If you’ve ever asked Elizabeth Tringali, PA-C what supplements she actually takes every day, this is your answer.
As a Functional Medicine expert with locations in Palm Beach Gardens and West Palm Beach, Elizabeth sees thousands of patients navigating the overwhelming world of supplements, and she has a clear philosophy: quality over quantity, bioavailability over marketing, and clinical evidence over hype. Most people don’t need a cabinet full of supplements. They need the right ones, in the right forms, from a source they can trust.
That’s exactly why Elizabeth custom-formulated the Vibrant Health supplement line: provider-formulated products designed to meet the standards she holds herself to, and the standards her patients deserve.
Here are the five functional medicine supplements Elizabeth recommends most, and why each one earns its place in her daily routine.
1. Vibrant D3/K2
The Foundation of Immune and Bone Health
Key benefits: bone density, calcium utilization, cardiovascular health, immune support
If there is one supplement that shows up as deficient in nearly every patient Elizabeth sees, it’s Vitamin D. Despite living in sunny South Florida, most people are still chronically low — and the consequences go far beyond bone health.
Vitamin D3 (the active, more potent form) supports immune system regulation, cardiovascular function, and mood. But here’s what most people miss: taking D3 without K2 is only half the equation. Vitamin K2, specifically in the MK-7 form, acts as a traffic director for calcium — helping it go where it belongs (your bones) rather than where it doesn’t (your arteries).
VIBRANT Liquid D3 with K2 pairs 1,000 IU of D3 with 10 mcg of K2 as MK-7 in a convenient, tasteless liquid formula. You can take it straight on the tongue or stir it into any beverage. It’s one of the most elegant, low-barrier ways to address one of the most widespread nutritional deficiencies in modern health.
2. Vibrant Omega
The Cleanest Fish Oil You’ll Ever Take
Key benefits: systemic inflammation reduction, brain health, cardiovascular protection, mood support
Omega-3 fatty acids — specifically EPA and DHA — are foundational to reducing systemic inflammation, supporting brain health, and protecting cardiovascular function. The problem isn’t that people don’t know omega-3s are important. The problem is that most fish oil supplements on the market are oxidized, poorly absorbed, or contaminated with heavy metals and pesticides.
Vibrant Omega sets a different standard. Sourced from the pristine waters off the Chilean coast — the world’s least industrialized coastline — each soft gel delivers 820 mg of EPA and DHA in the natural triglyceride form, which research shows is significantly better absorbed than the synthetic ethyl ester form found in most bargain fish oils. Every batch is vacuum distilled and independently tested for heavy metals, PCBs, and pesticides. It’s also stabilized with vitamin E and rosemary extract to prevent rancidity — a problem that plagues cheaper fish oils and can actually do more harm than good.
From an inflammation perspective alone, Vibrant Omega is one of the most impactful supplements you can take.
3. Vibrant Multivitamin
Not All Multivitamins Are Created Equal
Key benefits: micronutrient repletion, energy production, immune function, methylation support, antioxidant protection, bone and metabolic health
Most multivitamins are a waste of money — not because the concept is wrong, but because the execution is poor. Cheap, poorly absorbed forms of vitamins and minerals (think magnesium oxide, folic acid, cyanocobalamin) pass through the body without being properly utilized, and may even interfere with normal metabolic processes.
The Vibrant Multivitamin was formulated to be different at every level.
Folate is provided as Quatrefolic™ (100% 5-MTHF), the biologically active form that can actually be used by the body — critical for anyone with MTHFR gene variants who can’t convert standard folic acid. Minerals are delivered as Albion® TRAACS® chelated complexes, which means they’re bound to amino acids and absorbed via active transport rather than passive diffusion. The formula maintains an optimal 2:1 magnesium to calcium ratio, which is rarely prioritized in conventional multis. It includes antioxidant protection via vitamin C, natural vitamin E mixed tocopherols, and carotenoids. And it contains the K2/D3 synergistic pair for bone and cardiovascular health.
Available with or without iron, so you can choose the right version for your body and your labs.
This isn’t a “check the box” multi. It’s a clinical-grade nutritional foundation for a wide range of health protocols.
4. Vibrant Tri-Mag
The 3 forms of Magnesium Your Body Has Been Missing
Key benefits: muscle relaxation, sleep quality, cardiovascular support, healthy blood pressure, blood sugar regulation, energy production
Magnesium is involved in over 300 enzymatic reactions in the body — everything from energy production and blood sugar regulation to muscle relaxation, sleep quality, and stress response. According to the NHANES Study, more than 57% of Americans fail to meet the USDA’s requirements for magnesium in the diet. Alcohol, coffee, sugar, chronic stress, and certain medications all deplete magnesium further.
But here’s where most magnesium supplements fall short: they use a single form — typically magnesium oxide, which is poorly absorbed and notorious for causing digestive upset. Vibrant Tri-Mag takes a more sophisticated approach, combining three distinct forms of magnesium — di-magnesium malate, magnesium citrate, and magnesium glycinate — each absorbed via a different pathway in the GI tract. This multi-pathway approach prevents the absorption bottleneck that limits single-form supplements and maximizes the amount your body can actually use.
The forms used in Vibrant Tri-Mag are Albion® mineral chelates, clinically shown to have 8.8x greater absorption than magnesium oxide. They’re also GI-friendly — no bloating, no cramping, no unwanted laxative effect that makes people give up on magnesium altogether.
If you struggle with sleep, muscle tension, anxiety, headaches, or blood sugar regulation, magnesium deficiency may be part of the picture.
5. Vibrant Spore IG
The Probiotic That Goes Where Others Can’t
Key benefits: muscle relaxation, sleep quality, cardiovascular support, healthy blood pressure, blood sugar regulation, energy production
Not all probiotics are equal, and most people are taking ones that don’t survive long enough to do anything meaningful. Traditional probiotic strains (like Lactobacillus and Bifidobacterium) are fragile. They can be destroyed by stomach acid before they ever reach the intestines where they’re needed.
Vibrant Spore IG uses spore-forming bacteria: Bacillus coagulans, Bacillus clausii, and Bacillus subtilis — that form a protective endospore shell, allowing them to survive stomach acid and arrive in the gut intact and viable. Once there, they work to promote a healthy microbiome, support bowel regularity, and relieve gastrointestinal distress. Research on B. clausii has even shown promising results specifically for SIBO (small intestinal bacterial overgrowth), one of the most common and underdiagnosed gut conditions.
What makes Vibrant Spore IG truly unique is the “IG” — serum-derived bovine immunoglobulins. These proteins bind to and neutralize microbes and toxins in the gut, providing a concentrated boost to mucosal immunity. This is particularly valuable for anyone dealing with gut permeability (leaky gut), mold illness, or immune dysregulation. The immunoglobulins essentially help reset immune tolerance at the mucosal level — something conventional probiotics simply don’t address.
It’s consistently one of the most loved products in the Tringali Vibrant Health supplement line, with patients reporting real differences in digestion, bloating, and overall gut comfort.
