Formulation Differences

Double Wood offers a slightly higher dose at 1,200 mg versus Atlantic Naturals’ 1,000 mg, and packs 180 capsules per bottle compared to 120. On paper, that’s significantly more product for less money. Double Wood is known as a budget supplement brand across many categories, and their sea moss offering follows that pattern.

Atlantic Naturals counters with USDA Organic certification and transparent North Atlantic sourcing. They use vegetable capsules (vegan-friendly), while Double Wood uses gelatin capsules — an important distinction for plant-based consumers.

Quality Considerations

Both brands conduct third-party testing, which is the baseline for any reputable supplement. The USDA Organic certification on Atlantic Naturals provides an additional layer of quality assurance regarding how the sea moss is harvested and processed.

Double Wood is a well-established supplement company with a good reputation for delivering what’s on the label. Their sea moss is sourced from “Irish Moss” without specific geographic detail, which is less transparent than Atlantic Naturals but not necessarily a red flag.

Our Verdict

This comes down to priorities. Double Wood wins on pure value — more capsules, higher dose, lower price. It’s a solid budget pick for people who want straightforward sea moss supplementation without frills. Atlantic Naturals wins on quality signals — organic certification, transparent sourcing, and vegan capsules. If organic matters to you or you follow a plant-based diet, the modest price premium is easily justified.
