Below is general information about the safety of the known ingredients contained in the product Rainbow Ocean Nectar Marine Phytoplankton. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally, short-term. Ascophyllum nodosum dried powder has been used with apparent safety at a dose of up to 500 mg daily for up to 6 months (94996,94997,103900). However, marine products such as Ascophyllum nodosum are known to accumulate heavy metals such as arsenic (94997,94999). Some supplement products are prospectively analyzed to confirm a lack of contaminants and that heavy metal levels are below threshold (94997).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using amounts greater than those found in food.
LIKELY SAFE ...when used in amounts found in foods. Astaxanthin has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when taken orally and appropriately. Astaxanthin 4-18 mg daily has been used with apparent safety for up to 12 weeks. Doses of 40 mg daily have been used with apparent safety for up to 4 weeks (19165,19167,19197,32621,96884,105100).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using in amounts greater than those typically found in foods.
POSSIBLY SAFE ...when non-contaminated species of spirulina blue-green algae are used orally and appropriately (91713). The blue-green algae species Arthrospira platensis has been used with apparent safety in doses up to 19 grams daily for 2 months, or 10 grams daily for 6 months (18296,18300,18306,75944,91705,99703,104567,109965). The blue-green algae species Arthrospira fusiformis has been used with apparent safety in doses up to 4 grams daily for 3 months, or 1 gram daily for 12 months (15782,91717). Another blue-green algae species, Arthrospira maxima, has been used with apparent safety in a dose of 4.5 grams daily for up to 12 weeks (18297,99654,99655,102688). ...when non-contaminated, non-toxin producing strains of blue-green algae from the Aphanizomenon flos-aquae species are used orally and appropriately. Doses up to 1.6 grams daily have been used with apparent safety for up to 6 months (14842,18310). Some blue-green algae species can produce toxins called microcystins. According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549).
POSSIBLY UNSAFE ...when contaminated blue-green algae are used orally. Blue-green algae can be contaminated with heavy metals (including mercury, cadmium, lead, or arsenic), neurotoxins, and toxic microcystin-producing cyanobacteria such as Microcystis aeruginosa (9171,75966,91704,91711,96550). Microcystins are most commonly reported in the blue-green algae species Aphanizomenon flos-aquae harvested from Upper Klamath Lake in Oregon. The Oregon Department of Health has set a limit of 1 mcg of microcystin-LR equivalents per gram dry weight of blue-green algae, assuming consumption of about 2 grams/day by adults (91704,91713). However, many samples of Aphanizomenon flos-aquae have been reported to contain higher levels than this (9171,91704). According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549). When consumed orally, microcystins accumulate in the liver, binding to and inhibiting protein phosphatases, causing hepatocyte damage and possible tumor promotion (9171). Aphanizomenon flos-aquae can also produce neurotoxic compounds that may be present in supplements containing this organism (91704).
CHILDREN: POSSIBLY UNSAFE
when blue-green algae products are used orally.
Blue-green algae can accumulate heavy metals such as lead and mercury (91704,91711). They can also contain toxic microcystins produced by contaminating species of cyanobacteria such a Microcystis aeruginosa (91704). Children are more sensitive to poisoning by microcystins (3536). The Oregon Department of Health has set a limit for microcystins of 1 mcg per gram dry weight of blue-green algae, but some countries have set very low exposure limits of 0.2 mcg per day and 0.8 mcg per day for infants and children, respectively (91704).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Some blue-green algae products, specifically those of the species Aphanizomenon flos-aquae, have been found to contain low amounts of beta-methylamino-L-alanine (BMAA). BMAA is associated with neurodegenerative diseases, and breast milk has been shown to be a potential source of BMAA exposure in infants (96550).
LIKELY SAFE ...when used orally and appropriately, short-term. Tablets and liquids containing chlorella 3-10 grams or 60-100 mL daily have been safely used in clinical studies lasting 2-3 months (5890,92130,92131). Also, chlorella extract 200-1800 mg daily has been safely used in clinical research for 4-6 weeks (10388,92132). There is insufficient reliable information available about the safety of chlorella when used topically.
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately in medicinal amounts for up to approximately 28 weeks.
A commercially available chlorella supplement (Sun Chlorella A, Sun Chlorella Corp.) has been safely used in doses of 6 grams daily, starting during the 12-18th week of gestation and continuing until delivery (95013).
LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when a specific Ecklonia cava phlorotannin extract (SeaPolynol) is used orally and appropriately. Doses of up to 400 mg daily have been used with apparent safety for 12 weeks (106334,106336). According to the European Food Safety Authority (EFSA), doses of up to 263 mg daily are considered safe based on extrapolation from animal toxicity research (106333). ...when other sources of Ecklonia cava polyphenols are used orally, short-term. Doses up to 144 mg daily have been used with apparent safety for up to 12 weeks (96376). ...when a specific Ecklonia cava polyphenol-rich extract (AG-dieckol, Aqua Green Tech Co.) is used orally and appropriately. Doses of up to 1500 mg daily have been used with apparent safety for up to 12 weeks (96375).
CHILDREN: POSSIBLY SAFE
when a specific Ecklonia cava phlorotannin extract (SeaPolynol) is used orally and appropriately in children 12 years and older.
According to the EFSA, doses of up to 163 mg daily are considered safe in children aged 12-14 years, and 230 mg daily is considered safe in children aged 14 years and above, based on extrapolation from animal toxicity research (106333). There is insufficient reliable information available about the safety of Ecklonia cava in children under 12 years of age.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used in amounts found in foods. Laminaria has Generally Recognized as Safe (GRAS) status in the US (94048).
POSSIBLY SAFE ...when iodine-reduced laminaria supplements are used, short-term. Iodine-reduced laminaria powder has been safely used at doses up to 6 grams daily for up to 8 weeks (109572).
POSSIBLY UNSAFE ...when used orally in medicinal amounts. The average laminaria-based supplement might contain as much as 1000 mcg of iodine. Ingesting more than 1100 mcg iodine daily (the tolerable upper intake level) can cause hypothyroidism, hyperthyroidism, or exacerbate existing hyperthyroidism (9556,94046). In addition, some laminaria supplements may contain arsenic (645,10275,15588). There is insufficient reliable information available about the safety of laminaria for its other uses.
PREGNANCY: POSSIBLY UNSAFE
when used intravaginally for cervical ripening; there is an increased risk of parental and neonatal infection (8945).
PREGNANCY: LIKELY UNSAFE
when used intravaginally to induce labor; use has been associated with endometriosis, neonatal sepsis, fetal hypoxia, and intrauterine death (6).
PREGNANCY: UNSAFE
when used orally due to potential hormonal effects (19); avoid using.
LACTATION: LIKELY UNSAFE
when used orally because of potential toxicity (19).
Below is general information about the interactions of the known ingredients contained in the product Rainbow Ocean Nectar Marine Phytoplankton. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, combining Ascophyllum nodosum with amiodarone might cause excessively high iodine levels.
Details
Ascophyllum nodosum contains iodine (94997,95000,95102), although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide (94997). Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function (7135,17574). Monitor thyroid function.
|
Due to its iodine content, Ascophyllum nodosum might alter the effects of antithyroid drugs.
Details
Ascophyllum nodosum contains iodine (94997,95000,95102), although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide (94997). Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Ascophyllum nodosum while using antithyroid drugs could alter the effects of the antithyroid drugs (17574).
|
Due to its iodine content, Ascophyllum nodosum might alter the effects of thyroid hormone.

Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Ascophyllum nodosum while using thyroid hormone could alter the effects of thyroid hormone (17574).
|
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP2B6.
Details
In vitro research shows that astaxanthin induces cytochrome CYP2B6 enzyme activity in human hepatocytes (32613). This effect has not been reported in humans.
|
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
Details
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes (32613). This effect has not been reported in humans.
|
Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Details
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro (18311,18312,75892,92162,92163). However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time (97202).
|
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs (18299). However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes (102689,109970). A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects (109970).
|
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Details
|
Theoretically, chlorella might have additive effects with photosensitizing drugs.
Details
Chlorella has been reported to cause photosensitization (3900,5852). In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body (5852). Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.
|
Theoretically, chlorella might reduce the clinical effects of warfarin.
Details
|
Theoretically, laminaria might increase the risk of hyperkalemia when taken with ACEIs.
Details
Laminaria contains potassium (19).
|
Theoretically, combining laminaria with amiodarone might cause excessively high iodine levels.
Details
|
Due to its iodine content, laminaria might alter the effects of antithyroid drugs.
Details
|
Theoretically, laminaria might increase the risk of hyperkalemia, which could increase the effects and adverse effects of digoxin.
