Vitamin K2 and D3 easy to take softgels

Just started taking this a little over a month ago so I'm hopeful this will bump up my D3 its been low recewntly. Vitamins have become a daily regimen for me and make a difference after age 50. Sam's Club has a good variety and pricing on most of their vitamins. Pleased with it so far.

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.

Vitamin D

My vitamin D level was low so I started taking this product and at my next physical my level was where it needed to be.

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.

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.

Best value

Great value. I have been supplementing with this daily for last 9 months. Recently had my bloodwork checked and was in the optimal range for vitamin d using 1 dose per day. Highly recommended.

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!!

Made with inflammatory sunflower oil

First ingredient is inflammatory sunflower oil. Why not just MCT oil which is also a main ingredient? Hard pass
