MANY PEOPLE NEED A B6 SUPPLEMENT - Your body doesn’t produce vitamin B6, so you have to get it from foods like eggs, brewer’s yeast, carrots, chicken, fish, brown rice, whole grains and cabbage. If you don’t eat enough of these foods, you should choose a high-quality supplement—because B6 is really, really good for you.

CARDIOVASCULAR HEALTH – There’s an amino acid called homocysteine that’s a well-known marker for both heart and brain health. Maintaining homocysteine levels already within normal range is good for your cardiovascular system and your circulatory health. Vitamin B6 helps maintain already-healthy homocysteine levels...which keeps your blood flowing freely!

IMMUNE HEALTH, MOOD & MORE – Vitamin B6 helps encourage a healthy immune response, so you’re ready for what the world throws at you. And because your body uses vitamin B6 to make the neurotransmitter serotonin, this essential vitamin helps support a better mood. And because of its aforementioned effect on homocysteine, vitamin B6 promotes brain health, too.
