Vitamin D3: High-Potency Liquid

Every EquiLife supplement is formulated by Dr. Stephen Cabral, a Board Certified Doctor of Naturopathy with more than two decades of clinical experience helping clients through his private practice. Formulation starts from a simple standard: Dr. Cabral only creates products he'd give to his own family and his own practice clients. That means choosing the most bioavailable, body-ready forms of each nutrient (for example, methylated B vitamins), pairing ingredients that work well together, and refusing to cut corners on quality even when a better raw material costs more. It's a practitioner-first philosophy rather than a mass-market one.

We formulate with a clean-label standard, so most EquiLife supplements are gluten-free, all are non-GMO, and free from dairy, soy, egg, and nut ingredients, with no artificial colors, preservatives, or unnecessary fillers. Most of our products are also vegan. Because attributes vary by product, we list the specific dietary details right on each product page and label, so you can confirm the exact profile of anything before you buy.

Our formulas are grounded in published nutritional research, clinical experience, and functional-medicine principles. For each product, ingredients and dosages are selected based on the available scientific literature and Dr. Cabral's real-world clinical use - not on trends or marketing fads. Our goal is to give your body well-researched nutrients in forms it can actually absorb and use.

Yes, and we consider it non-negotiable. Every batch is tested by an independent lab before it reaches you. The laboratory testing screens include heavy metals, mold, and bacteria, checks for impurities, and confirms that the actual dosages match what's stated on the label (potency). It's how we can stand behind the purity, safety, and consistency of every bottle.

Our nutritional supplements are manufactured and stored in the United States at GMP facilities, under strict quality controls. We also keep production fresh, made in smaller, continuous batch runs every couple of months rather than products sitting in a warehouse.

You don't have to guess. Unlike a commodity supplement brand, EquiLife helps you personalize your path. You can start with our online quizzes and wellness protocols, work with our health coaches, or go deeper with at-home functional lab testing to understand your body's specific needs. From there, we help you build a routine designed around you—not a one-size-fits-all shelf product.

It depends on each case. Timing varies from person to person and product to product, and is influenced by your diet, lifestyle, baseline nutrient status, and how consistently you take the product. Some people notice changes relatively quickly, while foundational nutrition and longer-term goals often take more time and steady daily use. Consistency is the most important factor we’ve seen over the past 26+ years.

We ship across the United States and to 20+ International countries. Domestic orders over $99 ship free; orders under $99 are a $7.95 flat rate. Please allow about 3–5 business days for processing and shipping, with a little extra time for Alaska, Hawaii, and Puerto Rico. We ship supplements and protocols to more than 20 countries internationally (Australia, Austria, Canada, Denmark, France, Greece, Hong Kong, Hungary, Iceland, Italy, Latvia, Netherlands, New Zealand, Norway, Philippines, Romania, Singapore, Sweden, Switzerland, Taiwan, Ukraine, United Kingdom, Vietnam) and at-home lab tests to a smaller set (Australia, Canada, New Zealand, and the United Kingdom). International duties, taxes, and VAT are calculated at checkout. For the full country list and details, see our Shipping page.

Subscribing is the easiest way to stay consistent; which is the single biggest factor in getting results. When you choose the subscribe option on any eligible product, your order ships automatically on the schedule you select, and you'll save 15–20% on every recurring order versus one-time pricing. You're always in control: you can skip a shipment, change your delivery frequency, swap products, update your address or payment, or cancel anytime from your online account—no phone calls or emails required. And because your supplements arrive automatically, you never have to worry about running out mid-routine.

Yes. We stand behind every product with our "Empty Bottle 100% Satisfaction Guarantee." If you're not satisfied, simply return your empty bottles within 60 days of purchase for a full refund of your product purchase price (shipping and handling excluded). At-home lab tests are also refundable if returned before lab processing begins.
