Liquid K2 D3 Drops by RK Formulas 1 oz • K2 (MK7) for Fast Effective Absorption • 4833 IU's Per Serving • All Natural Vitamin D - Tastes Great

This product helped me increase my vit D levels in a few months. I have been testing my levels every 6 months because I was deficient & now I am in the normal range!Also, I recently came across this information in Dr. Mercola's website: "In a June 22, 2020, Orthomolecular Medicine News Service press release,1 Damien Downing, president of the British Society for Ecological Medicine, outlines how we could resolve the COVID-19 pandemic in 30 days for about $2 per person, simply by taking affirmative action to raise vitamin D levels. The downside or risk of doing this is basically nil, while the potential gain could be avoiding another COVID-19 spike altogether."If we could arrange to give everyone vitamin D, and it failed to protect them, so what? The risk from not acting is much greater than the risk from acting," Downing says, adding: "If you caught the COVID19 virus right now, having a good vitamin D status (from already having taken a supplement) wouldReduce your risk of the disease becoming severe by 90%Reduce your risk of dying by 96%This is not 'proven' or 'evidence-based' until we have done controlled trials comparing it to placebo … But the data, already strong, has been pouring in since the start of the pandemic."Like he says, if it doesn't work, nothing lost but possibly everything gained. Worth a shot to keep all our immune systems strong and healthy.

Ever wonder why sicknesses are so prevalent in winter months? In the Northern hemisphere, even in sunnier places, because of the earth’s tilt we get less vitamin D from the sun. Vitamin D is absolutely necessary for our bodies and when we can’t get it from sunlight, it’s good to know there are little drops of “sunshine” available to help meet our needs. Obviously talk to your doctor or pharmacist and don’t take medical advice from Amazon reviews, but look into it for yourself. And then come back here to get a great concentration of D at a great price. Also the addition of vitamin K2 helps keep calcium going into your bones, where it’s needed to prevent osteoporosis.

I did before and after blood work. This is great!! I use five drops at night it lasted a very long time. This is my second order. I love the fact that it has peppermint and olive oil as a natural ingredient. I can't seem to taste the peppermint as its very light in flavor. It's very affordable and very effective! I will stick to this one as long as I can.

Great taste , doesn't taste like glycerin like every other drip vitamin. It absorbs well under your tongue and fast. I cannot prove its effectiveness without a doctor blood test or similar but I will update this when the day comes. Based on its absorption I am sure it's entering your body because it disappears when dripped under the tongue and if you let it sit there without swallowing it does go away in under 2 minutes. Much better option than pills. Recommended for anyone living in northeast with 6 months of winter.

I like that it’s only 2 drops so the value seems outstanding as it lasts a good while

This is so much easier than pills. Two drops of minty tasting oil per serving. Our vitamin D levels tested very low so we are supplementing. The price can't be beat either!

The absorption rate of this product is excellent. The Combination of D3 and K2 is more effective. This is a great value for the $$ and more importantly works.

I drop it directly under my tongue when it will go there. Some on my cheek, some on the bottle. Tastes great and easy to swallow tho
