Below is general information about the interactions of the known ingredients contained in the product Nutrilite Glucosamine HCl with Boswellia. 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, the antioxidant effects of acerola might reduce the effectiveness of alkylating agents.
 Details
Acerola contains vitamin C, an antioxidant. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as alkylating agents (391). In contrast, other researchers theorize that antioxidants might make alkylating chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.
|
Theoretically, concomitant use of acerola with aluminum salts might increase the amount of aluminum absorbed.
Details
Acerola contains vitamin C. It is thought that vitamin C chelates aluminum, keeping it in solution and available for absorption (10549,10550,10551). In people with normal renal function, urinary excretion of aluminum likely increases, making aluminum retention and toxicity unlikely (10549). However, patients with renal failure who take aluminum-containing compounds, such as phosphate binders, should avoid acerola in doses that provide more vitamin C than the recommended dietary allowances.

Theoretically, the antioxidant effects of acerola might reduce the effectiveness of antitumor antibiotics.

Theoretically, acerola might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Acerola contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels (3046). However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion (10588,10589). The vitamin C content of acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and aspirin is unlikely.
|
Theoretically, concomitant use of acerola with estrogens might increase estrogenic effects.
Details
Acerola contains vitamin C. Increases in plasma estrogen levels of up to 55% have occurred under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products (129,130,11161). It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall (129,11161). When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements (11161).
|
Theoretically, acerola might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Acerola contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption (11566). This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time (9804,9806). Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant (9805,9806,11566,11567). The vitamin C content of acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and warfarin is unlikely.

Theoretically, Boswellia serrata might increase the levels of CYP1A2 substrates.
Details
In vitro research shows that Boswellia serrata gum resin inhibits CYP1A2 enzymes (21178).
|
Theoretically, Boswellia serrata might increase the levels of CYP2C19 substrates.
Details
In vitro research shows that Boswellia serrata gum resin inhibits CYP2C19 enzymes (21178).

Theoretically, Boswellia serrata might increase the levels of CYP2D6 substrates.
Details
In vitro research shows that Boswellia serrata gum resin inhibits CYP2D6 enzymes (21178).
|
Theoretically, Boswellia serrata might increase the levels of CYP3A4 substrates.
Details
In vitro research shows that Boswellia serrata gum resin inhibits CYP3A4 enzymes (21178).
|
Theoretically, Boswellia serrata might alter the effects of immunosuppressive drugs.
Details
Some in vitro research suggests that Boswellia serrata extracts might inhibit mediators of autoimmune disorders such as leukotrienes and reduce production of antibodies and cell-mediated immunity (12432,12435,12437,12438). However, other in vitro research suggests that, when coupled with calcium ions, boswellic acids containing the keto group have immunostimulant properties within specific cell signaling pathways (21180).
|
Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen (14806). Bromelain is thought to have antiplatelet activity (10639,14806,18285,18286,37234). Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement (110547).
|
Theoretically, bromelain might increase levels of tetracycline antibiotics.
Details
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg (14296).
|
Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
Details
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage (110781).

