Pure Free-Form L-Lysine, 500 Grams, One Ingredient
Lysine is one of the nine essential amino acids, which means your body has no pathway to build it. Every gram has to come from food or from what you put in your shaker. This is single-ingredient L-lysine powder: one gram per level scoop, 500 servings per tub, and nothing else in the jar.
What L-Lysine Supports
- Lean body mass. Lysine is incorporated into nearly every protein your body builds, so it plays a direct role in maintaining lean tissue and nitrogen balance.
- Collagen and connective tissue. Your body needs lysine to form collagen, the structural protein behind tendons, ligaments, skin, and joint cartilage.
- Calcium absorption. Lysine supports how well the body takes up calcium and helps it hold onto what it absorbs.
- Carnitine production. Lysine is a precursor to L-carnitine, the compound that moves fatty acids into the mitochondria to be burned for energy.
- Immune resilience. Lysine contributes to normal immune system function and everyday defense.
- Energy metabolism. Converted to acetyl-CoA, lysine feeds into the Krebs cycle, one of the body's core energy pathways.
Why Powder Beats Capsules Here
Five hundred grams of powder is 500 full one-gram servings. Matching that with 500 mg capsules means swallowing two capsules for every single gram. The powder dissolves into water, juice, coffee, or a protein shake, and it lets you dose exactly what you need rather than whatever fits in a capsule shell. For anyone taking lysine daily over months, the powder is also the cheaper way to do it by a wide margin.
What Is Actually in the Tub
One ingredient. No fillers, no excipients, no flow agents, no proprietary blends, no amino spiking. NutraBio prints a fully transparent label, batch-tests through a third party, and manufactures in its own GMP-certified, FDA-inspected facility in New Jersey rather than outsourcing to a contract packer.

How to Use It
Mix one level scoop (1 gram) into 8 oz of water or any beverage, once daily, or as directed by your healthcare provider. Because it is unflavored, it disappears into whatever you are already drinking. It stacks cleanly with collagen, vitamin C, whey isolate, or your usual intra-workout.

Frequently Asked Questions
How many servings are in NutraBio L-Lysine Powder 500g?
500 servings. Each serving is one level gram.
Does it have a taste?
It is unflavored. At a one-gram dose in 8 oz of liquid most people notice nothing at all.
When is the best time to take lysine?
Any time of day. Lysine is a foundational amino acid rather than a pre-workout, so daily consistency matters far more than timing.
Is this product vegan?
Yes. The L-lysine is not animal-derived and the powder contains no other ingredients.
Does it contain fillers or a proprietary blend?
No. The only thing in the container is L-lysine, and the exact amount is printed on the label.
How does the powder compare to the 500 mg capsules?
Same amino acid, different delivery. The capsules are more portable; the powder is more flexible to dose and substantially cheaper per gram.
Can I mix it with other supplements?
Yes. Unflavored lysine stacks well with collagen, vitamin C, protein powder, or an intra-workout without affecting taste.
Where is it made?
NutraBio manufactures it in their own GMP-certified, FDA-inspected facility in New Jersey.
