Astaxanthin is one of the most powerful lipophilic antioxidants yet discovered. Due to its strong anti-oxidant effects and the unique molecular structure, there are hundreds of studies have been conducted on the effectiveness and health benefits of astaxanthin. You think you know astaxanthin? or you might already taken astaxanthin? Check it here.

To the best of our knowledge, from the clinical trials using double-blind randomized controlled method, no side effects were reported at our recommended dosage (two AstaDaily per day).

Besides the health benefits, we receive and record customers reporting "side-effects" from time to time, but none of them are statistically significant and no placebo or control method were used. These side-effects are list below with estimated percentage of customers: increased bowl movement (~4%); red stool (~1%);  Irregular menstruation cycle (~0.1%); gain in weight (~0.05%).

Common questions about Iconthin AstaDaily are here.

It is recommended that you take two (2) capsules daily, preferably with a meal.

One bottle contains 60 capsules and it will last 30 days if you take 2 capsules (recommended dosage) per day.

Improving your skin, heart, and eye health is important in the long run. The benefits you feel—happier mood, maintained energy—are just bonuses when it comes to improving your long-term health. While many people feel a difference within 1-2 weeks, some don’t notice any difference and that’s okay. It’s what’s happening inside that counts.

Astaxanthin is the only carotenoid that can cross blood-brain barrier. By the time it reaches neurons—the cells in your brain that signal mood—it’s already helping your heart cells, skin cells, and more. So, be sure, it works.

It's designed for people in their 30s-50s. It doesn’t mean that it can’t help those outside that range. Theoretically, AstaDaily is suitable for anyone who is above 25 years of age and is looking to slow down the aging process or feel healthier.  

If you have a concern, we suggest checking in with a physician first and be sure it meets your specific needs.

For decades, mainstream vitamins have been formulated with low-cost ingredients. The resulting products are not only less effective but also harmful (considering the preservatives & fillers that go in).

At Iconthin, we put quality and efficacy above all. We use obsessively researched nutrients, in forms and dosages identical to those found in clinical studies. We use no traditional fillers and preservatives. Our ingredients aren’t cheap. Purchased separately, they would cost $100/month.  Astaxanthin alone would cost you $25. But our scale, our technology, and our direct-to-consumer model allows us to deliver everything your body needs in a single bottle for $48/month, or even less than $1.4 per day if you go for the 6 months pack.

Keep your bottle in a cool, dry place out of direct sunlight. Use our easy-to-carry pillbox and refill it every three days to stay on track.

The daily dosage of nutrients in AstaDaily are packed in 2, size 12 Oval gelatin softgel capsules (15mm x 10mm).

Please consult your healthcare provider before use if you are using blood-thinning medication such as prescription Heparin or Warfarin (Woumadin®). Allow 2-3 hours of separation between your prescription medication and AstaDaily.

We bring transparency to our customers and we want you to make the decision based on science and data.

Each batch of our products is tested for identity, purity, strength, and composition to ensure that we stay true to what’s claimed on the label. Not just internal tests, we rely on one of the largest third-party testing companies to test each batch, for heavy metals, pesticides residue, microbes, and other contaminants, ensuring levels fit for top quality products. We also meet safety benchmarks prescribed by the FDA’s current Good Manufacturing Practices.

By law, the FDA does not approve dietary supplements, but Health Canada does. At Iconthin, we follow regulatory requirements from Health Canada for dietary supplements.

Each product is licensed with an eight-digit Natural Product Number (NPN) which is accessible by the public through the Health Canada's database.
