• Adolescence is an important life-stage for bone health providing a unique opportunity to maximize mineral retention and prevent the risk of osteoporosis-related fractures later in life. Because calcium is becoming increasingly deficient in the diet due to decreasing milk consumption, a strong interest in functional food ingredients to enhance calcium utilization has emerged.

Fecal slurries were stored at -20°C until DNA was extracted. DNA was extracted from 50- 100 mg of fecal material using the FastDNA ® SPIN kit for Soil (MP Biochemicals, Irvine, CA).

Multiple samples were run and differentiated using 10-bp tagged forward primers. Initial PCR from fecal samples extracts was performed using high fidelity Phusion DNA Polymerase (NEB) and amplicons were gel purified (QIAEX II Gel Extraction Kit, Qiagen).

Sequence quality was considered low if the length was ⁇ 400 bp or if there were mismatches or ambiguities in the forward primer sequence. Sequences were analyzed using the QIIME pipeline that includes software from many sources that allows Operational Taxonomic Unit (OTU) and taxonomic assignment as well as a number of different beta and alpha diversity measures. Chimerslayer was used to remove chimeric sequences. The OTU assignments were made using the uclust method and furthest neighbor clustering with a 97% sequence similarity threshold.
• OFTU Operational Taxonomic Unit
• OTU sequences were obtained after sequence alignment using PyNast and the Greengenes core set. Taxonomic assignments were made using the RDP classifier at 80% confidence. Rarefaction analysis was used to obtain an estimation of sequence coverage of the community. Alpha biodiversity estimations (e.g., Shannon and Chaol indices) were calculated to compare subjects, with the caveat that PCR is being used to target the 16S rRNA gene results might have been biased and differences in sequence copy per genome would influence relative numbers. Community composition comparisons were made using "Fast UniFrac" analysis of both OTU and phylogenetic datasets.

Multiple samples were run and differentiated using a combination of 8-bp tagged forward primer and 8-bp tagged reverse primers using a step out protocol that uses two PCR runs. The first PCR specifically amplifies the 16S rR A gene from fecal samples extracts. Unincorporated primers and nucleotides were separated from PCR amplicons using Agencourt AMPure XP kit (Becker).
• the second PCR was used to add bitags to the amplicons (from the first run) that are needed for Illumina sequencing and purified again using the Agencourt AMPure XP kit. All PCR was performed using Q5® High Fidelity DNA Polymerase (New England Biolabs) to minimize error rate during polymerization. Purified amplicons were quantified by fluorometry after staining using the PicoGreen DNA Assay Kit. Amplicons from each sample were combined in equivalent quantities sequenced using the MiSeq instrument (Illumina).
• Taxonomic assignments were made using the RDP classifier at 80% confidence and the Greengenes database. Rarefaction analysis was used to obtain an estimation of sequence coverage of the community. Alpha biodiversity estimations were calculated to compare microbiota diversity within subjects under specific SCF treatments. Beta diversity comparisons between communities were made using "Fast UniFrac" analysis of phylogenetic distances as well as non-phylogenetic distance analysis using Euclidean distances. All alpha and beta diversity measures were made using equivalent number of taxa (based lowest number of sequences obtained from a single sample) that were randomly chosen using multiple rarefaction results (10 iterations).
• a total of 12,979,388 high quality merged sequences were obtained using MiSeq Illumina sequencing with an average of 77,720.9 sequences ( ⁇ 28,401) per sample, and ranged from 28,854 to 262,312 sequences per sample (Table 7). The lowest number of sequences obtained was 28,854 therefore all subsequent analyses were rarefied to 28,800 sequences per sample. To obtain a rarefied dataset, 10 iterations of randomly choosing 28,800 sequences from each dataset was performed then datasets were merge to obtain a set of 28,8000 sequences that were representative of each sample.

Significant differences were found between communities in samples from the beginning and end samples of diets D10 and D20 with their respective beginning samples using the Euclidean distances measured (Bray Curtis, binary Euclidean) but not the phylogenetic measures (Unifrac distances) (Table 1 1, results also shown in Figures 6-8). There were also significant differences in the Euclidean and Bray Curtis distances between the end samples of diet D20 compared to the end DO. End samples of diets D10 and DO also differed significantly but only using Euclidean distances.
