As long as suggested serving sizes are adhered to, Horsetail Extract should cause no unwanted side effects. However, consuming Horsetail Extract orally may result in a decrease in the body’s levels of Thiamine. Taking this side effect into consideration, it may be a good idea to take a supplement containing Vitamin B1 or a B-vitamin support structure in order to balance this out.

Anyone taking Lithium should not use this product. Those that have diabetes or kidney problems and women who are pregnant or nursing are cautioned against taking Horsetail Extract.


The taste of Horsetail Extract is often described as bland or possibly bitter. It can be mixed into a variety of drinks and can even be used as a tea. It can also be put into capsules and taken orally as well.

The best Horsetail Extract Powder
I love this stuff and can really tell it's helping with my hair, skin and nails. Everything I have ever gotten from B.S has always been top notch. Slowly replacing all supplements I use to B.S.*

Good feeling
I feel good right away after every dose of this Horsetail Extract.
I take it mainly as many others for the high silica content.
Arrived quickly. Thank you Bulk!

Beaware horsetail contains thiaminase, an enzyme that breaks down the B1 vitamin (thiamine) and also contains trace amounts of nicotine.

horsetail extract
I bought this to thicken my hair.I've only been using it for a couple of weeks so have not seen any change as yet.*

Great for Silica
Horsetail is great for obtaining high dosage of silica in the diet, and these powdered form supplements provide the RDA and more. (Too early to comment on the effectiveness of this particular batch, but shipping etc was good and arrived pretty quickly).

The only potential issue with Bulk Supplements is the resealable packaging they use which, although great for shipping in terms of size, does tend to open up (the seal) by the time it arrives (so part of the powder slips out when you tear open the package), and some seals on the packets don't re-seal easily - I am not sure how much of an effect this has on the quality if oxygen and hydrogen are getting into the products if they are not sealed??*

good bladder health
I received this for free for buying another product. Its too soon to see any real effect but my bladder sure is working. *

Can tell a difference already
(I received a sample of the horsetail extract in exchange for my honest review.)

I was excited to see that Bulk Supplements had the horsetail extract. I've taken a "hair, skin, nails" multivitamin with trace amounts of horsetail in it on and off for years, but it's expensive and I wanted to switch to something less expensive, then take horsetail separately. This is perfect. The taste, to be honest, is pretty bad. But I just swallow it quick with some juice or water and get it down. And I can take it in a larger dose much less expensively than with the multivitamin.

I haven't seen any hair changes, since I've only been taking this a few days. But the bladder health benefits are real, and I do notice those with this larger dose (not noticeable with the multivitamin). I've no doubt that the bone health benefits are also real, even if I can't tell yet. And as always, Bulk Supplements' quality is top notch. *

Horsetail Extract
This was my first order from Bulk Supplements and was so pleased when my order arrived so promptly. The security of the packaging was impressive. I just recently learned of the importance of silica to retaining the density of my bones and am most anxious to supplement the calcium that I am now taking. It is too soon to report results, but I am most hopeful .*

Excellent Quality Horsetail Extract!
Before making my purchase of a horsetail supplement, I researched and compared many different brands and forms. After comparing the horsetail extract to the others, the choice became clear! After receiving my order, I was even more pleased to see the high quality resealable, moisture and light proof packaging! Moreover, the actual horsetail extract powder is extremely good quality!! Though I have only been using this product for a few days, I am VERY pleased with my purchase and will definitely be ordering more supplements from! *

Horsetail Extract
I am truly impressed with everything that I have ordered from Bulk Supplements over the past several weeks. The purity and effectiveness of each of the products that I have received have been outstanding.
At age 46 I had a bone density test done and found out that I had osteopenia. I was told to take LOTS of calcium by my OBGYN. I am so glad that I didn't just stick to calcium supplements over that past several years. I later found that I needed get my D-3 levels up and also include Magnesium Glycinate (which I now get from Bulk Supplements). I also learned that getting enough of a natural form of silica was even more crucial than the calcium for my bones and that horsetail (in the right form and preparation) is one of the most richest forms of silica. I researched and found that Bulk Supplements Horsetail extract suppliies 70 mg of Organic silica per 1000 mg dosage. I ordered this product and I am thrilled with it! I split it into two daily doses for best absorption-1/8 tsp twice a day (444 mg per 1/8 tsp). I mix the this horsetail extract powder with my magnesium glycinate powder and swallow it all at once with a glass of water. I just do it straight up. It does not have a bad taste to me at all. This horsetail extract powder will dissolve quite easily- so it can be mixed into liquids or drinks. So excited to see how this product will work for me! Love Bulk Supplements Products!!!*

