Very good product

This Swiss-made supplement offers consistent, reliable quality, giving me peace of mind. The tablet design is very convenient to take, eliminating any difficulty swallowing. After consistent use, I've noticed a noticeable increase in energy, and I'm no longer as easily fatigued. Even better, my blood test results showed improvement, which reassures me of the product's effectiveness. If you're looking for a supplement that effectively boosts your energy and overall well-being, this product is definitely worth a try.

They’re an easy and convenient way to add iron to my daily routine, and I like that they come in a vegan formula rather than a traditional iron supplement.

Favourite!

The ingredients and quality of this supplement are amazing! I do love the small package size of this product! I always felt the Strath products I can easily absorb and it helps me with my gut and constipation issues. The taste is like caramel 😋 My digestion can feel the benefit for sure!

excellent quality

I really like the brand, it was recommended by my naturopath, it's very complete, the only drawback is that it's large, unsuitable for children or those who are sensual when swallowing something large. Otherwise, it's okay, now it's just a matter of waiting to repeat the tests and see the results.

Since the koji iron supplement was discontinued, I bought this instead. It doesn't have a metallic taste or flavor, and although the size isn't small, it's easy to swallow.

It works!

I had high expectations for this brand's supplements because they are high quality, but they are also great for bacterial activity and iron.

A great way to replenish iron

This product provides a natural way to support your iron levels. Yeasts are given iron fumarate, which they consume and convert the iron in to an organic, digestible for humans form. Definitely a worthwhile investment if you need to restore iron levels, especially if you're a woman.

Probiotic for gut health

Good natural ingredients. The tablet size is slightly larger than usual. The packaging is convenient. It's good for digestion. Contains iron.
