Horsetail Extract (4:1) 500mg by EssentialSeries is a food supplement based on herbal extract of Equisetum arvense, 4 times more concentrated than the original raw material, vitamin C and biotin.
This natural horsetail extract provides 1000mg per daily dose, equivalent to 4,000mg of native Equisetum arvense.
In our capsules we have used Horsetail with a high 4:1 extraction ratio, thus achieving a much more concentrated product.
Each unit of Horsetail extract (4:1) is equivalent to 4 units of naturally occurring Equisetum arvense herbs.

Horsetail extract (4:1) is a food supplement suitable for vegetarian and vegan diets.
No catalyst ingredients of animal origin have been used during the treatment process of the raw material used.
We have also used HPMC as a glazing agent, a polymer derived from vegetable cellulose, 100% suitable for vegans, thus avoiding the traditional use of gelatine in the manufacture of capsules.
Why not combine this product with other products from our EssentialSeries line such as Turmeric Extract; or products as Evodren by SportSeries?

Meh
Santi | 19/05/2023
The truth is that I expected something more. I cannot evaluate the quality of the product. I simply did not get the diuretic effect I expected.