Bought this a year ago for my skin, hair, and nails, but instead got full-blast urinary health
The following is a list of clinical trials, most double-blinded and placebo-controlled, recorded at the National Medical Library, MEDLINE, as abstracted by GreenMedInfo for horsetail and silica (orthosilicic acid):

1. Horsetail extracts exhibit blood sugar lowering effects in type 2 diabetes.
2. A proprietary blend of herbs [Aspen, Horsetail, Pipsissewa, Pulsatilla pratensis, Wheat Bran] suppresses bladder oxidative stress and inflammation in rat and rabbit models of partial bladder outlet obstruction and in patients with benign prostatic hyperplasia.
3. Various herbs [Burdock, Dandelion, Horsetail, Lithospermum officinale, Silene saxifraga, Uva Ursi (aka Bearberry), Verbena officinalis] may have a therapeutic role in preventing and treating kidney and bladder stone formation.
4. Equisetum [horsetail] has anticonvulsant and sedative properties.
5. Equisetum has hepatoprotective actions.
6. Equisetum has lipid-lowering properties.
7. Choline-stabilized orthosilicic acid has a positive effect on skin surface and skin mechanical properties, and on brittleness of hair and nails.
8. Choline-stabilized orthosilicic acid improves tensile strength and morphology in women with fine hair.
9. Orthosilicic acid has therapeutic value in the treatment of osteopenia and osteoporosis.
10. Silicic acid may reduce the body burden of aluminium in Alzheimer's patients.

I originally bought this horsetail extract because my nails have longitudinal ridges, hair was a little thin, and the skin seemed developmentally weak, that is, dark spots all my life. "Constellations" they were called in high school. I have bought a lot of things and taken them daily to improve this, such as:
1. Astaxanthin, 12mg, which lightens the skin and dark spots, both, while changing the color slightly to a better-looking orange-pinkish-brown tint, hair color, too, has made my skin absolutely bullet-proof with respect to sunburn.
2. Biotin, 10,000 mcg, to help skin, nails, and hair, has doubled the rate of hair growth as measured by haircut frequency, but the hair is still a little thin.
3. The longitudinal ridges on the nails are still there. Nail brittleness, breaking, chipping, splitting is still there, too.
4. Resveratrol, 250 mg, and n-acetyl-l-cysteine (NAC), 1400 mg daily, may also have helped the skin.
5. Methylsulfonylmethane (MSM), 5000 mg, is 34% sulphur to produce disulfide bonds for collagen, keratin for skin, nails, and hair.
6. Green tea extract, 250 mg, pine bark extract, 400 mg, grape seed extract, 2000 mg, has almost certainly improved my skin.
7. Vitamins A, 5000 IU, B-complex, 25 mg everything, C, 4000 mg, D, 5000 IU plus daily sun, and E, 246 IU, l-lysine HCL, 680 mg, l-proline, 2000 mg, hyaluronic acid, 50 mg, lutein, 24 mg, rutin, 65 mg, quercetin, 25 mg, selenium, 200 mcg, zinc, 20 mg, ubiquinol, 100 mg, alpha lipoic acid, 200 mg, fish oil, 1200 mg EPA, 600 mg DHA, and krill oil, 500 mg, have all presumably helped the skin.
8. DMAE (dimethylaminoethanol) bitartrate, 1400 mg daily, plus occasional skin cream (lemongrass) with 3% DMAE added should have gotten rid of lipofuscin from dark spots. Does not seem to be working very well although DMAE has other big benefits.

The improvement in urinary health was completely unexpected. But then I noticed that I could drink large quantities of water at night, not ever have to get up at night, and even then in the morning not have to go to the bathroom. I could hold vast quantities without even thinking about it. Then, it was like a cataract. I have been taking some other supplements daily that may have helped this:

1. Zinc, 20 mg, pomegranate extract, 50 mg, milk thistle, 250 mg, 95% curcuminoid extract, 500 mg, beta sitosterol, 1000mg, should all have have helped with bladder and prostate health. But it is the horsetail extract that has properties that are specifically expected to help with urinary flow rate. I had been taking the BulkSupplements minimum recommended amount of 440 mg daily.
2. I have been eating a lot of organic celery lately for the last few weeks for the purpose of building up nitric oxide levels to improve athletic performance. Celery kills bladder bacteria, is a diuretic, and is a rich source of silica, as well, just like horsetail.
3. I have been eating some kind of probiotic food everyday such as Bragg's raw apple cider vinegar, raw sauerkraut, and kefir.*
