My go-to in the evenings, or about an hour after my last session of the day. There’s no better recovery than sleep, so anything that helps promote it is hugely beneficial to performance.”

Jan Frodeno, 3 x Ironman World Champion

"Sleep has always been one of the most important aspects of recovery to me. However, it can be tough to always get a good nights sleep, especially now that I have two kids!

When I took PILLAR, I literally saw through my sleep data, that my quality of sleep improved!"

Ben Kanute, Olympic Triathlete

“I wasn’t a big supplement user previously, but with PILLAR, I now understand the value high quality micronutrition has on recovery and performance. I’ve never slept better.”

Brett Robinson, Olympic Marathoner

"To be honest I was never a big believer in supplements but when I heard how PILLAR's Triple Magnesium would improve sleep I gave it a try and my sleep data doesn’t lie. As sleep is my number one priority in terms of recovery this is a game changer in my opinion."

Freddie Funk, 6 x Ironman 70.3 Champion

“My deep sleep improves by 9% when I have more magnesium according to my WHOOP data. It is more clear on the nights when I forget to take my magnesium. It's now a non-negotiable for me before bed nightly.”

Ellie Salthouse, Ironman 70.3 Champion

"Triple Magnesium is now a nightly ritual before bed. My sleep performance results have been remarkable. Importantly for me as a tested athlete knowing PILLAR runs a highly rigorous product testing policy."

Magnus Ditlev, Professional Triathlete

“I’ve finally had a consistent week recording sleep and loading up on magnesium right before bed and the improvement throughout the week is very clear. More relaxed, less stress and better recovered."

Steve McKenna, IRONMAN Australia Champion

"As an athlete, I’ve tried many recovery tools but sleep has always been my number 1. I always thought I had decent sleep but Pillar Triple Magnesium has really transformed it for the better, allowing me to get the most out of my sleep so that I can get the most out of my day."

Grace Thek, Professional Triathlete

"Triple Magnesium (I prefer the tablets) is my choice in the evenings. I take 2 tablets just before I go to bed. Sleep is a non-negotiable factor for my recovery."

Gwen Jorgensen, Olympic Gold Medallist Triathlete

Frequently Asked Questions

Why is PILLAR magnesium different?

Most athletes have supplemented with ‘Magnesium’ at some point in time - often trying to support sleep, muscle recovery or to fix cramping issues - yet almost all have failed to find any noticeable benefit and thus stopped. The problem is these athletes are using products not designed for them. Pharmaceutical companies have always focused on mass sedentary populations, thus the ‘forms’ of magnesium and the potency within the formulations are not solving the need states of endurance athletes. PILLAR’s Triple Magnesium range was purposefully curated to support sleep and muscle recovery for endurance athletes. Using leading sports science research, a selection of the most bioavailable forms of magnesium were formulated at appropriately high potency. While the pharmaceutical industry focuses on a sedentary demographic, PILLAR unapologetically supports performance outcomes.

Do endurance athletes require more magnesium?

Athletes require more. Full stop. Just like macronutrients; protein, carbohydrates, and fats, are required at greater levels for athletes. This same exists for micronutrients. Magnesium is depleted through sweat, urination, and lipolysis; all incurred at greater levels when undertaking endurance exercise. Therefore, those participating in endurance sports need to be aware that they deplete magnesium at far greater rates than sedentary people

How does magnesium aid sleep?

Magnesium is the vital micronutrient to support sleep as it is a cofactor in the hormone synthesis of serotonin which the brain transforms into melatonin.

What is magnesium bisglycinate?

Magnesium Bisglycinate is the combination of Magnesium bound to the amino acid, Glycine. Glycine works synergistically alongside many neurotransmitters – like GABA –to promote sleep and speed up the recovery process. It is well-tolerated and well-absorbed, unlike other forms of Magnesium (such as the cheaper, more commonly found Magnesium Oxide). For this reason, it is also far less likely to cause laxative effects or gastrointestinal stress.

When is the best time to take magnesium for performance outcomes?

The inclusion of magnesium Bisglycinate in TRIPLE MAGNESIUM, in addition to the other highly bioavailable forms, means this product supports the nervous system and helps with sleep, muscle relaxation, and overall recovery. This makes it best suited to take in the evening, about an hour or so before bed for most people.

Takes good, but...

Magnesium citrate is a laxative. Literally, it is a saline laxative. So even though this supplement tastes OK, the benefits are largely from the magnesium glycinate. And if you're having some stomach troubles after taking this, well... it's because you took a laxative. Didn't realize this until my doctor told me.

Need to SHAKE

I am happy that there is a magnesium product that is NSF certified. I found that magnesium really helps with my sleeping and recovery. This product is an every night sort of deal. You just HAVE to shake it if you want it to taste good- if you just stir it is quite lumpy. Maybe one of those hand frothers would work better! Taste is pretty artificial- seems like thats all you can get on the market these days though! Pineapple one is better than the berry in my opinion!

Excellent product

Have found this to be an excellent product. Taken 1 hour before I go to sleep I have found my deep sleep and recovery is consistently higher (tracked through) whoop.
Will definitely continue using this as my nightly routine

Triple Magnesium Powder

Wow. After taking one jar of Triple Magnesium over the last month or so I am feeling great. Much less joint and muscle discomfort even after training for a half marathon and completing the event over the weekend. I am almost 74 years old so excited to have found something that appears to help so many ch with aches and pains

jarrod montgomery
