THE RESULTS
High praise for this little powerhouse of a supplement!
We were hard-pressed to find any shortcomings with this product. After a brief period of use, we saw a marked improvement in our skin – it looked significantly healthier and more vibrant.
But the benefits of Astaxanthin didn’t stop there. Beyond the visual enhancements, we felt a noticeable shift in our energy levels. We hadn’t been fully aware of our energy deficit until we experienced the revitalizing effects of this supplement.
We also observed a considerable improvement in our digestion and gut health, largely attributable to the all-natural ingredients and added superfood extracts. And since Astaxanthin is gluten-free, it further helps to curb inflammation and support a healthier digestive system.
Moreover, Astaxanthin’s properties as a powerful antioxidant meant it was working hard to protect our cells from harmful free radicals, contributing to overall health and anti-ageing benefits.
These supplements are nothing short of astounding! Their effectiveness is unrivalled, easily making them our top choice of supplement!

THE RESULTS
This is a brand that has been around a while, but we’ve never tried their products, so we were looking forward to putting it to the test.
This product includes a lot of natural ingredients. The brand claim that their Astaxanthin is naturally grown in Hawaii and includes other natural ingredients such as safflower oil and purified water. We were also happy to note that the product is gluten and lactose free which helps to promote a healthy gut.
Whilst we were happy with the ingredients, we were not happy with the size of the gel capsules. These were beyond big and very difficult to swallow. In fact they were so big to swallow that it almost felt impossible and was very uncomfortable.
After finally swallowing the gel caps, we did feel some improvements, however, we did suffer with a bit of sickness consistently over the testing period.

THE BOTTOM LINE
Whilst we saw small initial improvements, these supplements didn’t quite get us to our goal, and we did suffer with some sickness during the testing period. We also found the capsule itself rather difficult to swallow.

THE RESULTS
Nature City have a variety of different supplements available, so when we saw True Asta (Astaxanthin Supplement) we were intrigued.
We were initially impressed with the ingredients; everything was natural and there were no harmful synthetic ingredients. We were also pleased to see that this product was gluten and soy free which helps to promote a healthy gut and means it is safe for anyone who suffers with those allergies.
However, we did suffer from some mild side effects, including stomach discomfort and a couple of headaches. We did see an improvement in our skin, but the stomach discomfort did let us down.

Almost there! But not quite. Whilst we did see an initial improvement, we didn’t appreciate the stomach discomfort and headaches. Whilst not intense or severe, we have tried supplements that didn’t deliver the same side effects so did feel a bit let down.

THE RESULTS
When we saw that this product offered AstaPure microalgae, which wasn’t included in a lot of other brands we tested, we had to give it a try to see whether it made much difference.
We tried the product over a period of a few weeks. We used as directed and at first felt that there may be some improvements, but we didn’t have an extra boost of energy or feel great improvement to our health, and in fact suffered a few side effects.
Something that also put us off was the initial smell of the product when opening the bottle. It smelled strongly of chemicals which may just be down to the manufacturing.
Whilst we appreciate that this brand tried to add something new to the mix, we didn’t feel that it fully delivered.

THE RESULTS
On testing the product, we initially found great results, with our skin improving massively in a short time.
However, then came the side effects. Whilst they were mild and not intrusive enough to distract us from our day, they did cause us some discomfort. We were also disappointed to note that the product is not suitable for vegans, so this isn’t for everyone.
