Sports Research Vegan Vitamin D3 + K2 offers a well-rounded, plant-based approach to daily wellness. This supplement is specifically designed for individuals following a vegan or vegetarian lifestyle, or anyone who prefers to avoid animal-derived ingredients like lanolin. It's also a great choice for those seeking a moderate, maintenance-level dose of vitamin D3 without the high amounts found in many other supplements.
The standout feature is its use of vitamin D3 sourced from wild-crafted lichen, a sustainable and truly vegan alternative. Combined with vitamin K2 and organic coconut MCT oil, this formula is designed for optimal absorption, ensuring you get the most benefit from each softgel. In real-world use, this translates to reliable daily support for immune function, bone health, and overall vitality, making it a simple addition to a health-conscious routine.
In terms of design, the Plantgels™ are easy to swallow and have a minimal aftertaste, which is a plus for those sensitive to supplements. The packaging is clean and functional, clearly listing all ingredients and certifications. The product is also Non-GMO Project Verified and free from common allergens like gluten and soy, which adds to its appeal for those with dietary restrictions.
While the 60-count bottle is convenient, heavy users might find themselves reordering frequently. Additionally, the 2500 IU dose is on the lower end, so those with a known deficiency should consult a healthcare provider for a higher-potency option. However, for everyday maintenance and preventive support, this strength is often ideal.

Sports Research Vegan Vitamin D3 + K2 delivers a robust 10,000 IU of plant-based D3 and 100 mcg of K2 (as MK-7) in a single daily softgel. This combination is designed for individuals seeking high-strength immune and bone support, particularly those with limited sun exposure or dietary restrictions. The formula is enhanced with organic coconut MCT oil, which not only supports nutrient absorption but also makes the softgels easy to digest.
What sets this supplement apart is its vegan sourcing: most Vitamin D3 is derived from lanolin, but this product uses lichen, a sustainable and animal-free source. The inclusion of K2 (MK-7) is a smart addition, as it helps direct calcium to bones and teeth rather than soft tissues, enhancing the overall effectiveness for bone health. Users report that the softgels are easy to swallow and don't cause any aftertaste or digestive discomfort.
In terms of quality, the product is third-party tested, Non-GMO Project Verified, and free from gluten, soy, and carrageenan.

The high dose of 10,000 IU may be too high for some, especially if you're already consuming fortified foods or getting sun exposure. It's always wise to consult with a healthcare provider before starting high-dose supplementation.
One potential drawback is the price point, which is higher than synthetic alternatives. However, the clean, vegan formulation and the addition of K2 and MCT oil justify the cost for those prioritizing premium ingredients. The 60-count bottle provides a two-month supply if taken daily, making it a reasonable investment for your health.

This formula is designed for adults seeking comprehensive support for bone density, cardiovascular function, and immune health. It's an excellent choice for those who prefer a dual-nutrient supplement over taking separate pills.

Buying Guide
Potency and Dosage
Vitamin D3 dosage can range from a modest 1,000 IU to a robust 10,000 IU per serving. Your choice depends on your current levels, sun exposure, and health goals. NOW offers a lower 1,000 IU dose paired with 45 mcg of K2, ideal for maintenance or those new to supplementation. Sports Research provides multiple strengths, including 2,500 IU, 5,000 IU, and 10,000 IU, each with 100 mcg of K2. If you need a higher potency for immune or bone support, Sports Research gives you more flexibility.
Sourcing and Dietary Preferences
For vegans or those avoiding animal products, sourcing matters. Sports Research uses vegan D3 from wild-crafted lichen, making all their D3+K2 products suitable for plant-based diets. NOW derives its D3 from lanolin (sheep’s wool), so it is not vegan. If a plant-based label is essential, Sports Research is the clear winner. Both brands avoid common allergens, but always check individual product certifications.

Form and Absorption
Absorption of fat-soluble vitamins like D3 and K2 is enhanced when taken with oil. Sports Research includes organic coconut MCT oil in their softgels to improve bioavailability. NOW uses veg capsules without added oil, which may be fine if you take the supplement with a meal. However, the MCT oil in Sports Research products can boost absorption, especially for those with digestive concerns.
Value and Serving Size
Value is not just about price per bottle; consider the number of servings and potency per capsule. NOW’s 120-count bottle offers many servings at a low cost per capsule, making it a budget-friendly choice for a lower dose. Sports Research’s 60-count bottles provide a higher potency per softgel, which may mean fewer capsules per day. If you need a high dose, Sports Research can be more economical in the long run.

If you need a high-potency, vegan-friendly formula with enhanced absorption, Sports Research® Vegan Vitamin D3 + K2 w/Coconut (2,500 IU) or their 10,000 IU version are excellent options. For a budget-conscious, lower-dose supplement that still supports bone and immune health, NOW Supplements, Vitamin D-3 & K-2 delivers reliable quality at an accessible price point.
