Consumer advice
If you need vitamin D3 and K2, this product works—but shop around first. A generic Nature Made or Nutricost D3 K2 combo will do the same job for $12-18 instead of $30. If you're already buying from Micro Ingredients for other products, the bundle discount makes this more reasonable. Check your vitamin D blood levels before supplementing; if you're not deficient, supplementation won't provide additional benefit. Take with a fat-containing meal to maximize absorption of these fat-soluble vitamins."
