Advanced B-Vitamin Technology for Peak Performance

Longevity B-Complex delivers what your aging body actually needs—not just what’s trending. This doctor-developed formula provides a full-spectrum of essential B vitamins, delivered in a base of Himalayan shilajit for enhanced nutrient transport. Designed for morning use to help you feel sharper, more energized, and more resilient—everyday, at every stage of life.* 1,2,4,5

Pioneering Longevity Since 1988

For over 36 years, ProHealth has been dedicated to crafting the world’s highest-quality supplements—rooted in innovation, integrity, and a passion for healthy aging. With a long-standing A+ rating from the Better Business Bureau, our reputation for purity and potency has made us one of the most trusted names in the industry. Our commitment to scientific rigor, premium sourcing, and results you can feel continues to drive everything we do.

Why Most B-Complex Supplements Fall Short

The average B-complex is built for the masses, not for those optimizing longevity, performance, and cellular health. Most formulas still rely on outdated forms like folic acid and cyanocobalamin, paired with dosages that miss the mark—either too low to be effective or too high to be well-tolerated.

This becomes especially problematic after age 50, when nutrient absorption declines, methylation slows, and your body’s demand for B vitamins increases. If your current supplement isn’t activated, methylated, or food-based, it’s likely falling short.1,6

A truly effective B-complex should work with your biology—not against it—and deliver results you can actually feel.*

The Science of Better B-Vitamins

B vitamins are critical coenzymes for virtually every major system in your body: from energy production and detoxification to neurotransmitter synthesis and DNA methylation.*1,2,7

But as you age, several challenges emerge. B vitamins are water-soluble and quickly excreted in urine, making it difficult to maintain adequate levels. Absorption also declines naturally with age, and more than 30% of adults over 60 are estimated to have suboptimal levels of vitamin B12. Up to 18% may also be low in thiamine—two of the most critical B vitamins for neurological and metabolic health.*1,6

This creates the perfect storm: your need for B vitamins increases, but your body’s ability to absorb and utilize them declines. Factors like reduced stomach acid, enzyme inefficiency, common medications, and slower methylation all contribute to this gap.*1,6

Longevity B-Complex is designed to fill that gap—supporting foundational biological processes that tend to slow in your 50s and 60s, and delivering the preferred forms your body can recognize, absorb, and use right away.*1,4,6

What Makes Longevity B-Complex Ideal for Aging Adults

At ProHealth, we begin with 100% of the Daily Value of all essential B vitamins, sourced from fermented, food-based nutrients for enhanced absorption and digestive comfort. Then we go further—adding activated and methylated forms for therapeutic potency and optimal bioavailability.*4,8

  • Methyl B12 (methylcobalamin) and methyl folate (5-MTHF) bypass common MTHFR gene variants that affect up to 40% of adults, ensuring immediate support for neurotransmitter synthesis, red blood cell formation, and homocysteine metabolism—without burdening the body’s detox pathways.*1,2,9
  • Active B6 (P5P, pyridoxal-5'-phosphate) combined with active B2 (R5P, riboflavin-5’-phosphate) provides direct support for the production of serotonin, dopamine, and GABA—critical for mood, stress resilience, and cognitive clarity as we age.*2,9
  • Benfotiamine, a fat-soluble form of B1, is included for its superior tissue uptake and potential benefits for nerve health and glucose metabolism—especially relevant in aging populations.*1,9,10
  • Fermented forms of all B vitamins help drive the Krebs cycle and mitochondrial ATP production, the core energy-generating process that powers every cell in your body.*1,11,12
  • Shilajit (standardized for fulvic acid, source of trace minerals) acts as a powerful nutrient driver, helping transport B vitamins into the mitochondria where they’re converted into usable energy. This is especially important in older adults, where nutrient transport and mitochondrial efficiency naturally decline.*5,13

A Word from our Chief Science Officer

“B vitamins are often overlooked—but they’re some of the most powerful molecules for longevity. In their activated, methylated, and fermented forms, they don’t just support energy—they unlock it at the cellular level, fueling mitochondria, optimizing methylation, and driving detox pathways. I designed our Longevity B-Complex to go beyond standard B formulas, combining next-generation forms with shilajit and benfotiamine to help nourish the body’s core energy systems and spark vitality from within.”

Quick and Fantastic Service!
I include the additional protection for all of my high dollar purchases. This was the first time I have ever had to use it. I had an extension to provide additional screens to my laptop. Unfortunately, it developed an issue. Submitting a claim was easy and straightforward. UPS came the next day to pick it up and I was notified in just a couple of days that it was received. Only a couple of days after that, I received an email stating that my laptop screens were not repairable and I was given an Amazon card for the entire purchase price. I could not have been more pleased, as the purchase price was $599 and was a huge splurge for me in the first place. I was able to quickly replace the screens and back in business in no time. I would recommend this protection plan for any high dollar purchase.

They paid on the policy
I bought a four year replacement policy on my modem and two years into its lifespan it stopped working. I trouble shot with the company but we eventually determined it was dead. I contacted Asurion, they sent me a pre-paid address label, I mailed the defective modem, they found that it was dead and deposited a credit in the amount of the original purchase in my Amazon account, all within a few days. I am quite happy with the service. Just so you know, the reimbursement is through a gift card at Amazon which you can draw down against your purchases; it is not CASH.

Nearly 3 years later, Asurion had my back :)
In Nov of 2017 I bought a $900 35" Ultra wide PC monitor for Gaming and Work. It was made by a company called AOC/Envision and I bought it through amazon. The monitor had a 3 year warranty that I was still within but they said no to a defect that they said was only covered for 1 year, even though it wasn't the type of defect that was only covered for 1 year. LUCKILY, back in 2017 I had purchased an Asurion insurance policy with this monitor. I told an Asurion agent in a instant messaging chat window on the Asurion website my problem and she sent me postage in an email. I shipped my product and in 5 days from shipping it I received a text telling me that it was beyond repair and I would be getting a FULL REFUND! Not 2hr later, in an email, there it was, an amazon gift card code for $900 I will not be making any big purchases without an Asurion plan going forward. Happy customer Don't buy anything AOC

Received a refund
I purchased the 4-year protection plan offered at the time I purchased a refurbished printer. Seven months later the printer failed, so I went searching through my Amazon orders for my protection plan and located it. Once I created an account on Asurion's website it showed the the plan but it was not attached to a specific purchase, so I had to locate and upload the invoice for my printer. Once that was done, the policy still wasn't linked for some unknown reason. I proceeded to start the claim anyway stating that my printer had failed and I received an immediate reply stating that a box would be shipped to me for me to return the printer for inspection/repair. After a week I hadn't seen any additional info so I called their support phone #. The service was very good and they had to create a new case to replace the one I started online, and they assured me that a shipping box would be sent. About a week later I did receive the box with a prepaid shipping label to return the item by UPS. I packaged the printer up and sent it off. I received updates stating that they received it, were looking at it and attempting repairs. Everything appeared to be going along well, then out of the blue they sent me a notification of a full refund in the form of an Amazon gift card. Overall I'm satisfied and I'm glad I purchased the coverage.
