HelloPharmacist Scorecard of AstaFX by Purity Products
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.
What’s inside
Full disclosure
AstaFX has four active ingredients. AstaReal Astaxanthin is a carotenoid antioxidant sourced from algae.
Tocotrienols are a form of vitamin E with antioxidant properties. Black pepper extract (Bioperine) is added as a thermonutrient — a compound thought to support nutrient absorption.
The product also contains monounsaturated fat, which we could not fully evaluate. The rest is inactive ingredients: olive oil, plant-based capsule material, vegetable wax, vitamin E acetate, rosemary oil, and chlorophyllin.
Does it work?
Not established
The evidence we hold doesn't establish that AstaFX works for its intended purposes. Astaxanthin has insufficient reliable evidence for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome.
Tocotrienols show possibly effective evidence for diabetes, but possibly ineffective for high cholesterol. Black pepper is rated insufficient reliable evidence for hay fever, asthma, athletic performance, headache, depression, and diarrhea.
None of these ingredients have strong proven effectiveness in the data available to us.
How safe is it?
Well-documented data
Astaxanthin is generally well tolerated in studies, though long-term safety data are limited. The most common side effects are abdominal pain, diarrhea, and red-colored stool; a small number of trial participants at higher doses reported stomach pain.
Tocotrienols appear well tolerated orally with no adverse effects reported in trials, though long-term safety at supplement doses isn't well established. Black pepper is generally safe in food amounts; when used as a concentrated supplement, it's less well studied.
Reported side effects are rare and mild — burning aftertaste, indigestion, reduced taste perception, and in one case, an allergic reaction in a sensitive individual. Astaxanthin and tocotrienols both lack sufficient safety data for pregnancy, so the safety data advises against them during pregnancy.
For breastfeeding, astaxanthin should be avoided due to insufficient data, and tocotrienols should be avoided unless advised by your doctor. Black pepper from food is likely safe in pregnancy; concentrated supplements are not recommended without medical guidance.
Meds to double-check
Moderate interaction found
Before taking AstaFX, double-check if you're on propranolol (a beta-blocker for heart rate or blood pressure), seizure medication like phenytoin, nevirapine (an HIV drug), rifampin (a tuberculosis drug), cyclosporine (an immunosuppressant), pentobarbital or other sedatives, cholesterol drugs like atorvastatin, theophylline (an asthma/COPD medication), or blood thinners like warfarin. Black pepper can increase blood levels of these drugs.
Additionally, astaxanthin may theoretically decrease levels of medications broken down by liver enzymes CYP3A4 and CYP2B6 — a large group that includes many common drugs. Use the medication checker on this page with your specific prescriptions.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
AstaFX is most relevant if you're interested in antioxidant support, but the evidence for its specific claims is insufficient. The main caution is black pepper's interactions with heart medications, seizure drugs, and several others — a significant concern if you take any prescription medications.
Astaxanthin and tocotrienols aren't recommended during pregnancy or breastfeeding. Talk to your pharmacist before starting, especially if you're on any regular medications.

Bioperine Nature's Thermonutrient
Anticoagulant/Antiplatelet Drugs
Theoretically, black pepper might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit platelet aggregation. This has not been reported in humans.
Antidiabetes Drugs
Theoretically, black pepper might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that piperine, a constituent of black pepper, can reduce blood glucose levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.
Atorvastatin (Lipitor)
Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.
Cyclosporine (Neoral, Sandimmune)
Theoretically, black pepper might increase the effects and side effects of cyclosporine.
In vitro research shows that piperine, a constituent of black pepper, increases the bioavailability of cyclosporine. This has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.
Lithium
Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.
Nevirapine (Viramune)
Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.
P-Glycoprotein Substrates
Theoretically, black pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit P-glycoprotein.
Pentobarbital (Nembutal)
Theoretically, black pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.
Phenytoin (Dilantin)
Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.
Propranolol (Inderal)
Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.
Rifampin (Rifadin)
Black pepper might increase blood levels of rifampin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and serum levels of rifampin.
Theophylline
Black pepper might increase blood levels of theophylline.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of theophylline.
Amoxicillin (Amoxil, Trimox)
Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.
Carbamazepine (Tegretol)
Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.
AstaReal Astaxanthin
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP2B6.
In vitro research shows that astaxanthin induces cytochrome CYP2B6 enzyme activity in human hepatocytes. This effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes. This effect has not been reported in humans.
Tocotrienols
Anticoagulant/Antiplatelet Drugs
Concomitant use of tocotrienols with anticoagulant or antiplatelet agents might increase the risk of bleeding. However, this has not been reported in humans.
Taking tocotrienols orally inhibits experimentally-induced platelet aggregation in humans. Theoretically tocotrienols might increase the risk of bleeding if taken with antiplatelet or anticoagulant drugs. However, tocotrienols 400-800 mg daily have been used with aspirin and/or clopidogrel for 1 year with no clear cumulative antiplatelet effects and no reports of bleeding.
