HelloPharmacist Scorecard of Ultimate OmegaChoicePlus by OptiChoice
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
Ultimate OmegaChoicePlus contains 5 active ingredients: eicosapentaenoic acid and docosahexaenoic acid (two omega-3 fatty acids from fish oil), vitamin D3, astaxanthin (a carotenoid pigment), and a total omega-3 blend. These are delivered in a softgel capsule with inactive ingredients including fish oil concentrate, gelatin, glycerin, microemulsion technology (VESIsorb), sucrose, and natural color from annatto.
The omega-3 fatty acids support heart and brain health, while vitamin D3 is essential for bone and calcium regulation. Astaxanthin is included as an antioxidant.
Does it work?
Moderate evidence
Vitamin D3 is effective for treating bone and mineral disorders: familial hypophosphatemia, osteomalacia (soft bones), renal bone disease, rickets, and hypoparathyroidism. For astaxanthin, the evidence we hold is insufficient to rate it for age-related cognitive decline, macular degeneration, aging skin, Alzheimer's disease, athletic performance, or carpal tunnel syndrome.
We have no effectiveness ratings on file for the omega-3 fatty acids in this product.
How safe is it?
Well-documented data
Vitamin D3 is generally well tolerated at recommended doses, but very high doses over time can cause vitamin D toxicity with symptoms of high blood calcium, bone loss, vision problems, and in rare cases anemia. Astaxanthin is generally well tolerated in short-term studies, though long-term safety data are limited; common side effects in trials include belly pain, diarrhea, and red-colored stools.
Vitamin D3 is likely safe during pregnancy and lactation at recommended amounts, but only under your doctor's guidance. The safety data for astaxanthin in pregnancy and breastfeeding are not sufficient—the facts advise against use during both.
Talk with your doctor or pharmacist about whether this product is right for you before you start.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist or doctor if you take thiazide diuretics (water pills for blood pressure), heart rhythm medications like verapamil or diltiazem, digoxin, cholesterol drugs like atorvastatin, or the psoriasis medication calcipotriene. Additionally, if you take medications broken down by your liver (especially those metabolized through the CYP3A4 or CYP2B6 pathways), verify they're not affected before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Ultimate OmegaChoicePlus may help support bone health and provide omega-3 fatty acids, but it carries moderate interactions with several common medications, especially those for the heart and blood pressure. If you take a thiazide diuretic, heart rhythm drug, statin, or psoriasis medication, you need to check with your own doctor or pharmacist before starting this product.
Pregnant or breastfeeding individuals should discuss this with their healthcare provider beforehand.

Formulation
VESIsorb
6x better absorption
Astaxanthin is a super antioxidant 500 times more powerful than vitamin E. Vitamin D3 is essential for promoting bone health. Recent scientific discoveries show every cell in your body needs vitamin D for your optimal well-being.
The patented VESIsorb colloidal droplet delivery system dramatically improves absorption and bioavailability of DHA Omega-3, astaxanthin and vitamin D3 in the body. Higher absorption translates into optimal support for the cardiovascular system, healthy lipid metabolism, joint function, skin health, and vital antioxidant defense against oxidative stress.
Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease.

Ultimate OmegaChoicePlus by OptiChoice Drug Interactions
HelloPharmacist Interaction Report
Ultimate OmegaChoicePlus by OptiChoice contains vitamin D3 and astaxanthin, two ingredients with documented interactions.
The most serious concern involves vitamin D3 and thiazide diuretics (water pills), which together can raise blood calcium to unsafe levels. Vitamin D3 also interacts moderately with heart rhythm medications (verapamil and diltiazem), cholesterol drugs (atorvastatin), digoxin, the psoriasis medication calcipotriene, and theoretically with aluminum-containing products.
We could not check eicosapentaenoic acid, docosahexaenoic acid, total omega-3 fatty acids, or the essential fatty acids blend for interactions.
Read the full breakdown — every affected drug type, severity by severity
Astaxanthin may reduce the effectiveness of drugs broken down by your liver through two enzyme pathways (CYP3A4 and CYP2B6 substrates)—though this has been seen only in lab studies, not yet in people. Vitamin D3 also theoretically affects CYP3A4 substrates through the same mechanism.
Altogether, these interactions span 744 individual medications. You'll want to run your exact medications through the checker below before starting this product, especially if you take any heart, blood pressure, cholesterol, or psoriasis medications.

For each ingredient in Ultimate OmegaChoicePlus with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Vitamin D3
Aluminum
Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.
Atorvastatin (Lipitor)
Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.
Calcipotriene (Dovonex)
Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.
Digoxin (Lanoxin)
Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.
Diltiazem (Cardizem, Others)
Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.
Thiazide Diuretics
Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.
Verapamil (Calan, Others)
Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.
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.
