No consumer class action against AlgaeCal Inc. has been publicly documented, and the AlgaeCal lawsuit history on record consists of two trademark cases the company itself filed against competitors and critics.1Judicial Ocean. AlgaeCal Lawsuit The regulatory scrutiny that most closely touches AlgaeCal’s product involved a separate company, Garden of Life, which used AlgaeCal-derived calcium. Independent lab testing and academic criticism of the company’s bone density claims sit alongside that record but have not produced litigation against AlgaeCal.
Trademark Cases AlgaeCal Has Filed
AlgaeCal v. Finlayson (2013)
In July 2013, AlgaeCal filed a trademark infringement suit in the U.S. District Court for the Western District of Texas against James Finlayson, Thomas Wahl, and entities operating the domains AlgaeCalFraud.com and BoneBlast.com. The case, AlgaeCal, Inc. v. Finlayson et al. (1:13-cv-00642), was assigned to Judge Sam Sparks and terminated in November 2013.2PACER Monitor. AlgaeCal, Inc. v. Finlayson et al
AlgaeCal v. OceanEssence Nutrition (2025)
On January 13, 2025, AlgaeCal filed a complaint against OceanEssence Nutrition Inc. in the U.S. District Court for the Northern District of Illinois before Judge Sara Lee Ellis. The case (1:25-cv-00346) raises claims tied to trademark use, keyword advertising, and competitive marketing practices.3CourtListener. AlgaeCal Inc. v. OceanEssence Nutrition Inc. OceanEssence sells competing algae-based calcium products under the myOceanEssence brand, including a “Total Bone Support” formula built around the Aquamin algae-derived mineral complex.4myOceanEssence. OceanEssence Nutrition Homepage OceanEssence filed a counterclaim in March 2025 and moved to dismiss the complaint in April 2025 for failure to state a claim. The court ruled on that motion in May 2025 and on a motion to strike in January 2026, and the case remains active in discovery.
FTC Action Involving AlgaeCal-Derived Calcium
The most significant regulatory action touching AlgaeCal’s ingredient did not name AlgaeCal as a party. It involved Garden of Life, Inc., which used AlgaeCal-derived calcium in several products.
In 2006, the FTC charged Garden of Life and founder Jordan Rubin with unsubstantiated claims that certain supplements could treat cancer, immune disorders, and Crohn’s disease. The parties settled through a Stipulated Final Order in U.S. District Court in Miami. Garden of Life and Rubin agreed to pay $225,000 in consumer redress, plus a contingent judgment of roughly $47.6 million that would come due if the defendants were found to have misrepresented their finances.5Sun Sentinel.

Garden of Life Stipulated Final Order and Judgment
In 2011, the FTC moved to hold Garden of Life in civil contempt over a 2009 product line that included RAW Calcium and the Grow Bone System, both using algae-derived calcium from AlgaeCal’s ingredient. The FTC alleged the company had claimed its “plant-form” calcium was superior to “rock-source” calcium and could reverse bone density loss where competitors could only slow it, and that it had misrepresented study results showing a 2.8% to 3.7% increase in bone mineral density.7Federal Trade Commission. FTC Appellate Brief, Garden of Life
On February 27, 2012, the U.S. District Court for the Southern District of Florida denied the contempt motion, holding that the FTC had not shown violations by clear and convincing evidence. The court read the 2006 order narrowly, finding that its ban on comparative health benefit claims did not reach the general superiority marketing at issue. The FTC appealed to the Eleventh Circuit.7Federal Trade Commission. FTC Appellate Brief, Garden of Life AlgaeCal Inc. was not a party at any stage.
Lead Content Findings by ConsumerLab
Independent testing lab ConsumerLab has flagged AlgaeCal for lead content on at least two occasions. In 2015, it found approximately 5 micrograms of lead per daily serving. A 2017 follow-up test found lower levels, between 1 and 2 micrograms per daily serving. ConsumerLab applies California’s threshold of 0.5 micrograms per daily serving, with some leeway noted for mineral-based supplements that inherently contain trace contaminants.8MelioGuide. Calcium Supplements for Osteoporosis
AlgaeCal has disputed ConsumerLab’s characterization, calling the reports a “myth” and “balderdash.” The company acknowledged that 1.4 micrograms of naturally occurring lead are present in a four-capsule daily serving and said this falls within what the FDA considers safe. It also acknowledged a “human error” in reporting the lead quantity in 2015.9AlgaeCal Blog. Ditch the Toxins No regulatory action or lawsuit has resulted from the ConsumerLab findings.
Scientific Criticism of the Bone Density Claim
AlgaeCal markets its products as the only calcium supplement clinically shown to increase bone density, backed by a small number of industry-funded studies.10AlgaeCal. About AlgaeCal A 2011 comparative effectiveness study in the Nutrition Journal enrolled 216 adults and reported a mean annualized bone mineral density increase of 2.18% in participants taking one AlgaeCal formulation. The study was funded by “a small nutritional company with a limited budget” and was open-label without a placebo control, though an independent statistician served as principal investigator.11ResearchGate. Changes in Total Body Bone Mineral Density Following a Common Bone Health Plan A related 2011 study in the International Journal of Medical Sciences tested 176 women, was corrected in 2013, and lacked a simultaneous placebo arm because of budget constraints.12PubMed Central. Comparative Effectiveness Study of Bone Density Changes A 2016 study in the Journal of the American College of Nutrition reported that some users saw an increase in bone density and that the product was not associated with adverse effects.13UCLA Health. Calcium Supplement AlgaeCal Can Increase Bone Density
A McGill University analysis found that the company-funded studies were not placebo-controlled and offered no demonstration that AlgaeCal outperforms cheaper calcium and vitamin D supplements. The analysis added that increased bone density does not necessarily translate into fewer fractures, which is the outcome that matters clinically.14McGill University Office for Science and Society. Health Canada and Natural Health Products A separate review pointed to a 24-month study of postmenopausal women using the related algae-calcium ingredient Aquamin, which found no significant improvement in bone mineral density compared with placebo. That review cautioned that algae-derived calcium still carries the standard supplemental calcium risks, including a 17% increased risk of kidney stones observed in the Women’s Health Initiative and a possible link to cardiovascular events, and it recommended resistance training, adequate protein, and FDA-approved medications for osteoporosis patients.15Ajenda Health.

AlgaeCal offers a bone density guarantee, promising a full refund if a customer’s follow-up DEXA scan does not show increased bone density after at least six months of use.16AlgaeCal.
