It quickly helps reduce my scar tissue muscle pain. ### ⭐⭐⭐⭐⭐ More Than I Could Have Ever Expected!! *by V***K on January 27, 2017* I cannot say enough about this product!! I am a very overweight person with a few chronic health problems and I heard all the wonderful things about MSM online and decided to take the plunge and order some. Three months ago I started taking it and the results are absolutely staggering. I have not had this much energy in years. I feel like I'm young again and I wake up everyday ready to go. My heartburn stopped completely, my skin looks healthier, my energy levels are so high I don't even want to go to bed at night, and my joints, especially my knees, ache way less. In fact, if I skip a morning taking it, I immeditely notice.I found the key for me was to start with a smaller dose than recommended. The first time I took it, I used a teaspoon and I became very nauseous so I started with a 1/4 teaspoon and worked my way up over two and half weeks to a full teaspoon every morning. I also found that their recommendation for filtered water is incredibly important. If I don't use it, I notice that my energy is down because the supplement isn't working as well. I mix it with about two ounces of cranberry juice in a double shot glass because that masks the flavor pretty well (the one downside to the supplement is that it tastes disgusting, but I guess that's the payoff) and I drink that and then chase it with another six ounces of water. I also found that if it makes my stomach queesy, eating some breakfast immediately afterwards quells the feeling.I know that the product makes the body go through a sort of detox and my first week, I peed like crazy. The first three days, I peed like every hour at least and more urine than I even thought possible. It actually freaked me out, but then after a few days I felt so good I just continued. Figured I'd just throw this in there in case anyone else had the same thing happen to them.Lastly, I know some take it at bedtime because the product recommends that, but I haven't tried yet because I'm worried I won't be able to sleep. Either way, good luck and I hope it works for you as well as it has for me! --- ## 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.th/products/7627952-7-lights-sulfur-defense-opti-msm-99-9-pure-msm](https://www.desertcart.co.th/products/7627952-7-lights-sulfur-defense-opti-msm-99-9-pure-msm) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
