Introducing ProHealth Calcium AKG Longevity, a revolutionary supplement that targets multiple pathways of aging. Alpha-ketoglutarate (AKG) is an essential molecule naturally produced by the body that plays a central role in energy metabolism and cellular repair. However, AKG levels decline sharply with age—dropping up to 10-fold between the ages of 40 and 80. Supplementation is necessary to maintain optimal levels as the compound is not found in food.1*

Supplementing with Calcium AKG Longevity addresses this deficiency by supplying you with a bioavailable form of AKG, designed to cross the cell membrane and fuel critical metabolic processes. It supports ATP Production, helping to enhance mitochondrial function and promote efficient energy production through the Krebs cycle. It also helps maintain DNA integrity and regulate gene expression and DNA methylation, which are key factors involved in healthy aging.*

Additionally, AKG acts as a precursor to the compound glutathione, which has antioxidant effects and helps neutralize ammonia in the body, supporting a healthy detoxification process.*

In animal studies, AKG has been shown to help extend lifespan by 10% in mice, 23% in flies, and 50% in worms.1 In human studies, AKG supplementation shows promising results for reducing biological age markers and improving overall vitality. This may be due to its effects on key pathways associated with aging, including rapamycin (mTOR) and AMP-activated protein kinase (AMPK).3*

Extend a Healthy Lifespan with Calcium AKG Longevity*

Boosts Cellular Energy Production*
Calcium AKG supports cellular energy by fueling the Krebs cycle, which enhances ATP production and ensures that your cells have the energy needed for optimal function. Additionally, it plays a critical role in maintaining mitochondrial efficiency, helping to combat the natural decline in energy associated with aging.2, 4*

Supports Longevity Pathways*
Calcium AKG regulates key longevity pathways, including mTOR and AMPK, to promote a healthy balance between cellular growth and repair. This regulation is essential for supporting the body’s natural processes that maintain cellular health over time. Calcium AKG also plays a role in DNA methylation, which helps regulate gene expression and supports healthy aging at the molecular level.2, 3, 1*

Helps Maintain Bone Density*
As a valuable source of calcium, Calcium AKG provides 15% of the daily recommended value, supporting bone strength and density. This benefit is particularly important for aging individuals, as maintaining adequate calcium levels can help reduce the risk of age-related frailty and promote long-term physical resilience and strength.6*

Supports Healthy Neurotransmitters*
Calcium AKG contributes to mental clarity and calm by supporting neurotransmitter balance. Specifically, it converts into glutamate, which is a key precursor for GABA, the brain’s calming neurotransmitter. By enhancing GABA production, Calcium AKG helps regulate the brain’s response to stress and supports a balanced mood and restful sleep.2,3,5*

Encourages Detoxification and Antioxidant Production*
Calcium AKG aids the body’s natural detoxification processes by serving as a precursor to glutathione, the body’s master antioxidant. Glutathione plays a crucial role in combating oxidative stress and supporting overall cellular health.* Additionally, Calcium AKG helps neutralize excess ammonia in the body, which can support both brain and muscle function, promoting optimal performance and resilience.3, 5*

Helps Maintain Strength*
Much of AKG is metabolized into glutamine and other essential amino acids that can aid in the maintenance of lean muscle mass. By potentially supporting bone health, muscle function, and cellular energy production, Ca-AKG may help maintain physical strength and vitality as you age, enabling you to stay active and engaged in life's adventures.3,8*

For athletes, studies indicate that daily doses of 3 to 4 grams of AKG, administered 1–2 times per day, may improve endurance and anaerobic capacity. Supplementation for a period of 4 to 8 weeks appears to be effective, with administration typically in powder or capsule form. For immediate performance benefits, taking AKG before exercise is commonly recommended.7*

Aids in Immune Function*
Glutamine also functions as fuel for gastrointestinal and immune cells, contributing to a healthy gastrointestinal lining and immune system. Supplementation may aid in overall immune defenses, as glutamine is an important fuel for lymphocytes and macrophages, types of white blood cells that can help fight against pathogens.5,8*

#1 Tire Repair
Size: 16 oz
This stuff is Fantastic. I have a riding lawn mower and one of the front tires, which is small, had been running low for a couple of years, we took it off. to fill it with the liquiTube and you could see cracks all around the outside of the tire. The liquid tube oozed out of one of the cracks and sealed , immediately. My brother rolled the tire around real good before we put it back on the track lawn mower. It has been 3 days now and today I mowed for 1 1/2 hrs and the tire as full as it was the day we put in the LiquiTube. This stuff is fantastic, it really, really works!

Hard to install as instructed.
Size: 32 oz
Nearly impossible to get it in the tire through the valve. Yes I removed the valve core. Broke the bead on the tire and dumped it in. That worked great! So far no leaks. They should definitely redesign the installation method.

Been using it for 15 years! Not sure where the Neg reviews come from?
Size: 16 oz
I've been using Liquitube since around 2010. I use it religiously in my ATVs and lawn tractor tires. Since I've been using this stuff, I've never had a flat before. I've pulled out nails and slivers of steel out of my ATV tires but yet none of them lose air or go flat. I think some of the negative reviews come from improper use of the product or not enough of the product is being used in the tires. I think this come from variance in formula charts that Liquitube has had in the past on their bottles and on their website. The chart on their website wouldn't match the formula that was provided on the bottle. So I think alot of people get mixed up and not knowing the correct amount to add to each tire. Now Liquitube just puts pictures on the side of the bottle with an ounce measurement below each picture to tell people how to use it. But even that can be confusing. For instance, take the picture of the ATV that they show. Below the ATV it says 32oz. Now some people probably think the 32oz is for the entire ATV. Well that isn't the case. They want you to use 32oz Per Tire! Years ago Liquitube even used to say on the bottle to use 32oz per tire on an ATV. Now they just show a picture with an amount below it. Now you'll come to find out that the 32oz they recommend doesn't match up to the formula they tell you to use to calculate how much each tire is supposed to get. So if you use the formula provided, you come to find that it calculates out to use less product per tire than what the bottle tells you to use. So that's very confusing as well. So if you use it long enough, you'll be able to know how much each tire will need from experience. Just make sure there's enough on the inside of the tire to coat the entire inside as well as leaving a bit left over to circulate in the tire so it can be ready for a large puncture if that ever happens. All in all, it's a good product that does what it claims. It lasts for as long as the tire does and it doesn't freeze up in the cold either! 5 stars!
