Name and Basic Overview

NOW Foods Ultra B-12 is a dietary supplement designed to provide a high dose of Vitamin B-12, along with a complete B-complex in liquid form. It contains 5,000 mcg of B-12 per teaspoon, aimed at boosting cellular energy.

Vitamin B-12 is naturally found in animal products such as meat, fish, and dairy, but this supplement is suitable for vegetarians and vegans as it is non-animal derived.

People commonly seek Vitamin B-12 supplements for energy enhancement, support of brain and nervous system function, and to prevent deficiency, especially in those with dietary restrictions.

Historical Background / Traditional Use

Vitamin B-12 was first isolated in the 1940s, and its deficiency was linked to pernicious anemia, a condition previously treated with liver extracts.

Historically, B-12 was not recognized in traditional medicine systems due to its discovery in the 20th century. Modern usage focuses on supplementation for those at risk of deficiency, such as vegans and the elderly.

Composition and Active Components

The supplement contains three forms of Vitamin B-12: Cyanocobalamin, Methylcobalamin, and Dibencozide, which are utilized differently by the body to support various physiological functions.

It also includes other B vitamins: Thiamine (B-1), Riboflavin (B-2), Niacin (B-3), Vitamin B-6, Folate, Biotin, and Pantothenic Acid (B-5), each playing roles in energy metabolism, red blood cell formation, and nervous system health.

Research and Evidence Base

Clinical studies have shown that Vitamin B-12 is crucial for neurological function and red blood cell production. Deficiency can lead to anemia and neurological issues.

Research supports the use of B-12 supplements in individuals with dietary restrictions or absorption issues, such as those with pernicious anemia or gastrointestinal disorders.

Evidence for the efficacy of B-12 in energy enhancement is mixed, with some studies suggesting benefits in individuals with deficiency, while others show limited effects in those with adequate levels.

The inclusion of multiple B vitamins in the supplement is supported by evidence indicating their synergistic role in energy metabolism and overall health, though more research is needed to fully understand the benefits of high-dose B-complex supplementation.

Potential Health Benefits

• Supports Energy Production: The high dose of Vitamin B-12 (5,000 mcg per teaspoon) is marketed to boost cellular energy, which is crucial for individuals experiencing fatigue or low energy levels. B-12 plays a vital role in converting food into energy.
• Nervous System Health: Vitamin B-12 is essential for maintaining the health of nerve cells and supporting the normal functioning of the brain and nervous system.
• Red Blood Cell Formation: Adequate B-12 levels are necessary for the production of red blood cells, which can help prevent anemia.
• Homocysteine Metabolism: The inclusion of folic acid (800 mcg) and other B vitamins supports the metabolism of homocysteine, potentially reducing cardiovascular risk.
• Vegan and Vegetarian Friendly: This supplement is suitable for vegetarians and vegans, who are at a higher risk of B-12 deficiency due to dietary restrictions.

Safety, Side Effects, and Precautions

• Gastrointestinal Upset: Some individuals may experience mild gastrointestinal issues, such as nausea or diarrhea, when taking high doses of B-12.
• Allergic Reactions: Although rare, allergic reactions to B-12 supplements can occur. Symptoms may include itching, rash, or swelling.
