Best Natural MSM Supplements of 2025

"I bought this product because I learned that most bacterial infections can't survive in alkaline environments. After successfully using calcium in the past, I switched to sulfur and found it worked wonders for my serious urinary tract infection—I even tripled the dose. It not only served my initial purpose but also offered unexpected benefits like removing calcium deposits from my arteries and improving my skin's elasticity. I’ve noticed a significant reduction in wrinkles, especially around my eyes and neck. At 63, I feel I look 15 years younger than my younger brother, which he definitely doesn't appreciate! Plus, I’ve started regrowing hair, albeit thinly. I can’t say this brand is better than others, but it works fantastically for me."

"I really appreciate that the MSM comes in capsules, making it easy to take. The crystal form can be quite bitter, but this product offers so many health benefits that it's worth it. Plus, I love that I received three bottles at a very reasonable price!"

"Using this product for years, I find the capsule form allows for precise dosing, ensuring I maintain exact amounts of MSM in my system. It's been a huge plus for me, and I’m grateful for its effectiveness!"

"I use this to help with inflammation and control my psoriasis on my hands and feet."

"A friend brought this to me in Mexico, but when I opened it, all the capsules were stuck together. There was no moisture packet inside, and I ended up with a powdery mess on my counter. I wish I could return it, but I can't while I'm here for 6 months."

"After trying numerous supplements for my arthritis, this one has made all the difference. I now take significantly less Tylenol and can handle weather changes much better than before."

“This product is a daily essential for my hip pain. I feel so much better when I take it!”

"I believe that a $3 increase per bottle is a clear case of price gouging! After using it for months at a lower price, I'm not happy about this change. While I genuinely like the product, I may look for a different distributor in the future. I did find that this serves as an antioxidant and detoxifier, but some individuals may experience initial reactions. It's essential to take it with food and adjust the dosage. Despite the price, this product has significantly improved my pain levels and even helped my dog's allergies!"

"I absolutely love this MSM brand! After trying numerous others, I always come back to this one because it works wonders for me. When I was training for a marathon, I noticed the effects within days—no more sore joints! I also sent a bottle to my mom, who was suffering from severe joint pain, and she experienced relief in just two days. This MSM has truly changed her life, allowing her to stop painful cortisone shots. It's a must-have for both of us!"

"I just started using this product and find it effective. I take 2 doses of 2000mg MSM in the morning and at night, making sure to have it after eating. I learned the hard way that taking it on an empty stomach can upset my stomach. After adjusting my dosage, I feel great with 4000mg a day!"

"I find that MSM makes me feel amazing! I started with a half teaspoon daily and gradually increased it. After reaching around 20,000-30,000mg, I felt incredible. This brand is high quality and fairly priced."

"Having tried several MSM products, I prefer this one for its purity and affordability. Its texture is great, and it dissolves easily in my smoothies. I love the eco-friendly packaging too!"

"I chose this MSM for my arthritis pain and was surprised by its bitterness at first. However, dissolving it in hot water helped. Within two weeks, my thumb pain significantly decreased. I appreciate the large supply and will consider repurchasing."

"After just two days, I felt magnificently better. My knees, in particular, were much improved, allowing me to go up and down the stairs with less pain. I plan to continue taking it, although it is definitely a 'horse pill'. I wish it could be in gel caps. Remember, you need to take it three times a day for the best effect!"

"I was initially skeptical about MSM, but after a friend insisted I try it for my joint pain and allergies, I decided to give it a shot. After a few weeks, I noticed my hair growing super fast and feeling much stronger, which is a big deal for me since I have thyroid issues. My nails are also growing faster. I’m still unsure if it’s helping my joint pain and allergies, but I’m going to stick with it for now, especially since it has no side effects."

"As someone with 4a/b curly hair, I recently shaved my head after a mishap. Since I started taking this supplement along with bamboo silica, I've noticed my edges have grown down to my eyelashes and my hair is growing much faster than before. I can’t say for sure if it’s just this product or the combination, but I’m thrilled with the results so far!"

"This MSM supplement was recommended by my doctor for its benefits concerning joints, skin, hair, and nails. After taking it, I can feel a difference in my joints and my nails seem stronger. I do find the pills quite large, so I cut them in half to make it easier to swallow."

"This is a great buy! I use these for myself and my cats, and we all find the product to be excellent."

"It's a safe and clean supplement. Natural Factors offers competitive pricing as well."

"I've been using this MSM daily for a month, taking about 1/2 tsp in the morning and another at night. I cut my hair too short and desired fast growth—it’s grown about an inch already! My nails are thick, smooth, and shiny. I can't comment on joint health, but for hair and nails, this product is top-notch! I mix my dose in lukewarm filtered water, and it really doesn’t taste like much. I'm thrilled with this product!"

"After trying this MSM as part of a heavy metal detox, I've had excellent results. I lost over 10 pounds and dealt with inflammation issues.

I highly recommend this for overall health benefits!"
