Science-based nutrition. Dietary supplement. Helps maintain healthy cells in the presence of blood glucose. Controls formation of Advanced Glycation Endproducts (AGEs). Normalizes cellular processes fueled by glucose metabolites. Benfotiamine (S-benzoylthiamine-O-monophosphate) is a synthetic derivative of thiamin, belonging to the family of compounds knows as "allithiamines." Benfotiamine is fat-soluble and more bioavailable and physiologically active than thiamin. Benfotiamine raises the blood level of thiamin pyrophosphate (TPP), the biologically active co-enzyme of thiamin, and stimulates transketolase, a cellular enzyme essential for maintenance of normal glucose metabolic pathways.

The use of bromelain has foundations in folk medicine, as Ananas comosus was used by the aboriginal inhabitants of Central and South America for various facets of health promotion. A 17th century explorer from Europe noted that the extract from the plant "admirably recreates and exhilarates the Spirits and comforts the Heart." 1Bromelain is renowned for its protein digesting (protease) activity. The ability of the thiol-endopeptidase enzymes in bromelain to break down proteins leads to bromelain's most noted health-promoting properties. The enzymatic activity of bromelain is measured by its ability to digest various substrates. GDU, or gelatin-digesting units, are a common measure of bromelain's potency. Doctor's Best currently has the highest potency bromelain available on the market. Bromelain is known for its enzymatic and immune-modulating activities as well as its contributions to joint health maintenance and healthy circulation. Best 3000 GDU Bromelain is a proteolytic enzyme that supports healthy immune function.*Bromelain has the ability to activate various immune cells and their cytokines.2 Cytokines are signaling molecules secreted by immune cells that act as messengers to alert other immune cells. In vitro trials have shown that bromelain can alter immune cell secretion of cytokines in a way that would be favorable for maintaining balance in the human immune system.3 There is also in vitro evidence that bromelain can alter T cell signal transduction,

These substances are known to be powerful free radical scavengers.*Best Acai contains a potent certified-organic freeze-dried form of acai fruit. Most 4:1 acai products are spray-dried powder extracts which contain significant amounts of maltodextrin and are much lower in nutritional content compared to the Doctor's Best certified organic freezedried acai powder.Because the spray drying process causes a loss of nutritional value, many of the compounds needed for beneficial free radical scavenging effects are destroyed. These compounds are volatile and susceptible to destruction over time, if not preserved. In contrast, the process of freeze-drying helps to strongly preserve the antioxidant compounds in the fruit since it is done at low temperature and immediately after harvesting the berries. This process in fact concentrates the beneficial compounds in acai berries by removing only the moisture content fr

Acetyl-L-Carnitine (ALC) is a naturally occurring form of L-Carnitine, a vitamin-like nutrient synthesized in the body from the amino acids lysine and methionine. ALC serves as a transport molecule for "active acetate," which is a source of fuel for metabolic processes that take place in cells. ALC carries active acetate (the "Acetyl" portion) directly into the mitochondrion, the cell's energy-generating structure. Active acetate is used to produce cellular energy in the form of ATP. Both L-Carnitine and ALC serve as fat carriers. Unlike L-Carnitine, ALC readily crosses the blood-brain barrier, where it has specific benefits for brain neurons. When taken orally, ALC has been shown to increase ALC levels in both blood and cerebrospinal fluid, demonstrating its uptake in the brain.Best Acetyl-L-Carnitine consists of Biosint?Acetyl-L-Carnitine, which is manufactured in Italy by the Sigma Tau company. It is derived from a base of pharmaceutical-grade L-Carnitine manufactured using an FDA-approved process that fully complies with international monograph standards for carnitine production. Known as a global leader in L-Carnitine research, Sigma Tau holds numerous patents for production of L-Carnitine, and its L-Carnitine derivatives, such as ALC, which are used in clinical trials.BenefitsSupports cognitive function* ALC has been studied for its effect on cognitive performance and emotional health in the elderly. In a single-blind, placebo-controlled trial, 481 elderly subjects exhibiting mild memory impairment improved their scores on a memory test after taking 1500 mg of ALC a day for 90 days. Hospitalized elderly people taking ALC have shown improvements in mental outlook.While ALC is not a treatment or cure for Alzheimer's disease, double-blind studies suggest it may help slow the rate at which early-stage Alzheimer's patients deteriorate. In particular, ALC seems to benefit short-term memory in these patients.Supports biosynthesis of acetylcholine, a key neurotransmitter for brain and nerve function*Brain function requires coordinated communication between brain cells. Brain and nerve cells ("neurons") communicate across tiny cell-to-cell gaps called "synapses." The passage of an electrical impulse from one neuron to the next requires a "neurotransmitter." When an electrical signal arrives at the synaptic junction, the neuron releases a neurotransmitter into the synapse. The neuron on the other side of the synapse contains receptors for the neurotransmitter; these receptors bind the neurotransmitter, triggering a series of chemical events that sends a new electrical signal down the membrane of the receiving neuron. Neurotransmitters work together like an orchestra to transmit information throughout the brain and nervous system. Acetylcholine is the most abundant neurotransmitter in the body, regulating activities of vital organs, blood vessels and communication between nerves and muscles.
