Frequently Asked Questions
Can I bring liquid vitamin D through airport security?
Small travel-sized liquids typically follow TSA 3-1-1 rules; bottles 3.4 oz (100 ml) or smaller can go in carry-on bags inside a 1‑quart zip bag. The Pure Therapro 0.5 fl oz and 20 ml bottles are usually within limits, but always confirm current TSA rules before flying and pack liquids upright and sealed to avoid spills.
Is liposomal or micellized D3 better for travel?
Liposomal and micellized formulations can improve absorption, which helps if your diet or digestion is disrupted during travel. They’re good choices for short trips when you want reliable uptake, but they are liquids that require careful packing. Choose capsules if you prefer leak‑proof convenience.
Is a high-dose weekly capsule safe for regular travelers?
High-dose weekly formulas can be convenient but are not universally appropriate. Products like the Metabolic Maintenance 25,000 IU capsule are intended for supervised use; you should consult your healthcare provider and monitor blood levels if using high-dose regimens, especially if you take other medications or have medical conditions.
