HelloPharmacist Scorecard of Metabolic Complete by Enriching Gifts

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 7 of its 18 active ingredients.
  • “GR8CF-77 Enzyme & Mineral Blend” is a proprietary blend — the label gives one combined amount (75 mg) without saying how much of each component you get.

Metabolic Complete contains 18 ingredients, including digestive enzymes (shark cartilage, bromelain, protease, lipase, lactase, cellulase, invertase, and diastase), CoQ10, plant extracts (cat's claw bark, grape seed, maritime pine bark, and kelp), and mineral or enzyme blends. The product also contains inactive ingredients — gelatin capsules and magnesium stearate — that serve as a capsule material and flow agent.

The digestive enzymes are meant to help break down different food components: bromelain breaks down proteins, lipase handles fats, lactase splits milk sugar for people with lactose sensitivity, and others assist with carbohydrates and other nutrients. CoQ10 is an antioxidant your cells naturally produce; cat's claw, grape seed, and pine bark extracts are plant compounds with various traditional uses; and kelp adds minerals and iodine.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Lactose intolerance — rated "Effective" (Lactase) (Natural Medicines).
  • On file: Coenzyme Q10 deficiency — rated "Likely Effective" (Coenzyme Q10) (Natural Medicines).
  • On file: Asthma — rated "Possibly Effective" (Maritime Pine) (Natural Medicines).
  • On file: Chronic venous insufficiency (CVI) — rated "Possibly Effective" (Grape) (Natural Medicines).
  • On file: Migraine headache — rated "Possibly Effective" (Coenzyme Q10) (Natural Medicines).

Lactase is the only ingredient rated Effective — it works for lactose intolerance by helping you digest milk sugar. CoQ10 is rated Possibly Effective for fibromyalgia, migraine headache, heart failure, and diabetic nerve pain, and Likely Effective for CoQ10 deficiency.

Grape seed extract is Possibly Effective for chronic venous insufficiency (heaviness and swelling in the legs from poor blood flow), and maritime pine bark is Possibly Effective for osteoarthritis, chronic venous insufficiency, and asthma. For most other ingredients — shark cartilage, bromelain, protease, cat's claw, and kelp — the evidence is rated Insufficient; we cannot say whether they work for the conditions they're traditionally used for.

The data we hold does not establish effectiveness for most of the product's ingredients.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 10 of the 10 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 10 of 10.
  • General safety write-ups exist for 10 of 10.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most digestive enzymes in this product are generally well tolerated short-term. Bromelain, protease, and lactase can rarely cause allergic reactions in sensitive people.

Shark cartilage is often poorly studied and may cause nausea, constipation, dizziness, or taste disturbances; serious but rare effects include liver inflammation and low blood sugar. CoQ10 is generally well tolerated, though gastrointestinal upset, dizziness, and insomnia have been reported in small numbers of people.

Cat's claw and maritime pine bark have limited long-term safety data but appear generally well tolerated in short-term studies; rare reports link cat's claw to kidney injury. Kelp's high iodine content can disrupt thyroid function and may concentrate heavy metals from seawater.

During pregnancy, shark cartilage, bromelain, cat's claw, maritime pine bark, and kelp should be avoided due to insufficient safety data or active concerns. Grape seed extract is rated Likely Safe, and lactase is rated Likely Safe in pregnancy.

During breastfeeding, most of these ingredients have limited data; kelp should be avoided because iodine passes into breast milk and may affect the baby's thyroid. Talk with your doctor or pharmacist about any use during pregnancy or while nursing.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 7 of the 10 matched ingredients can interact with medications — Cat's Claw, Grape, Fucus Vesiculosus, Bromelain, Shark Cartilage, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,245 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check these medication types with your doctor or pharmacist: blood thinners and antiplatelet drugs (due to bromelain, cat's claw, grape seed, maritime pine bark, and kelp); warfarin specifically (due to CoQ10); chemotherapy drugs, especially alkylating agents (due to CoQ10); blood pressure medications and calcium channel blockers (due to CoQ10 and cat's claw); immunosuppressants after transplant or for autoimmune disease (due to shark cartilage and cat's claw); lithium, antithyroid drugs, thyroid hormone, and amiodarone (due to kelp's iodine content); and medications metabolized by CYP3A4, CYP2D6, CYP2E1, or CYP1A2 enzymes — a broad group that includes many common drugs (due to cat's claw, grape seed, and kelp).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Metabolic Complete is a multi-ingredient digestive enzyme and plant extract supplement. It may help if you have lactose intolerance or are interested in the other ingredients' possible effects on circulation, arthritis, or migraines — though evidence is limited for most.

