Great

Great quality, I took this supplement to improve overall health and my immune system. As I have problems with my veins, I noticed improvement while I was taking it. Clean ingredients, I trust swanson. Good antioxidant as it has many other benefits. Large packaging, good for 60 says if you take 1 capsule per day.

Excellent longevity, potential anti aging, antioxidant capabilities!

Having looked at the potential of brown seaweed extract in terms of studies done over many decades, some of which look at one of the highest longevity locations on the planet, Okinawa Japan, a region with some of the most 100+ year old people, who consume this compound in their daily diets of locally grown amazing seaweed varieties, I was compelled to take this supplement several times over the past 15 years. One of the pioneers of juicing and raw food diets, Normal Walker, who lived to be 99 and was born in the 1880's, ate seaweed, among other specific raw foods, daily, and despite not knowing about the particular compounds within seaweed extract, people who consume it regularly, usually report that they feel better from the regular consumption of this god given food and plant. Definitely worth trying, and Swanson is a trusted company with a reasonably priced version of this product. Highly recommend!!! Your outer appearance and inner feeling of wellness have a chance of improving with this product.

Loving my iHerb check out spree!

I am so glad that I came across the iHerb app. Living in the Philippines, I have limited choices as to legitimate herbal product sellers both online and in-person. Now, I can simply browse the app and look for the supplements that suits me best! The quality is at par with what I expect. I'm hoping this will help me heal my body. the ingredients are written clearly on the label including the manufacturing date and BBF date which I appreciate. The size is just right for the value. And the antioxidants in this supplements is full packed!

The ingredients are clean, the quality is high, the pills are a good size, I'm using the dosage recommended by my doctor, the benefit is reasonable considering the quality, and the taste is unflavored, which is nice.

Good for your health.

I purchased a few different brands of fucoidan and they work pretty much the same, I think they boost my immune system.

Good Product

I had passed a bottle to a friend and he said that this product is good. He can feel the difference in the body after about a week. Good to buy again.
