Backed by GMP and ISO-certified testing, this unflavored, vegan-friendly supplement supports over 300 enzymatic reactions, helping busy professionals maintain peak metabolic and neurological performance. ## Description Supports Energy Production* Critical for Enzyme Function* Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization.* It is a required cofactor for an estimated 300 enzymes.* Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism.* Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland.* Review: Magnesium, necessary for life - Magnesium is the most important mineral in your body. Lose your magnesium and you lose your life. Magnesium is a vital catalyst in enzyme activity, especially the activity of those enzymes involved in energy production. It also assists in calcium and potassium uptake. A deficiency of magnesium interferes with the transmission of nerve and muscle impulses, causing irritability and nervousness. Supplementing the diet with magnesium can help prevent depression, dizziness, muscle weakness and twitching, and premenstral syndrome (PMS), and also aids in maintaining the body's proper pH balance and normal body temperature. Magnesium is necessary to prevent the calcification of soft tissue. This essential mineral protects the arterial linings from stress caused by sudden blood pressure changes, and plays a role in the formation of bone and in carbohydrate and mineral metabolism. Magnesium is a factor in helping to prevent cardiovascular disease, osteoporosis,kidney stones, chronic fatigue, insomnia, irritable bowel syndrone, and a multiple of other diseases brought on by a lack of this essential mineral. I have taken 1/4 of a teaspoon of magnesium in a 8 oz. glass of water twice daily since 1989 for hypertension and it helps me maintain a normal blood pressure. Magnesium is most inexpensive, miracle mineral you will ever take. I highly recommend it.

Bigger than say an advil soft gel?** A: They are ridiculously huge. I almost choked many times. I literally was afraid I could die taking these. They are effective, but I am finding something else because they are way too big. Cutting them in half does not work, as the rough end can then cut your throat on the way down. This is the biggest pill I've ever seen. This is in reference to the 200 mg. I will be trying either the capsules, soft gel or another brand next because these are way too big. **Q: Does this contain any dairy products ?** A: It does not appear to. Ingredient list reveals vegitable sources and coatings but no mention of anything dairy. It does state its manufactured in a GMP facility that does produce items containg dairy, but this particular product does not. **Q: Will it help with constipation...** A: Yes. It works great for me. I have never been "regular" that I can remember. I starting taking 200 mg every night, and I am finally "going" every day, and sometimes multiple times! I do take calcium w/ magnesium in the morning, but apparently that was not quite enough. With this added 200 mg, it seems to be the right amount for me. **Q: At the top says: Serving size 1/4 teaspoon (700mg) but below is says 400 mg per serv. If there are no other ingredients shouldn't those be the same?** A: I cannot explain why it says that and it is definitely confusing. I understood it as 1/4 is a serving and each serving has 400mg. What the 700mg is, I don't know, but it has to mean something. On a separate note, the powder doesn't dissolve well in water so unless you are using disposable cups, the powder can be tough to clean from a glass. I switched back to mag pills. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Magnesium, necessary for life *by R***N on October 30, 2012* Magnesium is the most important mineral in your body.

I have been using these for quite a while now, the result is obvious to me, however, it is very difficult to explain. I intend to continue to use these products, using caution to stay within the suggested dosages. ## Frequently Bought Together - NOW Foods Supplements, Magnesium Oxide, Enzyme Function*, Nervous System Support*, 8-Ounce - NOW Foods Supplements, Potassium Chloride Powder, Certified Non-GMO, Essential Mineral*, 8-Ounce - NOW Foods Supplements, Calcium Carbonate Powder, High Percentage of Calcium, Supports Bone Health*, 12-Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/3350933-now-foods-supplements-magnesium-oxide-enzyme-function-nervous-system-support](https://www.desertcart.pt/products/3350933-now-foods-supplements-magnesium-oxide-enzyme-function-nervous-system-support) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-05*
