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*

These are really good quality. The color is easy to see on the outdoor court, especially when the sun is bright. Definitely has good bounce to them.

Franklin X-40 vs. Dura Fast 40 (vs. Onix)
Size: 12 Pack, Color: Optic Yellow, Size: 12 Pack, Color: Optic Yellow
Review order: Review summary (quick read) Review update (4-13-2021) Full review (long read) Summary: This review might save you a lot of time researching balls, but here's the summary if you don't want to read the full review... For 4.0+ play consider the Dura Fast 40 when preparing for certain tournaments, but expect only about 2 games per ball, which is quite annoying in my opinion... for 95% of players, definitely go with the Franklin X-40 (except when preparing for a Dura only tournament of course). If you just want the ball to last and last year after year and don't care at all about egging or quality of play consider the much softer and much slower and much bouncier Onix ball. The Onix ball is so soft that I can't recommend it for typical play, but it is actually an excellent choice when introducing new players to the game and it is often the preferred ball in 65+ play if mobility becomes a common issue because extra bounce = extra time to get there, but in my area many older players seem to play the X-40 just fine. * * * * * * * * * * * * * * * * * * * * * * * * Update: 4-13-2021: Popularity: Almost everyone in my area is playing the Franklin X-40 in every park. I finally saw a Dura in play yesterday, but it's been a long time! Outdoor tournaments in my state are now about 60% X-40 and about 40% Dura (Washington), so even in tournament play the Dura seems to be going out pretty quick. Seasonal durability of X-40: for the first year I don't think my group cracked a single X-40 (despite having a faster paced game), but using that same batch of balls this Spring, they've all been dropping like flies so now my 1 year old batch of X-40's probably isn't much more durable than brand new Dura's (very annoying to deal with those cracks). I just bought new X-40's yesterday and I'll be discarding the few X-40's that are left from last year when the new stock arrives. It will be new X-40's for me once a year from now on assuming quality doesn't slide... fresh manufacturing is apparently very important, so hopefully Franklin will keep their runs moderate, and maybe that's what Dura did wrong.(?) * * * * * * * * * * * * * * * * * * * * * * * * Full review: This review will focus largely on the physical & quality comparisons between the Franklin Outdoor X-40 pickleball and the Dura Fast 40 pickleball, but I'll also give a summary of my impressions from the mouth of experts and supplement also by my own amateur impressions and measurements. Dura hole specs: 16 drilled holes @ 0.325" & 24 drilled holes @ .264" Franklin hole specs: 40 drilled holes @ 0.288" Both balls have 40 holes with an average hole size of 0.288", but the Dura ball has a far more randomized hole pattern. I personally didn't notice any difference in spin characteristics or any notable advantage to the randomized hole pattern of the Dura. Franklin weight: 26g Dura weight: 25g Both balls are rotationally molded in one continuous piece so the seam is just as strong as the rest of the ball on either ball... the appearance of a seam is on the outside of the ball only but the visual molding mark is not actually separated in any way in the middle of the ball and the inside of the ball will likewise appear 100% seamless on either ball, so no true seam exists (both balls are true "1-piece" balls). The Dura ball has much smoother molding marks w/ no plastic flashing like the Franklin... this is primarily cosmetic but quality in this regard definitely goes to the Dura. Subjective color preference: in the shade I think the Dura "Neon" color looks better (see pic), but in typical full sun the green tint looks dingy on the Dura ball in my opinion, and I feel the Franklin "Optic Yellow" is a crisper color that's probably a little more visible. These are the only 2 ball colors I have to compare. I would prefer more dye to be used for a green ball so it still looks green in full sun because in my experience with disc golf and ball golf neon green is the most visible color and neon pink is good too... with these 2 options I'd pick the yellow... the green tint on the Dura is so subtle in full sun it ends up looking more like a dingy yellow rather than a green. A more apples to apples comparison would be Dura's yellow option but I'm pretty confident Franklin would win that contest also based on the notably higher translucency in the plastic used by Dura. Color: Franklin wins. Franklin X-40 country of origin: China Dura Fast 40 country of origin: Vietnam - - EXPERT INSPIRED IMPRESSIONS - - From what I've gathered, expect much longer play per dollar out of the Franklin and expect very little life out of the Dura. Dura's are supposed to be a little harder/better/faster, but they often only last a few games based on everything I've read and heard. For older players consider the Onix over either of these balls... softer balls bounce higher and hit slower which allows more time to get to the ball for longer rallies... the Onix seems to be the favorite for play in older aged groups. Based on expert advise from the "pickleball kitchen" youtube channel... Best performance award (fastest, hardest): Dura Fast 40 Best Value (also w/ great performance): Franklin Outdoor X-40 - - - except high level players should opt for the Dura due to tournament requirements (note: this observation may be outdated... check tournaments in your state to verify what local tournaments are still using the Dura in your area and which tournaments have switched to the X-40) Longest lasting, but soft and bouncy: Onix Note: I have not seen a single outdoor tournament publish the Onix as their ball. My personal recommendation for most players based on a lot of reviews and some research and a close look would be to skip the Dura and go straight to the Franklin X-40 until you're playing tournaments... if/when you advance to the level of playing serious tournament play I don't think it would take long to transition muscle memory and power from the Franklin outdoor ball to the Dura ball and a lot of money and annoyance can be saved w/ the Franklin over the very brittle Dura... Franklin X-40 balls don't last very long either (according to some... possibly old stock), but compared to the Dura it's a notable improvement strongly worth considering even if you're a quality buff like myself. Manufacturing quality: Dura wins Material durability: Franklin easily wins and Onix lasts much longer still if you don't mind a notably slower game (more similar to indoor) and more egging. Quality of play: Mixed... many elite players prefer the extra speed of the Dura, but I prefer the consistency of virtually everyone using the same ball and even more notably, I'd rather sacrifice just a little speed to get the higher consistency / predictability / reliability of an uncracked ball and I find it distracting to look for cracks all the time. Value (w/o sacrificing much): Franklin Despite the long read, I'm hoping this helps the reader save some time in selecting a pickleball, especially for players new to the game.

