Best Vitamin D3 + K2 Supplements in 2026: Doctor-Reviewed Picks for Bone, Heart & Immune Health

By Dr Frank Yap, MD -
Image
Vitamin D3 and Vitamin K2 are two of the most commonly deficient—and misunderstood—nutrients today. While Vitamin D improves calcium absorption, Vitamin K2 determines where that calcium actually goes . That’s why taking Vitamin D without K2 may be incomplete—and in some cases counterproductive. After reviewing ingredient quality, dosing accuracy, brand transparency, and real-world user feedback, the following are the best Vitamin D3 + K2 supplements available in 2026 . Most people in the United States consume less than recommended amounts of vitamin D . An analysis of data from the 2017–2018 National Health and Nutrition Examination Survey (NHANES) found that average daily vitamin D intakes from foods and beverages were 4.3 mcg in men, 3.8 mcg in women, and 5 mcg (200 IU) in children aged 2–19 years ( NHANES 2017 - 2018 ). Why Trust This Guide? This review prioritizes supplements that meet four non-negotiable criteria : Uses Vitamin D3 (cholecalciferol) — not D2 Includes Vitam...

A meta-analysis of 3 studies (C19early 2025) concluded that CPC (CetylPyridinium Chloride) may significantly lower risk with  viral clearance . One study shows significant benefit. Meta analysis using the most serious outcome reported shows 83% [6‑97%] lower risk . Results are consistent with early treatment being more effective than late treatment. A study, published in Nature ( Takeda 2022 ) concluded that CPC (CetylPyridinium Chloride) may inhibit SARS-CoV-2 infection even at lower concentrations. Another team of international scientists has also demonstrated the usefulness of cetylpyridinium chloride-containing mouthwashes in inhibiting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and reducing the risk of viral transmission. The study is published in the Journal of Medical Microbiology (2022). A scientific review, published in the  Journal of Formosan Medical Association  (2022) also concluded that mouthwash containing CPC shows potential fo...

Ivermectin and Fenbendazole in the Treatment of Psoriasis? A Case Series of 13 Patients (2026)

By Dr Frank Yap, MD -
Image
Abstract Psoriasis is a chronic autoimmune condition affecting approximately 7.5 million individuals in the United States, with significant economic, physical, and psychological burdens. This case series reports on 13 patients who experienced notable improvements in psoriasis symptoms following treatment with ivermectin and/or fenbendazole, antiparasitic agents repurposed for this indication. Cases were derived from self-reported testimonials shared on social media platforms. Treatment durations ranged from 3 days to 3 months, with dosages varying between 6 mg ivermectin twice daily and combinations with fenbendazole. Rapid resolution of skin lesions was observed in most cases, with some achieving near-complete clearance. While these anecdotal reports suggest potential therapeutic efficacy, controlled clinical trials are warranted to validate these findings and elucidate underlying mechanisms. Introduction Psoriasis is a chronic inflammatory disorder characterized by hyperproliferation...

Quercetin and Bromelain for Allergies 2023

By Dr Frank Yap, MD -

More than 50 million Americans who live with seasonal allergies. These symptoms tend to crop up with the onset of tree allergy season, followed by grass and weed season, notes Kevin McGrath, MD, an allergist in private practice in Wethersfield, Connecticut, and spokesperson for the American College of Allergy, Asthma, and Immunology. "The combination of trees, grasses, weeds, and molds makes for a difficult spring for most allergy patients and leads to sneezing, congestion, postnasal drip, sinus pain and pressure, watery eyes, and fatigue," he says. The good news is that there are a myriad of over the counter treatments out there that help ease the debilitating symptoms that accompany seasonal allergies.   Related: Best Nasal Sprays for Allergies What is Quercetin and Bromelain?

