## Description

Vitamin D, aka “the sunshine vitamin,” is a whole-body health superstar. Not only does it support a robust immune response and bone health, but vitamin D is also crucial for maintaining cognitive performance, supporting heart health (including maintaining your healthy blood pressure levels) and so much more. This value-sized vitamin D3 supplement delivers 25 mcg of vitamin D and contains 250 softgels, enough for an eight-month supply. This formula is made with 100% non-GMO ingredients.

Review: Easy to Take and Great Value for Daily Vitamin D - I’ve been using Life Extension’s Vitamin D3 for a few months now, and it’s become part of my daily routine. The softgels are tiny and easy to swallow, with no aftertaste at all. I appreciate that it’s non-GMO and gluten-free, which gives me more confidence in the quality. At 1000 IU per softgel, it's a great moderate dose for daily maintenance, especially if you’re not getting much sun. I feel more balanced and energetic since adding it to my supplement stack, and my last bloodwork showed my levels in a healthy range. Pros: Small, easy-to-swallow softgels Clean ingredients (gluten-free, non-GMO) Large bottle = great value for the price Trusted brand with consistent quality Cons: May be too low for those needing higher doses (though easy to take more than one) Overall, it’s a reliable, affordable choice for immune and bone health support. I’ll definitely repurchase.
Review: Supplements - Great value for the money! Easy to swallow! Size of pill is very small! Quality of the product is outstanding.

A great option for those who do not need a high dose of vitamin D but want steady daily support. Softgels have a small amount that makes it easy to adjust the dosage by changing the number of capsules. Formula is clean and gentle, suitable for everyday use. I use this brand because I genuinely trust it. Its products are consistently well-made and offer high quality.
