Review: It’s simple and effective - I’ve been using AlgaeCal 4-in-1 Vitamin D3 K2 Complete and really like how convenient it is to get D3, K2, A, and E all in one supplement. The softgels are easy to swallow, gentle on my stomach, and feel high quality. I appreciate the focus on bone strength and immune support without needing multiple vitamins. Simple, effective, and easy to stick with.
Review: Best D3 Vitamin Supplement - I have been taking this supplement for 7 months now and the results are amazing. I have gone from deficiency to normal level. Would highly recommend this product.

## Features

- Balanced Vitamin D3: It’s essential to keep Vitamin D3 in balance with Vitamin A, Vitamin E, and Vitamin K for healthy blood pressure, optimal bone health, robust immunity, cardiovascular well-being, and the maintenance of radiant skin, nails and hair.
- Vitamin D3: Unlike standard vitamin D supplements, D3 Complete harmonizes 1000 IUs of Vitamin D with its essential counterparts: Vitamins A, E, & K. When taken together these 4 nutrients are greater than the sum of their parts.
- Vitamin A & E: Vitamin A to support a youthful appearance and a robust immunity. Also boasts superior Vitamin E (Mixed Tocotrienols from the annatto plant of South America). This Vitamin E is a powerful antioxidant, shielding your cells against free radical damage. This, when taken with Vitamin D, helps to support a healthy complexion, a fortified immunity and stronger bones.
- Vitamin K: with a robust 5,550 mcg blend including Vitamin K2-4 & K2-7. Helps keep calcium out of your arteries, ensuring smooth blood flow. This is a key factor in maintaining healthy blood pressure.
- Quality Assured: Made in the USA with premium ingredients from Switzerland, Norway, Italy, and South America following the highest manufacturing standards. 60 easy-to-swallow softgel capsules. Packaging is recyclable.

## Questions & Answers

**Q: I already take a multivitamin with A, D, E, and K. Will I get too much if I take D3 Complete?**
A: No need to worry. D3 Complete is carefully formulated to provide optimal amounts of each nutrient. Plus, the vitamins are balanced to work together, which maximizes their health benefits.

**Q: Is the vitamin K2 sourced from natto?**
A: No, AlgaeCal D3 Complete uses plant-derived Vitamin K, processed with medium-chain triglycerides for superior absorption. It provides the same bone and heart benefits as natto-derived K2, without soy allergens.

**Q: Why only 1000 IUs of vitamin D?**
A: Recent research shows that high doses of D3 can backfire—leading to lower bone density and a higher risk of falls. That’s why a balanced dose, combined with other fat-soluble vitamins, is both safer and more effective. Balance is key to nutrients!

**Q: I heard Vitamin A is bad for you. Is that true?**
A: Only if you take too much. Research shows that excessive Vitamin A can cause side effects, but the safe upper limit for adults is 3,000 mcg—that’s five times the amount in one softgel of D3 Complete. So you’re well within safe levels!
