Hype Score
0 = legit, 10 = all hype
"It's a vitamin D3 and K2 supplement with added magnesium, zinc, B6, MCT oil, and ox bile to support absorption."
Bottom line:
Consumer advice
- • If you're considering this product:.
- • Get your vitamin D and K2 levels tested first—supplementing without deficiency may not help and high-dose D3 can accumulate to toxic levels.
- • Ask the manufacturer for the specific doses of magnesium, zinc, B6, MCT oil, and ox bile—these are not disclosed on the label.
- • If you want higher-dose K2, consider buying D3 and K2 separately; this product's 100 mcg K2 is below clinical trial doses.
