insightsAnalysis

Daily Amino Acid from 21st Century provides a spectrum of amino acids, including branched-chain amino acids (BCAAs) like L-Leucine, L-Isoleucine, and L-Valine, alongside other crucial ones like L-Lysine and L-Phenylalanine. These are the building blocks for proteins in the body, which are fundamental for many bodily processes.

The product also includes 300mg of calcium, derived from calcium carbonate and dicalcium phosphate, contributing to mineral intake. This combination aims to offer foundational support, suitable for individuals seeking a general amino acid presence in their diet without focusing on high, targeted doses of specific amino acids for specialized needs.

thumb_upPros
  • Offers a wide array of essential and non-essential amino acids.
  • Includes 300mg of calcium per serving.
  • Extremely low price per serving, making it very accessible.
  • Provides 120 servings in one bottle.
thumb_downCons
  • Individual amino acid doses are generally quite low.
  • The calcium source includes calcium carbonate, which may have varying absorption rates for some people.
  • May not be potent enough for those seeking significant support for specific amino acid deficiencies or performance goals.
warningWarnings
  • Individuals sensitive to amino acid supplements may experience mild digestive upset.
  • Those with specific health conditions, especially involving kidney function, should consult a professional before using amino acid supplements.
  • Phenylalanine is present; individuals with Phenylketonuria (PKU) should avoid this product.

flagReport overview

Categories

Calcium 65
The product provides 300mg of calcium per serving from a blend of calcium carbonate and dicalcium phosphate. This is a helpful amount to contribute to daily calcium needs, especially considering the product's primary focus isn't solely calcium.
storefront View products
Leucine 55
L-Leucine is present at 105mg per serving, which is a low amount compared to what is often used for muscle protein synthesis support. It provides a basic presence rather than a functional dose.
storefront View products
Valine 55
L-Valine is included at 58mg per serving. As with other BCAAs in this product, the dose is modest and serves more as part of a general blend rather than a targeted significant contribution.

Goals

flag Bone Health 60
The product includes 300mg of calcium, which contributes to daily calcium intake and can support bone health. However, this amount might not be sufficient for individuals with higher calcium needs or specific bone density concerns as a standalone supplement.
flag Nail Health 55
Amino acids are the building blocks for keratin, a primary component of nails, and calcium is also important. While this product provides these, the individual amino acid doses are relatively low for a noticeable impact on nail health.
flag Energy 50
Amino acids are involved in various metabolic pathways that contribute to energy production. However, the relatively low doses of individual amino acids in this blend may not provide a significant or immediate boost in energy for most users.