Because it contains multiple ingredients that interact with blood thinners, heart drugs, immunosuppressants, thyroid medications, and chemotherapy, you should check your exact medications against the interaction tool on this page before taking it. Talk with your own doctor or pharmacist about whether it's right for you, especially if you take any prescription drugs, have a thyroid condition, or are pregnant or breastfeeding.

Cat's Claw bark extract6 drug types · 962 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, cat's claw may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Cat's claw contains rhynchophylline and isorhynchophylline. Animal research suggests that these alkaloids can inhibit platelet aggregation. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking cat's claw with antihypertensive drugs might increase the risk of hypotension.
Cat's claw contains rhynchophylline. In vitro and animal research suggests that rhynchophylline can lower blood pressure. This interaction has not been reported in humans.

Likelihood Probable Evidence D
Calcium Channel Blockers

Theoretically, taking cat's claw with calcium channel blockers might increase the risk of hypotension.
Cat's claw contains various alkaloids, including rhynchophylline, isorhynchophylline, corynoxeine, and isocorynoxiene. Animal research suggests that these alkaloids can lower blood pressure by acting as calcium channel blockers. This interaction has not been reported in humans.

Likelihood Probable Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, cat's claw might increase or decrease the levels and effects of drugs metabolized by CYP3A4.
Cat's claw may affect the clearance of drugs metabolized by CYP3A4. In vitro research shows that cat's claw can inhibit CYP3A4 enzymes. In one case report, a patient taking cat's claw (at an unspecified dose) experienced increased serum levels of atazanavir, ritonavir, and saquinavir, all of which are CYP3A4 substrates. Levels returned to normal 15 days after discontinuation of the cat's claw supplement, suggesting inhibition of CYP3A4 by cat's claw. In contrast, animal research suggests that rhynchophylline, an alkaloid contained in cat's claw, induces CYP3A expression and accelerates the metabolism of nirmatrelvir, the active component in the nirmatrelvir/ritonavir combination product.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, cat's claw might interfere with immunosuppressive therapy.
In human and laboratory research, cat's claw has been shown to have immunostimulating activity. It stimulates phagocytosis and increases respiratory cellular activity and the mobility of leukocytes. Theoretically, this could interfere with the activity of immunosuppressant medications.

Likelihood Possible Evidence D
Nirmatrelvir/Ritonavir (Paxlovid)

Theoretically, cat's claw may decrease the levels of nirmatrelvir.
Cat's claw contains rhynchophylline. Animal research suggests that this alkaloid induces CYP3A expression, thereby accelerating the metabolism of nirmatrelvir, the active component in the nirmatrelvir/ritonavir combination product. This interaction has not been reported in humans.

Likelihood Possible Evidence D

Grape seed ext.9 drug types · 910 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, grape extracts may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that grape extracts might decrease platelet aggregation.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Ingesting grape juice with cyclosporine can reduce cyclosporine absorption.
A small pharmacokinetic study in healthy young adults shows that intake of purple grape juice 200 mL along with cyclosporine can decrease the absorption of cyclosporine by up to 30% when compared with water. Separate doses of grape juice and cyclosporine by at least 2 hours to avoid this interaction.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, grape juice might reduce the levels of CYP1A2 substrates.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of CYP1A2.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, grape seed extract may increase the levels of CYP2D6 substrates.
In vitro evidence suggests that grape seed extract might inhibit CYP2D6 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, grape seed extract might increase the levels of CYP2E1 substrates.
In vitro and animal research suggests that grape seed proanthocyanidin extract inhibits CYP2E1 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

It is unclear if grape seed extract inhibits or induces CYP3A4; research is conflicting.
In vitro evidence suggests that grape seed extract might inhibit CYP3A4 enzymes. However, evidence from animal research shows that grape seed extract may induce CYP3A4 in the liver. So far, these interactions have not been reported in humans.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, long-term intake of grape seed extract might decrease the effects of midazolam.
Animal research shows that subchronic ingestions of grape seed extract can increase the elimination of intravenous midazolam by increasing hepatic CYP3A4 activity. Single doses of grape seed extract do not appear to affect midazolam elimination.

Likelihood Possible Evidence D
Phenacetin

Grape juice might decrease phenacetin absorption.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of cytochrome P450 1A2 (CYP1A2).

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

It is unclear if grape juice or grape seed extract inhibits CYP2C9; research is conflicting.
In vitro evidence shows that grape seed extract or grape juice might inhibit CYP2C9 enzymes. However, a small pharmacokinetic study in healthy adults shows that drinking 8 ounces of grape juice once does not affect the clearance of flurbiprofen, a probe-drug for CYP2C9 metabolism. The effects of continued grape juice consumption are unclear.

