B Excellence covers the basics of wellness with a balanced complex of all eight B vitamins in their most active, methylated form. The B vitamins are equal opportunity nutrients, helping the body metabolize energy, boost immune defenses, regulate cognitive function, handle stress, and protect from disease. Supplementing with bioavailable B vitamins is important for everyone, especially individuals who have to handle a lot of mental and physical stress on a daily basis.*
Poliquin products are now labeled PQN. Same formulas. Same quality. New name.
Product Updated: The updated formula delivers the same potency as the original—2 capsules now equal the strength of 1 capsule from the previous version.
B Excellence provides eight easily absorbed B vitamins plus trimethylglycine (TMG) in one capsule for a simple way to promote energy production, neurological function, and methylation.* This product features all the B vitamins in pharmacological doses with ample Pantothenic Acid (B5), making it is well suited for people who have to handle high levels of chronic stress.*
About Methylation
In simple terms, methylation protects your DNA, which is necessary for health. When mutations occur in DNA, your risk of disease, such as cancer, increases. Methylated B vitamins, including methylcobalamin (B12) and methylfolate (B9) help protect DNA by donating their methyl groups to cytosine, one of the four nucleic acids that make up DNA.
Methylation also helps the body detoxify homocysteine, an amino acid that is associated with heart disease. Methylation plays a role in synthesis of neurotransmitters, such as serotonin and norepinephrine, and hormones, including melatonin an estrogen. It also regulates the fight-or-flight stress response and impacts the function of immune cells.
B Excellence provides methylated tissue-ready B vitamins to ensure methylation processes are cranking.* About 40 percent of the population has the MTHFR genetic mutation that impairs their ability to convert the non-active B vitamins to their active forms. This increases risk of heart disease, migraines, miscarriages, Alzheimer’s, depression, mental illness, cancer, and autoimmune disease, such as lupus and rheumatoid arthritis. Other factors that can inhibit the body’s ability to convert non-active vitamins to their active forms include aging, compromised liver function, poorly functioning enzymes, digestive disturbances, and poor quality diet.
