How to Navigate Nutrex Hawaii's Online Store for Spirulina and BioAstin

Nutrex Hawaii's site is organized around three product families — BioAstin Hawaiian Astaxanthin, Hawaiian Spirulina, and TurmericAstin — with dedicated shop links for each format and strength. If you already know which type you want, the fastest route is to jump straight to the matching shop link below rather than browsing the homepage. If you're still deciding between astaxanthin and spirulina, start with the product-line comparison further down.

Quick Paths to Each Product Category

The homepage exposes these shop entry points directly:

BioAstin is described as the nation's #1 brand of astaxanthin, available in 4MG and 12MG strengths, with vegan options and condition-specific products. Hawaiian Spirulina is described as the nation's #1 brand of spirulina, sold as powder or tablets, including larger bags. TurmericAstin combines BioAstin Hawaiian Astaxanthin with Organic Turmeric Root Extract (95% curcuminoids).

Choosing Between the Main Lines

Use these distinctions to pick a starting category:

• BioAstin Hawaiian Astaxanthin — positioned as a natural antioxidant with stated benefits for joints, skin, heart, and eye health, plus recovery from exercise. Choose this line if you want astaxanthin specifically, and then pick 4MG or 12MG based on the strength you're after, or the vegan version if that matters to you.
• Hawaiian Spirulina — positioned around immune function and cardiovascular benefits. Choose this line if you want spirulina; then decide between tablets (convenient, fixed dose) and powder (flexible for smoothies or recipes), and check whether a larger bag suits your usage.
• TurmericAstin — a single combined product rather than a range. Choose this if you want astaxanthin and turmeric together in one item instead of buying them separately.

A newer addition worth noting: Hawaiian Spirulina Superfood Gummies, enriched with 25mcg (1000 IU) of vitamin D3, for those who prefer a gummy over tablets or powder.

Adding to Cart and Checking Out

Product pages include an "Item added to your cart" confirmation, so you can add items and keep browsing before checkout. The site does not publish pricing or payment details on the pages reviewed here, so confirm cost, shipping, and payment options on the individual product or cart pages before completing an order.

If You Want Context Before Buying

Beyond the shop links, the site carries supporting content for shoppers who want background first:

• Farm information — "It Matters Where It's Grown," explaining that products are grown on the company's farm in Hawaii.
• Ambassadors — including triathlete Dave Scott.
• Recipes — such as an Earth Day smoothie with spirulina.
• Mission — "Whole Health through Hawaiian Microalgae."

These sections don't change what you can buy, but they explain the sourcing claim behind the "grown in Hawaii" positioning if that's part of your decision.
