Astadaily vs Natural Factors Astaxanthin

Both Astadaily and Natural Factors are Canadian supplement brands offering natural astaxanthin derived from microalgae. Both provide Health Canada-licensed products and oil-based softgels designed to support the absorption of this fat-soluble carotenoid. However, they differ significantly in ingredient sourcing transparency, cultivation and extraction disclosure, manufacturing claims, dietary compatibility, testing documentation, and packaging.

Astadaily Astaxanthin uses AlgaeAsta® natural astaxanthin cultivated in a fully enclosed bioreactor and extracted using supercritical CO₂ technology. It is manufactured in Canada under GMP-certified conditions, independently tested across approximately 80 quality and safety parameters, and packaged in individually sealed blister packs.

Natural Factors Astaxanthin provides naturally sourced microalgae astaxanthin in 6 mg and 12 mg softgels with flaxseed oil. However, the product does not clearly identify the original astaxanthin supplier, cultivation system, or extraction process. Its softgel contains gelatin and is therefore not vegan. Product packaging that states “packaged in Canada” confirms where the product was packaged, but does not necessarily establish that the softgels themselves were manufactured in Canada. Natural Factors currently lists both 6 mg and 12 mg astaxanthin products.

Quick Comparison

1. Astaxanthin Source and Production Transparency

The quality of an astaxanthin supplement begins with how the microalgae are cultivated and processed.

Astadaily clearly identifies its ingredient as AlgaeAsta®, derived from Haematococcus pluvialis. The algae are cultivated in a fully enclosed bioreactor where growing conditions can be closely controlled without relying on seasonal weather or outdoor sunlight.

Astadaily also discloses the use of supercritical CO₂ extraction, an established solvent-free extraction method that uses carbon dioxide under controlled pressure and temperature.

Natural Factors describes its astaxanthin as naturally sourced from microalgae, but does not prominently identify the original ingredient supplier. Public product information also does not clearly explain the cultivation system or extraction method used to produce the astaxanthin oil.

The absence of these details does not prove that the ingredient is lower quality. However, it gives consumers less information for assessing its production history and traceability.

Winner: Astadaily

2. Made in Canada vs Packaged in Canada

Both companies are Canadian brands, but Canadian brand ownership does not automatically mean that every product is manufactured domestically.

Astadaily states that its finished supplement is made in Canada in GMP-certified facilities, providing a clear claim regarding finished-product manufacturing.

Natural Factors packaging states that the product is packaged in Canada. This indicates that packaging took place domestically, but the wording is not equivalent to “Made in Canada” and does not, by itself, identify where the astaxanthin softgels were manufactured.

This distinction matters to consumers specifically looking for supplements whose finished dosage form is manufactured in Canada rather than only bottled or packaged domestically.

Winner: Astadaily

3. Quality Testing and Transparency

A premium astaxanthin supplement should be tested for both potency and safety.

Astadaily performs independent third-party testing across approximately 80 quality and safety parameters, including astaxanthin potency, heavy metals, microbiological contamination, pesticide residues, and other relevant specifications. Astaxanthin concentration is measured using HPLC, which separates astaxanthin from related carotenoids before quantification.

Natural Factors is a long-established supplement manufacturer with an extensive quality-control program across its product portfolio. However, comprehensive batch-specific third-party reports for its astaxanthin product are not readily available for consumers to review publicly.

The difference is therefore not simply whether quality control occurs, but whether consumers can access detailed documentation concerning the specific astaxanthin product they are purchasing.

Winner: Astadaily

4. Vegan Formula and Carrier Oil

Both products deliver astaxanthin in an oil-based softgel, an appropriate format for a fat-soluble carotenoid.

Natural Factors uses flaxseed oil as its carrier. However, its softgel shell contains gelatin, glycerin, and water, making the product unsuitable for vegans and most vegetarians.

Astadaily uses sunflower oil and a vegan softgel shell. Its Astaxanthin Pure formula is also Halal-certified, making it compatible with a broader range of dietary and religious preferences.

Consumers who do not avoid animal-derived gelatin may find either formula suitable. Those specifically seeking vegan astaxanthin will find Astadaily to be the appropriate option.

Winner: Astadaily

5. Dosage Options and Convenience

Natural Factors offers both 6 mg and 12 mg astaxanthin softgels. The 12 mg product allows consumers to obtain a higher daily amount from one softgel, which can be convenient for those who prefer a single-capsule routine.

