One pill is all it takes.
Verified Purchase
Most multivitamins are lacking in calcium and vitamin D, so I was looking to supplement them. This is affordable, and it's convenient because one pill is enough! Taking 2-3 pills a day is a hassle, so I just use one. The pill is huge, so I cut it in half to give to my child.

It's more effective than taking medicine for lower back pain.
Verified Purchase
I've tried a lot of medications for lower back pain, but when I started taking a similar calcium and vitamin D supplement without asking anyone, I got better quickly, so I ordered this. I think I'll probably ask the same thing. I think it's much more effective than just taking a random medicine.

Beautiful complex
Verified Purchase
I order a larger jar - 90 pieces, it lasts longer, it's more profitable. Calcium is better absorbed with vitamin D3. I trust this company, I also take other vitamins. The quality is good, without taste or smell, 1000 mg dosage. I drink 1 piece per day. The packaging is large, you can drink it with two people.

This calcium supplement with vitamin D3 is designed specifically for a course. The ingredients are high-quality and well-dosed. It's especially beneficial for older adults for strengthening bones. After taking the course, you'll notice a noticeable improvement in the condition of your nails and hair. The combination of calcium and vitamin D3 is well-balanced. It addresses vitamin D3 deficiency and is easily absorbed.

Good calcium
Verified Purchase
The quality, ingredients, size, dosage, composition, taste, and packaging are all as described. The benefits for the body are enormous: my muscles don't get tired during workouts, they're stronger, and I have more energy. My sleep has improved. I'll recommend them to my family and friends. Thank you, iHerb, for the opportunity to order a wide selection of supplements. These are fantastic supplements of excellent quality for the whole family. I'm completely satisfied.

Huge Pills, but worth it
Verified Purchase
As I get older, I want to improve my bone health, so I ordered this supplement. I feel like I'm doing something good for my body that will protect me as I age. There are a good amount of pills in the package. I took off a star because the pills are massive-the size of my eye! Still, calcium is important so it's worth it.

Quality for your bones
Verified Purchase
I use it for calcium deficiency for bones. The supplement has a neutral taste, the package lasts a long time. The tablets are just a bit big, but the advantage is in the dosage
