Omega-3 (EPA+DHA) reduces triglycerides, supports brain function, reduces systemic inflammation, and improves cardiovascular outcomes. Vitamin D3 supports testosterone production (low D3 is associated with lower testosterone), immune function, and bone health.

Quality & transparency
Why form matters
Medibro uses
D3 + K2 (MK-7 form)
Long-acting MK-7
Others often use
D3 alone or K2 as MK-4
Lower bioavailability
MK-7 has a 72-hour half-life vs. MK-4's 1-hour — meaning it's active in your system all week.
K2 directs calcium to bones rather than arteries. Without K2, high-dose D3 can lead to soft-tissue calcium deposits. MK-7 is the clinically preferred form.

Supplement Interactions
What can I safely combine this with?
K2 directs calcium (mobilised by Vitamin D) to bones and away from arteries. D3+K2 is the gold standard combination.
View Vitamin K2 →Magnesium activates Vitamin D. Most people are deficient in both — supplementing together dramatically improves Vitamin D efficacy.
Omega-3 enhances Vitamin D receptor sensitivity, making the same dose of D3 more effective.
⚕️ Always consult a healthcare professional before combining supplements with medication.
Stack Synergies
Science-backed pairings for better results
Required to activate Vitamin D — without it, up to 50% of D3 stays inactive in the body
Directs calcium deposited by D3 to bones rather than arteries — essential pairing
Fat-soluble co-absorption; omega-3 enhances D3 bioavailability and anti-inflammatory action
Synergies based on published nutritional science. Individual results may vary. Always consult a healthcare professional before combining supplements.