Astadaily provides 6 mg per softgel, allowing consumers to take one softgel for 6 mg or two for a 12 mg daily serving. This provides flexibility without requiring separate products for different serving levels.

Natural Factors has an advantage for consumers who specifically prefer one 12 mg softgel. Astadaily offers greater flexibility for those who may alternate between 6 mg and 12 mg servings.

Winner for single-softgel 12 mg dosage: Natural Factors

Winner for flexible dosing: Astadaily

6. Packaging and Freshness Protection

Astaxanthin is sensitive to oxygen, moisture, light, and heat, making packaging an important quality consideration.

Astadaily places every softgel in an individually sealed blister cavity. Unused doses remain protected until they are removed, helping minimize repeated exposure throughout the product’s shelf life.

Natural Factors uses a conventional plastic bottle. Bottles are economical, familiar, and easy to store, but opening the container exposes all remaining softgels to fresh air and humidity.

For consumers prioritizing individual dose protection, travel convenience, and freshness from the first softgel to the last, blister packaging provides a meaningful advantage.

Winner: Astadaily

7. Brand Recognition and Specialization

Natural Factors is one of Canada’s best-known natural health product companies. It offers a broad portfolio of vitamins, minerals, herbs, antioxidants, and specialty supplements and benefits from extensive distribution through pharmacies, health stores, and online retailers.

Astadaily is a newer and more specialized brand developed by Iconthin Biotech. Its focus is specifically on astaxanthin and microalgae technology, including cultivation, extraction, analytical testing, formulation, and finished-product development.

Natural Factors has the advantage in overall brand recognition and retail availability. Astadaily offers deeper specialization within the astaxanthin category.

Which Canadian Astaxanthin Supplement Is Better?

Natural Factors Astaxanthin is a practical choice for consumers who value an established Canadian supplement brand, broad retail availability, flaxseed oil, and a choice between 6 mg and 12 mg strengths. Its 12 mg product may be especially convenient for consumers who prefer a single daily softgel.

However, Natural Factors does not clearly disclose the original astaxanthin supplier, cultivation system, or extraction method. The product is described as packaged in Canada rather than clearly identified as made in Canada, and its gelatin softgel is not suitable for vegans.

Astadaily provides greater transparency through closed bioreactor cultivation, supercritical CO₂ extraction, HPLC potency measurement, approximately 80 third-party quality and safety tests, Canadian GMP manufacturing, vegan and Halal-certified softgels, and individually sealed blister packaging.

For consumers prioritizing traceable production, domestic finished-product manufacturing, vegan compatibility, comprehensive testing, and freshness protection, Astadaily is the stronger overall choice.

Frequently Asked Questions

Is Astadaily better than Natural Factors Astaxanthin?

Astadaily offers clearer sourcing and manufacturing information, a vegan and Halal-certified formula, comprehensive third-party testing, and individually sealed blister packaging. Natural Factors offers stronger brand recognition, wider retail availability, and both 6 mg and 12 mg dosage options.

Is Natural Factors Astaxanthin made in Canada?

The product packaging states that it is packaged in Canada. This confirms Canadian packaging but does not necessarily mean that the softgels themselves were manufactured in Canada. Consumers seeking clarification should request the country of manufacture directly from the company.

Is Natural Factors Astaxanthin vegan?

No. The softgel contains gelatin, along with glycerin and water, so it is not suitable for a vegan diet.

Where does Natural Factors source its astaxanthin?

Natural Factors identifies its astaxanthin as naturally sourced from microalgae, but does not prominently disclose the original branded ingredient supplier, cultivation method, or extraction technology.

Do both products have Health Canada NPNs?

Yes. Both brands offer Health Canada-licensed natural health products with NPNs. An NPN indicates that the authorized product has been reviewed under Canada’s natural health product framework, but it does not mean that competing products use the same ingredient source or manufacturing process.

Which product offers better value?

Natural Factors may offer strong value for consumers prioritizing retail accessibility, brand familiarity, and a single 12 mg softgel. Astadaily may provide better overall value for those prioritizing transparent sourcing, Canadian manufacturing, vegan and Halal compatibility, extensive testing, and individual freshness protection.
