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. ## 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.co.uk/products/265100963-now-supplements-magnesium-oxide-8-ounce](https://www.desertcart.co.uk/products/265100963-now-supplements-magnesium-oxide-8-ounce) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
