Our Full Review
This formula combines Atlantic Naturals’ wildcrafted Irish sea moss with organic spirulina, creating a nutrient-dense supplement particularly beneficial for iron and energy support.
Spirulina contains 60-70 percent complete protein by weight, all essential amino acids, and is one of the richest plant sources of iron and B-vitamins. Combined with sea moss’s mineral wealth, you get remarkably broad nutritional coverage.
The iron content makes this formula especially valuable for vegetarians, vegans, and women. Spirulina’s iron is highly bioavailable, and the vitamin C naturally present in sea moss enhances iron absorption even further.
Spirulina also contains phycocyanin, a pigment with potent antioxidant and anti-inflammatory properties linked to improved blood sugar regulation and reduced oxidative stress. Atlantic Naturals maintains their standard quality: USDA Organic, vegan capsules, third-party tested, zero fillers.
Each bottle provides 120 capsules for a 60-day supply at approximately $26. Those with autoimmune conditions should consult their healthcare provider before supplementing with spirulina.
