Best MSM Supplements of 2025

"I think the $3 price increase is price gouging! I've used this product for months and loved it, but now I'm looking for a different distributor. Despite the price, this MSM has been effective for my knee pain and helped me stay active. I also noticed faster hair growth and improved skin tone. I appreciate the product but wish the price was more reasonable."

"I absolutely love this MSM brand! After trying many others, this one truly stands out. I started taking it while training for a marathon, and within two days, I noticed a significant reduction in joint soreness. My mom also experienced a quick relief in her hand stiffness, allowing her to stop cortisone shots. It's been a game-changer for both of us!"

"I've just begun using this MSM and find it effective. I take two doses of 2000mg each, and it works well for me. Initially, I tried three doses but had an upset stomach, so I adjusted my intake. Now, I feel great with my current dosage."

I appreciate that it works at the cellular level and promotes healing from within, rather than just masking symptoms."

"This product has been a game-changer for my daughter. After using it for a year and a half, her acne is mostly clear with only rare hormonal breakouts. She was taking 3000 mg daily but has successfully reduced to 2000 mg without losing effectiveness. Her confidence has greatly improved!"

"I started taking MSM supplements for my skin, hair, and nails. Despite being a healthy adult, my brittle nails haven't improved with anything I'd tried before, including Biotin. After a month on MSM, my nails are noticeably thicker and I haven't broken any. My skin feels more radiant too. Although the product is a bit pricey, considering it's part of my skincare routine, the investment is worth it."

"As someone who researches supplements extensively, I found it challenging to find quality MSM. I previously used MSM Crystals but was disappointed when they floated in water. After switching to Pure Encapsulations MSM, I was thrilled to find it didn't float, confirming its purity. I can't speak to the results just yet, but based on my tests, I trust this brand and believe it's worth the price."

"I was amazed when my rosacea disappeared within four days of taking Pure MSM. After about twenty days, my chronic TMJ pain vanished, and I noticed improvements in my allergies too! My skin feels incredibly soft. I did experience some queasiness initially, but after adjusting my dosage, I couldn't be happier with the results."

"I don't typically review supplements since it's tough to tell which ones work alone. However, I've noticed a significant reduction in my cholesterol thanks to Red Yeast Rice and this MSM. After a few months of taking MSM, I realized that the pain in my knees has greatly decreased. The tablets are a bit large, but the coating makes them easier to swallow for me. Overall, they are a great addition to my supplement routine."

"I purchased these MSM caplets for my Fibromyalgia. They are larger than any other caplets I've used before, which was a surprise. Unfortunately, I had a tough time swallowing them, and they felt stuck in my throat. I tried breaking one in half and using water, but it didn't help much. I prefer the capsules I usually take, as they go down much easier. After some time, I found it easier to swallow these caplets, so I adjusted my rating to 3 stars. Sorry for the long explanation!"

"I took my first pill yesterday, but it got stuck in a bad spot in my throat, which was quite uncomfortable. I suggest cutting it in half or swallowing it with food already in my mouth to ease the process next time. I don't have much experience with this supplement yet, so I can't comment on its benefits."

“In just a week, my nails improved significantly. My joints feel great even in this cold weather.”

"I've been using this for over five years to boost my hair growth and thickness, and I'm very satisfied with the results. I take 1/8 teaspoon for three months, then give my hair a break. I've also started ingesting it for pain relief, which helps a bit. It dissolves completely, so no residue, and I blend it into my smoothies. My energy levels are definitely higher with this and other herbs, and I've noticed positive effects on my skin and hair."

"I initially bought this for hair growth after reading about its benefits for joint pain and skin. Although I've only been taking it for about a week, I've noticed a decrease in knee pain within just four days. My nails grow quickly, and I've been taking 3 scoops daily in water without any side effects. There was a fluctuation in my period, but I continued taking it as advised. I'm hopeful about my hair growth results as I keep using it!"

"Since I started using this product in July, it has significantly reduced my hair shedding caused by stress. My hair has begun to grow back, but I must warn you that it can increase facial hair as well. I used to thread my upper lip once a month, and now I need to do it every 20 days. Additionally, I've switched to washing my hair twice a week, which has helped with the hair loss, and I take it with vitamin C for better results."

"I've been using this MSM daily for a month. I take about 1/2 tsp in the morning and another at night. My hair, which I cut too short, has grown about an inch already! My nails are thick, smooth, and shiny. I can't speak to the effects on joints, but for hair and nails, this product is top-notch. I mix it in lukewarm water, and it hardly tastes like anything!"

"After using this MSM for a while, I noticed significant improvements in my overall well-being. My joint health has improved, and my skin looks clearer. The packaging is excellent, ensuring freshness. However, the taste is quite strong. I find mixing it with juice helps, but it's something to keep in mind."

"I bought this MSM after hearing about it on TikTok. It has dramatically changed my life. I had a boxing injury causing severe wrist pain, but after taking this, my pain dropped from 10 to a 2. My hair is growing thicker, and I've noticed much less hair loss. This product is a game changer for overall health!"
