What does the data say about Vitamin K2 (MK-7) 100m... vs CoQ10 Supplement - Coe...?
These two products serve quite different purposes despite both sitting in the heart health category. Solgar's Vitamin K2 (MK-7) uses the menaquinone-7 form derived from natto, which stays active in the body far longer than cheaper MK-4 alternatives — the 100mcg dose is well-supported by research for directing calcium away from arteries and into bones. SuperSelf's CoQ10 comes in at 200mg of ubiquinone, the oxidised form that's been studied extensively for mitochondrial and cardiovascular support, though it's worth knowing ubiquinol is generally better absorbed, particularly as we age.
If you're already taking Vitamin D3 or calcium supplements, Solgar K2 at £26.88 makes genuine sense — K2 is what helps those nutrients do their job properly. Just be aware it contains soya and milk derivatives, so it's not suitable for vegans or anyone avoiding those allergens despite the vegetable capsule. SuperSelf's CoQ10 at £8.41 is the more accessible option for statin users or anyone over 40 noticing flagging energy levels, and it's vegan-friendly with UK-based GMP manufacturing. Scores are close — Solgar at 74/100, SuperSelf at 73/100 — but they're not really competing. Buy based on what you actually need.
Solgar's Vitamin K2 MK-7 100mcg is a well-regarded supplement delivering the most bioavailable form of K2 (Menaquinone-7 from natto) at a clinically relevant dose.
