Our Mission

The singular mission of MAGNAK is to help athletes achieve their best. Most athletes are limited physically and fail to push their limits due to physical barriers such as muscle cramps, and the aches and soreness that follow afterwards. We believe that through our unique and scientifically proven formulation that replaces the "missing" mineral magnesium, we can help athletes reach their goals and hit more PRs!

Developed by an award-winning physician and a world-famous endurance athlete, MAGNAK is the perfect electrolyte formula to ward off muscle cramps.

A world-famous endurance athlete, James Lawrence achieved the impossible in 2015 when he complete 50 full-distance triathlons consecutively in 50 days, across all 50 states [50-50-50].

The birth of MAGNAK

In the spring of 2017, our Founder, Dr. Kharait, was hiking Clouds Rest, one of the highest peaks in the Yosemite Valley. At the Summit, it hit him- a muscle cramp. It was so bad that he was almost carried down for an hour before recovering. This was despite being well hydrated throughout the course. And he decided to build a better formulation- something that truly prevents cramps during endurance feats and helps muscles perform better—day after day. And the idea of MAGNAK was conceived!

How MAGNAK is different

Most sports drinks and electrolyte mixes follow the old adage of "some sugar and some salt in water". Others use caffeine in their drinks despite the fact that caffeine is a diuretic (it dehydrates you!). Some "sprinkle" other electrolytes without a detailed understanding of "why?".

We go into the depth of the science - because our goal is not to make just another formula, but the best one. We started our formulation by identifying the electrolytes that are needed and eliminating what we did not need. We then proceeded with an understanding of their absorption, their (volume of) distribution within the body, their loss in sweat and then tested them out on the most extreme endurance athlete, James Lawrence. If it works for him, it will work for you!


Questions? We'll try answering what we can in the FAQs below. Otherwise, feel free to contact us!

What is Magnesium?Up

Magnesium is an electrolyte or an ion that plays a critical role in many cellular processes. Particularly, magnesium is required to make energy, as ATP that is utilized by our cells. Loss of magnesium, as happens with exercise and other conditions can lead to significantly sore muscles and a fatigued body.

Why is the formula called MAGNAK?Up

Because it contains 3 important electrolytes that are lost in sweat with heavy exercise: Magnesium (Mg), sodium (Na) and potassium (K).

Why is MAGNAK Speed Sauce unique?Up

Currently, there are very few sports drinks that are rich in magnesium. MAGNAK is rich in electrolytes, low in sugar and calories, has natural flavors and no preservatives, harmful additives or sweeteners. The optimized ratios and proportions of electrolytes in the formula help prevent muscle cramps and soreness. All of these make it unique.

What can an athlete feel after drinking MAGNAK Speed Sauce?Up

Athletes can expect to feel better hydrated and energized (with natural electrolytes as opposed to having a caffeine “rush” which often leads to a later “crash”). Magnesium in our formula, relieves muscle cramps in people especially with its nutritional deficiency.

Why do athletes NOT have bloating with MAGNAK Speed Sauce?Up

Speed Sauce is easier to absorb from the gut due to its low osmolarity (or loosely termed as “thickness”); the low sugar content drives the intake of other electrolytes rapidly within the blood stream preventing the solution from sitting in the gut for too long. Hence, athletes do not have bubble gut with Speed Sauce.

What about water for hydration? Isn’t water the best?Up

Nothing replaces water for hydration. However, athletes engaged in regular heavy workouts lose salt in the sweat and utilize other electrolytes (sodium, magnesium, etc.) and can eventually have sub-clinical deficiency. This impairs their performance. Hence, for those with endurance feats and marathon runs, water is not enough for hydration especially if they need to perform better, every day.

What is hyponatremia and how does this happen in endurance athletes?Up

Hyponatremia is LOW SODIUM. Almost 20% of endurance athletes or marathoners develop this condition, largely due to a habit of drinking too much water (or hypotonic drinks) prior to starting the run. As the race progresses, body releases vasopressin or anti-diuretic hormone from the brain that helps conserve water from being excreted in the urine. This along with salt wasting in the sweat leads to a dilution of sodium in the blood and can lead to a dangerous condition. Hence, having some sodium (salt) in the mix is very critical.

Why is MAGNAK Speed Sauce NOT sugar-free?Up

We know for a long time now, that sodium is absorbed from the gut using ion transport with amino acids and sugar. In other words, the presence of small amount of sugar facilitates absorption of sodium via sodium-dependent glucose co-transporter (which are specialized channels in the intestine). In sugar-free drinks, this additive benefit on sodium absorption is lost. Small amount of sugar also serves as an immediate source of energy during those long runs.

How does magnesium deficiency manifest?Up

Magnesium deficiency is surprisingly common, possibly due to processing of food. Magnesium is not that easy to find in dietary sources (unlike sodium). Long term deficiency can manifest as muscle cramps, soreness, fatigue, insomnia (lack of sleep) and restless legs.

What is the relationship between potassium and magnesium?Up

Magnesium is very important in keeping the potassium from leaking out of the body. In magnesium deficiency, potassium levels usually run low but replacing potassium alone cannot work because lack of magnesium leads to a loss of potassium in the urine.
