Magnesium is a mineral that is a key part of protein synthesis and energy metabolism. We need magnesium to help with muscle building and the breakdown of carbohydrates into glucose for energy. Adequate intake of magnesium in athletes has been shown to:

·      Help regulate glucose distribution to both working muscles and the brain in athletes, which can help increase time to fatigue during intense exercise

·      Improve bone health

·      Increase the strength of muscle contractions

·      Improve sleep quality 

We feel like the real question is, what does magnesium not do!

So we know magnesium is important for athletes, but it turns out that most athletes are only consuming about 60% of the magnesium they need for performance benefits on a daily basis. Make sure you’re meeting your magnesium needs by including this new magnesium supplement from GU in your daily regimen! In addition to magnesium, these supplements contain zinc, vitamin D, and vitamin K. Zinc can help reinforce your immune system to keep you healthy while vitamin D and vitamin K work with magnesium to help improve your bone health. Boost the health of your bones, muscles, and heart and get the most out of your training with these magnesium supplements!

How We Use It:

Take two capsules daily, especially during periods of intense training or competition. We recommend taking these before bed to help improve sleep quality. Magnesium can have a laxative effect when taken in high doses, so we suggest taking it after training rather than before to avoid any issues.

Excellent gift set!
Style: Skin Saviors 4 Piece Set
I purchased the Jack Black men’s skincare kit for my husband, and he absolutely loved it. The products feel high quality, smell great, and leave his skin clean, refreshed, and moisturized without being greasy. It’s a perfect combination of practical and pampering, making it an ideal gift for any man. Great value for the price and beautifully packaged. I would definitely buy this again!

It works well!
Style: Skin Saviors 4 Piece Set, Style: Skin Saviors 4 Piece Set
My fiancé was breaking out. His whole life he has just been cleaning his face with regular bar soap. I bought this for him after reading the ratings and I’m impressed. His face looks a lot clearer and it’s only been a week. He said he likes that it doesn’t make his face feel dry like the bar soap did and his blackheads and pores have also gotten so much better. There’s quite a difference! For the price of this, I’m impressed. This comes with the 4 products as shown and a sample of the beard oil they make as well.

Complete intro to skincare
Style: Skin Saviors 4 Piece Set
Cleanser: Gentle for daily use, but still leaves me feeling fresh and clean. No noticeable scent, easy to lather and rinse. This is my current favorite cleanser. Scrub: Too harsh for me. I feel like I’m raking it across my skin. Even compared to the Turbo salt scrub they make, this facial scrub feels harsh. I use it sparingly: maybe once a week. No noticeable scent, easy to use. I’d much rather exfoliate with the Glycolic ash mask or multi-acid peel pads they make. This product is not something I’d buy again; it’s good, but they make better exfoliators. SPF moisturizer: Feels very clean and light, and combines the moisturizer and SPF into one quick step, which is always nice. No noticeable scent and absorbs fast. I usually go with a different moisturizer with higher SPF though. Lip balm: Nice and simple formulation, moisturizes well and stays protecting for a good long time. The SPF is a must, and I have several tubes of Jack Black lip balm for this reason. The mint one that comes with this set is too strong for me, but at least the mintyness dissipates relatively quickly. All together, this is a complete skincare routine made up of good products. Cleanse, exfoliate, moisturize+SPF in one step, and an SPF lip balm with a minty scent to top it all off. I’d get a different exfoliating product (Jack Black glycolic mask is my favorite). If you want a complete intro to skincare with quality products in one complete set, this is a good place to start.
