Sports Research Vitamin D3 5000 IU
Sports Research uses coconut oil as the softgel carrier, which solidifies below ~76°F and leaves Amazon reviewers in northern states staring at cloudy, partially solid softgels during winter — cosmetic only, but alarming to first-time buyers. The 5,000 IU dose also can't be split: users who want a 2,000 IU maintenance dose must buy a different SKU entirely. A smaller group of iHerb reviews mentions coconut taste or smell bleeding through, and one reviewer reported an acne flare-up correlating with starting the product.
Nature's Way Sambucus Elderberry Gummies
The single most-repeated Amazon complaint is gummies arriving congealed into one mass — reviewers describe 'a big melted lump' or bottles 'hardened into one piece' during warm-weather shipping. Each 2-gummy serving also contains 3g of added sugar (6g at the max 4-gummy dose), which health-conscious reviewers flag; a zero-sugar variant exists but costs more. A smaller group of reviews mentions a plastic-like off-taste, suspected to be heat damage or bottle leaching during transit.

The Verdict
Choose Sports Research D3 for year-round preventive immune support — the evidence base for adequate vitamin D status and respiratory infection risk is substantially stronger than for elderberry, and cost per serving is one-tenth the gummy. Choose Nature's Way Sambucus as a short-duration add-on (3–5 days) at the first sign of cold or flu symptoms, where the 2019 meta-analysis shows modest duration reduction; the sugar load and heat-sensitive shipping make it a poor choice for daily year-round use.
