Theoretically, CLA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
 Details
Some clinical evidence suggests that intake of CLA reduces platelet aggregation by approximately 10% (45607). The clinical significance of this effect is unclear.
|
Theoretically, taking CLA with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, taking black seed with ramipril might increase the risk of hypotension.
Details
Some clinical research shows that CLA enhances the blood pressure-lowering effects of ramipril (45569).
|
Theoretically, L-carnitine might increase the anticoagulant effects of acenocoumarol.
Details
L-carnitine might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting (9878,12165). There are at least two case reports of INR elevation with concomitant use. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product (12165).

Below is general information about the adverse effects of the known ingredients contained in the product CLK. 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, 7-keto-DHEA seems to be well tolerated when used short-term. Only mild side effects such as nausea, vertigo, and decreased blood pressure have been reported (10404,92185).
Cardiovascular ...Orally, 7-keto-DHEA may modestly decrease blood pressure in some patients (10404).
Gastrointestinal ...Orally, 7-keto-DHEA has been associated with two reports of nausea in one clinical study (92185).
Hematologic ...A case report describes decreased hemoglobin and hematocrit levels in a man taking 7-keto-DHEA orally, 25 mg twice daily for 7 days (10404). The clinical significance of this is not clear.
Neurologic/CNS ...Orally, 7-keto-DHEA has been associated with one report of vertigo in one clinical study (92185).
General
...Orally, CLA is well tolerated when found in foods.
When taken in medicinal amounts, CLA seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, dyspepsia, flatulence, loose stools, and nausea.
Serious Adverse Effects (Rare) :
Orally: Cases of hepatotoxicity have been reported.
Cardiovascular
...Some preliminary clinical research suggests that the t10,c12 isomer of CLA can decrease high-density lipoprotein (HDL) cholesterol levels (2821).
This isomer of CLA, as well as a mixture of CLA isomers, seems to increase plasma triglyceride levels, the ratio of low-density lipoprotein (LDL) cholesterol to HDL cholesterol, and the ratio of total cholesterol to HDL cholesterol (45148,45468), although not all research has identified these effects (107475).
A meta-analysis of 6 randomized, controlled trials shows that administration of CLA in individuals who are overweight or obese significantly increases lipoprotein (a) levels, a value associated with increased risk of cardiovascular disease. Subgroup analyses suggest this increase is more prominent in trials that are longer than 6 months in duration and with CLA doses of at least 3.5 grams daily (107475).
Endocrine ...Orally, CLA has been shown to increase insulin resistance and glucose concentrations, as well as decrease insulin sensitivity in some patients, including obese individuals or patients with type 2 diabetes (2821,13026,45145,45152,45513). Some evidence suggests that this effect is isomer-specific and occurs with only the t10,c12 isomer (2821,13026), while other evidence shows that decreased insulin sensitivity may also occur with the c9,t11 isomer or with a 50:50 mixture of c9,t11 and t10,c12 isomers (45145,45152).
Gastrointestinal ...Orally, the most common adverse effect reported with CLA is gastrointestinal upset including diarrhea, constipation, nausea, loose stools, dyspepsia, bloating, and flatulence (3153,4947,45280,45705,45730,111056). Esophageal irritation was reported in one patient who bit open and swallowed a capsule containing CLA (45577).
Hepatic ...Orally, clinical research shows that CLA 3 grams daily for 12 weeks does not affect liver outcome measures (105809). However, there are at least two case reports of hepatotoxicity. Asthenia, jaundice, and pruritus were reported in a 46-year-old female who consumed CLA for two weeks. Abnormal liver enzyme levels returned to normal following discontinuation of CLA supplementation (45483). Hepatotoxicity, presenting as fulminant hepatitis and characterized by anorexia, nausea, jaundice, choluria, and hepatic encephalopathy requiring liver transplantation has also been reported in a 63-year-old female taking a CLA-containing weight-loss supplement for one month (91589).
Musculoskeletal ...Orally, CLA has been reported to cause back ache in one individual in one clinical trial (45787).
Neurologic/CNS ...Orally, CLA may cause headache or fatigue (3153,45787). In one case report, a 50-year-old female presented with headache and subarachnoid hemorrhage due to reversible cerebral vasoconstriction syndrome (RCVS) after taking a combination product containing green tea, L-carnitine, and CLA for one week. At 28 days after discontinuation of the combination product and surgery, angiography showed complete regression of vascular restrictions (97007). It is unclear if this adverse effect was due to CLA, another ingredient in the product, or a combination of ingredients.
Other ...Orally, CLA has been reported to cause halitosis in one patient in one clinical trial (45839).
General
...Orally and intravenously, L-carnitine is generally well tolerated.
Most Common Adverse Effects:
All routes of administration: Abdominal cramps, abdominal pain, diarrhea, gastritis, heartburn, nausea, reduced appetite, and vomiting. A fish-like body odor has also been reported.
Serious Adverse Effects (Rare):
All routes of administration: Seizures.
Cardiovascular ...According to population research, plasma L-carnitine levels are associated with increased risk of cardiovascular disease and major cardiac events (90635). However, oral supplementation with L-carnitine does not appear to be associated with an increased risk of cardiovascular disease. In fact, a meta-analysis of clinical research shows that L-carnitine supplementation is associated with a reduction in all-cause mortality, as well as ventricular arrhythmias and the development of angina and does not increase the development of heart failure or myocardial reinfarction (59037). Also, another meta-analysis suggests that L-carnitine does not affect mortality or cardiovascular outcomes in patients with a previous myocardial infarction (90630).
Dermatologic ...Orally, L-carnitine has been reported to cause skin rash in a small number of cases (16105,91724). Two patients in a hair growth study using topical carnitine reported mild itching and increased dandruff, while a third reported strong itching with reddish bumps and a burning sensation (58390). When a specific formulation containing L-carnitine, licochalcone, and 1,2-decanediol was applied to the face, mild skin dryness and tightness was reported by 12% of volunteers, compared with 4% to 8% of those in the vehicle-only control group (26493).
Gastrointestinal ...Orally and intravenously, L-carnitine has been associated with nausea, epigastric discomfort, vomiting, abdominal cramps, heartburn, gastritis, anorexia, and diarrhea (3616,3624,59030,95069,95070,101562,107410,111870,111887,111891). Orally, diarrhea or colitis symptoms (1433,3630,16105,16107,16111,23437,58523,58554,59020,90623), nausea and abdominal pain (16105,16106,26499,58169,58392,58554,90623,90634), indigestion (26703), and constipation (58523) have been reported in various clinical trials.
Hematologic ...In one case report, L-carnitine 990 mg twice daily was started in a female presenting to hospital with valproic acid toxicity. Blood phosphorous levels subsequently fell from 2.3 mg/dL to 1.3 mg/dL over 4 days. After discontinuation of L-carnitine, blood phosphorus levels increased to 1.8 mg/dL. The authors suggested that the role of L-carnitine in improved protein metabolism may play a role in the declining levels of phosphorous in the blood and increased risk of hypophosphatemia (90628).
Neurologic/CNS ...Orally or intravenously, L-carnitine has been associated with seizures (3616). Orally, use of L-carnitine in clinical trials has resulted in headache, although this event is rare (58554,95070,111891). L-carnitine may also cause agitation (95070).
Other ...Orally or intravenously, L-carnitine has been associated with a fish-like body odor (1433,3616,58166,59854,90623). One of its metabolites, trimethylamine N-oxide, can cause the urine, breath, and sweat to have a fishy odor (12756,58664).