Details
Laminaria contains potassium (19).
|
Theoretically, laminaria might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Details

Below is general information about the adverse effects of the known ingredients contained in the product Rainbow Ocean Nectar Marine Phytoplankton. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General ...Orally, Ascophyllum nodosum seems to be generally well-tolerated.
Endocrine ...Orally, taking Ascophyllum nodosum powder 500 mg daily for 14 days has been reported to cause elevated levels of thyroid stimulating hormone (TSH) in 2 of 22 women in a clinical trial. The powder contained 356 mcg iodine per 500 mg. Levels of free thyroxine (T4) were unaffected (94997).
Gastrointestinal ...Orally, Ascophyllum nodosum has been reported to cause stomach discomfort in one clinical trial (94996).
General
...Orally, astaxanthin seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, red fecal color.
Gastrointestinal ...Orally, astaxanthin 6 mg daily has caused two cases of increased bowel movements and two cases of red fecal color (91736). A higher dose of astaxanthin (AstaCarox, AstaReal AB) 40 mg daily has caused severe stomach/abdominal pain in two patients (19165).
Ocular/Otic ...Canthaxanthin, another carotenoid substance that is chemically related to astaxanthin, has caused crystals in the retina and loss of visual acuity in one patient (8455). This effect has not been observed with astaxanthin, but patients who have visual changes while taking astaxanthin should stop taking it immediately.
General
...Orally, spirulina blue-green algae seem to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal cramps, bloating, diarrhea, dizziness, fatigue, flatulence, headache, nausea, and vomiting.
Dermatologic ...Orally, a severe rash has been reported in a 49-year-old woman after taking a spirulina blue-green algae supplement (species and dose unknown). After stopping the supplement, inflammatory myopathy with muscle weakness and elevated creatine kinase occurred. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). In another case report, an 82 year-old woman developed a blistering skin condition over a 2-year period while taking spirulina blue-green algae (A. platensis, dose unknown). She had partly hemorrhagic bullae, secreting erosions and macerations. These symptoms resolved when the supplement was stopped and the patient was treated with oral prednisone, topical silver sulfadiazine, and topical triamcinolone / neomycin (75921).
Gastrointestinal ...Orally, gastrointestinal complaints are amongst the most common adverse effects associated with spirulina blue-green algae, including nausea, vomiting, diarrhea, and abdominal cramps (19272,75924,91713,109969). Similarly, common adverse effects associated with the blue-green algae species Aphanizomenon flos-aquae are stomach upset, flatulence, diarrhea, and bloating (14842).
Hematologic ...Orally, three cases of mild gum bleeding and one case of mild bruising have been reported in patients taking spirulina blue-green algae (Cyactiv, Cerule LLC) 2. 3 grams daily (containing approximately 1 gram of phycocanin) for 2 weeks (97202).
Hepatic ...Orally, significant elevations of liver function tests within 2 weeks of starting a spirulina blue-green algae supplement (species and dose unknown) have been reported in a 52-year-old man stabilized on amlodipine, simvastatin, and acarbose. A biopsy showed feathery degeneration and ballooning of hepatic cells. Cholestasis was present, and an ex-vivo lymphocyte stimulation test for spirulina blue-green algae was positive. All drugs and the spirulina blue-green algae supplement were stopped, with return of the LFTs to normal (9172).
Immunologic
...Orally, urticarial rashes and pruritus have occurred as part of generalized allergic reactions to blue-green algae (91706,91711,91712).
In one case report, a 14-year-old male experienced anaphylaxis with urticaria, lip edema, and asthma 6 hours after taking five tablets of spirulina blue-green algae (A. platensis, strength unknown). He had a positive skin prick test. Oral challenge to an extract of the tablets, and IgE from his serum, reacted with the beta chain of C-phycocyanin from A. platensis (91712).
In another case report, a 17-year-old male with a history of multiple allergies developed rash, pruritus, angioedema, wheezing, and dyspnea within 10 minutes of taking spirulina blue-green algae (A. platensis) 300 mg. He had a positive skin test to A. platensis but no other ingredients of the tablets (91706).
Musculoskeletal ...Orally, after a 49-year-old woman stopped taking a spirulina blue-green algae supplement (species and dose unknown), the patient experienced inflammatory myopathy with muscle weakness and elevated creatine kinase. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). Another case report describes acute rhabdomyolysis that occurred after consumption of spirulina (Arthrospira platensis, Hawaiian spirulina, Solgar Inc., Leonia, NJ) 3 grams daily for 1 month. The 24-year old man presented with weakness, myalgias, elevated creatine kinase and liver function tests, and myoglobinuria (75922).
