 Swanson Horsetail (Natural Silica)

This Swanson formula has an important natural silica source - horsetail herb. Aside from silica, it also contains gelatin, microcrystalline cellulose (plant fiber), and magnesium stearate.

Horsetail herb is known to deliver essential minerals for healthier and stronger hair, nails, skin, and even tendons. A single bottle will not only give you sufficient daily silica per capsule (500 mg) but also provide enough silicon content to last for three months.

  • Capsule form makes it easy to take, and nutrients are quickly absorbed

Things We Didn't Like

Choosing a Silicon Supplement for Your Hair Growth Needs

Supplements, especially in tablet or capsule forms, are more convenient forms as you can bring them anywhere. That's not the only thing you should be looking for, though.

Here are other qualities you need to keep in mind when choosing a silicon supplement for healthy hair growth:

Different Silica Source​s

When it comes to using silica for hair growth, two plant sources of silica are known to be the best: bamboo and horsetail herb. Both plant sources are better than those derived from animals or artificial sources. This is because animals have already processed some of the trace minerals in their system.

However, between bamboo and horsetail, the former is hailed as the most excellent source. Horsetail herb, scientific name Equisetum arvense, is known to only contain an average of 5 to 8% organic silica.

On the other hand, Bambousa Vulgaris, the source of bamboo extract, boasts an average 70% organic silica content.​

Which Supplement Form?

Once you know you are getting the best source of silica, the next issue is how to optimize the absorption of the supplement in your system. This is something one would usually overlook.

Just because you take a supplement that does not mean your body will process it efficiently. Capsules, tablets, and soft gels are better than liquid form of supplements; however, they usually come with higher prices as well.​

Liquid supplements have a shorter shelf-life. Also storing them would have some of its components settle down at the bottom of the bottle which can be a pain in the ass and prevent you from getting all the silica from the formula.​


On average, an individual should consume between 20 to 60 milligrams of silica through food and other non-supplement sources daily. The amount of silica in our body tends to get lower with poor diet and ageing.

For obvious beneficial effects on hair growth, at least 200mg of silica needs to be consumed per day through supplements to show beneficial effects.​


If you are ready to up your game in your hair care, we recommend that you opt for Swanson Superior Herbs Bamboo Extract or Swanson Horsetail, with the former being the better choice.

Both products contain silica from excellent sources. However, as mentioned, bamboo has the highest silica content which also explains why Swanson Bamboo Extract has a lower daily dosage than Swanson Horsetail Silica.

Also, despite the differences as mentioned earlier in dosage, both can still provide above the 200 mg recommended daily dosage for silica supplements. Remember that 200 mg is the minimum recommended dosage for obvious health benefits such as increased hair growth.

Lastly, another common characteristic between the two supplements is their capsule form. Having these supplements in capsules ensures that you will be able to easily consume it and that the silica can be distributed throughout your whole body for maximum health benefits.
