insights Analysis
This Swanson Ultra product combines a moderate dose of Vitamin B12 (cyanocobalamin) with Folic Acid, which is beneficial as these two vitamins work synergistically in many metabolic pathways, including those crucial for energy and cognitive function. However, the use of cyanocobalamin and likely folic acid (rather than more bioavailable methyl forms) means the body needs to convert them, which can be inefficient for some individuals, particularly those with MTHFR gene variations. Its low price point makes it an accessible option, but its effectiveness for individuals with impaired conversion might be limited.
- Very affordable price per serving.
- Combines B12 with Folic Acid, supporting synergistic functions.
- Widely available and popular.
- Uses cyanocobalamin, a synthetic form requiring conversion.
- Uses Folic Acid, which is less bioavailable than methylfolate for some individuals.
- Capsule form may have slower absorption compared to sublinguals or liquids.
- Individuals with MTHFR gene mutations may not effectively utilize the folic acid and cyanocobalamin forms; it's advisable for such individuals to seek supplements with methylfolate and methylcobalamin.

bolt Effectiveness for goals
Vitamin B12 is crucial for red blood cell formation, DNA synthesis, and proper neurological function. It helps maintain the health of nerve cells and supports the metabolism of every cell in the human body. Adequate intake is essential for overall health and well-being.
Vitamin B12 is vital for cellular energy production. However, supplementation primarily increases energy in individuals who are deficient in Vitamin B12. For those with adequate levels, there is limited evidence to suggest it provides an additional energy boost.
Vitamin B12 supplementation is highly effective in treating and preventing B12 deficiency. It can reverse many deficiency symptoms, such as anemia and neurological issues, especially when started promptly. The specific form and dosage depend on the individual's condition and the cause of the deficiency.
Vitamin B12 plays an important role in brain health and nerve function. In individuals with a B12 deficiency, supplementation can improve memory and cognitive issues. However, for people with sufficient B12 levels, there is limited evidence that supplements enhance cognitive abilities.
Yes, Vitamin B12 is essential for maintaining the myelin sheath that protects nerves and for synthesizing neurotransmitters. Deficiency can lead to neurological damage, including tingling, numbness, and difficulty with coordination. Supplementation helps prevent or reverse these issues in deficient individuals.
schedule Dosage, timing & forms
The recommended daily allowance (RDA) for adults is 2.4 mcg, but supplemental dosages can vary widely. For addressing deficiencies or maintaining levels in specific populations, daily dosages often range from 250 mcg to 1000 mcg or more. Higher doses are generally well-tolerated due to B12's low toxicity.
Vitamin B12 supplements are commonly available as cyanocobalamin, methylcobalamin, adenosylcobalamin, and hydroxocobalamin. Cyanocobalamin is a synthetic form, while methylcobalamin and adenosylcobalamin are natural, active forms found in the body. The choice of form may depend on individual needs or preferences.
Vitamin B12 is a water-soluble vitamin, meaning that excess amounts are generally excreted in the urine, making toxicity rare. No Upper Tolerable Intake Level (UL) has been established for Vitamin B12 due to its extremely low potential for harm. However, it is always advisable to follow recommended dosages or consult with a healthcare provider for very high doses.
There is no universally 'best' time to take Vitamin B12, as it can be taken effectively at any time of day. Some suggest taking it in the morning on an empty stomach for optimal absorption, while others find taking it with food helps prevent minor stomach upset. Consistency in taking the supplement is generally more important than the specific timing.
Yes, specific populations often have different Vitamin B12 requirements or dosage recommendations. Vegetarians and vegans, for example, typically require supplementation due to the lack of dietary B12 sources. Older adults and individuals with certain gastrointestinal conditions may also need higher doses due to age-related malabsorption or specific medical conditions.
health_and_safety Safety & interactions
Yes, certain medications can interact with Vitamin B12 absorption or metabolism. These include metformin, proton pump inhibitors (PPIs), H2-receptor antagonists, and some antibiotics. Individuals taking such medications should discuss B12 supplementation with their healthcare provider.
Vitamin B12 is generally considered safe, even at higher doses, because it is a water-soluble vitamin. Excess amounts are typically excreted through urine, minimizing accumulation. However, it is always advisable to consult a healthcare professional before starting any new supplement.
Side effects from Vitamin B12 supplementation are rare, especially with oral forms. Mild gastrointestinal upset or skin reactions have been reported in some individuals. Serious adverse effects are highly uncommon.
Vitamin B12 has a low potential for toxicity because it is a water-soluble vitamin. There is no established upper intake level, as excess amounts are generally excreted without adverse effects. However, extremely high doses without medical supervision are not typically recommended.
Adequate Vitamin B12 is crucial for maternal and infant health during pregnancy and breastfeeding. Supplementation is generally considered safe and is often recommended, particularly for individuals with dietary restrictions. Discuss appropriate dosages with a healthcare professional.

Vitamin B12 68.0
As a Vitamin B12 product, its score is lowered by the use of cyanocobalamin, which is not the most bioavailable form, despite the synergistic inclusion of folate. Better B12 forms are available in alternatives.
Goals
Metabolism Boost 75.0
B12 and folate are both essential for metabolic processes. While cyanocobalamin and folic acid are functional, the body's conversion steps mean the 'boost' might not be as immediate or potent as with activated forms.
Energy 70.0
While 1000 mcg of cyanocobalamin can contribute to energy, its synthetic nature means it needs conversion, which can slow down or reduce its energizing effects compared to methylcobalamin. The inclusion of folic acid is synergistic but also in a less preferred form.
Brain Health 70.0
Both B12 and Folate are vital for neurological health. However, the cyanocobalamin and folic acid forms are less directly utilized by the brain compared to their methylated counterparts, potentially making it less effective for optimal brain health support.
