Good Product Good Value

Better than I thought they would be. I like the 5000IU. Take one normally and two to plus up when battling colds. Seems to work very well - I’ll continue to buy and use this product.

Calcium’s Tour Guide

My functional medicine doc told me that Vit K2 acts as a tour guide for calcium - telling it to go to my bones and not my blood vessels. Wow. Why didn’t someone tell me this sooner. And as D3 and calcium work together as well, this is the perfect combo.

Vitamin D deficiency

I suffer from vitamin D deficiency. I get bad joint pain as well I’m not sure if it has to do with the vitamin D deficiency but I’ve been taking these daily and the pain has definitely lowered. I haven’t gotten new labs done to check my vitamin D levels but I feel better altogether and I haven’t gotten sick so it definitely helps with immune too.

Great Supplements for Heart, Bone & Immune Health!

Member's Mark consistently delivers high quality vitamins and minerals! As a vegetarian, I'm always excited to try supplements to boost my dietary health. I love that this combination of vitamins K2 and D3 will help support my heart, bone, immune, and muscle health The flip-top lid is a convenient timesaver. The small softgels are pleasant and easy to swallow, leaving no aftertaste. Very happy with this product.

Staying Healthy at a Great Value

My doctor recommended that I take Vitamin D supplements when my lab work showed I was deficient. I normally take just regular Vitamin D3, but this supplement also has K2 so that was a bonus for me. I’ve been taking this for over a month now and I like it. The pill is small and the dose is just once a day. It is a soft gel so it is also easy to take. I highly recommend this is if you are needing to supplement your Vitamin D intake.

Member’s Mark Better Than the Rest

These vitamin softgel capsules from Member’s Mark (Sams) are outstanding. First and foremost, these little gems are significantly smaller in size than most other vitamin brands, making them incredibly easy to swallow. Even better, they have no taste whatsoever, which makes daily consumption a breeze. What’s truly impressive is how they stack up against popular brands—in fact, they look strikingly similar to Nature Made’s version, and are also gluten-free, sugar-free, lactose-free, and free from artificial flavors and synthetic colors. That said, Member’s Mark takes it a step further with exceptional quality at an unbeatable price—they’re only a fifth of the cost of competitor brands.

Simple bottle, easy supplement!

Super easy to take on a regular basis. Soft gels makes it simpler to take as opposed to a hard pill. Strong Vitamin D content so it's good to have if you're slightly deficient. The bottle is easy open too if you have hand-strength problems.

would be an amazing product were it not for the inflammatory sunflower seed oil. beyond that it works as intended minus the inflammatory side effects. why not just use MCT, olive oil or coconut oil!?

Stop putting seed oil in Members Mark Brands

Dear Walmart/ Sam’s, Please stop putting seed oils in your supplements. Please stop selling supplements with seed oils. Please up the food wellness game at SAMS! When is SAMS going to align with the Alice L Walton School of Medicine? Walmart - stop selling JUNK! SAMS - start selling premium stuff without all the bad stuff in it! This is life and death vs profit!!
