HoltraCeuticals Vitamin D/K
Brand: HoltraCeuticals · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product combines two essential nutrients, but the available data focuses specifically on the calcium content from the label. For calcium, the science is clear: it plays a critical role in bone health, but you need to be careful with dosing to avoid risks. Data on the vitamin D and K components is not available for this specific product.
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and it also helps your muscles relax and your nerves signal properly [NIH ODS]. This combination is designed to support your overall skeletal and neuromuscular system.
Safety profile
Data not available for this specific product's adverse events. However, the FDA has received 592059 total adverse event reports across all supplements [FDA data]. For calcium specifically, very high intakes can cause serious issues including poor muscle tone, poor kidney function, constipation, nausea, weight loss, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by assessing your total calcium intake from food and other supplements. Do not exceed the tolerable upper intake level without medical supervision. If you take medications like antibiotics or thyroid hormone, separate your calcium dose by at least 2 hours [NIH ODS]. We recommend consulting your healthcare provider before starting this supplement, given the potential for serious side effects at high levels.
