HAK Nutrition Post HAK: An Evidence-Based Review

Post HAK is a post-workout  recovery supplement by HAK Nutrition, the brand behind our Top Rated Pre-Workout, Pre HAK.  Based on the Pre HAK formula, HAK Nutrition appears to be a brand that places an emphasis on highly effective, clinically dosed formulas, as opposed to the usual under-dosed garbage that tends to fill the shelves…

So let’s take a look at the Post HAK formula and see if it falls into that same category of top notch, scientifically sound supplements…

Post HAK Claims

When it comes to evaluting supplements, it’s all about analyzing the ingredients and determining if the claims made by the makers of the product (in this case HAK Nutrition) can realistically be acheived.

At SuppWithThat.com we just follow the science to determine this.  That’s all…

Post HAK is a post-workout recovery supplement, meaning it’s meant to be taken just after working out.  It contains a wide array of ingredients, each with a specific function that contributes to the efficacy, but as a whole, Post HAK:

  • Increase  Strength/Endurance
  • Enhance Recovery From Exercise
  • Promote Muscle Growth
  • Reduce Soreness
  • Reduce Fatigue

Sure, those are some pretty strong claims, but then again…Post HAK is a strong formula.  Let’s take a look at each ingredient to gain a better understanding of why Post HAK is truly one of the best Post-Workout Recovery Supplements seen so far…

Post HAK Ingredients

Post HAK contains 10 active ingredients if you consider BCAAs (Leucine, Isoleucine, and Valine) as three separate ingredients, that is.  Lucky for us, every ingredient present in Post HAK has tons of research behind it, making it easy to determine not only if the ingredient works but also at what dose.

Let’s dive on in…

L-Citrullie DL-Malate (2:1)

Ciutrlline is an amino acid, naturally present in Watermelon, which fulfills a variety of functions in the human body.  The notable of which are:

  1. It’s involvement in the Urea cycle
  2. It’s ability to increase Nitric Oxide levels

At doses ranging from 6-9g, Citrulline (usually as Citrulline Malate) has been shown to enhance muscular endurance, allowing athletes to complete more reps when muscular fatigue would normally set in.  This is due to Citrulline’s ability to reduce Ammonia build-up in working muscle tissue.

As previously alluded to, Citrulline has also been shown to increase Nitric Oxide levels via it’s ability to convert into Arginine which in turn converts into Nitric Oxide, while avoiding the Arginase enzyme that stops supplemental Arginine itself from being effective in this regard.

As it pertains to recovery:

Citrulline Malate has actually been shown to reduce muscle soreness.  Eiether of the above mechanisms could be responsible for that, since both Ammonia reduction and enhanced oxygenation (via increased Nitric Oxide) could potentially yield this benefit.

So, there’s really no doubt about it.  When you take a look at the research behind Citrulline, it’s easy to see that it’s a worthwhile ingredient in any pre or post workout supplement.

Post HAK contains 3g of L-Citrulline DL-Malate in a 2:1 ratio.

Betaine Anhydrous

Betaine is unique in that it has been the subject of several studies, specifically in the area of performance enhancement, and although it has been shown to:

It’s precise mechanism (or mechanisms) remains unclear.  The prevailing theory is that, because Betaine functions as an Osmolyte, supplementation results in a phenomenon known as “cellular swelling”.  This is simply when excess water is drawn into (muscle) cells and would explain the main benefits associated with Betaine.

If you’re interested in learning more about Betaine, check out this article.  Otherwise, read on…

Post HAK contains a true clinical (2500mg) dose of Betaine.

L-Carnitine L-Tartrate

When it comes to promoting favorable recovery from exercise, it doesn’t get much better than L-Carnitine L-Tartrate.

This unique, quickly absorbed form of Carnitine has been promoted for a variety of benefits, including fat-loss, but research in the area of exercise recovery has been particularly promising.

At doses of 1-2g/day, L-Carnitine L-Tartrate has beens shown to reduce bio-markers (biological inidcations) of muscle damage.  Similar results have been obtained in further studies and one study noted that the results may be attributed to an increase in muscle oxygenation.

More oxygen in muscle tissue would explain some of the studies involving Carintine, in various forms, improving physical performance.

Post HAK contains a solid clinical (2000mg) dose of L-Carnitine L-Tartrate, guaranteed to reduce recovery time, soreness, and possibly even enhance your performance in the gym.

Creatine HCL

Creatine HCL is an alternative form of Creatine which is generally promoted as more bioavailable than Creatine Monohydrate.

While this notion remains unsupported by science (in fact, logic suggests that Creatine HCL freely dissociates once inside the stomach due to an abundance of HCL, and is reduces to the basic Creatine molecule), it is true that Creatine HCL is more water soluble.

This doesn’t mean it’s better, or you can take less than if you used Monohydrate (you still need 3-5g/day to gain musclit e and strength over time), but it’s easier on the stomach for sure.

Post HAK contains 2g of Creatine HCL.

BCAAs (3:1:1)

BCAAs are one of the most popualar types of supplements when it comes to bodybuilding, though the efficact of such supplements as they pertain to muscle growth and performace enahcement have been called into question by some.

