Do any of these apply to you?

These conditions require clinical oversight before supplementing. We take safety seriously — if any apply, we’ll still show you foundational options.

Includes: chronic kidney disease (CKD), liver cirrhosis, active hepatitis, chemotherapy, or radiation therapy

Do you take prescription blood thinners or anticoagulants?

Vitamin K2 and Ginkgo biloba both interact with anticoagulants. If you take these medications, we’ll adjust your stack to avoid complications.

Common blood thinners: Warfarin (Coumadin), Eliquis, Xarelto, Plavix, Pradaxa, daily aspirin therapy

Which best describes your current hormonal profile?

Your hormone environment — not your identity — determines your nutritional needs. Iron requirements, multivitamin type, and several supplements differ significantly between testosterone-dominant and estrogen-dominant physiology.

Do you have a thyroid condition, or do you need to avoid or limit iodine?

Iodine directly regulates thyroid hormone production. Too much iodine can trigger flares in autoimmune thyroid disease. We’ll select an iodine-safe multivitamin for you if needed.

Applies to: Hashimoto’s thyroiditis, Graves’ disease, hyperthyroidism, or if your doctor has told you to limit iodine

Do you have a fish or shellfish allergy?

Standard Omega-3, glucosamine, and collagen supplements are fish or shellfish-derived. If you have an allergy, we’ll recommend algae-based Omega-3, plant-based glucosamine, and vegan collagen alternatives — identical efficacy, no fish.

Do you require strictly vegan supplements?

Many capsules contain gelatin (animal-derived). Some vitamins use animal sources (D3 from lanolin, for example). If you’re vegan, we’ll select certified plant-based alternatives for your entire stack.

Do you eat eggs or red meat regularly?

Choline is essential for brain health, liver function, and cell membranes — and over 90% of Americans don’t get enough. The best food sources are egg yolks (~150mg each) and red meat (~100mg per 3oz serving).

You need 425–550mg daily. If you’re eating fewer than 2 eggs or 2 servings of red meat per week, you likely need supplementation.

Do you perform physically demanding work or athletics that stress your joints?

Heavy manual labor, running, weightlifting, team sports, or any activity that puts repeated stress on joints — knees, hips, shoulders. Glucosamine sulfate and chondroitin have solid RCT evidence for joint cartilage support (takes 4–8 weeks to work).

Do any of these apply to you?

Magnesium is a cofactor in 300+ enzymatic reactions and is depleted by stress, coffee, and poor sleep. 50% of Americans are below the RDA — and standard blood tests miss deficiency because only 1% of body magnesium is in the blood.

Have you ever had calcium kidney stones?

High-dose Vitamin C can increase oxalate production and raise kidney stone risk in susceptible individuals. If you’ve had calcium-based stones, we’ll adjust your Vitamin C recommendation and flag calcium dosing accordingly.

Are you 35 years of age or older?

CoQ10 production declines ~50% by age 40. It powers your cells’ energy production — especially heart muscle — and is also depleted by statin medications. We’ll add CoQ10 if you’re 35+.

If you’re 34 and feel like 35 applies to you — select Yes. Rounding up only means more support.

Are you 50 years of age or older?

Age 50+ brings specific nutritional gaps that standard supplementation doesn’t address:

• Taurine: Levels drop 80% over a lifetime — a landmark 2023 Science study linked this to aging itself
• Collagen: Production drops 25–40% by age 50
• Vitamin E: Antioxidant protection for cardiovascular tissue
• Lutein/Zeaxanthin: Eye protection against macular degeneration (leading cause of vision loss after 50)

Do any of these apply to you?

Blue light from screens accumulates damage to the macula over time. Lutein and zeaxanthin are the carotenoids that filter harmful blue light — most people don’t eat enough kale and spinach to offset modern screen exposure.

How often do you eat fatty fish?

Fatty fish (salmon, mackerel, sardines, herring) are the primary dietary source of EPA and DHA — the Omega-3 fatty acids that reduce inflammation, support brain health, and protect the cardiovascular system.

Important: ALA from flaxseed and walnuts does not substitute — human conversion to EPA/DHA is less than 10%.

Are you currently taking hormonal birth control or hormone therapy?

Hormonal contraceptives (the pill, patch, ring, injection) are among the most consistent nutrient depleters in the medical literature. They systematically reduce B6, B12, folate, magnesium, zinc, selenium, and Vitamin C — often over years, silently.

Do you take any of these medications regularly?

Common medications deplete essential nutrients — a phenomenon called Drug-Induced Nutrient Depletion (DIND). We’ll ensure your stack replenishes what your medications are taking away.

Select all that apply, or select “none” if you don’t take any of these:
