AG1 Vitamin D3 K2 Drops, 1000IU of Vitamin D3 and 100mcg of K2 per Serving, Supports Bone Density and Calcium Absorption (Athletic Greens)

Great Product and Value 600 servings that can be easily taken with anything If you’re like me and live in a State that barely has any sun this is a god send for keeping those Vitamin D levels up!!

This is the best Vitamin D supplement I could find. My rheumatologist recommended a patch after failing to get my levels up from deficiency using pill supplements. I opted to try a liquid form first because I’m outside a lot and patches don’t stay on well. It became very clear my body absorbs this form much easier. After 3 months we tested my levels again and they shot right up!! My hair is thicker, my skin is back to a more olive looking tone - I couldn’t be happier. Taste isn’t bad at all - kind of tastes like olive oil - and I don’t get a tummy ache even if with skipping breakfast here and there.

Well I know that taking these are nice and convenient, I don't know how effective this is but it appears to be doing something, I'm actually satisfied with it though.

These drops work great! I’ve tried D3 supplements for years because my levels are always low. This is the first time my levels have gotten into the “normal” range. My D3 levels were 20.7 ng/ml (low) in November and now in March they are 42.5 ng/ml (normal). And I can feel the difference. I’ve been taking 10,000IU as daily (as long I remember to take it) but will probably lower the dose to 6000IU now that my levels are normal. I’ve been using the unflavored drops. It doesn’t taste great but it isn’t offensive. Like taking a teaspoon of olive oil. Initially I tried to hide it in my drinks and meals but didn’t like how it changed their flavor. I’ve found it is easier to down a dropper full then follow it with my morning coffee or breakfast. No weird aftertaste even when I don’t.

AG1 is a terrific product, no taste best to drop UNDER your tongue for better absorption.

These are the only vitamin d supplement that actually has raised my overall blood level of vit d !

Decent product, though wish it weren't 'oil' based. Probably will use a different brand when I need to replenish.

This is a nice, flavorless supplement that is super concentrated so you only have to take 2 drops per day. Just started it so I'm not sure how well it's working but my vitamin D was very low so hoping for some improvement. No side effects just yet. This small bottle will last a long time with the dosage being so small.