While it is true that Leucine, the “master” amino acid of activating muscle protein synthesis, is the most important of the three and the other two (Isoleucine and Valine) probably don’t help much in the way of muscle growth, there’s plenty of scientific evidence to support certain uses of BCAAs, especially when it comes to exercise recovery.

BCAAs have been shown to reduce indications of muscle damage, thereby enhancing exercise recovery and Leucine alone has been shown to put a stop to muscle breakdown in instaces of low protein intake.

So, while skeptics of BCAAs are right to say the benefits of BCAAs have been exaggerated, they do have legimiate functions that make them worth incroporating in any post-workout recovery supplement/stack, especially Leucine.

You can read all you want about BCAAs, the contraversy behind them, and the science which supports their use for certain things (namely exercise recovery) in this article.

Post HAK contains a solid 6g of BCAAs in an odd 3:1:1 ratio.  While the ratio doesn’t really matter, what does matter is the Leucine content and, given a 3:1;1 ratio of Leuciene to Isoleucine to Valine, Post HAK contains around 3.5g of Leucine per serving, a clinically effective dose capable of promoting optimal muscle growth.

Leucine is especially useful for Fasted Trainining, to negate the negatives while preserving the positives.

L-Glutamine

L-Glutamine rose to extreme popularity in the early days of Bodybuilding, but has since been scrutinized in the form of research papers which clearly prove that the benefits have been exaggerated by the mainstream supplement industry.

There is no solid evidence to suggest that Glutamine can:

  • Increase Muscle Growth
  • Speed Up Recovery
  • Improve Performance

What does exist, however, is preliminary research indicating a strong correlation between exercise-induced immunie suppression and plasma Glutamine levels.

In other words, when you exercise for long periods of time, your Glutamine levels may drop and since Glutamine itself plays a vital role in general immune function, supplementation may help to protect against exercise-induced immmune suppression.

Based on the research, this appears to be mostly relevant to endurance athletes or people who run marathons.  Basically, exercise that exceeds two hours of non-stop activity.  Short duration exercise does not deplete Glutamine levels enough to meaninfully impact immune function, for the most part.

Post HAK contains 3g of Glutamine, higher than you’ll usually find in Post Workout Supplements and ultimately capable of doing some good (if you need it).

Tart Cherry Extract

Tart Cherry Extract possesses anti-oxidant properties which have made it quite popular as a post-workout supplement in recent years.

Reserach indicates it may mitigate some of the oxidative stress associated with exercise and is therefore an effective recovery supplement, worth considering by anyone who wants to recovery faster and get back in the gym feeling good.

More studies are needed before we can establish a real “clinical range”, and some of the studies have used Tart Cherry Juice as opposed to an extract of some kind (further complicating the whole clinical dosing matter) but Post HAK contains 400mg per serving.  That’s more than you’ll find in most competing products.

Magnesium glycinate glutamine chelate

Magnesium Glycinate Glutamine Chelate is a novel form of Glutamine which serves as both a source of Magnesium and Glutamine.  Glutamine, which we discussed above, may play a role in reducing exercise-induced immune suppression, but Magnesium has a TON of benefits…

And guess what?

Many people are Magnesium deficient and don’t even know it.  Extreme deficiency can result in:

  • Impaired Cognitive Function
  • Muscle Weakness
  • Impaired Coordination
  • Muscle Cramps

And the list goes on…

We just picked the most relevant to exericise, but trust us, you DON’T want to be deficient in Magnesium and unless you regularly eat foods like:

  • Nuts (Various Kinds)
  • Leafy Greens (Spinach, Kale, etc.)
  • Fish (Various Kinds)
  • Beans (And Other Lentils)
  • Whole Grains

You’re probably not getting enough Magnesium.  It’s also worth mentioning that exercise may significantly increase your daily Magnesium requirements.

Post HAK contains 400mg of Magnesium Glycinate Glutamine Chelate, yielding 10mg of Magnesium.

Post HAK Ingredient Takeaway

Post HAK contains several scientifically proven ingredients at clinically effective doses, so is actually one of the few post-workout recovery supplements that actually lives up the claims.

Given the ingreidet profile, and clinically effective doses of those ingredients, you can expect Post HAK to:

  • Optimize Recovery (Reduces Soreness, Faster Repair, etc.)
  • Promote Muscle Growth
  • Enhance Strength/Stamina/Endurance
  • Reduce Fatigue (Both Physical And Mental)

This makes it one of the few post-workout recovery supplements we’d actually recommed, but if you really want ot maximize your results, you should consider stacking Post HAK with Pre HAK…

Stacking Pre HAK And Post HAK

You don’t have to scrutinize the Supplement Facts panels for Pre HAK and Post HAK to realize they stack very well together.

Although each of them contains some of the same ingredients, suchas Citrulline Malate and Betaine, there are several synergistic possibilities when using both Pre and Post HAK.

This makes stackin them a good option for anyone who wants to truly maximize each and every training session.

Post HAK Supplement Facts

Ultimately, although there is some overlap in terms of ingredients, Pre and Post HAK are worth stacking by anyone who can afford it.

Is Post HAK Safe?

Absolutely.  Not only has every ingreident in Post HAK been studied extensively and used by millions of people without adverse effects, but it’s completely non-stimulant, so even those who are sensitive to stimulants need not worry.