Below is general information about the adverse effects of the known ingredients contained in the product Nutrilite Glucosamine HCl with Boswellia. 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, acerola seems to be well tolerated.
However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Acerola has been linked with one case of anaphylaxis and one case of rectal obstruction.
Gastrointestinal ...Osmotic diarrhea and gastrointestinal upset have been reported with doses of vitamin C greater than the tolerable upper intake level (UL) of 2000 mg daily (4844). Theoretically this could occur with large doses of oral acerola. A case report describes rectal obstruction with mass consisting of partially digested acerola fruits in a 5-year-old child who had ingested an unknown quantity of fruits daily for 7 days. The child presented with vomiting, abdominal pain and distension, tenesmus, constipation, and dehydration, and required surgical disimpaction (93205).
Immunologic ...There is a case report of a 37 year old man who developed a pruritic rash, dyspnea, and tachycardia 5 minutes after drinking a mixture of apple and acerola juices. He had a history of hay fever, oral allergy symptoms with avocado, celery, walnut, and curry, and contact urticaria with latex, but tolerated apples and apple juice. IgE antibodies to acerola were identified in the patient's serum. Ultimately, cross-reactivity between a latex protein and acerola was determined (93206).
General
...Orally, Boswellia serrata extract is generally well-tolerated.
For information on the safety of Boswellia serrata when applied topically or used as aromatherapy, see the Frankincense monograph.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, headache, heartburn, itching, nausea.
Serious Adverse Effects (Rare):
Orally: Large amounts of Boswellia serrata gum resin can cause bezoar formation.
Dermatologic ...Orally, Boswellia serrata extract (5-Loxin) has been associated with itching at doses of 100-250 mg daily (17948).
Gastrointestinal ...Orally, Boswellia serrata extract may cause diarrhea, nausea, abdominal pain, and heartburn (1708,12432,12438,17948,17949,17950,21149,109567). A case of a large gastrointestinal bezoar has been reported in a 17-year-old female who chewed and swallowed large quantities of boswellia gum resin (Boswellia species not specified) for celiac disease (36914).
Musculoskeletal ...Orally, Boswellia serrata extract (5-Loxin) has been associated with one case of foot edema and four cases of generalized weakness in one clinical study (17948).
Neurologic/CNS ...Orally, Boswellia serrata extract may cause dizziness, headache, and vertigo. In one clinical study, nearly 11% of patients taking a specific Boswellia serrata extract (K-Vie) reported headache. Dizziness and vertigo were also reported, but at lower rates (109567). In another study, headache was reported in one patient taking a specific Boswellia serrata extract (5-Loxin) (17948).
Psychiatric ...Orally, one case of mania is reported in a 73-year-old male who took Boswellia powder mixed with honey for 3 days. The patient recovered after hospitalization and treatment with olanzapine (110526).
General
...Orally, bromelain seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, flatulence, gastric upset, headache.
Topically: Pruritus, urticaria.
Dermatologic
...Topically, bromelain may cause dermal allergic reactions including urticaria, pruritus, and skin swelling (9184).
Redness, swelling, burning, pain at the application site, and cellulitis have also been reported rarely (108148,113513). In one case, a fixed drug eruption with pruritis near the groin was reported in a 33-year-old male taking bromelain 50 mg orally daily for 10 days. After discontinuation of bromelain and treatment with topical corticosteroid, the lesion resolved. Upon re-challenge with bromelain, the lesion reappeared in the same area (103300).
In another case report, a 61-year-old male with a history of chronic lower leg ulceration secondary to chronic venous hypertension and recurrent deep vein thrombosis on rivaroxaban presented with a deep-dermal burn on his lower calf. Bromelain-based topical enzymatic debridement agent Nexobrid 2 grams was applied to the burn site. Thirty minutes later, the patient experienced two instances of hemorrhage at the site of debridement. The patient was stabilized and treated with fluids, packed red cells, and tranexamic acid, and then the Nexobrid was removed (111656). Caution should be used in patients with underlying coagulopathies.
Gastrointestinal ...Orally, bromelain may cause gastrointestinal disturbances, including diarrhea, nausea, vomiting, flatulence, and abdominal pain (9184,18274,18282,96216,113513).
Immunologic
...Immunoglobulin E (IgE)-mediated allergic reactions to bromelain may occur (9184).
If inhaled, bromelain may cause sensitization and allergic reactions such as asthma (37199,37215,37233). In case reports of occupational inhalation of bromelain, additional allergic symptoms included difficulty swallowing, throat itching, eye irritation, and rhinitis (37214).
General
...Orally, lemon is well tolerated in amounts commonly found in foods.
A thorough evaluation of safety outcomes has not been conducted on the use of larger amounts.
Most Common Adverse Effects:
Orally: Epigastralgia and heartburn with the regular consumption of fresh lemon juice.
Dermatologic ...Topically, the application of lemon oil might cause photosensitivity, due to furocoumarin derivative content. This occurs most often in fair-skinned people (11019).
Gastrointestinal ...Orally, fresh lemon juice, taken as 60 mL twice daily, has been reported to cause gastrointestinal disturbances in 37% of patients in one clinical trial, compared with 8% of patients in the placebo group. Specifically, of the patients consuming lemon juice, 21% experienced heartburn and 8% experienced epigastralgia, compared to 1% and 3%, respectively, in the placebo group (107489).
