Astaxanthin is one of the most powerful carotenoid antioxidants, but its chemistry creates a practical problem: the pure molecule is oil-soluble, unstable in water and strongly red. The water-soluble 10% CWD beadlet grade solves all three issues at once, which is why it has become the default choice for beverages, gummies and instant powders. This guide explains how the beadlets work, how to dose them and what to verify. Core Nutrix supplies water-soluble astaxanthin 10% CWD beadlets (CAS 472-61-7), a deep-red beadlet or powder packed in 25 kg drums.
Why Standard Astaxanthin Does Not Mix
- Lipophilic molecule: astaxanthin dissolves in oil, not water, so standard powder floats, streaks and settles in aqueous matrices.
- Stability risk: exposed astaxanthin oxidizes under light, heat and oxygen, fading from red to orange and losing activity.
- Intense color: even 4 mg of pure astaxanthin turns a liter of water noticeably red, which limits dosing flexibility.
What CWD Beadlets Change
- Encapsulation: astaxanthin is dissolved in a carrier oil and embedded in a protective matrix, then spray-dried into uniform beadlets that disperse in cold water.
- 10% loading: each gram of beadlets delivers 100 mg of astaxanthin, so a 4 mg serving needs only 40 mg of material – easy to weigh and blend.
- Protection: the matrix shields the carotenoid from oxygen and light, keeping the red color and assay stable through processing and shelf life.
- Dispersibility: the beadlets form a stable suspension in drinks rather than an oil ring or sediment layer.
Dose and Format Guidance
- Serving sizes: supplements typically deliver 4-12 mg astaxanthin per serving; beauty and eye products lean 4-6 mg, sports and recovery 8-12 mg.
- Beverages and shots: the beadlets disperse in cold water; test the finished color, because the red tint is part of the product story for many brands.
- Gummies: the grade blends cleanly into gummy bases, with the beadlet matrix surviving moderate heat better than free astaxanthin.
- Instant powders and sachets: the beadlets mix uniformly and stay suspended long enough for consumption.
Quality Checks for the 10% Grade
- Assay: astaxanthin content by HPLC, typically stated on the beadlet basis; confirm whether 10% means free astaxanthin or total carotenoids.
- Beadlet quality: particle size distribution and dispersibility in cold water should be on the specification sheet.
- Color stability: the deep red color should remain stable in sealed, cool, dark storage; shelf life is 24 months.
- Contaminants: heavy metals and microbiology per batch, with third-party verification available on request.
Astaxanthin Sources: Algae vs Synthetic
- Haematococcus pluvialis: this freshwater microalgae is the natural source – under stress the algae produce astaxanthin as protection, and the oleoresin is concentrated before further processing.
- Synthetic astaxanthin: petrochemical-derived material used in feed applications, not suited to natural supplement positioning.
- Natural claim: for supplements, Haematococcus-derived astaxanthin (CAS 472-61-7) is the standard; ask for source documentation with the COA.
How CWD Beadlets Are Made
The beadlet process converts the oil-soluble active into a water-dispersible powder in three steps: the astaxanthin oleoresin is emulsified into microscopic oil droplets, the droplets are stabilized with a protective coating – often starch, protein or gum-based – and the emulsion is spray-dried into uniform beadlets. The result is a free-flowing red powder where each particle carries its own protective shell.
- 10% loading: assayed astaxanthin on the beadlet basis, verified by HPLC.
- Particle control: beadlet size is specified for uniform blending and suspension.
- Protection: the coating shields the carotenoid from oxygen and light, which is why the grade survives beverage processing better than free astaxanthin.
Frequently Asked Questions (FAQ)
Why not use pure astaxanthin powder?
Pure astaxanthin is oil-soluble, unstable in water and intensely colored. The CWD beadlet grade solves solubility, stability and dosing precision in one material.
What does 10% loading mean?
Each gram of beadlets contains 100 mg of astaxanthin. A 4 mg serving is therefore 40 mg of material, which blends accurately even in small sachets.
Will it turn my drink red?
Yes – astaxanthin is naturally red, and the beadlets keep the color uniform rather than streaky. Many brands lean into the red tint as a visual cue; test your target shade at lab scale first.
Can the beadlets survive gummy production?
The matrix is designed for moderate heat and typical gummy pH ranges. We recommend a small pilot batch to confirm color and assay in your specific process.
What documentation ships with each batch?
COA and MSDS with the HPLC assay, beadlet specifications and contaminant panel. Third-party testing is available on request.
What is the MOQ?
Samples start at 0.5-1 kg depending on the item, and bulk ships in 25 kg drums (premium items from 5-10 kg). Contact us for a quote and a free sample.
Is the astaxanthin natural?
Yes – supplement-grade material is derived from Haematococcus pluvialis algae. Source documentation is supplied with the COA.
How do I hit a 4 mg serving accurately?
With the 10% grade, 40 mg of beadlets delivers 4 mg of astaxanthin. The loading makes small servings weighable on standard production scales.
Does the red color fade in drinks?
The beadlet matrix slows oxidation, but finished drinks should still be tested for color and assay over shelf life, and light-protective packaging is recommended.
What documentation ships with each batch?
COA and MSDS with the HPLC assay, beadlet particle data and contaminant panel. Third-party testing is available on request.
What is the MOQ?
Samples start at 0.5-1 kg depending on the item, and bulk ships in 25 kg drums (premium items from 5-10 kg). Contact us for a quote and a free sample.
What is the shelf life of the beadlets?
Twenty-four months sealed in a cool, dark, dry place. Light-protective finished packaging extends color and assay stability further.
Can astaxanthin beadlets be used in tablets?
The beadlets compress acceptably in many tablet blends; a pilot batch confirms beadlet integrity and color distribution in your process.
Can I get a custom astaxanthin loading?
Loadings other than 10% can be discussed for large programs. Standard supply is the 10% CWD grade in 25 kg drums.
Does the grade work in clear beverages?
The beadlets disperse into a suspension rather than a clear solution, so clear drinks show the red tint. Shots, smoothies and cloudy drinks are the natural formats.
What is the MOQ?
Samples start at 0.5-1 kg depending on the item, and bulk ships in 25 kg drums (premium items from 5-10 kg). Contact us for a quote and a free sample.
