Sports Research® Vitamin D3 + K2 w/Coconut Oil - Vegan Vitamin D 2500iu (62.5mcg) & Mk7 Vitamin K 100mcg for Bone & Immune Support - Vegan Certified · Non-GMO · Soy Free - 60 Softgels

Clinical trials typically use 1,000-4,000 IU daily (25-100 mcg). Sports Research Vitamin D3 + K2 with Coconut Oil delivers 2500 IU Vitamin D3 + 100mcg Vitamin K2 (MK-7) per softgel (1 daily), which we classify as Therapeutic relative to that range.

Vitamin D3 can interact with thiazide diuretics (increasing hypercalcemia risk) and may affect the dosing of medications for hyperparathyroidism. Vitamin K2 can reduce the effectiveness of warfarin (Coumadin) and other vitamin K antagonist anticoagulants — anyone on blood thinners must consult their physician before adding K2 supplementation. Statins may reduce CoQ10 synthesis but do not directly interact with D3+K2 at these doses.

At 2500 IU D3 and 100mcg MK-7, this is a well-tolerated daily dose with an excellent long-term safety profile in clinical research. Vitamin D toxicity (hypercalcemia) requires sustained intake above 10,000 IU/day — far above this product’s dose. K2 at 100mcg has no established tolerable upper intake level and is considered safe for continuous daily use in healthy adults.

Fat-soluble vitamins in a softgel with coconut oil are generally well tolerated. Rare users may experience mild nausea if taken on an empty stomach, which is easily avoided by taking with a meal containing dietary fat. The carrageenan-free plant-gel capsule eliminates a common irritant found in other vegan softgels, reducing GI sensitivity risk.

D3+K2 stacks well with magnesium (which supports D3 metabolism), calcium supplements, omega-3s, and multivitamins. Avoid stacking with additional standalone K2 supplements unless tracking total K2 intake carefully. This product also pairs well with a morning routine, as fat-soluble vitamins absorb best alongside dietary fat such as breakfast or a tablespoon of nut butter.

Take one softgel daily with a meal containing dietary fat for optimal absorption — though the included coconut MCT oil provides some fat even without a fatty meal. Do not exceed one softgel daily without medical supervision. Individuals with hypercalcemia, hyperparathyroidism, or sarcoidosis should consult a physician before supplementing with D3. Periodic blood testing of 25-OH-D levels is recommended for long-term D3 users.

Vitamin D blood levels rise measurably within 4–8 weeks of consistent daily supplementation. Bone health and calcium utilization benefits from K2 are cumulative, with clinical trials showing arterial and bone density improvements over 12–36 months. Immune function support from D3 may be more immediately apparent in winter months or for individuals starting from a deficient baseline.