Do not judge it by the color .. but by the quality of its build
Size: 12 Pack, Color: Ember
The most durable ball in South Texas heat. The bright color becomes matte after a few games, which I don’t mind. When I pull them out at local tournaments I get mixed reactions—to some not being yellow is like trying a new religion!. Most people do prefer the color that they’re used, I get that, but when I tell them it’s a fresh Franklin x40 most give em a go. Some even (sorry Trad pickleball gods) convert. When I see others bring their own I feel a level of affirmation on par with accidental cult leader getting their first members. So yeah, it’s a great performing ball in a color that pops, and a great value. I love this game

Better quality than the no-name brands
Size: 3 Pack, Color: Optic Yellow
I’ve played with quite a few different pickleballs over the past couple of years, including several cheaper “no-name” brands, and these Franklin X-40 balls consistently perform better for me. The biggest difference is durability. These seem to hold up much better to hard hits and regular outdoor play without cracking as quickly as many lower-cost balls I’ve tried. Even after multiple games, they maintain their shape and playability better than most bargain options. I also really like the bright optic yellow color. They’re easy to track during fast rallies and remain very visible in different lighting conditions, which makes a noticeable difference during competitive games. Performance-wise, they have a very consistent feel and bounce. There’s a reason these are used so widely in organized play and tournaments—they simply play reliably from game to game. While they may cost a little more than generic brands, I’ve actually found them to be a better value over time because they last longer and don’t need replacing nearly as often. Overall, these are my go-to outdoor pickleballs now. Durable, highly visible, and consistent on the court. Definitely worth it if you play regularly.

The Indispensable Standard for Outdoor Play
Size: 12 Pack, Color: Optic Yellow
As someone who genuinely lives on the pickleball court, having reliable equipment isn't a preference—it’s a necessity. The Franklin Sports X-40 Outdoor Pickleballs are the gold standard for a reason. From the moment you serve, the flight is true, offering predictable speed and a consistent, high-bounce off the court face, making every rally feel authentic and competitive. The 40 precision-drilled holes ensure that they cut through the wind effectively, minimizing drift on those breezy days that are inevitable in outdoor play. I’ve hit these with powerful serves and vicious third-shot drops, and they maintain their shape and integrity beautifully, far outlasting many other brands I’ve tried. However, let’s be honest about the one thing every dedicated player knows: you can never, ever have enough pickleballs. Even with the durability of the X-40, balls get lost in the bushes, occasionally crack under extreme force, or are simply needed for high-volume drilling. If you’re serious about the game, stocking up on these is essential—not just because they're great, but because having a full inventory is the only way to ensure the game never stops. If you’re looking for a ball that delivers official, tournament-level performance and holds up play after play, the X-40 is the one to get.
