I will buy these again in 400 days definitely!
I am very happy with these D3 tablets. Not only are they going to last over a year, but they are small tablets which means I can easily swallow them, even without a glass of water. I have noticed a difference in levels of tiredness and am so glad I added these vitamins to my daily selection. I would recommend these - great value.

Simply amazing!!
I’ve been taking these Vitamin D3 4000 IU tablets for a while now, and I’m really impressed with the quality. Each tablet is small and easy to swallow, and since it's one-a-day, it's super convenient to fit into my daily routine. With 400 tablets in the pack, it provides over a year's supply, which is great value for the price. I love that these are vegetarian-friendly and made in the UK, which adds to my confidence in the product. Since starting them, I feel more energized, and it’s nice knowing that I’m supporting my immune system and getting the Vitamin D I need. Highly recommend these if you're looking for a reliable, high-strength Vitamin D supplement!

Cracking value and genuinely tiny!
Living in the UK, a Vitamin D supplement is pretty much a must-have, especially through the winter. I’ve tried a few different brands, but this one is definitely a winner for a couple of reasons. The Highlights: Genuinely Micro: They aren't joking when they say these are "micro" tablets. At 6mm, they are incredibly easy to swallow—no more gagging on giant capsules that feel like horse pills. If you struggle with taking tablets, these are a total game-changer. Brilliant Value: With 400 tablets in the bottle, this is over a year’s supply for a very reasonable price. It’s one of those "set it and forget it" purchases where you don't have to worry about reordering every few weeks. Made in the UK: It’s always a bit of a bonus to know the supplements are manufactured locally to high standards. It gives you that extra bit of peace of mind regarding the quality. The Verdict: It’s a straightforward, high-strength supplement that does exactly what it says on the tin. No fuss, no weird aftertaste, and they’re so small you’ll barely notice you’ve taken them. For a year's supply, it’s absolute value for money. 5/5 – Highly recommended.

Warning
Please be aware that this is an extremely high dose of vitamin D. This is only really required by people with a medical vitamin D deficiency. I ordered these thinking the more vitamin D the better, but it appears that 2000% the recommended daily allowance can cause serious - even life-threatening - effects. The recommended dose for people without a clinical vitamin D deficiency is 10-25 micrograms. I gave a three star review because the product doesn't make this information immediately available, but if you need this for medical reasons, the pill size is nice and small and there really are a lot of pills for your money. Just check what your personal vitamin D requirements is before ordering these.

Years supply easy to swallow
Gel capsules. Easy to swallow. Years supply. Dr has put one of my granddaughters on them to so as I've got mine from here I got hers to. A years supply is good

Für mich ein Pflicht-Supplement
Nehme die jetzt schon länger. Keine ungewollten Nebenwirkungen und Unverträglichkeiten. Enthält kein Vitamin K2. Das sollte jedem bewusst sein und evtl. extra eingenommen werden. Ich mag die Produkte der Fa. WeightWorld, da ich sie sehr gut vertrage und das Preis-Leistungsverhältnis schätze.