Likelihood Unlikely Evidence D

Kelp9 drug types · 891 drugs

Amiodarone (Cordarone)

Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Fucus vesiculosus contains high concentrations of iodine. 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. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Possible Evidence D
Lithium

Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium. Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using thyroid hormone could alter the effects of thyroid hormone.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.

Likelihood Unlikely Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C8. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C9 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C9. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP3A4. This interaction has not been reported in humans.

Likelihood Possible Evidence D

Pine bark ext.3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, maritime pine bark extract might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Clinical research suggests that maritime pine bark extract inhibits platelet aggregation. However, the clinical significance of this effect is unclear.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, maritime pine bark extract might increase the risk of hypoglycemia when used with antidiabetes drugs.
One clinical study shows that maritime pine bark extract decreases blood sugar in patients with diabetes being treated with antidiabetes agents. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, maritime pine bark extract might decrease the effectiveness of immunosuppressant therapy.
In vitro and animal research suggests that maritime pine bark extract has immunostimulant activity. This effect has not been reported in humans.

Likelihood Possible Evidence D

CoQ103 drug types · 198 drugs

Alkylating Agents

Coenzyme Q10 has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals.
Theoretically, antioxidants such as coenzyme Q10 might protect tumor cells from chemotherapeutic agents that work by inducing oxidative stress, such as alkylating agents (e.g., cyclophosphamide) and radiation therapy. The clinical importance of this interaction is unknown.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Coenzyme Q10 is chemically similar to menaquinone and might have vitamin K-like procoagulant effects, which could decrease the effects of warfarin.
Concomitant use of coenzyme Q10 and warfarin might reduce the anticoagulant effects of warfarin. Four cases of decreased warfarin efficacy thought to be due to coenzyme Q10 have been reported. However, there is some preliminary clinical research that suggests coenzyme Q10 might not significantly decrease the effects of warfarin in patients who have a stable INR.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, coenzyme Q10 might have additive effects with antihypertensive drugs.
Some clinical research shows that coenzyme Q10 can significantly lower blood pressure, although other studies have shown conflicting results.

Likelihood Possible Evidence B

Bromelain2 drug types · 141 drugs

Anticoagulant/Antiplatelet Drugs

Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. 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.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, bromelain might increase levels of tetracycline antibiotics.
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.

Likelihood Possible Evidence B

Shark Cartilage1 drug type · 121 drugs

Immunosuppressants

Theoretically, shark cartilage might interfere with immunosuppressive therapy.
In vitro evidence suggests that shark cartilage might stimulate immune responses. This effect has not been reported in humans.

Metabolic Complete by Enriching Gifts: Common Questions

Does Metabolic Complete by Enriching Gifts interact with any medications?
Yes. Based on its ingredients, Metabolic Complete has a known interaction with 1,244 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Metabolic Complete contains 18 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe to take while pregnant?
Several ingredients — shark cartilage, bromelain, cat's claw, maritime pine bark, and kelp — should be avoided in pregnancy due to insufficient safety data or active concerns. Grape seed extract is rated Likely Safe, and lactase is rated Likely Safe. Talk with your doctor or pharmacist before taking this product if you're pregnant or planning to become pregnant.
What does CoQ10 do in this formula?
CoQ10 is an antioxidant your cells naturally make. It's rated Possibly Effective for fibromyalgia, migraine headache, heart failure, and diabetic nerve pain, and Likely Effective if you have a CoQ10 deficiency. Most people tolerate it well, though nausea and dizziness have been reported in small numbers of users.
Can this help with digestion?
The product contains multiple digestive enzymes — bromelain breaks down protein, lipase handles fats, lactase splits milk sugar, and others assist with carbohydrates. However, the evidence that these enzymes improve digestion when taken as supplements is not well established in the data we hold for most of them.
What's lactase in this supplement for?
Lactase is an enzyme that breaks down lactose, the sugar in milk. It's rated Effective for lactose intolerance — if you have trouble digesting dairy, lactase can help. It's generally well tolerated, though rare allergic reactions have been reported in people sensitive to the enzyme itself.
Is this product safe while breastfeeding?
Limited safety data exist for most of these ingredients during breastfeeding. Kelp should be avoided because iodine passes into breast milk and may affect the baby's thyroid. Check with your doctor or pharmacist before taking this product while nursing.
What are the most common side effects?
Digestive upset — including nausea, constipation, diarrhea, and gas — is the most common concern across these ingredients. Dizziness and headache have also been reported. Stop taking it and tell your pharmacist if you have any symptoms that concern you.
