Active B12 5000 by Seeking Health provides two active “coenzyme” forms of vitamin B12, methylcobalamin and adenosylcobalamin, in a high-potency, easy-to-take lozenge form. As “coenzyme” forms, methylcobalamin and adenosylcobalamin are the forms required by certain B12-dependent enzymes and reactions within the body. Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis. Vitamin B12 functions as a cofactor for methionine synthase and L-methylmalonyl-CoA mutase. Methionine synthase catalyzes the conversion of homocysteine to methionine. Methionine is required for the formation of SAMe (S-adenosylmethionine), an important methyl donor.*

Vitamin B12 is naturally present in seafood, shellfish, liver, eggs and dairy products. It may be harder for vegetarians and vegans to meet their daily needs for vitamin B12 from food sources without relying on supplements or fortified foods.*

Typical absorption of vitamin B12 is facilitated by intrinsic factor (IF), a natural protein produced by the parietal cells of the stomach lining. Higher doses of vitamin B12 may be supportive for individuals with lower IF levels, as large doses of B12 may be able to use absorption mechanisms that do not rely on intrinsic factor.*

As each individual may have different needs for vitamin B12, the potent dose of this vitamin contained in Active B12 5000 may not be ideal for everyone. Working with a qualified healthcare professional is the best way determine the appropriate dose for your individual needs. The lozenges can be broken down into halves or quarters if a lower dose is desired.

If you are looking for a similar product with methylfolate, consider our Active B12 with L-5-MTHF. For a similar product without the methylcobalamin, consider our Adeno B12. For vitamin B12 in the form of hydroxocobalamin, consider our Hydroxo B12.

Suggested Use

Take 1 lozenge daily or as directed by your healthcare professional. Lozenge may be broken into smaller pieces if lower dosage is desired.

Warnings

Children and pregnant or lactating women should consult their healthcare practitioner prior to use. Do not use if tamper seal is damaged. When taking high levels of B12, use under the care of a qualified physician and track blood levels. Consult with a healthcare professional before use if you are using antibiotics or other medications.

B12 Increase / Honocysteine Decrease
Effectiveness

Using a combination of Active B12 and Multivitaims, in the past 12-14 months I increased my B12 from 467 to 861. My MMA (Methylmalonic Acid) came out at 93 versus range of 87 to 318. And I dropped my Homocysteine from 15.5 (which my MD said nothing about) to 6.9. All by studying Dr. Lynch’s work, using Strategene, including the Facebook group, and investigating various other sources the these led me to. Had no medical support other than giving me blood work orders that I had to pry out of their hands. Review by Dennis (Posted on 3/5/2019)

Never been so blessed by a B12 supplement and extensive health challenges have heretofore necessitated my experience with myriad others, all sub par compared to this GEM of a product by Seeking Health. Hits the mark (and then some!) for delivering SYSTEMIC benefits from the get-go. Truly, formula and Company itself of worth greater than gold! Review by Beth (Posted on 12/24/2018)

I believe in the quality and effectiveness of Dr. Lynch's products. Will never buy B vitamins anywhere else. This has helped to bring down my homocysteine levels faster than health food store vitamins. Showed the bottles to my endocrinologist, and she was familiar with Dr. Lynch and had been following his research. Review by cm (Posted on 12/16/2018)
