Short answer: Zinc and Vitamin D3 round out Jelly Boost's formula as essential, well-established nutrients — supporting normal testosterone levels, muscle function and everyday vitality alongside the botanical ingredients.
Zinc: an essential mineral with a direct testosterone role
An essential mineral that supports normal testosterone levels, immune health and healthy cellular activity — one of the more directly evidence-supported ingredients in the blend.
Vitamin D3: broader hormonal and muscle support
Supports healthy muscle function, bone strength, immune wellness and normal hormonal activity — a foundational nutrient relevant well beyond just this specific formula's goals.
Why doses still matter here too
Exact per-serving amounts are not fully disclosed — the same transparency gap applies to Zinc and Vitamin D3 as to the rest of the formula's ingredients.
