First choice for an increased need for vitamin B12

B12 Combi 6.000® combines high-dose vitamin B12 with Quatrefolic®. This combination is the core of the formula. If you have an increased need for vitamin B12, we recommend B12 Combi 6.000® with folate. We added folate and vitamin B6 to support vitamin B12 absorption.

Quatrefolic® is an award-nominated folate form

Quatrefolic® received recognition in several industry awards. Examples include the Most Effective Strategic Product Development Award. It also reached finalist positions for Best New Ingredient. It also reached finalist positions for Finished Product of the Year in the Medical Food category. Quatrefolic® is a leading folate form worldwide.

High-dose vitamin B12

B12 Combi 6.000® with folate and P-5-P contains two active forms of vitamin B12. It contains adenosylcobalamin (3000 mcg). It contains methylcobalamin (3000 mcg). Vitamin B12 is water-soluble. This is why vitamin B12 supplements can exceed the reference intake by a large margin. This is considered safe. Research has not linked high vitamin B12 intake to harmful effects.

Quatrefolic® (5-MTHF) supports absorption

Quatrefolic® is also called a fourth-generation folate form. It has higher bioavailability than synthetic folic acid forms. We support stability by binding it to a glucosamine salt instead of a calcium salt. This calcium salt form is often linked to third-generation folate.

No extra nutrients needed for folate activity

Many standard folic acid forms must first convert into 5-MTHF before the body can use them. Quatrefolic® already contains the active form 5-MTHF. This means the body does not need extra support nutrients for conversion. Quatrefolic® is a leading folate form worldwide.

P-5-P (vitamin B6) supports vitamin B12 absorption

Vitamin B6 supports several important functions in the body. It supports red blood cell formation. It supports protein production. It supports cysteine formation. Pyridoxal-5-phosphate is the biologically active coenzyme form of vitamin B6. This form has higher bioavailability than pyridoxine. This form is also considered safer than pyridoxine. We use only P-5-P in our products.

Vitamin B6 supports red blood cell formation and protein production

Vitamin B6 supports the formation of red blood cells. It also supports natural energy in the body. It supports homocysteine metabolism. Homocysteine is an intermediate in the conversion of methionine into cysteine. Cysteine supports protein formation. It also supports glutathione production. Glutathione is a strong antioxidant. Quatrefolic® also supports this process.

Best absorbed forms

Methylcobalamin and adenosylcobalamin are well-absorbed forms of vitamin B12. They are biologically active forms. The body does not need to convert them in the stomach and intestines. Conversion steps can fail in some cases. Both methylcobalamin and adenosylcobalamin offer key biochemical benefits compared to inactive forms of vitamin B12. Cyanocobalamin is an example of an inactive synthetic form of vitamin B12. Manufacturers often use this form because it is stable and low-cost.
