been used traditionally for a variety of therapeutic purposes. Fucoidan contains an abundance of immune-modulating constituents known as polysaccharides. These unique and complex sulfated polysaccharides are not found in other seaweeds or land plants, and have been shown to mediate a variety of significant biological effects on mammalian cells in laboratory research. Research also suggests that fucoidan may possess significant antioxidant activity.As low as:$27.71
