Jarrow Formulas Alpha Lipoic Sustain with Biotin comes in a 60-tablet format, with each tablet delivering 300 mg of alpha lipoic acid (as thioctic acid) alongside 330 µg of biotin (as d-biotin). The tablets are produced using a bilayer design that combines a quick-release portion with a sustained-release portion, meaning ALA is made available both promptly and gradually over time rather than in a single immediate dose.
The formula is non-GMO, vegan, and gluten free, making it suitable for those following plant-based or allergen-conscious diets. Biotin contributes to normal energy-yielding metabolism and normal macronutrient metabolism, as well as normal functioning of the nervous system — recognised nutrient reference values that reflect its established nutritional role.
Jarrow Formulas is a well-regarded US supplement brand with a long track record in producing precisely formulated products to consistent manufacturing standards. This tablet format requires no preparation and is well suited to those who prefer a straightforward supplement without powders or liquids.