General
...Orally, chlorella is generally well-tolerated.
Most Common Adverse Effects:
Orally: Allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, flatus, nausea, photosensitivity, and stool discoloration.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Dermatologic ...Orally, photosensitivity reactions have occurred following ingestion of chlorella (3900,5852). According to case reports, five patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body (5852). The photosensitizing agent in the chlorella tablets was identified as pheophorbide-a and its ester.
Gastrointestinal
...Orally, chlorella can cause diarrhea, abdominal cramping, flatus, and nausea, especially during the first two weeks of treatment (5890,6804,92130,92132).
In one clinical trial, one out of 42 patients reported nausea and one reported diarrhea (92132). In another trial, taking chlorella tablets (Sun Chlorella A, Sun Chlorella Corp) and a chlorella extract (Wakasa Gold, Sun Chlorella Corp) resulted in transient worsening of constipation in 4 of 13 patients and transient mild diarrhea in 2 of 13 patients (92130).
Green discoloration of the feces has also been reported, due to the chlorophyll content of chlorella (6804,95013).
Hematologic ...Orally, chlorella has been linked to one case of thrombocytopenia; however, causality has not been determined. A 49-year-old female living in Turkey presented with thrombocytopenia (a platelet count of 27,000/mm3) after taking chlorella 1080 mg daily for 20 days. Platelet counts had been normal one month earlier, and returned to normal two weeks after discontinuing the chlorella supplement (99879).
Immunologic ...Allergic reactions, including asthma and anaphylaxis, have been reported in people taking chlorella and in those preparing chlorella tablets (3900,5847,41827,105645).
Neurologic/CNS
...Orally, manganese (Mn)-induced parkinsonism has been reported after long-term consumption of chlorella extract.
In this case, a patient on maintenance hemodialysis reported gait disturbance, dysarthria, elevated serum and cerebrospinal fluid manganese levels, and abnormal magnetic resonance imaging (MRI) findings of the brain. The authors identified the condition as a rare case of Mn-induced parkinsonism, which may have been due to long-term ingestion of a chlorella extract containing 1.7 mg of Mn in the usual daily dose. The patient underwent edetic acid infusion therapy, which improved the MRI abnormalities and the other symptoms improved four months later (41817).
In one study, fatigue was reported in 18 of 41 patients receiving chlorella 200 mg (10388).
General ...Orally, Ecklonia cava extract and Ecklonia cava polyphenols seem to be well tolerated.
Dermatologic ...Orally, alopecia has been reported by one person in a clinical trial (106335).
Gastrointestinal ...Orally, nausea, dyspepsia, and diarrhea have been reported by one person each in a clinical trial (106335).
General
...Orally, iodine-reduced laminaria seems to be well tolerated, while other laminaria formulations may contain excess amounts of iodine, as well as arsenic.
Most Common Adverse Effects:
Intravaginally: Cervical bleeding and pelvic cramps.
Serious Adverse Effects (Rare):
Orally: Arsenic poisoning.
Intravaginally: Rupture of cervical wall, fetal hypoxia, and fetal death. Anaphylaxis in sensitive individuals.
Dermatologic ...Orally, laminaria has been linked to a report of induced or exacerbated acne (9555).
Endocrine ...Orally, laminaria can affect levels of certain thyroid hormones, and might cause hypothyroidism or hyperthyroidism, or exacerbate existing hyperthyroidism (9556,94046).
Genitourinary ...Intravaginally, laminaria used for cervical ripening can cause pelvic cramps and cervical bleeding (8945). Uterine contractions associated with laminaria use have been implicated in fetal hypoxia and subsequent intrauterine death (6). Use of endocervical laminaria tents has been associated with possible rupture of the cervical wall and subsequent neonatal and parental infection (6,8945).
Immunologic ...There are case reports of anaphylactic reactions to laminaria when used intravaginally as a cervical dilator. In at least one case, ventilation was required (102766).
Other ...Laminaria concentrates arsenic from the ocean. In one case, use of an oral laminaria supplement for several months resulted in symptoms of arsenic poisoning including headache, weakness, fatigue, worsening memory loss, rash, nail damage, diarrhea, and vomiting. Urinary arsenic levels were elevated (15588). The concentration of arsenic in laminaria may vary between different batches, and also depends upon the part of the world where it was harvested (645,10275,15588). The concentration of arsenic has been reported to be higher in preparations from Australia than from Great Britain (645,10275).
