What Transparent Labs says
Overview Supplementing with the mineral Magnesium is more than just wishful thinking, it’s likely the most underrated supplement in the vitamin and mineral industry. Magnesium isn’t a ‘the more the merrier’ type supplement like protein. Instead, it’s a case of proactively staving off deficiency of this mineral. A deficiency which an estimated 80% of Americans are subject to and don’t even know it. Got a bad diet? Taking magnesium daily should be your strategy. Going through an intense boot camp? Taking magnesium for this period should be your tactic. Ingredient Profile Magnesium Bisglycinate | 300mg How to Use As a dietary supplement, take 3 capsules with or without a meal once or twice a day, or as directed by your physician. FAQs Q. What Magnesium should you take? Well, if you’re familiar with our one-of-a-kind ZMO supplement (Zinc, Magnesium, and Oyster) then you’ll know that not all magnesium supplements are the same! The most common form of magnesium on health store shelves is magnesium oxide, which is in fact, one of the worst types for an athlete to take. This is because oxidized minerals, especially magnesium, have an extremely difficult time entering the body. This ‘difficulty’ paired with magnesium’s muscle-relaxing effects is why magnesium oxide is also often the main ingredient in laxative supplements. Surely, not what you want to take before leg day. Q. What form should you be taking? Magnesium Bisglycinate. We recommend the highly bioavailable and non-laxative Magnesium Bisglycinate. It isn’t cheap like magnesium oxide, but neither are any of the ingredients t
Frequently Asked Questions (from the seller's page)
How much magnesium do I need daily? The recommended daily allowance (RDA) for magnesium varies throughout the lifespan and between sexes. Adult males typically require more magnesium than adult females (400 mg per day vs. 310 mg per day, respectively), and pregnant/lactating women generally need more magnesium, upwards of 350 mg per day, than women who aren't carrying or nursing. What Is elemental magnesium? Elemental magnesium is the amount of magnesium itself in a magnesium supplement. It may or may not be the same as the dose listed next to the magnesium ingredient(s) in a supplement formula. For example, magnesium citrate — usually a 1:1 ratio of magnesium to citric acid — only provides about 11% elemental magnesium by mass. What does magnesium bisglycinate do? Magnesium bisglycinate provides magnesium in a chelated form, which enhances absorption and gastrointestinal tolerance. Magnesium itself is an essential mineral involved in hundreds of enzymatic reactions, including those regulating neuromuscular activity, energy metabolism, protein synthesis, and neurotransmitter function. The bisglycinate form is bound to glycine, an amino acid that may support relaxation and reduce the excitability of the nervous system. This combination makes it particularly useful for supporting sleep quality, muscle recovery, and stress resilience. What time of day should I take magnesium bisgl
