Best Silica Supplements of 2025

"I wanted to incorporate silica into my daily routine to help flush out heavy metals. I add a tablespoon to my morning smoothie, and it mixes well with anything since it has no flavor. While I can't be certain it's cleansing anything, I trust the science behind silica and this brand has been solid. I've ordered it about half a dozen times and will keep stocking my cabinet with it."

"I received my product very quickly, which I appreciated. I've only been taking it for the last three weeks, so I haven't noticed a significant difference in my skin, hair, or nails yet. I'm adding 1 Tbsp. daily to a glass of water, and I'm pleased that it has no taste, so it doesn't alter the flavor of my water or juice. My hair is healthy, and I hope to see improvements in my nails in the next three months."

"This product has definitely helped my thin menopause hair to grow and become thicker. I’m a first-time user, and overall, I really like it."

"I've tried many solutions for my nails, and this is the first that has given me strong nails. Before this, they were thin and weak. It's a miracle that I finally have nails!"

"After taking this for a month, I've noticed my hair has grown, my nails are now tough, and my skin feels soft. It does exactly what it claims!"

"I documented the 28% increase in my nail growth with this product. It seems to enhance collagen production and supports joint health. I've combined it with vitamin K, MSM, and vitamin C, and I believe these supplements work together effectively."

"I initially bought this for my hair and skin, but to my surprise, my dentist noted that my jawbone loss is reversing. My skin feels significantly less dry, and I’m noticing less hair fall in the shower."

"Using this product for hair growth and skin issues has been a phenomenal experience for me. I’m really pleased with the results."

"I use this daily for aches and pains and can tell if I miss a day. It helps a bit with my energy level as well."

"A friend suggested these to me. I can't say if they work yet since I've only been using them for a month. I noticed that many reviews mention these are a 60-day supply, but if you follow the directions, it's actually only a 30-day supply. The bottle states to take one pill twice a day, which is not clear. It's puzzling that other reviews don't mention this discrepancy."

"I noticed a small growth in my nails and hair. However, I didn't experience any pain relief."

“I’ve been drinking this silica for about 2 or 3 weeks, mainly for hair growth. While I haven’t seen any changes yet, I’m committed to giving it a full 3-month trial. I appreciate that it has no taste, so I take 2 tablespoons each morning instead of the recommended one.”

“After running out of this product for a month, I truly noticed a difference. My skin lost its glow, I experienced loss of firmness, and my joints felt achy. I’ve purchased my third bottle now and can’t imagine being without it. I’m a lifelong customer!”

“This silica has made a noticeable difference in my hair quality within just 4 months. The taste is nice and neutral, which makes it easy to incorporate into my routine. I’m very pleased with the results.”

"I've found this product to be great for hair and nails. I noticed a dramatic improvement in my connective tissue health, not just cosmetic benefits. After using it for a while, I realized bruising has significantly decreased. It's convenient to take, and I appreciate that it’s in its elemental form for better absorption. I did find it a bit pricey for a mineral, but the benefits are worth it."

"After a couple of months of using this supplement, I can confidently say it's improved my energy levels. I didn't notice it at first, but when I stopped taking it, I felt exhausted. Now I make sure to add it to my water daily. It contains plant-derived silica, which is excellent for bones, hair, and nails. I plan to keep buying it and have already recommended it to friends and family as a miracle product."

"I originally rated this product five stars, but I've had to lower it to three stars. Shortly after starting, I noticed my water had a strange taste and found some dried residue near the top of the bottle. Upon inspecting, I discovered what looked like black and brown mold inside. I’m really upset because I was ingesting a tainted product and wasted a lot of money discarding most of it."

"I've been using this for a month and my nails have grown so much that I need to keep filing them down! My nails used to split, but not anymore. A coworker even commented on how strong and healthy they look. I'm definitely going to keep using it. Oh, and my hair seems a bit thicker too, but my nails are the real highlight!"

"I'm nearing the end of my first bottle. I started taking this to address my hair fall, which I've dealt with for 14 years. Surprisingly, I've noticed that my nails look really good and healthy now. No polish or nail product in my pic, just my natural nails. Usually, at this length, I have some broken or split nails, but no splits so far. I'm still waiting for results with my hair, but it does seem to shed less."

"I’m on my third bottle, giving it a fair shot for about six months. Unfortunately, I can’t say my hair has improved in terms of shininess or density. My skin seems unchanged, and my nails have started peeling and breaking recently. They are in the worst shape I've ever seen. While I hoped for at least one improvement, I won't continue after this bottle. On a positive note, it hasn’t upset my stomach. Customer service was excellent, though; they reached out to offer a refund, which was generous."

"I've been a big fan of this supplement for a long time. It is pricey but can last a long time."

"I take Super Silica every morning and after workouts to keep my lower back strong after a Lumbar Laminectomy. It also gives my skin a beautiful glow!"

"I purchased this product for my sister, who was diagnosed with stage 4 breast cancer. Now, she is cancer-free for eight years! I am grateful for this supplement."

"I have weak fingernails, and just one pill a day works wonders in making my nails grow quickly and strong."

"I used Alta Health SIL-X-Silica Tablets years ago and thought it helped my nails and hair. I’m thrilled to find it on Amazon again. After using it for over 2 months, my nails seem stronger, and I think my hair is coming in a bit thicker too. It's definitely worth trying!"

"After losing much of my hair due to anesthesia, I started taking these along with other hair vitamins, and now my hair is growing back all over my scalp."