Ozempic vs Wegovy vs Mounjaro vs Zepbound: Key Differences, Weight Loss Results & Which One Works Best in 2026

By Dr Frank Yap, MD -
Image
The era of GLP-1 weight loss drugs is no longer emerging—it’s already dominating modern medicine. In less than five years, medications like Ozempic, Wegovy, Mounjaro, and Zepbound have shifted obesity treatment from marginal success to clinically meaningful, double-digit weight loss backed by large-scale randomized trials . The numbers are not subtle. In pivotal studies, semaglutide (Wegovy) delivered ~15% average weight loss, while tirzepatide (Mounjaro/Zepbound) pushed results beyond 20%—approaching outcomes once only seen with bariatric surgery . At the same time, these drugs are showing cardiovascular risk reduction, improved glycemic control, and potential benefits across fatty liver disease, inflammation, and metabolic syndrome . Yet despite the hype, most comparisons online are superficial—and often misleading. These drugs are not interchangeable . They belong to different pharmacologic classes, target different hormone pathways, and produce meaningfully different outcomes in...

By Dr Frank Yap, MD -
Image
The landscape of obesity treatment has evolved dramatically with the introduction of advanced medical therapeutics like retatrutide (RETA, LY3437943), tirzepatide (Mounjaro), and semaglutide (Ozempic) . Glucagon-like peptide-1 receptor agonists and co-agonists, originally developed to manage type 2 diabetes, have shown remarkable efficacy in promoting weight loss, making them game-changers for obesity management. However, each drug has unique mechanisms, benefits, and potential applications, including emerging roles in cancer prevention. This article compares their mechanisms, clinical efficacy, broader health benefits, safety profiles, regulatory status, and practical considerations to help patients, clinicians, and informed readers understand how they stack up in 2026.

9 Best Calcium, Magnesium, Vitamin D3 and K2 Supplements 2026

By Dr Frank Yap, MD -
Image
Calcium, magnesium, vitamin D and Vitamin K2 are vitamin and minerals that are vital to several bodily processes. Though they occur naturally in a variety of foods, many people take supplements to help increase their intake. Benefits and uses 1. May support bone health Calcium is the main mineral in your bones, which hold more than 99% of your body’s calcium stores. Your body is constantly regenerating its bone tissue, so it’s important to consume an adequate amount of this mineral daily ( bones.nih.gov ). Magnesium plays a key role in converting vitamin D into its active form, which aids calcium absorption ( Trusted Source ). Therefore, you can minimize your vitamin D requirement by making sure you’re also getting enough magnesium. Research has confirmed higher magnesium intake helps reduce your risk of vitamin D deficiency by activating more of it.  A  groundbreaking 2017 review  compiled over 80 studies that show vitamin D3 and K2 together might be greater than...

It’s natural to have complex feelings about noticing signs of aging. You can embrace the beauty and privilege that it is to age, while also not love all of the physical changes that come along with it.  If you’d like to soften these signs but don’t want to go the injectables route, there are non-invasive products that can help. In the world of beauty products, there's perhaps no category more saturated than the anti-aging market. What to Look for in an Anti-Aging Product a. Vitamin C An antioxidant powerhouse, vitamin C is directly involved with collagen production in the body. Vitamin C is beneficial in anti-aging products for several reasons: It protects skin from environmental stressors, promotes cell turnover, and can fade dark spots which contribute to the appearance of aging skin. Products containing vitamin C can irritate sensitive skin, so be sure to start out using a low concentration if your skin is reactive. b. Retinoids Retinoids are a category of ingredients, and retin...

By Dr Frank Yap, MD -
Image
Nattokinase and Nattozimes are two supplements that are often marketed for their ability to support cardiovascular health. While they share similarities in name and origin, there are key differences between these two supplements that consumers should be aware of when considering which one to take. What is Nattokinase? Nattokinase is an enzyme that is derived from the Japanese fermented soybean dish called natto. Natto has been a traditional food in Japan for over a thousand years and is made by fermenting soybeans with a specific strain of bacteria called Bacillus subtilis natto. Nattokinase is produced during the fermentation process and is known for its ability to break down fibrin, a protein that is involved in blood clotting. This is why nattokinase is often marketed as a supplement that can help support cardiovascular health by reducing the risk of blood clots, to help lower cholesterol, reduce inflammation, and improve circulation.  Nattokinase for Blood Clots Nattokinas...
