Vitamin B6 (pyridoxine HCl, pyridoxal-5-phosphate)

Vitamin B6 acts as a coenzyme in amino acid metabolism and neurotransmitter synthesis, which may support energy production and nervous system function.

Caution: High-dose B6 over time may cause tingling or numbness in extremities; stop use if these symptoms appear.

Riboflavin (vitamin B2, including riboflavin-5-phosphate)

Riboflavin helps form FAD and FMN, coenzymes involved in cellular energy production and antioxidant enzyme activity.

Caution: May cause bright yellow urine, which is harmless.

Niacin (as niacinamide)

Niacinamide supports the formation of NAD and NADP, coenzymes essential for energy metabolism and cellular repair.

Caution: Less likely to cause skin flushing than niacin, but high doses may upset the stomach when taken on an empty stomach.

Pantothenic Acid (vitamin B5, as D-Ca pantothenate and pantethine)

Pantothenic acid supports coenzyme A production, which is central to fatty acid metabolism and energy generation.

Caution: Large doses may cause mild gastrointestinal discomfort in some people.

Folate (400 mcg folic acid, 666 mcg DFE)

Folate supports one‑carbon metabolism for DNA synthesis and methylation, which is important for cell division.

Caution: Folic acid may mask signs of low vitamin B12; suitable B12 intake is important.

How they work together

These B vitamins serve as coenzymes in different steps of carbohydrate, fat, and protein metabolism, collectively supporting cellular energy production. Folate contributes to one‑carbon transfer reactions for DNA synthesis while B6 and niacinamide drive amino acid and redox pathways, and riboflavin and pantothenic acid help shuttle electrons and acetyl groups within energy cycles.

Label Warning: If you are pregnant, nursing, taking any medications, have a medical condition, or plan clinical lab testing, consult a healthcare practitioner before use. Some supplements may interact with medications or interfere with lab tests. If adverse reactions occur, stop use and consult a healthcare practitioner.

Who should be cautious: People with soy allergy should use caution due to soy lecithin. Those undergoing lab testing may want to check for possible biotin interference, even though the amount here is low. People on medications or with medical conditions should discuss with a healthcare provider before use.

Storage: Store at room temperature.

Noticeable energy and focus support

Many customers mention increased energy and clearer mental focus after regular use.
